Of 1,701 cattle tested with tuberculin, 319 reacted to the test — that is to say, gave evidence of tubercular infection— and 2 additional cattle were held as suspects for testing at a later date, about 19 per cent of all animals tested proving to be tuberculous. During the period from April, 1907, to June, 1909, inclusive, the Bureau of Animal Industry supervised the testing of 2,471 cattle in herds supplying milk to the District of Columbia. These tests gave 377 reactions, showing more than 15 per cent of the cows to be tuber- culous. In Virginia, from July 1, 1909, to June 30, 1910, 899 cattle THE MILK SITUATION IN THE mSTRICT OP COLUMBIA. 61 were tested, of which 162 gave indications of tuberculosis and 39 were held as suspicious, a percentage of 18.27 of all animals inspected being shown thereby to be affected to a greater or less degree with tuberculosis. During the same period the application of the test to 289 head of cattle in Maryland resulted in 48 reactions and 6 suspects, with a consequent percentage of 15.74. It is conspicuously noteworthy that during the same interval there were retested in Virginia 966 animals, of which 923 passed examina- tion, only 89 reacted, and 4 were held for further examination, mak- ing a percentage on the retest of 4.45, which result contrasts strongly with the percentage of 18.27 reactors and suspects among cattle sub- jected in the first instance to the test. A similarly remarkable improvement in the conditions of the herds, so far as infection with tuberculosis is concerned, was evidenced in Maryland, when on retest 301 animals successfully withstood the test, while only 5 reacted and 3 cases were suspicious, making a percentage, including those reacting and suspected, of 2.58, a marked reduction from the percentage of 15.74 shown in the original test. A retest of cattle in the District, embracing 455 individuals, showed 423 to be free from tuberculosis, 31 reacting, and 1 suspect, evidencing a very gratifying reduction in the percentage to 7.03. These examinations have demonstrated beyond question the feasi- bility of eliminating tuberculosis from existing herds at the con- clusion of not more than three or four tests. Frequently a herd has been found to be clear of tuberculous infection on a second test. Aside from the efficacy of the test in eliminating diseased cattle from the herds, the same examination gave convincing evidence of the remarkable accuracy and reliability of the application of tuber- culin in indicating infection with tubercle bacilli. In the tests made in the District of Columbia tuberculosis was demonstrated in cattle which reacted in something over 98 per cent of the cases, and in examinations of 126 cattle in and near the city of Washington tuber- cular lesions were found in 99.21 per cent of the cases which reacted, showing an error of but seventy-nine hundredths of 1 per cent. RESULTS or TESTS THROUGHOUT THE UNITED STATES. By consulting a statement prepared by the Bureau of Animal Industry, giving the results or the tuberculin testing of cattle by State and Federal officers, we find that between 1893 and 1908 there were tested 400,008 cattle in all parts of the United States. Of this vast number 37,000 head reacted to the test, yielding a percentage of 9.25 of all cattle tested. Of the number reacting, 24,784 were slaughtered under inspection, and upon post-mortem examination 24,387, or 98.39 per cent, of these were shown to be infected with bovine tubercle bacilli. At the Bethesda Experiment Station of the Department of Agri- culture a number of District herds, apparently in the best of health so far as evidenced by physical examination, were subjected to the tuberculin test, and 40 per cent of these animals reacted. The react- ing animals were shown to be intermittently expelling tubercle bacilli, and, since the commonest mode of expulsion of the bacilli from the body of the cow is with her feces, the very general contami- 62 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. nation of milk from this source during the ordinary process of milk- ing compels the conclusion that tuberculosis among dairy cows is one of the greatest dangers to which the public is exposed, and that every effort should be exerted to remove this very prevalent cause of the disease among human beings. The accuracy of tuberculin as a diagnostic agent has, as has been stated, been established in over 98 per cent of the cases tested. The only instances, generally speaking, in which it has not been efficient are when the disease is in an advanced stage and has become so gen- eralized that the ordinary dose of tuberculin has no appreciable effect with so much natural tuberculin in the system of the animal (in which condition the effects of the disease are usually clearly observable by visual examination), or when, by reason of the appli- cation of the tuberculin test shortly before, the animal fails to react or respond, which tendency to unresponsivejiess lasts generally about six weeks. The test is also inoperative in certain instances which are, however, as a rule clearly detectable by the vaterinarian when making the examination. It was represented by the milk producers and dealers at the hear- ings of the committee that the proposed enforcement of the tuber- culin test was impracticable and onerous for the reason that the reliability of tuberculin as a diagnostic agent had not been estab- lished, and for the further reason that, if the test be insisted upon, the milk producers would refuse to submit their herds to the test and would ship their product to Baltimore and other markets, caus- ing a permanent shortage in the milk supply of the District and a correspondingly increased price to the consumer, rendering it im- possible for the poorer classes to purchase milk, thereby comj^elling the use by them of prepared milks and other substitutes of alleged inferior quality. TUBERCULIN TEST MANDATORY IN DISTRICT OF COLUMBIA. It is perhaps not generally known to the public that the tuberculin test has been compulsorily applied in the District of Columbia; that is to say, that all cattle actually maintained within the boundaries of the District have been subjected to the test since ISTovember 27, 1909. This observation does not extend, however, to herds itt Maryland and Virginia, from which the major portion of our milk supply is obtained. On the date mentioned the District Commissioners issued a series of regulations (Appendix AB) providing for the compulsory tuberculin testing of all cattle within the District, as a result of which practically all the cattle in the District have now been sub- jected to the test. The first prosecution under the above regulations was undertaken in the local police court since the date that this committee commenced its investigations. The defendant was arraigned on the charge of violating section 4 of the regulations, in not permitting inspecting veterinarians to apply the tuberculin test to a cow on November 28, last. On an agreed statement of facts, argument w^as had result- ing in a verdict against the defendant. The defendant was not represented by counsel, and it is not known whether the case will be appealed. It is expected that the decision in this case will confirm THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 63 the right of the District authorities to enforce the above regulation against owners of cattle, even where the product is not offered for sale or used outside the owner's family. RELIABILITY OF TEST AFFIRMED BY AUTHORITIES. The tuberculin test, states Dr. Schroeder, is now almost universally accepted by veterinarians as a practically infallible means of diag- nosis, and while we know that all cases of tuberculosis diagnosed with the aid of tuberculin are not at the time dangerous and may not be- come so in some instances until many months have passed, we are obliged by the exigencies of the case to assume that, for all practical purposes, every tuberculous cow is dangerous from the moment she is known to be affected. It is not feasible, therefore, in eradicating tuberculous animals from existing herds, to distinguish between dangerously and not dangerously tuberculous cows. Since, however, from the viewpoint of the milk supply, this may, as has been stated, even when the animal is in the early stages of infection, be contami- nated, the advisability of at once segregating the diseased animal can not be questioned. It is interesting to note that animals of entirely healthy appearance, apparently fat, sleek, and well fed and with good appetites, may be already actually diseased with tuberculo- sis to a somewhat advanced stage, and that as a rule cows which are visibly tuberculous have very probably been dangerously affected for several years. The profound value of tuberculin in enabling an accurate diag- nosis of animals infected in a greater or less degree with tuberculo- sis is due, we may repeat for emphasis, to the fact that cattle, acting in all respects like healthy animals and whose bodily condition is apparently better than can be expected of ideal dairy cows that give large quantities of milk and have excellent appetites and no visible or audible respiratory difficulties, may have their tuberculous condi- tion revealed in this manner. It is only when the substances that are eliminated from their bodies — feces, saliva, milk, etc. — are sub- jected to microscopic and other tests that the proof is obtained of the dangerous character of the diseased animals toward the public health and the health of other animals. Authorities communicated with by the committee mainly agree that the tuberculin test affords a wonderfully accurate diagnosis of tuberculous infection in bovine animals. Dr. Perrow, health officer of Lynchburg, Va., is authority for the statement that one herd of 150 cows in Lynchburg showed only one reaction. On killing it was manifested that the animal reacting had one lung badly affected. It is interesting to note that 33 municipalities in the United States now require that herds which supply their milk be tuberculin tested and that the error in the application of the test has never been found in any of these jurisdictions to be greater than 3 per cent. Some communities which do not insist upon the application of the tuber- culin test require, nevertheless, that all animals coming into their jurisdiction to be used for dairy purposes be subjected to the test without reaction or be shown to have recently successfully withstood the test. During the past year laboratory experiments have been made by the Bureau of Animal Industry, testing by microscopic examination 64 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. and animal inoculation the glands of cattle which had reacted to the tuberculin test, but in which lesions were not found by ordinary post-mortem examination. In more than half of the cases tubercle bacilli were positively identified, showing that tuberculosis was really present in these carcasses in an incipient form, the lesions being too slight for detection by ordinary post-mortem examination. The per- centage of accuracy of the tuberculin test may be said, therefore, to be even higher than indicated by the figures previously stated. REPORT OF INTERNATIONAL COMMISSION ON CONTROL OF BOVINE TUBERCULOSIS. In this connection, reference should be made to the very valuable report recently submitted by the International Commission on the Control of Bovine Tuberculosis, an advance typewritten copy of which is in possession of the committee (Appendix AC), the report having not yet been printed for distribution. The report was not only agreed to without dissent by the members of the commission, but received subsequently the unanimous approval of the American Veterinary Medical Association at its recent convention in San Fran- cisco. The labors of the commission extended over the period of a year. At the meeting of the American Veterinary Association at Chi- cago, 111., in September, 1909, the following gentlemen were con- stituted an international commission to study the methods of the con- trol of bovine tuberculosis and to report its conclusions at the next annual meeting of the association. In order that all , interests af- fected might be adequately represented, the commission embraced among its personnel Senator W. C. Edwards, a member of the Ca- nadian Parliament and one of the most extensive live-stock breeders of the Dominion; J. J. Ferguson, chief of the animal husbandry work of Swift & Co., Chicago, 111.; J. W. Flavelle, head of one of the large packing companies of Canada; W. D. Hoard, editor of Hoard's Dairyman (a representative journal of the dairy interests) and a former governor of Wisconsin; C. A. Hodgetts, health officer of the Province of Ontario, Canada; J. N. Herty, secretary of the Indiana State Board of Health; Dr. John R. Mohler, chief of the pathological division. Bureau of Animal Industry, United States Department of Agriculture; V. A. Moore, professor of pathology, Cornell University; M. P. Ravenel, professor of bacteriology. Uni- versity of Wisconsin; M. H. Reynolds, professor of bacteriological science. University of Minnesota; E. C. Schroecler, superintendent of the Bethesda Experiment Station, United States Department of Ag- riculture; T. W. Tomlinson, secretary of the American National Live Stock Association ; F. Torrance, professor of bacteriological sci- ence. University of Manitoba; and J. G. Rutherford, veterinary director general of Canada. A cursory inspection of the make-up of this commission gives absolute assurance of the soundness of its con- clusions, and breadth of view is guaranteed by the diversity of inter- ests represented. Notwithstanding the participation in the labors of the commission, of recognized representatives of the packing and dairy interests, the report of the commission was a unanimous one. It is prefaced with a reference to the great economic and sanitary THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 65 significance of animal tuberculosis to the live-stock industry of America and the factors which must be accounted with in formu- lating successful measures for its eradication. The commission re- stricted its activities to the ascertainment of reasonable and economi- cally practicable methods or systems to be recommended to both officials and live-stock owners for eradicating this great scourge of domestic animals. It averts to the fact that tuberculous is increas- ing rather than declining among cattle and other animals, and, that . as this disease is one of the strictly preventable infections, there is good ground for the belief that, through the formulation and en- forcement of proper regulations, tuberculosis among animals may eventually be entirely suppressed. The commission recognizing, after careful study, that the tuber- culin test is the fundamental factor in any policy having for its object the control of bovine tuberculosis, recommends that, as a gen- eral policy, all contact between tuberculous and healthy cattle and between healthy cattle and stables, cars, etc., which may contain live tubercle bacilli, be prevented ; that there should be no sale or ex- change of animals affected with tuberculosis except for immediate slaughter (and for breeding purposes under official supervision) ; that all live-stock shippers should take every precaution to see that all cars furnished are thoroughly cleansed and disinfected before use ; that tuberculin properly used is an accurate and reliable diagnostic agent for the detection of active tuberculosis (though tuberculin may not produce a reaction when the disease is in a period of incubation, when its progress has been arrested, or when it is extensively gener- alized, which last condition is relatively rare and may usually be detected by physical examination) ; that all exposed animals should be retested at intervals of 6 months to 1 year; that the tuberculin test should not be applied to any animal having a temperature higher than normal; that any animal having given one distinct reaction to tuberculin should thereafter be regarded as tuberculous; that the subcutaneous injection of tuberculin is the only method of applying same for the detection of tuberculosis which can be recommended at the present time; that the injection of tuberculin has no injurious effect on healthy cattle; and that a positive reaction to tuberculin in any properly conducted test, official or otherwise, in, any animal in any herd shall be considered evidence sufficient upon which to declare the herd to be infected. The commission proceeds to recommend the passage of legislation providing for the comj)ulsory notification, by owners and veteri- narians, of the existence of tuberculosis in a herd, whether such in- formation result from clinical examination or from the tuberculin test, and favors the adoption of some system of marking, for the purposes of identification, of all cattle 3 years old or over shipped for slaughter. , In order to insure the eradication of tuberculosis the commission further specifies the necessity of separating healthy and diseased animals, maintaining that if a herd be found to be extensively in- fected, even the apparently healthy animals should be regarded with suspicion until they have been separated from the reacting animals for a period of at least 3 months, after the expiration of which those animals not reacting to the tuberculin test may be considered healthy and classified accordingly. 82444°— S. Doc. 863, 61-3 5 66 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. The commission suggests that a policy of compensation be pur- sued as useful, proper, and necessary, and as a temporary measure that, when tuberculosis exists in a herd to which a policy of slaugh- ter and compensation can not reasonably be applied, such herd be compulsorily dealt with by the owner under Government super- vision on the principle of the separation of all sound animals from those affected, and that in the event of anyone refusing or neglecting to comply with this requirement, his entire herd be closely quaran- tined and sales therefrom entirely prohibited ; that when slaughter is necessary, in order to avoid economic loss, every effort be made to utilize, as far as possible, the meat of such animals as may be found fit for food ; that, except when purchases are made from disease-free herds tested by a properly qualified individual, persons buying for breeding purposes or milk production, limit their purchases to ani- mals successfully withstanding the tuberculin test ; and that, in order to assist in properly carrying out this suggestion, official authorities adopt such regulations as will prevent the entry into their respective territories of cattle for breeding purposes or milk production unless accompanied by satisfactory tuberculin test charts. The commission further recommends that all milk and milk by-products used as food be properly pasteurized unless derived from cows known to be free from tuberculosis ; and, furthermore, that legislation be enacted inhibiting the sale, distribution, or use of tuberculin by any persons not acting with the full knowledge or under the direction of official authorities. The commission concludes with a recognition of the necessity for a widespread campaign of education on the subject of its deliberations and the importance of the cooperation of the press in convincing the public of the vital importance of the life of farm animals to the wel- fare of all classes of society ; and with a reference to the desirability of uniform legislation regarding the control and eradication of tuber- culosis, it being recommended that the laws of the United States, Canada, and other American countries governing the admission of animals from without be made stringent and assimilated, so far as possible, as well as those regulating the interstate and interprovincial movement of cattle. It dwells additionally upon the urgency of legislation to prevent the various frauds which interfere with the satisfactory use of tuberculin as a diagnostic agent and points to the necessity of making cattle as resistant as possible to infection by stabling them in clean, disinfected, and properly ventilated and lighted barns, giving them abundant, clean water, nutritious food, a sufficient amount of daily exercise in the open air, and by providing such other conditions as are well known to contribute to the health of animals, including the daily removal of manure from stables and the installation of water-tight floors and proper drainage. The foregoing recommendations were made by the commission with the primary purpose of eradicating tuberculosis among animals as an economic problem. The necessity for their adoption is magni- fied manifoldly when we consider tuberculosis among animals in its relation to the problem of conserving the public health. The commission concludes its report with the admonition that the eradication of tuberculosis among animals should have the approval and support of all persons who are interested in curtailing human THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 67 suffering and prolonging human life. The campaign of education recommended must, it urges, to be effective, be accompanied with a measure of disciplinary control, accomplished through conservative legislation calculated to insure active cooperation on the part of cattle owners and enforced with tact and determination. It may be concluded from the foregoing observations that the tuberculin test is a wonderfully accurate method of detecting tuber- culosis; that the application of tuberculin has no injurious effect upon healthy cattle, and that its employment in diagnosing the disease in animals makes possible the eradication of bovine tuberculosis. CONTEMPLATED ADVANTAGES OF THE TUBERCULIN TEST. The advantages which should result from the enforcement generally in a given jurisdiction of the tuberculin test are well specified by Surg. Gen. Wyman, of the United States Public Health and Marine- Hospital Service. He says: The enforcement of the tuberculin test would reduce the amount of tubercu- losis among dairy cattle and free the milk supply from tubercle bacilli, with the probable result that the incidence of tuberculosis among hogs fed on creamery skimmed milk would be reduced and the incidence of infection with the bovine tubercle bacilli among human beings would be practically eliminated. Freeman is authority for the statement that the enforcement of the tuberculin test will effect a marked diminution in infant mor- tality, which opinion is shared by Ravenel, Winslow, Vaughan, and Prescott, who include adults as well in their commentary, while the Chief of the Bureau of Animal Industry, the Surgeon General of the Army, and the Surgeon General of the Navy unite in the judg- ment that it may be used in a rational way to eradicate tuberculosis from cattle with good economic results to the live-stock industry. Dr. T. xA.lexander Geddes, who has pursued studies and observations on this subject in European countries, refers to the great advantage which would inure to the owners of herds from the fact that it takes less foodstuffs to produce results in a healthy animal than in a tuberculous one, which is especially true where glands of the intestinal tract are involved. Dr. Perrow, health officer of Lynch- burg, Va., calls attention to the difficulty of enforcing the test and enjoins that it be introduced gradually, while Dr. ^A'lieeler, health officer of Portland, Oreg., claims that it will, by removing diseased cattle from the market, give us better meat for table use. The en- forcement of the test would furthermore, it is observed by Dr. Babb, dairy and milk inspector of Topeka, Kans., aid in educating the people to greater caution among themselves with respect to human tuberculosis. Borden's Condensed Milk Co. takes the position that in the present state of the dairy business a general enforcement of the tuberculin test and the slaughter of reacting cows would pro- duce a great financial injury to the dairy business and a loss to the people of the country" in depriving a great majority of a large por- tion of their milk supply. The time is not ripe, in its opinion, for the inauguration of the test. The representatives of the Milk Pro- ducers' and Dairymen's Associations furnishing milk for local con- sumption claim that the requirement of the tuberculin test will result disadvantageously and lead to exorbitant prices for milk. 68 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. COST OF APPLYING TEST. Regarding the criticism that the making of the tuberculin test necessarily involves a considerable expense, which would work a hardship upon the owner of cattle if the test be demanded, it should be explained that the better part of two days is required in practice for effectually applying the test, irrespective of whether the herd comprises 5 or 50 head, requiring, if properly done, the actual attendance of the veterinarian during this period of time. How- ever, the expense of testing might, it is believed, be materially reduced by providing the requisite number of officials (under Fed- eral, State, or municipal direction) to make such tests, which plan, it is conjectured, would reduce the cost to the owner to $1.50 per head of cattle, regardless of the number of cattle in each particular herd. In the absence of such an arrangement it is manifest that the expense of having, for example, 2 or 3 cattle tested would be markedly greater than where a herd contains 20 or more individuals, since the time required to make the examination is approximately the same where a considerable number of animals is concerned as when a single individual is tested. The actual expense of applying the test, including the services of a veterinarian, depends largely upon the size of the herd tested and its convenience of access by the veterinarian. It is estimated by the Chief of the Bureau of Animal Industry that the test can prob- ably be made, if not done gratuitously by the Government, at an average cost to the owner of $1 per cow. Borden's Condensed Milk Co. intimates that it is practically impossible to make an intelligent suggestion as to the approximate expense unless the conditions under which the test is to be applied are given, but that, in general, if the herd is not oVer 3 miles distant from the office of the veterinary, the testing can be done for $15 on a basis of 25 cows in the herd, for $20 on a basis of 50 to 75 cows in the herd, and for $25 for 100 cows in the herd, including the cost of tuberculin, which is about 5 cents per test. SHOULD GOVERNMENT OR HERD OWNER DEFRAY EXPENSE OF TEST. There has been considerable discussion throughout the country as to whether, in the event of the insistence upon the tuberculin test, the cost of the test should be defrayed by the National, State, or Municipal Government, as the case may be, or by the herd owner. The Chief of the Bureau of Animal Industry asseverates that the Federal Government or the State should bear the expense of making the test when officially required in the interest of the public health, the Department of Agriculture being willing to test without charge herds supplying milk to the District of Columbia, and to extend cooperation so far as possible to State and municipal authorities elsewhere throughout the country. This view is coincided in by the Surgeon General of the Army and the Surgeon General of the Navy, while varying positions are taken in the matter by other authorities consulted by the committee, some contended that the States should undertake the expense for a fixed period ; others that, if compulsory, the Government should bear the expense, while, if voluntary, this should be assumed by the owner; while still others suggest that the THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 69 expense be shared equally by the Government and the owner. The president of the Milk Producers' Association supplying Washing- ton recommends that two-thirds of the expense be borne by the Government and one-third by the owner. Generally speaking, the expense of applying the test should, in the judgment of the committee, devolve upon the government (State or municipal). The necessary cost of testing would be slightly re- duced to the State or municipality by the furnishing gratuitously by the Bureau of Animal Industry of tuberculin for the purpose. In accordance with what is known as the " half and half " principle of appropriating for the needs of the District government, the cost should, so far as the testing of cattle supplying milk to the Wash- ington market is concerned, be provided, in the committee's view, one-half from the Federal Treasury and one-half from the revenues of the District of Columbia. It should be observed that many farmers, intent upon improving their herds and with a conscientious desire to furnish for consump- tion only milk of a high standard of purity calculated to be free from causation of sickness and mortality, have, up to the present time, voluntarily and anxiously submitted their cattle to the tuber- culin test, notwithstanding the fact that this expense on their part has been practically without appreciable advance in the price re- ceived by them for their output of milk or for the cattle tested. The indisposition on the part of certain farmers to submit their herds to the tuberculin test is not a matter of surprise, since it is the history of all reforms that objection, largely the result of preju- dice, is interposed to advances which are later universally recog- nized as advantageous, even by those who are at first strongest in their opposition to them. Aside from the large benefit which must, in the opinion of the committee, inevitably result to the milk- drinking public, there is a decided economic advantage in the long run to the cattle owner who, by the systematic application of the tuberculin test to his herd, greatly reduces and finally exterminates all tuberculous infection from his cattle. The intelligent farmer is beginning to recognize the ultimate advantage of having his herd free from constant decimation through the ravages of tuberculosis. COMPENSATION FOR CONDEMNED CATTLE. That it is an exceedingly difficult matter to arrive at a satisfactory solution as to the appropriate remuneration to the owner of cattle condemned as the result of reaction under the tuberculin test is evi- denced by the wide divergence of views expressed by authorities consulted by the committee. A consideration of much force adduced in opposition to the arbi- trary condemnation and slaughter without compensation of animals shown by the tuberculin test to be infected with tubercle bacilli is that, since the practical confiscation of private property is insisted upon with the avowed purpose of safeguarding and improving the public health, the owner of the condemned cattle should be fully com- pensated from the Public Treasury for losses sustained through such action. In Pennsylvania all animals reacting to the test are paid for by the State, and it is noteworthy that in this Commonwealth tuber- culosis among cattle is being eradicated with more success than in any 70 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. other State, and there are usually three times as many voluntary requests on file for the application of the test as can be made. It is suggested by Dr. Mohler, of the Bureau of Animal Industry, that provision should perhaps be made to pay 70 per cent of the price of all condemned animals, not to exceed $30 per head for common stock and $00 for registered stock. Dr. W. H. McLain, commissioner of health of Wheeling, W. Va., is inclined to the opinion that the owner should receive about 75 per cent of the value of cattle condemned as a result of the tuberculin test. The Chief of the Bureau of Animal Industry takes the position that owners should be compensated, at least in part, for cattle con- demned, and that the respective States where cattle are owned should make provision for compensation for cattle slaughtered as a result of the tuberculin test, several States having, he remarks, already laws providing for such compensation. Dr. Melvin refers to the basis of condemnation in recent cases in the District of Columbia, which may be briefly stated as follows : Cattle were appraised before slaughter, the appraisal not to exceed $75 for a pure-bred or registered animal, or $50 for a grade or unregistered animal. Eighty per cent of the appraised value, less the amount realized as salvage, was paid on cattle whose carcasses were passed for food on post-mortem inspec- tion, and 40 per cent, less salvage, in the case of cattle condemned for offal. If a reacting animal showed no lesions of tuberculosis on post- mortem examination, the full appraised value, less salvage, was paid. This arrangement was followed in carrying out the order of the District Commissioners " for the suppression and prevention of tuberculosis in cattle," dated November 26, 1909, and now operative in the District of Columbia, the regulations having received the approval of the Secretary of Agriculture on the following day. The committee is prepared to recommend this scale of compensation as best adapted to secure justice to the herd owner. The granting of an indemnity for animals shown by the tuberculin test to be diseased will do more toward making the test popular with cattle owners than any other possible action and will have the further incidental but mate- rially important effect, if tuberculosis can be eradicated from dairy herds with but slight loss to the owner, of making it unnecessary to materially increase the price of milk to the consumer or to deprive the children of the poorer classes wholly or partially of this necessary article of diet. EFFECT or COMPULSORY TUBERCULIN TEST ON PRICE OF MILCH COWS. It h<^s been urged that the enforcement of the tuberculin test with regard to all animals supplying milk to the District would result in a material augmentation of the price of milch cows, which have, it is alleged, experienced an increase from $35 to perhaps $65 per head during the past 10 years in this section of the country. There is a wide diversity of opinion as to the effect of the enforce- ment of the tuberculin test on the price of cattle, referring jjarticu- larly to the price of milch cows. It has been contended before the committee by a representative of the local Dairymen's Association that the price of cows would be increased from 20 to 30 per cent, while the president of the Milk Producers' Association has estimated 26 per cent as the probable advance in cost of cows. This contention THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 71 is not sustained, however, by the general consensus of opinion among authorities consulted by the committee. The Chief of the Bureau of Animal Industry invites attention to the fact that the price of cows, as well as of other things, has increased all over the country within recent years, regardless of whether the tuberculin test has been applied or not, the statistics of the Department of Agriculture showing that the average value of milch cows has increased from $30.67 per head on January 1, 1908, to $35.79 per head on January 1, 1910, a ratio of 16.7 per cent in two years. It is Dr. Melvin's opinion that while the price of cows might pos- sibly be affected if the tuberculin test were applied simultaneously over a large part of the country and all reacting animals slaughtered, the gradual application of the test, followed by slaughter, extending over a small area would have no perceptible effect upon prices. He takes the position, furthermore, that since all milk frdm tuberculous cows is unquestionably dangerous to human health and life a slight increase in p'rice of cows and in the cost of milk should not be con- sidered an adequate reason for refusing to remove this danger. He refers, besides, to the fact that cows affected with tuberculosis are usually not as productive as healthy cows and that their value as milk producers would probably steadily decrease. The State health officer of Florida opines that while the immedi- ate effect would be to raise the price, the ultimate tendency would be to conserve the health and vitality of the cattle and consequently reduce the price. Ravenel philosophically asserts that " a healthy cow is worth more than a sick one." Dr. Coit estimates that the enforcement of the tuberculin test would increase the price of cattle from 25 to 50 per cent. It is assumed that he refers to the effect of national enforcement, or the application of the test covering a very considerable territory, and not to the influence on the price of cattle which might reasonably be expected to follow the introduction of the test is so limited a terri- tory as the District of Columbia. The initiation of the test judi- ciously and gradually, not instantaneously and abruptly within so circumscribed an area as the District of Columbia, could even less reasonably be expected to produce the result predicted by Dr. Coit. Dr. C. J. Marshall, of the veterinarian department of the Uni- versity of Pennsylvania, expresses the belief that the enforcement of the tuberculin test, if generally applied, would undoubtedly increase the price of cattle for a few years. Dr. Goler, health officer of Rochester, N. Y., reports that the intro- duction of the test has had no effect yet in his jurisdiction, while Borden's Condensed Milk Co. expresses the belief, based upon its investigations in Massachusetts and other States where the enforce- ment of the test has been attempted, that it would very gi'eatly increase the price of cattle. Dr. Park, of New York City, makes the ingenious suggestion that in order to counteract as fully as practicable the increased price of cattle resulting from the introduction of the tuberculin teSt, the reacting cattle be at first separated (when in sufficient number to make this practicable) and their milk pasteurized and used. This course would undoubtedly, in his judgment, alleviate to some extent the effect on the price of cattle. 72 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. While the effect of the introduction of the tuberculin test on the price of cattle is problematical, it may be conservatively estimated with some degree of accuracy that the effect of the enforcement of the test gradually, as proposed, or only so far as applies to cattle furnish- ing milk to the District of Columbia, will be quite inconsiderable and will be counterbalanced by the increased value to be derived by the farmer for his stock already on hand and by the additional price received by him for his milk. COMMUNICABILITY OF HUMAN TUBERCULOSIS FROM BOVINE SOURCES. Much attention is being devoted at the present time, by segrega- tion and otherwise, to minimizing the danger among human beings of infection with tuberculosis from bovine sources, with the hope of ultimately eradicating the disease among humans. The prudence of removing this possible source of infection by expelling from exist- ing herds such animals as are shown to be affected with, tuberculosis in even its preliminary stages must appeal with force to every well- minded person. The elimination of the disease from among cattle by rigorous insistence upon segregation of tuberculous individuals is obviously more easy of accomplishment than among human beings, where our sympathy and commiseration leads us to ignore many well-established sanitary precautions for preventing contagion. It should be understood that the movement which is now progress- ing so successfully to oust all diseased animals from herds of milch cows, and indeed of neat cattle, is not only substantially in the inter- est of the public health, but will be found to be of decided advantage from an economic standpoint to the herd owner; for tuberculosis among animals, encouraged by conditions existing up to the present time, is not only increasing with alarming rapidity, often extending to every single animal in a herd and decimating its numbers with frequency, but experience shows that the amount and quality of milk derived from diseased animals is inferior to that which may be rea- sonably expected from healthy cattle maintained under proper sani- tary conditions. When it is estimated that 25 per cent of all cows furnishing milk to the District of Columbia are infected with tuber- culosis the importance of proceeding at once with firmness to the elimination of diseased cattle from such herds will be promptly recognized. There has been considerable dissension among the ranks of phy- sicians and sanitarians as to the communicability of tuberculosis to human beings from tuberculous animals, either through the medium of milk or the use of their flesh for human food, and numerous investigations have been in progress with a view to establishing the facts relating to this important subject. So eminent an authority as Prof. Robert Koch, who first discovered the primary cause of tuber- culosis, and who first presented tuberculin to the world, while ac- companying the announcement of the latter triumph with the statement that he considered the disease identical in both man and cattle (which view was almost universally accepted by scientists as well as the general public), subsequently announced in 1901 that he regarded the disease as different in man and in cattle, and that there was no practicable need for prohibiting the use of the products of tuberculous animals for human food. This latter statement gave THE MILK SITUATION- IN THE DISTRICT OP COLUMBIA. 73 rise to numerous endeavors on the part of scientific men to establish the truth or fallacy of the position newly assumed by this eminent authority. The results obtained by governmental commissions in different countries, as well as by many public and private scientists, have been so strikingly in accord, in controverting the position taken by Prof. Koch, that it is now the generally accepted opinion among savants that the disease is communicable from beast to man, espe- cially in the case of children. To what extent such infection occurs it is not possible from the nature of things to definitely ascertain, but evidence which must be considered as conclusive has been ob- tained by the Bureau of Animal Industrj^, as well as by Ravenel and a number of French investigators, showing that the percentage of cases indicatkig the transmission of the disease is probably consider- ably greater than claimed by the authorities who have estimated the relative amount of infection from these sources. As vital sta- tistics demonstrate that 11 out of every 100 persons who die suc- cumb to tuberculosis of one form or another, while of the remaining 89 more than one-half show tubercular lesions on post-mortem examination, the value of imposing every reasonable protection against infection may readily be appreciated. Since objective experi- ments on living human beings are not practicable, the finding of the bovine type of tubercle bacillus in human lesions is the most direct and positive proof that tuberculous cattle are responsible for a certain amount of tuberculosis in the human family. In a series of tests conducted by the British Royal Commission on Tuberculosis, 60 cases of the disease among human beings were tested, with the result that 14 cases were regarded by the commission as having been infected from bovine sources. Dr. William H. Park, of New York City, a recognized authority in this country on the diagnosis and treatment of tuberculosis, has recently found 6 cases of bovine infection in 35 samples of in- testinal tuberculosis among infants, and 10 cases due to the bovine type of bacillus out of 35 cases of surgical tuberculosis, representing altogether about 23 per cent of the cases in children due to bovine infection. Of 306 cases reported by Ravenel, 63, or approximately 20 per cent, were found to be due to the bovine tubercle bacillus. Dr. Schroeder, in his interesting article on The Unsuspected But Dangerously Tuberculous Cow, issued December 21, 1907,^ sets forth the dangers of infection from contaminated milk in a manner which the committee deems worthy of repetition. He says (on p. 16) : If the public were thoroughly informed of the dangers, amojig which tuber- culosis is only one of many, to which it is exposed through the use of impure, dirty, and infected milk, the demand for milk of approved purity would rise to the magnitude of a concerted national movement and would sweep all ob- jections and difficulties out of its way. Inform a man that a single one among many loaves of bread — you do not know which — is contaminated with arsenic, strychnine, or some other commonly dreaded poison, and he will go very hungry before he risks eating any loaf of the lot. He knows what arsenic and strychnine are and what he must expect from their introduction into his stomach. Yet he continues to use milk and dairy products and permits his family to use them without first testing their purity or insisting that the doubt about their purity be removed, notwithstanding that they have repeatedly been shown to contain poisons fully as objectionable and potent as those above named, such as the germs of tuberculosis, typhoid fever, scarlet fever, diphtheria, and 1 Circular No. 118, Bureau of Animal Industry, U. S. Department of Agriculture. 74 THE MILK SITUATION IN THE DISTKTCT OF COLUMBIA. other diseases, and the poisons that are the cause of the high death rate from abdominal diseases among children who have not passed the milk-drinking period of life. There is an important moral side to the milk question which must not be ignored. We may have the right— a very doubtful right, to be exact— to neglect the dangers to which we as adults capable of judging and acting for ourselves are exposed, but we have absolutely no right to neglect the conditions that cause suffering and death among children. The failure to act and to act quickly and unceasingly until a safe milk for children at least is within easy reach of every mother may be characterized as barbarous, if not criminal, indifference. Schroeder and Cotton, in a recent bulletin of the Bureau of Ani- mal Industry, set forth that there is no more active agent than a tuberculous cow for the increase of tuberculosis among animals and its persistence among man. When it is reasonably estimated that human tuberculosis causes over 160,000 deaths a year in the United States, the importance of introducing every possible safeguard against the extension of the white plague may well be appreciated. It is gratifying to note that the work of Schroeder and Cotton at the Betliesda Experiment Station of the Bureau of Animal Industry was considered sufficiently significant by the British Tuberculosis Commission to make it the subject of a special investigation and a separate report, the work of the commission fully confirming the results obtained by our investigators. It is unfortunate that the commission should have failed to expressly acknowledge the credit due to these officials of the Government for the important discovery that apparently healthy tuberculous cattle frequently expel large numbers of virulent tubercle bacilli through the rectum with the feces. The International Tuberculosis Congress held at Washington, D. C, in September, 1908, resolved — That preventive measures be continued against bovine tuberculosis and that the propagation of this infection to man be recognized. In a comprehensive investigation by Dr. William H. Park and his associates as to the sources of tubercular infection 7.22 per cent of the patients examined proved on post-mortem examination to be in- fected with bovine tubercle bacilli, 26 per cent of those under 5 years of age showing infection from bovine sources. Dr. Theobald Smith, a leading authority on the subject, found that 10 per cent additional were conclusively demonstrated to be in- fected with bacilli of bovine origin, thus demonstrating that about 17 or 18 per cent of all cases of tuberculosis which were the subject of these investigations were traceable to bovine sources. This work has been largely clone since 1908, and the concensus of opinion among scientific men has since strongly developed in favor of accepting the view that tuberculosis is directly transmissible from cattle to man. Dr. William C. Welch, of Johns Hopkins University, corroborates the statement (based on his observations) that bovine tuberculosis causes from 15 to 25 per cent of certain cases of tuberculosis in children under 5 years of age. In a paper by Dr. Park, director of the research laboratory of the health department of New York, presented as recently as May 3, 1910, before the National Association for the Study and Prevention of Tuberculosis, it was stated that 22 out of 84 cases of tuberculosis in THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 75 children under 5 years of age coming under his observation clearly manifested the bovine type of tubercle bacilli, and bore convincing evidence of the communicability of bovine tuberculosis to man. In a later recent investigation by Park and Krumwiede in the research laboratory of the department of health, New York City,^ the actual number of cases examined was 436, the largest number included so far in a single investigation. Two hundred and ninety-seven related to persons over 16 years of age (278 being pulmonary), only 1 of which indicated bacilli of the bovine type, but in 54 cases of children between 5 and 16 years 9 exhibited bacilli of the bovine type. In 84 cases under 5 years of age 22 individuals were infected with bovine bacilli. In a total of 1,040 cases of human tuberculosis studied and recorded in literature from which pure cultures of tubercle bacilli have been obtained and identified Park and Krumwiede place 686 of these cases in the group comprising patients of 16 years and over, and 9 of these patients exhibited bacilli of the bovine type ; 132 cases in the group of patients between 5 and 16 years old showed 33 to be infected with bovine bacilli, while in the group including chil- dren under 5 years of age, comprising 120 cases, 59 (or admost 50 per cent) proved to be of the bovine bacillary type. The larger propor- tion of the cases showing the bovine type of bacilli consisted of infec- tions of the abdomen and of the glands of the neck, while in not a single case of pulmonary tuberculosis have bacilli of undoubted bovine origin been found.- It has further been demonstrated with scientific exactitude that bovine tubercle bacilli are of a most virulent type and when ingested by human beings with cow's milk continue their virulence in the human body. BRITISH TTJBEKCULOSIS ORDER OF 1909. Confirmatory of the position taken by the American authorities as to the infection of human beings with tuberculosis from bovine sources is the action of the Board of Agriculture and Fisheries of Great Britain in issuing, under date of May 27, 1909. the Tuber- culosis order of 1909, setting forth that — So far as regards the possibility of the transmission of the disease from affected bovine animals to man, the board are satisfied that it must now be accepted as a fact that tuberculosis is transmissible by the agency of milk used for human consumption. The board proceeds further to state that — Any action which results in 'the reduction in the number of tuberculous bovine animals in the country must reduce the risk of the spread of tuber- culosis amongst the community, and if it were possible to eradicate from this country [Great Britain] the disease in animals, a material step forward would have been talcen in the campaign against the disease in man. RESULTS OF INVESTIGATIONS BY GERMAN AND BRITISH COMMISSIONS. In a series of tests conducted by the German commission on tuber- culosis, over 10 per cent of the cultures of tubercle bacilli of human origin were found to be virulent for cattle, and in a similar investi- ^ Park, W.

It may be stated with scientific accuracy^ as the result of the splendid work of American investigators, corroborated by the re- searches of the British and German Government commissions and independent investigators, that bovine tubercle bacilli are fairly common in human beings, the frequent occurrence of bovine tuber- culosis among children of itself emphasizing the importance of elimi- nating by the tuberculin test cattle proved to be infected with tuber- cular lesions, and insisting upon pasteurization before their product is offered for sale. RESOLUTIONS BY NATIONAL AND LOCAL ASSOCIATIONS FOR STUDY AND PREVENTION OF TLTSERCULOSIS. At a recent meeting of the National Association for the Study and Prevention of Tuberculosis, held in Washington in April, 1910, resolutions were adopted (Appendix AD) urging the efficient supervision of dairy herds and of the handling of milk from the dairy to the consumer, and emphasizing the importance of a clean and pure milk supply as essential to the public health. The reso- lutions conclude with a feeble indorsement of the position that, in a certain percentage of cases, human tuberculosis is due to infection by tubercle bacilli of bovine origin. At a meeting of the board of directors of the local association for the prevention of tuberculosis, held December 27, 1910, resolu- tions offered by Dr. George M. Kober and seconded by Mr. Emile Berliner and Dr. G. Lloyd Magruder, were unanimously adopted (Appendix AE) reciting that, whereas it has been shown by indis- putable evidence that numerous epidemics of typhoid fever and other diseases have been traced to contaminated dairy products, that a considerable proportion of the cases of tuberculosis occurring in children under 5 years of age is the result of infection with the bovine tubercular bacillus, and that the mortality among infants fed upon cow's milk is very high, the Congress of the United States be requested to investigate the relation of dairy products to the public health, with a view to the enactment of remedial legislation. BACILLI INTRODUCED INTO HUMAN BODY DURING INFANCY. A potent factor in support of the belief that tuberculosis is di- rectly communicable from cattle to man is the discovery in recent years by bacteriologists of certain interrelated species of tubercle bacilli showing apparent transition from the bovine to the human types of tubercle bacilli and vice versa. It has furthermore been established with apparent rationality that the bacilli may be introduced into the human body during infancy and remain dormant until some later period in life when they are aroused to activity and develop malig- nant tuberculosis, their activity remaining latent, in some instances, or being arrested until the person arrives at the age of three score or more. THE MILK SITUATION IN" THE DISTRICT OP COLUMBIA. 77 Dr. Schroeder observes in this connection that by far the largest percentage of cases of human tuberculosis results from the ingestion of tubercle bacilli during the first five years of infant life, during which period the food of the child is restricted exclusively to a milk diet, and that the bacilli develop destructive virulence and energy often during the " high school " period of education, when the worry and mental strain of the child has reduced it to a condition of health which makes it impossible to combat the attacks of the germs ; and in other cases at the age of approximately 25 years, when the worry and anxiety which may be regarded as the natural accompaniment of the initiation seriously into one's life work may be supposed to induce inability to cope with the development of disease germs; and then, again, in certain instances, about the age of 45, when those who are failures in life's battle begin to realize the hopelessness of their further endeavors toward success. It is significant that, at these periods of life, tuberculosis succeeds most effectively in its deadly ravages. EFFICACY OF TUBERCULIN TEST IN ERADICATING HUMAN TUBERCULOSIS FROM BOVINE SOURCES. A number of authorities consulted by the committee unite in the opinion that the tuberculin test, if generally applied in a given juris- diction, will completely eradicate the disease from bovine animals, and will remove entirely the possibility of human infection with bovine tubercle bacilli. Freeman is authority for the statement that a third of the cases of human tuberculosis in persons under 15 years of age would probably be eliminated. Winslow predicts that human tuberculous infection from milk can be largely controlled by the tuberculin test. Dr. Babb, dairy and milk inspector of Topeka, Kans., expresses the belief that most human pulmonary tuberculosis is gained from the use of milk from tuberculous cows, and that the transmission of the disease from this source would be very greatly diminished by the enforcement of the tuberculin test in a rational, systematic manner. Dr. Coit is convinced that the enforcement of the tuberculin test will curtail human infection with bovine tubercle bacilli only to the extent that tuberculosis is now disseminated by market milk. It will, in his opinion, reduce by 25 per cent the number of cases of tubercu- losis occurring in children. RECOMMENDATIONS BY DR. JOHN R. MOHLER. With a view to insuring against the prevalence of tuberculosis through infection from bovine sources, the following recommenda- tions are proposed by Dr. John E. Mohler, Chief of the Pathological Division of the Bureau of Animal Industry, Department of Agricul- ture, in a paper entitled " The Importance of a Wholesome Milk Supply " : ^ 1. That all cows on dairy farms producing milk for market purposes be tagged, tattooed, or otherwise marked for identification. ^ The Dissemination of Diseases by Dairy Products and Methods for Prevention, Circu- lar No. 153, Bureau of Animal Industry, U. S. Department of Agriculture, p. 37, issued Apr., 28, 1910. These recommendations by Dr. Mohler were previously published in almost identical phraseology in Bulletin No. 56, Hygienic Laboratory, Public Health and Marine-Hospital Service, pp. 525, 526, issued in March, 1909. 78 THE MILK SITUATION IN THE DISTEICT OF COLUMBIA. 2. That all milk produced on such dairy farms shall either come from tuber- culin-tested cattle, which shall be retested at least once a year, or be subjected to pasteurization under the supervision of the health authorities in case the herd is not tuberculin tested. 3. That no additions to any herd, whether the herd has been tested or not, shall be made in the future without subjecting the additional cattle to the tuber- culin test. 4. That no license for the sale of milk shall in future be granted except to applicants having herds free of tuberculosis. 5. That the milk of cattle showing any of the udder affections above men- tioned,^ or anthrax, rabies, gastroenteritis, septic conditions, or clinical symp- toms of tuberculosis, shall not be utilized as human food, even though the milk be pasteurized. Milk from cows 15 days before and 5 days after parturition shall likewise be excluded. 6. That veterinary inspectors of the health department make frequent visits to daries having untested herds, in order that they may discover all advanced cases of tuberculosis or udder tuberculosis as early as possible. 7. That the various States pass laws granting an appropriate indemnity to all owners of tuberculous cattle which come under their respective jurisidctions, the said animals to be slaughtered in abattoirs having Federal or other efficient inspection. MILK USED IN DAIRY PRODUCTS SHOULD BE TUBERCULIN TESTED. Numerous investigations by recognized authorities, both in Europe and in this country, have conclusively demonstrated that tubercle bacilli may be present in butter, buttermilk, oleomargarine, and cheese, and that butter made in the customary manner and stored under ordinary market conditions until time of sale may retain virulent bacilli for several months. It is of essential importance, therefore, that the restrictions and safeguards applied to milk and cream should be extended to the various milk products so far as nec- essary to protect the public from the dangers of infection from these sources. The requirement that all dairy herds be subjected to the tuberculin test, and in addition to this that the milk from such herds should be pasteurized before it is used, should apply not only to milk and cream used in their raw state, but likewise to all milk and cream contained in ice cream, buttermilk, butter, and cheese. ECONOMIC CONSIDERATIONS AFFECTING BOVINE TUBERCULOSIS. Aside from the imminent danger of communicating this dreaded scourge to humanity, there is an economic consideration of great importance to the farmers of our country in eradicating tuberculosis from their herds. It is believed on good authority that between 15 and 25 per cent of all the cows supplying milk to the District of Co- lumbia are tuberculous. It may be recounted that, during the period from April, 1907, to June, 1909, inclusive, the Bureau of Animal Industry supervised the testing of 2,471 cattle in herds supplying milk to the District, Avith the result that 377, or 15.25 per cent, were shown to be tuberculous. Nor is this startling percentage a f^ir esti- mate of the extent of tuberculosis among the dairy herds of this vi- cinity, since the number of animals tested includes many herds which had either been examined previously or which had exhibited such a healthy appearance as to remove any suspicions of tuberculosis. 1 Tuberculosis of tbe udder, botrj-omycosis, mammitis, mastitis, etc. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 79 _ Statistics show that where the tuberculin test has been established either compulsorily or voluntarily on the part of cattle owners, tuberculosis is gradually being eradicated, while in localities where the tuberculin test has not been applied, the disease is spreading rapidly and becoming widely disseminated, the cattle owner being confronted with serious and continuous losses. Tuberculin may, therefore^ be considered a most beneficial agent to the stock raiser. As an indication of the extent of the movement for the elimination of tuberculosis among farm animals, it may be stated that 41 States (Appendix AF) at present require the application of the tuberculin test to cattle brought within their boundaries, this requirement usually being limited, however, to cattle for dairy or breeding pur- poses; and that 21 States and the District of Columbia (Appendix AG) provide for the slaughter of animals found to be affected with tuberculosis, and for the payment of an indemnity to owners; while a few others give authority for condemnation and slaughter without making provision for indemnity. Twenty States and the District of Columbia (Appendix AH) provide for the tuberculin testing of cattle within the State (not necessarily the subject of interstate com- merce). USE OF MEAT OF CONDEMNED ANIMALS FOR FOOD. It is adduced that it is inconsistent on the part of the Federal au- thorities to permit the use for food of the meat of animals condemned on account of tuberculosis, while at the same time proposing to pre- clude the use of milk derived from such animals. The committee is reliably informed by officials of the Bureau of Animal Industry that animals may be infected with tuberculosis in certain parts of the body, this local infection not permeating the muscular portions or other parts of the animal utilized for food purposes. The Depart- ment of Agriculture has consequently, in the execution of the meat- inspection law, very properly permitted, under rigid inspection, the utilization of such parts of carcasses as are definitely and absolutely known to be free from contamination with tubercle bacilli. The question raised as to the propriety of slaughtering for con- sumption animals having localized diseases has been the subject of careful and protracted deliberation by the Bureau of Animal In- dustry in enforcing the Federal meat inspection regulations, for- mulated and promulgated in pursuance of the act of Congress ap- proved June 30, 1906.^ It was suggested from several sources that, in order to enlist the public support and cooperation of packers which is so manifest in the execution of meat-inspection rules in European countries, the regulations adopted by the Department of Agriculture for controlling the meat industry in the United States should be submitted for criticism to a commission of experts not connected with the department, whose findings as to the effects of disease upon meat with reference to its fitness for human food would command the confidence of the packers and dealers as well as of the public generally. In pursuance of this suggestion, a commission was des- ignated by the Secretary of Agriculture, composed of men whose 1 Provisions for Federal meat inspection incorporated in Agricultural appropriation act lor 1907, approved June 30, 1906. 80 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. eminence as authorities on the subject in question was generally con- ceded, and this commission, after thorough discussion and conference, reported its conclusions. The findings constituted in the main a con- firmation of the wisdom of the regulations then in force, certain minor emendations being suggested by the commission, which have been approved by the department and incorporated in the rules for the disposition of meats now in operation. As felicitously expressed by Dr. Melvin at the preliminary meet- ing of the commission, the department is required by law to stand as the mediator between the slaughterers and the consumers, and its only thought is to do justice to both. It may be observed, he ex- plained, that if there was any error in Regulation No. 15 safeguard- ing the public health, this was in favor of the public rather than in favor of the butchers and packers, and that the requirements of the department with reference to the condemnation of diseased animals could be made less stringent without danger to the health of the consumer. It frequently happens that an animal is infected with a localized disease which may not impair to the slightest degree the nutritive or food value of the parts of the carcass which are customarily eaten in a community, and while it is evident that, from an economic stand- point, it would be decidedly improper and wasteful to an extreme degree to condemn as a whole carcasses affected in certain organs only, your committee is convinced that the regulations of the depart- ment impose every reasonable safeguard for the protection of the health of the public against possible infection fiom diseased meat. It should be observed, however, on the other hand, that milk (con- sisting as it does of secretions from the mammary glands) from any cow afflicted with almost any disease, however localized, is fraught with danger of contamination, intermittently at least, by death-dealing germs. The committee feels, therefore, that the sepa- ration of a diseased animal from a herd of milch cows is justifiable in every instance, while the use of portions of the carcass of the same animal, when slaughtered, may be advocated as entirely unprejudicial to the health of the consumer. Any attempt, therefore, to condemn for food purposes cattle in the wholesale manner suggested in some quarters would doubtless effect an absolute scarcity of the meat supply, resulting in high prices for beef, veal, and other products of the cow and calf, and serving to place them entirely beyond the reach of the purchaser of moderate means. Aside from the generally recognized importance of eradicating tuberculosis from among cattle on account of the contamination of the milk supjoly derived from infected animals, and while assenting to the proposition that the saving of human life affords the highest motive for combating tuberculosis among animals, the economic im- portance of its elimination with the object of relieving the tremen- dous financial loss at present devolving from this cause upon the live-stock industry of the country should not be overlooked. This phase of the question is treated in a most convincing and capable manner in a paper entitled " The Economic Importance of Tuber- culosis in Food-Producing Animals," by Dr. A. D. Melvin, Chief of the Bureau of Animal Industry,^ read before the International Con- 1 Twenty-fifth Annual Report of the Bureau of Animal Industry, U. S. Department of Agriculture, 1908, THE MILK SITUATIOlSr IN" THE DISTRICT OF COLUMBIA. 81 gress on Tuberculosis in Washington on September 29, 1908. Dr. Melvin observes that, while it must be realized that the exclusion of tuberculous meat and dairy products from the food supply means an appreciable reduction in the quantity of available food, with a corresjDonding tendency to an increase in the cost of such commodi- ties, no nation is so wealthy that it can afford to sacrifice year after year a considerable and increasing proportion of its food supply, especially when by proper means the loss can be reduced and in time entirely prevented. The animals principally infected with tuberculosis, he states, are cattle and hogs, the disease being easily communicated from the former to the latter by the common practice of giving skim milk to the hogs and allowing them to feed on the excrement of the cattle. Wlien we consider, in addition to the loss occasioned by the necessity of slaughtering cattle and hogs, the considerable depreciation in the value of these animals when affected with the disease, if remaining alive, as also the effect of decreasing the productiveness of dairy cows by diminishing the yield of milk, as well as by shortening their lives, and consequently the period during which they produce milk; and when we realize, furthermore, that there are doubtless other sources of loss chargeable to this disease in live stock, it is conservatively estimated by Dr. Melvin that the tribute which the United States pays each year to this scourge among its farm animals aggregates more than $23,000,000. Consider in addition to this enormous ex- action the bearing of animal tuberculosis on human life, and it seems imperative that vigorous measures should be promptly adopted to eradicate the disease from our herds. The work of the Federal Government, as carried on by the Bureau of Animal Industry, has thus for been exerted in this connection in supplying tuberculin free of charge to State officials, in endeavoring to prevent the interstate shipment of tuberculous animals, and in tracing, when practicable, the origin of animals found to be affected with tuberculosis. It has been contended that the rigid enforcement of the tuberculin test and the condemnation of unhealthy cattle will produce a tem- porary, if not a permanent, shortage in the local milk supply. This condition, should it become apparent, will, it is believed by the com- mittee, be readily met by resorting to pasteurization to render in- nocuous the milk derived from affected cattle and by authorizing the delivery and consumption of milk so treated from cattle which have not withstood the tuberculin test until such time as may reasonably be required to replace with healthy cattle animals found to be dis- eased. . While the committee places itself on record as unqualifiedly favor- ing the application of the tuberculin test, it is especially recommended that the test be gradually applied; that is to say, that a reasonable amount of time be reserved before the test shall be rigorously exacted, and that the herds supplying milk to the District be inspected seri- atim, with such gradualness as may be intelligently calculated to enable the replenishment of the herds by the replacement of such animals as may be eliminated by operation of the test. The District Commissioners have, upon the recommendation of Dr. Woodward, 82444 °~S. Doc. 863, 61-3 6 82 THE MILK SITUATION IN THE DISTEICT OF COLUMBIA. health officer, wisely consented to the postponement of insistence com- pulsorily upon the test in the case of all herds located in Maryland, Virginia, and elsewhere outside of the District of Columbia, fur- nishing milk for consumption in the District, for such period of time as the farmers may reasonably require to prejoare themselves to meet the conditions of the test and until the legislatures of the States of Maryland and Virginia may have an opportunity to provide adequate compensation for animals condemned. It is proposed by the com- mittee that a period of two years might appropriately and advan- tageously be arbitrarily fixed for the introduction of the test compul- sorily among herds supplying milk for consumption in the District. The committee concludes its observations on this feature of its investigations with the remark that the tuberculin test has been found to be a more nearly infallible means for diagnosing tuberculosis than any known agency for diagnosing other diseases of men and animals ; and since it is the consensus of scientific thought that our dairy herds can be freed from tuberculous cows by the systematic application of the test and the segregation of aM reacting animals, the committee recommends without hesitancy that the compulsory application of the test to all animals furnishing milk to the District of Columbia be required as rapidly as the exigencies of the situation will allow. VI. Maintenance of Low Temperature. ESSENTIALITY OF TEMPERATURE NOT EXCEEDING 50° F. Since the bacterial content of milk depends, (1) upon its age, (2) the number of bacteria contained initially and proliferated, or in- troduced during the process of milking and handling, and (3) the temperature at which the milk is kept, cleanly milk, quick cooling, and the shortest practicable time between milking and consumption are important factors in providing a pure milk supply. Not only should the milk be cooled immediately, which has been proved be- yond peradventure to be an exceedingly important requirement, but in order to prevent the rapid multiplication of germ life, it should be kept cool until consumed. This necessitates the maintenance of low temperature in hauling to the depot, while waiting at the ship- ping point, during transportation on the cars, and while being held and distributed by the city dealer. In the winter months, the low atmospheric temperature renders the keeping of milk below 50° F. easy of accomplishment, but in the warm season to maintain the desired temperature involves the use of efficient methods of refrigera- tion on the part of the dairyman, the transportation company, the wholesale distributer, the retail dealer, and, finally, on the part of the consumer. The rapid cooling of milk after it has been drawn, to a temperature of 45° F., and the maintenance of that temperature until the time of consumption, not only prevents the multiplication of the bacterial flora contained in the milk when drawn from the cow, but actually tends to diminish the number of bacteria. So eminent an authority as Dr. William H. Park, of New York City, gives testimony to the effect that milk rapidly and sufficiently cooled remains almost unaltered chemically and bacteriologically for THE MILK SITUATION" IN THE DISTRICT OF COLUMBIA. 83 36 hours, while milk that is insufficiently cooled (that is to say, allowed to attain a temperature in excess of 45° to 50° F.) deteriorates rapidly. Dr. Park states later that while 45° F. is a desirable stand- ard, 50° F. is, in his judgment, much easier to observe and will answer fairly well. He assigns the failure to keep milk below the tempera- ture of 50° F. as the greatest reason for the deterioration of city milk. Dr. Coit asserts that, according to a well-known expert, a quart of milk maintained at 60° F. in a refrigerator will grow 19,000,000 germs in 24 hours. The rapidity with which bacteria multiply at a temperature some- what slightly above 50° F. has been well illustrated by a recognized authority on the subject, who, in an experiment with milk containing 153,000 organisms per cubic centimeter when exposed to a tempera- ture of 59° F., showed a proliferation to more than treble this number in a single hour, the milk attaining the almost incredible figure of 85,000,000 bacteria per cubic centimeter at the end of 24 hours. When it is realized that a cubic centimeter corresponds approximately to one-fourth of a teaspoonful, the enormity of this increase in a given sample of milk can easily be imagined. A series of systematic investigations has shown that the tempera- ture, in order to retard generation of germ life, should be maintained as low, at least, as 50° F. Pathogenic or disease-breeding organisms are shown to multiply with remarkable rapidity when milk is main- tained at temperatures ranging from 50° to 60° F., and even more markedly when 65° F. is reached. Although the practical observance of this requirement means the establishment of icehouses on dairy farms for the storage of a sufficient supply to maintain this reduced temperature from April 1 or earlier to November 1, or later in excep- tional instances of mild weather, and the installation of refrigerator cars or the jacketing of cans in an efficient manner to keep down the temperature, which requirement, if insisted upon, mTist necessarily add to the cost of cooling, transporting, and delivering the local milk supply, your committee is nevertheless, after careful consideration, convinced that the arrangement is necessary in the interest of the public health and should be made effective by suitable legislation, provided that, so far as transportation is concerned, it be determined, upon examination of figures in detail, that refrigerator-car service is an economic possibility. The requirement should, moreover, extend to the refrigeration of the milk while on delivery wagons, so as to continue the reduced temperature at a maximum of 50° F. until actual delivery at the residence or place of occupation of the consumer. Dr. Park entertains the view that it is practicable to maintain a temperature not exceeding 50° F. on delivery wagons, provided the cans be protected from exposure to the air by boards or canvas and a little ice be kept on the cans. The committee appends (Appendix AI) in this connection copy of a letter addressed, under date of October 9, 1907, by Surg. Gen. George M. Sternberg, United States Army, retired, to Dr. G. Lloyd Magruder, of this city, giving testimony as to the practicability of shipping milk in cans reenforced with a felt jacket for very consider- able distances without attaining a maximum of 50° F, 84 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. The reasonableness of exacting a temperature that shall not exceed 50° F. is confirmed by the practice in such advanced communities as New York and Boston, the regulations of each of which cities specify a maximum temperature of 50° F., while Chicago enjoins a tempera- ture of 45° F. or less. The committee has weighed with the utmost care and deliberation the probable effect of compulsorily maintaining a temperature of 50° F. or less from the time of milking to the actual moment of delivery to the consumer, for it is recognized that the initiation of such a requirement will necessarily compel every dairyman to install on his farm a suitable icehouse, with facilities for carrying a suffi- cient store of ice to maintain the milk below the prescribed maximum temperature during the season from April 1 to December 1 of each year. If this proposal were merely the result of a theoretical step toward the improvement of the milk supply, the committee would have more hesitancy in coming to a conclusion in the matter, but it is so clearly convinced that pathogenic bacteria proliferate with as- tounding rapidity when milk is allowed to attain a temperature of even 2 or 3 degrees in excess of 50° F. that it is indispensably neces- sary, in its judgment, in the interest of the public health, that this requirement be gradually put into force, notwithstanding its material bearing as respects increased outlay on the part of the producer, and with the fullest consciousness of the great benefit which will inure from the enforcement of this perhaps seemingly onerous exaction. The requirement that milk be kept at a temperature below 50° F. should likewise be rigorously enforced with reference to hotels, lunch rooms, cafes, and other public places where milk is consumed as a beverage in its raw or pasteurized state. It has been claimed that, owing to the germicidal qualities of raw milk, the number of bacteria is reduced when kept under certain con- ditions of temperature free from contamination, which contention is advocated in defense of raw milk as opposed to pasteurized milk. Dr. Park, who studied this question in 1901, concluded that freshly drawn milk contains a slight and variable amount of chemical substances which are capable of inhibiting bacterial growth, and that at tern-' peratures under 50° F. these substances act efficiently for from 12 to 24 hours, provided the milk be not filthy, but that at higher tempera- tures the inhibiting effect of these chemical substances is very soon completely negatived and the bacteria in milk maintained at such temperatures will then rapidly increase. Thus the bacteria in fresh milk which originally proved 5,000 per cubic centimeter, decreased to 2,400 in the portion kept at 42° F. for 24 hours, but raised to 7,000 in that kept at 50° F., to 280,000 in that kept at 65° F., and to 12,500,000,000 in that portion kept at 95° F. This intelligent deduc- tion emphasizes the extreme importance of keeping milk at tempera- tures below 50° F. NECESSITY FOR ADEQUATE REFRIGERATOR-CAR SERVICE. With regard to the objection raised by the producers and dealers to the proposal that all milk supplied to the District of Cohnnbia be required to be maintained at a temperature not exceeding 50° F. from the time of milking until the actual delivery to the consumer, THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 85 the committee feels that this requirement is impossible of practical observance without the installation of an adequate number of re- frigerator cars or the provision of a practical and efficient can jacket. The committee has had great difficulty in securing from the rail- ways entering Washington any definite information which would lead to a proper conclusion as to the practicability of providing the necessary refrigerator-car service or some alternative means for maintaining milk during transportation at a temperature below 50° F. The Pennsylvania and Southern Railways, and the New York Central & Hudson River Railroad Co. were the only ones to heed the request of the committee. President Brown, of the New York Central lines, regrets that it is impossible to furnish compara- tive figures, for the reason that the cost of refrigeration varies on different parts of his lines, being governed, he says, by weather con- ditions, the kind of container in which the product is shipped, the length of haul, facilities for rapid handling at destination, etc. The conditions in the District of Columbia are, furthermore, he maintains, different from those in New York State. Mr. J. R. Wood, passenger traffic manager of the Pennsylvania Railroad Co., has, through reference from President McCrea, fur- nished the committee with certain data relating to the subject of its inquiry. He explains that three factors enter into the cost of haul- ing milk under refrigeration, namely, the length of the haul, the temperature of the milk when placed in the car, and the circumstance whether the cars are to be loaded ali at one point or at intervals between originating point and destination. If the class " Rf " refrigerator car is to be used for the purpose proposed, the initial icing would, he estimates, require 7,400 pounds. After precooling, 4,000 pounds would be sufficient to maintain the milk under a tem- perature of 50° F. for a distance of 300 miles; that is to say, a 24-hour run. If, however, the car is to be opened at different points to receive milk, the temperature will fluctuate according to outside conditions. The cost for icing a car with 12,000 pounds of ice will approximate $15 (that is on a basis of $2.50 per ton of ice, including necessary labor). By using the same cars m this milk service, the bunkers would retain a percentage of the ice from one trip until the next, and the car would thus require on the same basis as above an average of only about 3,000 pounds of ice at a cost of $4. The cost per gallon for refrigerated milk will depend on the number of gal- lons loaded in a car. The length of the haul, he states, would make no material difference in the cost of refrigeration, due to the fact that the requisite amount of ice and the necessary space for loading would need to be provided from the starting point of the car to the places of receiving and discharging its load. It is interesting in this connection to note the present cost per gallon of milk shipped over the Pennsylvania lines from varying distances to Washington, namely, less than 30 miles, 1| cents per gallon ; between 30 and 60 miles, 2 cents per gallon ; over 60 and not exceeding 90 miles, 2^ cents per gallon. Double rates are charged for the shipment of cream. It is contended by the officials of the railways transporting milk into Washington that the length of the hauls and the aggregate amount of shipments do not justify the expense of providing and maintaining the necessary number of refrigerator cars for this serv- 86 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. ice unless such increase in the rates of transportation be exacted as would make the retail price of milk to the consumer prohibitively high. The committee appends copies of correspondence with the New York Central and the Pennsylvania Railways relating to this phase of its investigations (Appendix D). Officials of the Southern Railway have informally assured the committee of their desire to do everything possible to further the committee's recommendations, but they feel that it is absolutely impossible, without the imposition of prohibitive traffic rates, to maintain the necessary service. Milk is at present hauled over the several branches of the Southern Rail- way at a flat rate of 2^ cents per gallon, which includes the return of the can or other receptacle to the shipper. FEASIBILITY OF PROVIDING ADEQUATE SUPPLY OF ICE. Aside from the conditions affecting the feasibility of introducing an appropriate service of refrigerator cars, it is contended by the producers of milk that it is not practicable without a decided advance in the price of milk received by the shipper to install and equip the necessary ice houses for maintaining the low temperature from the time of milking to the instant of actual delivery on board the train. An examination of bulletins furnished through the courtesy of Prof. Willis L. Moore, Chief of the United States Weather Bureau, shows that it has been possible, with the exception of one winter, during the past 30 years to collect from ponds, natural or artificially pro- vided for this purpose, an abundant supply of ice 4 inches or more in thickness, to enable the farmer to lay up a sufficient store to meet this requirement of refrigeration from April 1 to December 1, the interval during which in this latitude it is necessary to provide arti- ficial means of maintaining a maximum temperature of 50° F. This deduction is confirmatory of a letter on the same subject from the Chief of the Weather JBureau under date of December 29, 1906 (Appendix AJ). It is claimed by local wholesale and retail dealers, furthermore, that the insistence upon this requirement will have the effect of driv- ing all of the small dealers out of business, as they allege that the ■public is neither willing nor able to pay the increased price which must necessarily be established in order to meet this proposed restric- tion. So much for the mercantile side of the question. As to its scien- tific aspects, it is a matter of general agreement among authorities on the subject of milk production and distribution that, although milk obtained from the cow under the most careful conditions contains a minimum number of bacteria, these bacteria multiply with alarming rapidity when milk is subjected to temperatures in excess of 50° F., and this observation applies with equal force to pasteurized and to raw milk. The failure to keep milk at a temperature below 50° F. provides favorable conditions for rapid multiplication of bacteria. Milk is a good culture medium for various pathogenic organisms which rapidly increase in high temperatures, making such milk dangerous, espe- cially for infants. Dr. Wyman, Surgeon General of the Public Health and Marine-Hospital Service, asserts that if milk happens to contain a small number of typhoid bacilli or other organisms a great THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 87 increase in these organisms will take place if the milk be not kept below 50° F. The moment that a higher temperature than 50° F. is approached the proliferation of deleterious as well as other germs increases with astounding celerity, it being demonstrated by reliable authorities, as already stated, that a temperature of even 52° to 55° F., for example, encourages a much more rapid development of bac- teria than 50° F. Some authorities suggest specifying as low as 45° F., but there is a substantial agreement among those qualified to speak in favor of 50° F. as a maximum temperature for maintaining milk from the time of milking till delivery to the consumer. Dr. Melvin, Chief of the Bureau of Animal Industry, observes in this connection that the specification of that temperature would require the use of ice in summer, but that this is not believed to be commercially im- practicable, except j)ossibly during the summer in warm climates, where the producer is unable to provide ice. This requirement, he states, has been met by the city of Atlanta, Ga., and if it is practicable there it should certainly be practicable for the city of Washington. The feasibility of meeting this situation will, it is observed by Surg. Gen. Stokes, depend among other things upon the facilities granted by the railroads and the amount of capital put into the business. Dr. Hamill, of Philadelphia, expresses the view that from 40° to 50° F. is the maximum temperature at which milk should be kept to give the best results when commercially used. He is of the opinion that it is practicable to maintain a maximum temperature of 50° F. from time of milking to city delivery to the consumer, provided the producers, the railroad companies, and the dealers can be compelled by law to adopt proper methods. On the other hand, it is stated by the health officer of Columbus, Ohio, that 50° F. is too low for market milk under ordinary conditions as experienced in Columbus, a 65° F. rule having been in force in that city for two years past. If the temperature could be fixed primarily to satisfy the con- venience and advantage of the producer and dealer, this higher temperature could well be determined upon, but the committee is fully impressed, after consulting the authorities on the subject, that the fixing of 65° F. as the maximum temperature would not accom- plish the end desired, and that this higher temperature would permit of rapid multiplication of disease-breeding germs in milk. If the somewhat low temperature specified be not enforced by stringent regulations of the health authorities, all other precautions (save, perhaps, the tuberculin test) tending to the production of a pure milk supply and the elimination of the danger of infection through contamination of the milk will be negatived to such an extent as to almost totally defeat the purpose of the requirement. The committee is strongly inclined to believe, therefore, that, not- withstanding the claims put forward by the producers and dealers as to the prejudicial effect upon their business and the possibility, if not likelihood, of a considerable shortage in the milk supply, the interests of the public health demand that this requirement be put into effect and rigidly enforced. PRESCRIBED HOURS OF DELIVERY NOT FEASIBLE. The committee has considered, in tliis same connection, the prac- ticability of assuring the maintenance of the prescribed temperature by limiting the hours of delivery, especially at residences, so as to 88 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. avoid the exposure of the milk to the rays of the sun or to warm air when standing on the doorstep. While it is undoubtedly desirable, in the judgment of the officials of the Bureau of Animal Industry, that milk should not be permitted to remain on the doorstep in warm weather long enough to allow a material rise in its temperature, the feasibility of specifying certain hours for its delivery is questioned. Some of the persons consulted by the committee are dubious as to whether such regulations would be capable of enforcement, while others suggest that the milk be so placed as to shelter it from the sun. In the opinion of Dr. Goler, health officer of Kochester, N. Y., milk should not be permitted to be delivered to the consumer prior to 6 o'clock a. m., while Dr. Walter S. Wheeler, health commissioner of Kansas City, Mo., alleges that in some cities regulations prescribe from 12 o'clock midnight to 8 o'clock in the morning as the hours for city delivery. In Wheeling, W. Va., the distributor of certified milk is not al- lowed to leave it on the doorstep, but must place it in an ice chest or in the hands of an adult member of the family. Dr. J. M. Houston, bacteriologist of the Washington branch of the White Cross Milk Co., is decidedly of the opinion that milk should be required to be delivered after 7 a. m., so that it can be taken into the home and not exposed to contamination on the doorstep and to the rays of the hot sun in summer and to freezing in winter. He adds that if this plan be effectuated, the dealer would not be embarrassed so largely by complaints of stolen milk and by the inefficient class of help on which he must depend for earlier deliveries. Dr. Hamill, of Philadelphia, considers it very important to pre- scribe definite hours for the city delivery of milk, the dealer being required to deliver the milk at such hours as to enable the consumer to receive it into his home immediately upon delivery. Dr. Park favors the limitation of hours of city delivery during the warm months, so that milk would not, at least, remain more than 30 minutes exposed to a temperature above 55° F. Dr. J. P. Kennedy, health officer of Atlanta, Ga., thinks that the subject could best be controlled by issuing from the health department printed slips of instructions, to be delivered at intervals by dairymen to their customers. The committee is not prejDared to commend as feasible the speci- fication of certain fixed hours for delivery, since, in its judgment, to exact this requirement would compel a large supplemental outlay on the part of distributors for additional delivery wagons and help, and would possibly make the retail cost of milk prohibitivel}^ high, im- posing a hardship on the milkman and possibly embarrassing the plans of the householder. TEMPERATURE FOR MILK PRODUCTS. The fact that cream is shown to contain pathogenic germs in viru- lent form convinces the committee that it is advisable to require this to be maintained at a temperature below 50° F., and the committee consequently recommends that such a requirement be imjoosed. The same observation does not apply, however, to butter and cheese, which, owing to their density, are not favorable to the proliferation of pathogenic germs at ordinary temperatures, though it should be demanded that milk from which these products are made be kept, up 1H£ Milk situation in the district op Columbia. 89 to the time of their manufacture, at a temperature not in excess of 50° F. There would appear to be no reason for a similar speciJ&ca- tion concerning buttermilk. FREEZING or MILK. The committee has examined with interest a report by United States Consul T. H. Norton (Appendix AK) of an address by Prof. Hempel on the " Treatment of Milk " before the seventy-ninth an- nual meeting- of the German Association of Scientists and Physicians, held at Dresden, Saxony, in September, 1907, discussing the feasi- bility of transporting and delivering milk in a frozen condition. Ex- haustive experiments have shown conclusively, Consul Norton states, that pure milk when frozen preserves its original properties un- changed for weeks. Frozen specimens, kept for over a month in the refrigerating room, showed on thawing absolutely no alteration in taste, while the fact of a considerable diminution in the number of bacteria present was clearly established. Important also, he con- tinues, was the circumstance that while frozen the cream remained evenly diffused throughout the solidified mass, which is not the case when milk is kept at a low temperature in a liquid state. To attain good results, he adds further, it is essential that pure, fresh milk, as soon as collected from the animal, be rapidly cooled to the freezing point. Dirty and contaminated milk, as well as milk in which the lactic fermentation has begun, after being frozen, curdles upon melt- ing. He offers the suggestion that fresh milk could be frozen in the proper containers by submerging them in brine chilled far below the melting point of ice, and that, when the milk has not only been frozen, but cooled still further to the temperature of the surround- ing liquid, the flasks or other containers could be removed, inclosed in felt protectors, and conveyed to the consumer. Frozen milk prepared under such conditions will, he contends, remain in a solid state for a day or more before the temperature of the entire mass can rise to the melting point. He further remarks that refrigerator cars would obviously be unnecessary for the transportation of milk in this form, unless unusually long distances are to be traversed. The compara- tively small, cost of freezing and chilling the jnilk supply of a city would, he asserts, be more than offset by economy in transportation, by the utilization of rem»te and inexpensive pasturage, and by the removal of one of the gi-avest causes of infant mortality. There is considerable diversity of opinion as to the effect produced by freezing on the qualities of milk. Of 24 expressions of opinion on the subject, the committee finds 3 proj)onents of the belief that freezing has no effect whatsoever, while 5 of the authorities consulted maintain that the prejudicial effect is slight, if appreciable at all. Surg. Gen. Stokes claims that freezing has little or no influence, while Surg. Gen. Torney says that the effect is not injurious unless the freezing be long continued, when it would probably diminish the germicidal power of the milk.. According to Dr. Melvin freezing has the effect of separating the butter fat and causing the fat glob- ules to collect into granules. Dr. Duncan, bacteriologist and chief inspector of the health department of Birmingham, Ala., contends that it changes the character of milk slightly, and that it is not always possible to insure a good quality of milk after melting. This 90 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. practice has, he reports, been tried in some parts of Europe " without satisfactory success." Borden's Condensed Milk Co. states that freezing itself has really no effect whatever on the quality of milk, provided the milk in being restored to its normal condition is care- fully mixed. Milk, however, does not, it goes on to state, keep indefi- nitely in a frozen condition, as certain forms of bacteria multiply even in that condition, while the lactic acid bacteria are entirely dormant. Bacteria are not, however, destroyed by freezing, even when the frozen condition extends over a period of time. Dr. Pres- cott observes that frozen milks are sold in Europe and used with apparent impunity. Dr. Wiley, Chief of the Bureau of Chemistry, United States De- partment of Agriculture, states that while he has not made experi- mental determinations on the effect of freezing milk, he is of the opinion that it profoundly modifies its character, perhaps not so much in regard to its potability (that is to say, its quality for drink- ing purposes) , as to its wholesomeness and nutritive qualities. His belief in the matter is, he avers, based on the well-known fact that the freezing of wine or beer, or of meats or fruits, profoundly affects their character, for which reason, in his judgment, milk, especially if intended for the nutrition of infants, should never be frozen. VII. Pasteurization. PASTEURIZATION AND STERILIZATION DEFINED. Pasteurized milk is defined in the Standards of Purity for Food Products,^ issued by the Secretary of Agriculture in pursuance of authority given by Congress in the food and drugs act of June 30, 1906, as follows : Pasteurized milk is milk that has been heated below boiling, but sufficiently to kill most of the active organisms present, and immediately cooled to 50° F. or lower. Sterilized milk is defined in the same publication as follows: Sterilized milk is milk that has been heated at the temperature of boiling water or higher for a length of time sufficient to kill all organisms present. The term " pasteurization," as applied in a commercial sense, has been employed to denote all cases where milk is subjected to heat with the view, actually or ostensibly, as the case may be, of eliminat- ing all prejudicial germ life, though with the real purpose in many instances of complying constructively, though not effectually, with the requirements of law and of an awakened public that it be sub- jected to the pasteurizing process to give assurance of its freedom from live deleterious organisms. So variant have been the methods employed for pasteurizing milk, both as to the degree of heat to which exposed and the term of exposure, that many authorities have suggested the coinage, or application at least, of some new term to express pasteurization when effected in the manner agreed by compe- tent bacteriologists as calculated to destroy the pathogenic micro- organisms without at the same time destroying the nutritive value of the milk and its facility of digestion. 1 Circular No. 19, Bureau of Chemistry, U. S. Department of Agriculture. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 91 Pasteurization as applied to milk consists properly in heating this commodity for a short period of time at a temperature considerably below the boiling point (212° F.), followed by rapid chilling, the object being not so much to preserve the milk as to destroy the harm- ful bacteria and their products. In this connection caution should be exercised to distinguish between sterilization as commonly under- stood and pasteurization scientifically attained, for in sterilizing the milk is heated at least to the boiling point, a temperature which com- pletely annihilates all germ life, whether pathogenic or otherwise, and which treatment is shown to deprive milk to a certain extent of its nutrition and digestibility. TEMPERATURE AND LENGTH OF EXPOSURE BEST SUITED TO PASTEURIZATION. Varying temperatures and durations of exposure of milk to the heating process have been suggested by different observers as best calculated to insure the complete destruction of the disease-breeding micro-organisms without at the same time destroying the enzymes or ferments in the milk, which are generally recognized as playing a most important part in facilitating its digestion. Milk treated in the proper manner is rich in enzymes, retains entirely the taste of fresh milk, and is quite as digestible. The following exposures, among others, have been recommended by independent investigators : 140° F. for 15 minutes, 140° F. for 20 minutes, 140° F. for 40 minutes, approximately 154° to 156° F. for 30 minutes, 158° F. for 5 to 10 minutes, and 158° F. for 30 minutes.^ Dr. Coit, who is identified as closely, perhaps, as any other person with the development of sanitary milk production in America, rec- ommends 140° F. for 40 minutes, 150° F. for 30 minutes, 167° F. for 20 minutes, or 190° F. for 1 minute, followed by immediate cooling to between 40° and 50° F. EiScient pasteurization at these tempera- tures and durations does not, according to his observations, destroy the digestive enzymes or nutritive principles in milk, though, on the other hand, it is destructive of all ordinary pathogenic bacteria and also of most other contaminating germs. The two main considerations which control the temperature and time during which milk should be pasteurized are, first, the thermal death points of (1) the pathogenic (disease-breeding) bacteria, and (2) the ferments in the milk. The first named must be surely killed, so as to eliminate danger, and the latter should not be affected suffi- ciently to " devitalize " the milk. So far as may be judged from present knowledge, the best temperature is 60° C. (corresponding to 140° F.) continued for a period of 30 minutes, or 145° F. for 20 min- utes, followed by rapid cooling, which, it should be emphatically noted, is an essentially important part of the process. There is rea- son to believe that a higher degree of heat applied during a shorter interval is not as satisfactory, since in commercial pasteurization the shorter periods are likely to result in imperfect pasteurization, and it is mechanically impracticable to assure the application of a uniform temperature in such cases to the entire body of milk subjected to the process. The pathogenic bacteria succumb to heat at temperatures below those of the ferments in milk, so that in this way the infectious- 1 Bulletin No. 56, Hygienic Laboratory, Public Health and Marine-Hospital Service, d. 650. ^ 92 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. ness may be destroyed without injuriously affecting the beneficial components of the milk. While authorities are not agreed as to the most advantageous degree of heat and the period for which this should be applied to effect perfect pasteurization, there is a substantial disposition among those consulted by the committee in favor of a range of from 140° to 145° F. for an exposure of 20 to 30 minutes (which period shall be interpreted to exclude the time required to attain the prescribed temperature, referring solely to the interval during which the stated temperature is actually maintained uniformly throughout the body of milk under treatment). From the evidence at hand we may therefore safely conclude that the heating of milk to 140° F. for 30 minutes or 145° F. 20 minutes destroys the pathogenic microorgan- isms without injuriously affecting the composition or quality or the milk and without sensibly impairing its food value, the milk retaining the taste of fresh milk and remaining quite as digestible. EFFECT OF PASTEURIZATION ON GERM LIFE. As to the effect of pasteurization upon the germ life in milk. Dr. Melvin, Chief of the Bureau of Animal Industry, observes that, if done at temperatures recommended by the bureau (namely, 140° or 145° F. for 30 or 20 minutes, respectively), while destroying most, if not all, of the pathogenic bacteria, the process will not eliminate all of the lactic acid bacteria, the advantage of destroying injurious germs greatly outweighing any possible loss from the destruction of germs that might be considered harmless. Surg. Gen. Wyman, of the Public Health and Marine-Hospital Service, confirms the statement that pasteurization, if performed at a temperature of 145° F. for 20 minutes, destroys pathogenic bac- teria, but does not destroy the ferments of the niilk^ which latter are understood to play an important role in its digestion and assimila- tion. On the contrary, Dr. Crichton, commissioner of health of Seattle, Wash., asserts that pasteurization destroys the beneficial germs, as it does largely the prejudicial, but that the latter come to the front and multiply with such rapidity that, after a certain length of time, the milk becomes absolutely dangerous. Pasteurization is probably a wise makeshift, he persists, but never to take the place of good, clean, natural milk. Dr. Clemmer, health officer of Columbus, Ohio, contends that friendly germs are more easily destroyed than prejudicial ones. But this view is contradicted by the testimony of most authorities consulted by the committee. Dr. TTnniill is disinclined to admit that milk contains any germs of a beneficial character, but acknowledges that pasteurization if properly carried out will destroy all so-called pathogenic — that is to say, disease-breeding — organisms. According to Dr. Coit, the enforcement of the tuberculin test will, as elsewhere stated in this report, diminish human infection only to the extent that tuberculosis is now disseminated by market milk ; having the effect, in his judgment, of reducing to the extent of about 25 per cent, the number of cases of tuberculosis occurring in children. Human infection from bovine sources would, in his view, be en- tirely obviated, however, by efficient pasteurization. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 93 HELD AND CONTINUOUS PASTEURIZATION. The temperatures and durations of exposure above indicated refer to what is known as " held " pasteurization, or the " holder " process, a specific quantity of milk bein^' retained integrally in what is known as the holder, or pasteurizing receptacle, during the pre- scribed period of time. The " flash " method, or " continuous " pas- teurization denotes where the milk is constantly flowii)e committee is convinced, after an examination into this phase of the subject, that such latter deductions are scientifioally practicable, and may be reasonably taken into account as evidencing unsatisfactory conditions of cleanli- ness, age, and antecedent temperature of milk offered for sale. With reference to the discussion as to whether it is practicable, with due regard to the rights of the producer or dealer, to insist upon a prescribed bacterial count. Dr. Goler, health officer of Eochester, N. Y., remarks : What right has the dealer to talk about right as against the lives of children? 1 Bulletin No. 56, Hygienic Laboratory, Public Healtli and Marine-Hospital Service, p. 453. 110 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. While Dr. Crichton, commissioner of health of Seattle, Wash., adds : It is not right to the legitimate and honest dealer unless we do insist upon a bacterial count, because it gives a dishonest, filthy dealer a chance to sell dan- gerous milk and to unjustly compete with a man striving to produce good, pure, wholesome milli. The feasibility of indicating the maximum number of bacteria allowable in milk offered for consumption is now almost universally accepted, provided, as suggested by the Chief of the Bureau of Ani- mal Industry, the number fixed be not unreasonably low. Surg. Gen. AVyman observes that for pasteurized milk a maximum bacterial standard is indispensable, and probably even more important than inspection. The bacterial count is, he adds, an index to the efficiency of the methods used for the production of a safe milk and. is a check likewise upon the efficiency of the inspection service. NUMBER OF BACTERIA REASONABLY ALLOWABLE. The general milk supply of the city of Washington averaged 11,270,000 bacteria per cubic centimeter in the summer of 1907 and 22,134,000 during the summer of 1906. While the number of bacteria in milk is not quite as important, from the standpoint of public health, as are the species represented and the nature of the bacterial products, it may be stated with satisfaction that cleanliness and a lib- eral use of ice will result in minimizing the total number of bacteria, and thus afford a degree of protection against the dangerous species and their toxic products. Milk containing few bacteria will contain proportionately few or no harmful varieties. And it should be added that most of the prejudicial bacteria do not thrive at all at the low temperature at which milk should be kept in order to keep down the total bacterial content. While milk freshly drawn under ordinary circumstances almost invariably contains bacteria, even when the most careful precautions are exercised against contamination the organisms in such carefully collected milk are shown to be harmless to animals used in laboratory tests, and we may assume that the pres- ence of such organisms in reasonable numbers does not render milk harmful to man. As to the maximum number of bacteria which should be specified as allowable, there is a considerable range of speculation, the figures suggested by the authorities consulted by the committee extending from 10,000 to 3,000,000 per cubic centimeter. A large percentage of those who have given the committee the benefit of their advice, however, favor the imposition of 100,000 as a maximum content. The committee is inclined to the belief, though, that at this stage in the development of a purer milk supply for the District of Columbia, the specification of that number would perhaps be unnecessarily re- strictive, and recommends that, for the present at least, 500,000 be agreed upon as the maximum number allowable for raw milk (not certified), and 100,000 for pasteurized milk. In the judgment of the committee, it may develop in years to come that these numbers should be decreased, especially if pasteurization be uniformly insisted upon, and that the dairymen may then without difficulty readjust conditions to meet what would noAv be regarded as an onerous re- quirement. It has been demonstrated to the satisfaction of the com- THE MILK SITUATION IN THE DISTRICT OF COLUMBIA, 111 mittee that, with reasonable precautions, it is feasible to maintain an average content of 20,000 to 50,000 bacteria per cubic centimeter for raw milk, and the insistence, therefore, that raw milk delivered for consumption in our own community ^should contain not more than 500,000 bacteria per cubic centimeter is, in the opinion of the committee, a reasonable requirement and calculated to have an im- portant influence in protecting the consumer from uncleanly and un- wholesome milk. This requirement as to number of bacteria per cubic centimeter applies, of course, to market milk, certified milk for infant feeding and other clinical purposes being obviously restricted to a much lower maximum, the standard established by Dr. Henry L. Coit, namely, 10,000 bacteria per cubic centimeter, being regarded by almost unanimous consent as the best for the latter purposes. The committee coincides in the feeling that this maximum number should be prescribed for the District of Columbia for certified milk. Dr. William H. Park, of New York City, is authority for the statement that any intelligent farmer can, by the use of sufficient cleanliness and by applying adequate refrigeration with practically no increase in expense, supply milk 24 to 36 hours old which will not contain in each cubic centimeter over 50,000 to 100,000 bacteria. He adds, further, that when only moderate cleanliness is observed, such as can be employed by any farmer without increasing appre- ciably his expense (that is to say, by the employment of clean pails, straining cloths, cans, and bottles; clean hands and a fairly clean place for milking, and by maintaining in decent condition the cow's udder and flanks), the milk when first drawn will average in hot weather not over 30,000 and in cold weather not over 25,000 bacteria per cubic centimeter. This same milk, if cooled to and kept at a tem- perature of 50° F., will not contain at the end of 24 hours over 100,000 bacteria per cubic centimeter. Dr. Park further observes that the maximum number of bacteria to be determined upon as advan- tageously allowable depends on the size of the city or town, for the reason that the longer the haul the poorer the bacterial quality of the milk. In his judgment, certified milk should average under 10,000 bacteria per cubic centimeter ; pasteurized, under 50,000 ; and common market milk, under 100,000 in winter and under 500,000 in summer. Dr. Hamill, who has devoted large attention to the study of the relation of milk to the problems of public health, believes that it should be the aim of every municipality to so safeguard its milk supply as to attain a maximum standard of 100,000 bacteria to the cubic centimeter. The practicability of establishing a maximum bacterial content for milk commercially used may be assured from the fact that Boston, Rochester, and other communities have prescribed standards ranging from 100,000 to 500,000 bacteria per cubic centimeter. The regulations for the grading and sale of milk promulgated by the Boston Board of Health, specify, among other things, that no person shall sell or deliver any milk or cream containing more than 500,000 bacteria per cubic centimeter. Among the rules regulating the pasteurization of milk and milk products adopted for the city of Chicago is the requirement that milk and skimmed milk shall not contain more than 100,000 bacteria per cubic centimeter from May 1 to September 30, and not over 50,000 112 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. bacteria per cubic centimeter between October 1 and April 30; also that cream and ice cream shall not contain more than 200,000 bacteria per cubic centimeter during the first-named period and not over 100,000 bacteria during the remainder of the year. Dr. Woodward believes that, in the present state of the production and vending of milk, 500,000 bacteria per cubic centimeter repre- sents a fair standard for good, raw milk. In the case of pasteurized milk, the standard should, in his judgment, be fixed not in excess of 50,000 bacteria per cubic centimeter. He goes on to add that, if bacteriological standards are to be fixed by law, it might be well to provide generally that no milk should be sold having a higher bac- terial content than that claimed for it by the vendor. Although a maximum bacterial count of 500,000 per cubic centi- meter of raw milk is recommended by the committee as proper to be established for the District of Columbia, an examination of the limitations placed in other jurisdictions and of the opinions of recognized authorities on the subject induces the committee to the deduction that a specification of 100,000 bacteria per cubic centi- meter would perhaps be better calculated to afford the desired assurance against possible infection from contaminated milk; but the committee defers in this regard to the judgment of the local health officer, and of the members of the Washington milk conference, who favored the fixing of 500,000 bacteria as the maximum allowable. It has been represented before the committee that a maximum bacterial content should not be prescribed for the reason that it is physically impossible for the producer or dealer to verify or dis- prove the analyses depended upon for prosecution by officers of the law. WTiile it is the practice in taking samples of milk to leave one portion with the dealer or storekeeper and retain the other for official examination, it is obvious that the sample reserved by the merchant might easily be so handled or contaminated that its bac- terial content would differ from that shown by the analysis of the officials representing the Government ; but such comparative analysis made at the instance of the dealer might in all probability be rea- sonably expected to result unfavorably to his interests, since, owing to the treatment accorded the milk, the sample reserved by the dealer for examination would likely show a higher bacterial count than that evidenced by the official analysis. The delay in obtaining the result of such bacterial examinations, in addition to the necessities of administration, affords an added reason why this consideration should not be permitted to interfere with the promulgation of a regulation or enactment of a law providing for a maximum content of 500,000 bacteria per cubic centimeter. CONCLUSIVE HAKMFULNESS OF HIGH BACTERIAL CONTENT. There has been some question as to whether the harmfulness of a high bacterial content has been definitely established, but there can be no successful contradiction, in the minds of the committee, that such a showing unquestionably indicates insanitary conditions. The authorities consulted by the committee agree that, as set forth by Dr. Levy, chief health officer of Richmond, Va., the bacterial count, when applied under standard conditions, furnishes thoroughly reliable comparative figures, affording positive indication that some- THE MILK SITUATION IN THE DISTEICT OF COLUMBIA. 113 thing is wrong — either dirty production, failure to cool the milk promptly and eiRciently and to keep it cool, or that it has been kept too long. In the report of the committee of the American Public Health As- sociation suggesting standard methods for the bacteriological exam- ination of milk, it is stated that — A high bacterial count in milk indicates lack of cleanliness in production or lack of care after production. Age of the milk is also an important factor, and in interpreting results the distance milk has to be brought, etc., should be taken into consideration. Thus a count of 100,000 bacteria to a cubic centi- meter should be considered a serious contamination in milk which may be delivered to the consumer within a few hours of production, while a count of no higher than 100,000 in milk produced, at a distance and, say, 24 to 36 hours old is evidence of ordinarily good care. To produce a milk averaging under 10,000 bacteria to the cubic centimeter requires the utmost care and watchfulness of each detail. The report, in referring to leucocytes, states that these bacteria are present in all normal milks, and that their number occasionally fluctuates greatly without apparent cause. Milk from animals suffer- ing from udder inflammations, it asserts, most constantly shows a high leucocytic content, and is without question unfit for human consump- tion; and while a leucocytic count of 500,000 or more to the cubic centimeter in the case of a single animal may be transient and negligible, when found in mixed milk it is sufficient evidence to warrant the exclusion of such milk from the market until satisfactory veterinary inspection of the herd may be made. Dr. Coit, the father of the American medical milk commissions, states that a high bacterial content may indicate, in addition to filthy dairy surroundings and careless collection and handling, a diseased udder. It does not, he maintains, require expensive equip- ment to obtain clean milk; in Kentucky, for example, five dairies, with whitewashed barns and ordinary domestic cleanliness, being ap- proved and certified by a medical milk commission, with counts never above 4,000 bacteria per cubic centimeter. STANDARDS FIXED IN PURSUANCE OF FEDERAL FOOD AND DRUGS ACT. In pursuance of authority granted by the food and drugs act of 1906, the Bureau of Chemistry of the United States Department of Agriculture has prescribed the following requirements for market milk in interstate commerce : It must be the fresh, clean, lacteal secretion obtained by the complete milking of healthy cows, properly fed and kept, excluding that obtained within 15 days before and 10 days after calving; and must contain not less than 8.5 per cent solids not fat and not less than 3.25 per cent of milk fat. Bacteriologically it must not contain more than 500,000 bacteria per cubic centimeter for market milk; not more than 100,000 for inspected milk; not more than 10,000 for certified milk. In enforcing these standards, the kind of bacteria present in milk may modify judgment as to its quality, and, when practicable, sani- tary inspection of dairies and creameries furnishing the product is also taken into consideration. UNIFORM PROCEDURE IN BACTERIOLOGICAL EXAMINATIONS. With a view to securing approximately uniform results as to the content shown by bacteriological examinations, a committee was ap- 82444°— S. Doc. 863, 61-3 8 114 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. pointed by the laboratory section of the American Public Health Association in 1905 to study the various methods used for the bac- teriological examination of milk and to recommend a uniform pro- cedure. In 19.07 the committee prasented a preliminary statement, treating the subject matter in considerable detail. In 1908 a report of progress was submitted to the annual meeting of the laboratory section covering some points on which no recommendations were made in the preliminary statement. These two preliminary reports have been favorably received and the technique recommended has been adopted. The final report presented in 1910 was practically but a restatement of methods theretofore tentatively recommended. The latest report is comprehensive in character, embracing recommenda- tions on every feature connected with the bacteriological examination of milk, including carefully prepared directions concerning the col- lecting of samples, the quantity of milk required for analysis, collect- ing apparatus, means of identifying samples, temperature, media, plating, incubation and counting, milk sediments, tests for special bacteria, gas production, and interpretation of results. The report explains fully a feature which is most mystifying to the layman, namely, the method of diluting the samples and esti- mating with reasonable accuracy the millions of bacteria often in- cluded in a single cubic centimeter of milk. Our curiosity is inten- sified when we are told that a cubic centimeter represents in volume about 16 drojDS, or one- fourth of a teaspoonful. The report suggests a uniform, systematic manner of stating the results of bacteriological counts, below 50,000 being distinguished by five-thousandths, be- tween 50,000 and 100,000 by ten-thousandths, between 100,000 and 500,000 by fifty-thousandths, between 500,0p0_ and 5,000,000 by hun- dred-thousandths, and above 5,000,000 by millions. The actual count under the microscope is facilitated by ruling off a square millimeter of the counting chamber into 400 smaller equal squares. COMPULSORY PASTEURIZATION WOULD NOT DISPENSE WITH NECESSITY FOR PRESCRIBED BACTERIAL COUNT. There is most substantial accord among the authorities consulted by the committee with the proposal that compulsory pasteurization should not be permitted to do away with the requirement of a pre- scribed bacterial content, which latter, in the judgment of those hav- ing knowledge of the subject, is an indispensable accompaniment to regulations compelling pasteurization. The bacterial count is an ab- solute index not only of the efficiency of pasteurization, but likewise of the conditions under which the milk has been kei)t after pasteur- ization. The Surgeon General of the Army observes that the neces- sity for a prescribed bacterial content is not thus obviated for the reason that pasteurization does not make dirty milk clean and does not destroy the toxins which msij develop in old milk. Dr. Melvin aptly observes that the bacterial count is an important aid in bring- ing about sanitary conditions on dairy farms, and should not be abandoned even though compulsory pasteurization be adopted. Free- man remarks that compulsory pasteurization adds to the necessity for a prescribed bacterial content, for the reason that commercially pasteurized milk is usually recontaminated to a greater or less extent before it is disposed of. Dr. Winslow adduces that the advisability THE MILK SITUATIOIST IN" THE DISTRICT OF COLUMBIA. 115 of regulating the maximum bacterial content is not at all altered by- compulsory pasteurization. The milk must, he asserts, be kept as clean as possible before pasteurization, then pasteurized for com- plete safety, and then properly handled afterwards. The Walker- Gordon Laboratory in this city states that, in its judgment, compul- sory pasteurization would greatly increase the necessity for careful supervision of the bacterial content, so as to insure against the more dangerous organisms that might survive the pasteurization. Dr. Prescott, of the Massachusetts Institute of Technology, remarks that compulsory pasteurization would not eliminate the necessity for a prescribed bacterial content, but that it would make it possible to establish it at a lower level, say, 50,000 bacteria per cubic centimeter. NECESSITT FOR ADDITIONAL PRECAUTIONS. The necessity for additional requirements as to cleanliness, fresh- ness and purity of milk, the failure to observe which may be de- tected by the bacterial count is apparent^ when we realize that, in addition to being warm, much of the milk of Washington City is dirty ,^ 121 of the samples examined showing a visible deposit of dirt in the original container after standing several hours, which was found upon microscopic examination to be composed of fecal matter, hairs, straw, and all manner of extraneous substances that have no place in clean milk. When we consider that the solid impurities that reach the consumer are only a fraction of the total solid impuri- ties with which milk has been in contact (since other larger bodies have been previously removed by the process of straining to which it is subjected before it is poured into the containers in which it is sold), we may readily appreciate the fact that the condition of milk offered for sale is even more dangerous than its superficial appearance indicates. It is additionally urged by Dr. Woodward, health officer, that the bacteriological examination of milk as it reaches the city will enable the identification of farms which are persistently sending in milk containing such relatively large numbers of bacteria as to surely indicate faulty methods of milking and handling milk. APPARENT ANOMALY AS REGARDS SOUR MILK. It is a matter of curious interest why sour milk and its products are considered a safe food to be consumed raw, when stale sweet milk is looked upon with suspicion. This apparent anomaly may be explained by the circumstance that, for a long time after milk is drawn, all the bacteria in it increase in number, this increase being more or less rapid and depending chiefly on the temperature at which the milk is kept, and some of these bacteria may be the kinds that produce disease. Finally, however, when milk sours the harmless lactic-acid bacteria and the lactic acid which they produce tend to destroy the other microorganisms, including the disease-producing bacteria, so that by the time the milk is sour it is practically free from harmful germs. 1 See Bulletin No. 35 of the Hygienic Laboratory, Public Health and Marine-Hospital Service, p. 71. 116 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. IX. Care of Milk in the Home. PRECAUTIONS RECOMMENDED. Too miicli attention can not be given to the projjer treatment of milk in the home, which subject is handled most capably in a bulletin issued by the Department of Agriculture as late as August 30, 1910,^ in which it is set forth that the contamination of milk in the home results generally from (1) placing it in unclean vessels, (2) expos- ing it unnecessarily to the air, (3) failing to keep it cool up to the time of use, and (4) exposing it to flies. Among the items of care which should be scrupulously exercised by the housekeeper to pre- vent contamination of the milk, the following are particularized : Milk from the grocer or baker, kept by the dealer in a can open much of the time and possibly without refrigeration, is dangerous and should be avoided. Never buy bulk milk from a grocery store. Never buy milk for the baby from a grocery store. Store milk has often been kept over from the day before. Such milk is dangerous as a food for babies. If it is impossible to get bottled milk, do not set out over night an uncovered vessel to collect thousands of bacteria from the street dust before milk is put into it, but have the milk delivered personally to some member of the family if possible. If this be impracticable, set out a bowl covered with a plate, or, better still, use a glass preserving jar into which nothing but milk is put, which jar should have a glass top with the rubber band omitted. A pitcher can not be tightly cov- ered on account of the projecting spout. Milk tickets or written instructions intended for the dairyman are likely to become more or less soiled, and if used should not be placed in the bowl or jar. The milk should never be exposed to the sun for any length of time. It frequently happens that milk delivered as early as 4 o'clock in the morning remains outdoors until 9 or 10 o'clock. Al- though this practice is to be condemned, if it be inconvenient to re- ceive the milk soon after its delivery, the housekeeper should indicate to the driver a sheltered place or provide a covered box in which the milk pail or bottle may be left. It is important that the milk should be taken into the house as soon as possible after delivery, par- ticularly in hot weather. The milk should, upon receipt, be placed in the refrigerator at once and allowed to remain there when not using from it, constant endeavor being exercised to keep the milk at all times, except when actually on the table, at a temperature not exceeding 50° F., for the reason that harmful bacteria increase with astonishing rapidity once milk rises above this temperature. .Unless the milk bottle is kept in actual contact with the ice, it will be colder at the bottom of the refrigerator than in the ice compartment, since the cold air settles rapidly. Milk should be kept in the original bottle until needed for imme- diate consumption ; do not pour it into a bowl or pitcher for keeping ; 1 " The Care of Milk and Its Use in the Home," by George M. Whitaker, L. A. Rogers, and Caroline L. Hunt, Farmers' Bulletin No. 413. THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 117 pour out only the amount which will be consumed at one meal ; care- luUy wipe or rinse the bottle, especially its mouth, before pouring milk from it ; see that dust or dirt which may have gathered thereon or on the cap will not get into the milk; do not pour back into the bottle milk which has been exposed to the air by being placed in other vessels; keep the bottle covered with the paper cap as long as milk is in it and when not actually pouring from it ; do not expose uncov- ered milk in the refrigerator; if the paper cap has been mutilated, cover the bottle with an inverted tumbler. Keep the refrigerator clean and sweet ; see that the outlet for water formed by the melting ice is kept open and that the space under the ice rack is clean. The refrigerator should be scalded each week. As soon as the milk bottle is empty rinse it in lukewarm water and place it in an inverted position to drain. Do not use it for any other purpose than for milk. All utensils with which milk comes in contact should be rinsed, washed, and scalded every time they are used; do not employ for this purpose dishwater which has been used for washing other utensils or wipe them with an ordinary dish towel — it is better to boil them in clean water and set them away undried. Eemember that exposure of milk to open air invites contamination, not only from, odors and bacteria-laden dust, but also from flies, which scavengers are a prolific source of contagion in conveying germs of typhoid fever and other diseases from the sick room or from excreta to the milk. Do not keep milk over 24 hours even if it seems to be sweet, since milk may become unfit for human food and deleterious to health be- fore it sours. The foregoing suggestions should be observed with regard to pasteurized milk, as well as with ordinary raw milk, for while effi- cient pasteurization destroys disease germs and affords a safeguard against certain dangers, it can not be regarded as an insurance against future contamination of milk. To the foregoing might appropriately be added the following : Do not boil the milk — that is to say, allow it to attain a temperature as high as 212° F. — since the milk is devitalized thereby, and not only its nutrition but its digestibility is impaired. Do not allow the milk to stand in the kitchen, where the tempera- ture is likely to increase rapidly. Do not mix " old " and " new " milk together ; that is to say, do not subject the new supply to contamination with the increased num- ber of bacteria which may be expected to exist in the supply pre- viously received. If a case of typhoid fever or other contagious disease breaks out in your house notify the health authorities (through your physician) at once, and also your milkman. During such illness do not allow the dairyman to take away milk bottles from your house until after recovery of the patient, since one of these bottles might otherwise be the means of carrying the disease to some other household. It should be recog-nized as the duty of every householder, especially of every parent, to ascertain at the health department in the District Building the record of the dairyman from whom his or her supply of 118 THE MILK SITUATION IN THE DISTKICT OF COLUMBIA. milk is received. It may not be generally known that every consumer of milk is privileged to consult at the health office the record of his individual dairyman, affording an available and easily accessible means of protecting himself and his family from greater imminence of danger from infection through the agency of milk than may other- wise be necessary. It has been the practice for some years past to maintain, by the use of score cards, a tangible record of the intelligent cleanliness exercised by each local dairyman in the conduct of his business, and the committee recommends, especially where there are children in a family, that the parent avail himself by consulting the health office records of this means of ascertaining whether his family is securing the quality of milk to which it is entitled. As previously indicated, the committee is disposed to recommend, as suggested by the Washington milk conference of 1907 and by the special committee on the Straus Laboratory recently appointed by the District Commissioners, that these records of the health depart- ment be periodically published in the daily press. OBSERVANCE OF PRECAUTIONS BY CONSUMERS. An inquiry propounded by the committee as to whether, in the view of persons consulted, requirements could reasonably be made by the District authorities compelling consumers to exercise caution in handling milk when received at the home, develops an expression of the belief that such a proposal would be impracticable. Borden's Condensed Milk Co., however, offers the suggestion, in this connec- tion, that consumers be compelled to thoroughly clean and scald any and all utensils containing milk, which containers are to be returned to the dealer. The Chief of the Bureau of Animal Industry ob- serves that educational work is believed to be the best method of inducing consumers to exercise caution in handling milk, and invites attention to the recently published bulletin of the Department of Agriculture, above referred to, which is well adapted for this pur- pose and which is being widely circulated.^ X. Infant Feeding and Infants' Milk Depots. cow's MILK AS INFANT FOOD. The dairy cow fills a unique place under the conditions of our present civilization, since her living body is the source of milk, the most important of all human foods and absolutely essential for all infants during the first few years of life (except while nursed at the mother's breast). Even when children have matured beyond the period during which milk is an essential article of food, its use as a beverage and in the manufacture of butter, cheese, and ice cream is an almost indispensable element in their dietary. The complex demands of modern living and the necessity on the part of many mothers of earning a livelihood, often making it im- practicable for them during the hours of daily toil to nourish their offspring, has created in recent years an essential demand for cow's 1 " Care of Milk and Its Use in tlie Home," Farmers' Bulletin No. 413, U. S. Depart- ment of Agriculture. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 119 milk for infant feeding, prepared in some cases in accordance with certain prescribed formulae intended to approximate as nearly as possible the composition of mother's milk. ESTABLISHMENT OF INFANTS' MILK DEPOTS. To meet this necessity, milk depots have been established, largely under philanthropic auspices, in many of the principal cities of America and Europe. The first depot in the United States was in- stituted in 1889. The movement was accelerated in 1892, when Dr. Henry L. Coit, of Newark, N. J., formulated a plan for the produc- tion of pure milk under the auspices of medical milk commissions. In 1893 the Medical Society of Essex County, N. J., adopted the plan and organized the first medical milk commission in the United States. The commission contracted with a dairyman^ (for terms of agreement see Appendix AO) to produce milk according to the standards of purity formulated by Dr. Coit in connection with the original plan. A recent report by Asst. Surg. Gen. J. W. Kerr, of the United States Public Health and Marine-Hospital Service,- presented before the American Association of Medical Milk Commissions on June 6, 1910, recites that 28 cities in the United States are now supplied with infants' milk depots and milk dispensaries for the relief of the poor, many of these institutions maintaining substations for the distribution of milk and imparting advice with respect to infant hygiene. It may be noted in this connection that the local Straus pasteuriza- tion laboratory has six substations geographically distributed with a view to meeting the convenience of the largest number of patrons of the poorer classes. The milk is received at the local laboratory before 8.30 a. m., and is modified and pasteurized before 11 a. m., affording a much more rapid delivery into the hands of the consumer than is the practice among local dairies in the distribution of unmodified and unpasteurized milk. A physician is in attendance also during certain hours daily to indicate the formula best suited for each particular infant. CERTIFIED MILK. The standards of purity formulated by Dr. Coit in 1893 gave rise to the term " Certified milk," and the precedent then established has since been followed in many cities of the country, not less than 63 commissioners having since been organized to encourage the production of pure milk for clinical purposes. Without the establishment of these voluntary supervisory commissions it would be impossible to provide jDractically for the production of certified milk, which latter high-grade product has grown to be so important a factor in facili- tating the healthy growth of infants and in accelerating the recupera- tion of invalids. Specific bacterial standards for pure milk have been adopted, limiting the number of bacteria allowable and inhibiting the pres- ence of pathogenic organisms. The numerical standard fixed in most ^ Bulletin No. 56, Hygienic Laboratory, Public Health and Marine-Hospital Service, March, 1909, pp. 615-619, inclusive. 2 Public Health Reports, No. 50, Washington, 1910. 120 THE MILK SITUATION IN THE DISTKICT OP COLUMBIA. cases for certified milk is a maximum of 10,000 bacteria per cubic centimeter. The requirements fixed upon for certified milk contem- plates especially that none but healthy cows shall be employed ; that extraneous contamination of their milk shall be reduced to a mini- mum; that the milk shall be cooled to 45° F. to prevent bacterial growth; and that it shall reach the consumer before noticeable bac- terial changes have occurred therein. BREAST FEEDING DECIDEDLY PREFERABLE TO BOTTLE FEEDING. The committee wishes to emphasize in the most forceful manner the extreme importance of feeding, at the mother's breast, as opposed to artificial feeding with cow's milk. It is a well-known fact that the rat© of mortality during the first year of infants fed on human breast milk is markedly less than among bottle-fed babies. The milk of the cow is directly responsible for the death of a very con- siderable percentage of infants. Nature did not intend the young of one species to be raised upon the milk of another, much less did it intend that that milk should be dirty, stale, and bacteria-laden. Cow's milk may be prejudicial to health either because the milk is physiologically unsuitable, as for infant feeding, or because it has become a medium of infection through contamination with various disease germs. Milk of inferior nutritive value, furthermore, must indirectly have a deleterious influence on the health of the infant, and particularly so when, as in the case of babies, milk is exclusively used as food. During the first year of its life a child consumes, it is estimated, about 500 quarts of milk. There is abun- dant evidence to show that the proportion of deaths among infants would be greatly reduced if they received the food nature designed for them, namely, mother's milk. An eminent authority on the rela- tion of mortality to artificial feeding of infants concludes that, taking the period of the first year of life, the number of deaths resulting from epidemic diarrhea among breast-fed babies is not much more than one-tenth the number occurring among artificially- fed infants. There is no doubt that the nursing of all infants by healthy mothers would contribute tremendously to the reduction of the infantile death rate. It has been said that there is only one other period in life in which the chance of death is greater than in the case of infants under 1 year of age, and that is in persons over 90 years old. This comparison emphasizes the extreme importance of providing milk, especially for infant consumption, which shall be physiologically suitable for assimilation and as free as possible from impurities. It should be animadverted to in this connection as emphasizing the important influence of providing milk free from impurification, that during the period elapsing since the passage of the local milk- inspection law in 1895, the annual death rate of infants in the Dis- trict of Columbia has decreased from 194 per 100,000 population to 86 per 100,000.^ This marked diminution may fairly be attributed in large measure to the beneficent effects of this law. 172 per 1,000 In 1909, increasing to 86 in 1910. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 121 MODIFIED MILK. The term " Modified milk " is claimed to have been originally used by the Walker-Gordon Laboratories, to describe milks that have by the addition of water and milk sugar, and at times barley water and limewater, been mechanically changed in their chemical consti- tuents to fill physicians' prescriptions, and to increase or decrease these constituents according to an exact method, so that physicians may be enabled to order a milk that can be adjusted to meet the needs of the individual case for which it is prescribed. If the child be artificially fed, there is reason to believe that milk, when modified to conform as nearly as possible to the composition of mother's milk, comes nearest to supplying the demands of the infant, and it is to meet this very considerable and constantly increasing dem^and that certain formulae hav^ been prepared for feeding the infant during the successive stages of its early existence. NUTRITIVENESS OF MODIFIED MILK. No adequate comparison can be made between modified milk (raw or pasteurized) and ordinary market milk as regards its nutritive qualities, since milk is customarily modified according to physicians' prescriptions for special use, and while designed in many instances to furnish a more easily digested and assimilated food than whole milk, is supposably, in other instances, less digestible than milk in its natural state. Aside from is facility of digestion ordinarily, modified milk is prescribed with a view to furnishing the maximum amount of nutritive food which may be absorbed without prejudice. Modified milk may, it should be added, contain a greater or less pro- portion of each nutrient found in raw milk. Its use is especially recommended for infants, invalids, and convalescents. The Straus Laboratory, of this city, contends that modified milk is as nutritious and more so than raw milk, since it is an attempt to reproduce mother's milk as closely as possible, and is changed to suit the vary- ing ages and strength of babies. Dr. G. Lloyd Magruder, of this city, has addressed a letter to President Taft, asking that the Department of Agriculture and the Public Health and Marine-Hospital Service of the Treasury Depart- ment be directed to investigate the relative, merits of raw and pas- teurized milk for infant feeding. It is believed that a careful ex- amination into this important subject by these departments of the United States Government would be of inestimable value in affording an authoritative basis for harmonizing the differences of opinion which have existed for many years past on this vital question. SUSCEPTIBILITY OF MODIFIED MILK TO DETERIORATION. As to the relative susceptibility to deterioration. Dr. Melvin states that there is probably no difference between modified and whole (raw or pasteurized) milk in this respect, if both are obtained and handled under similar conditions. 122 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. RELATIVE COST OF MODIFIED MILK. Modified milk is as a rule higher in price than whole milk, being naturally more expensive since it is prepared in accordance with physicians' formulas, and requires expert knowledge in its modifica- tion. The Straus Laboratory in Washington states that the addi- tional ingredients called for, the time required, and the necessity of trained help in modifying makes its cost much more than would be demanded for whole milk. This statement is corroborated by the Walker-Gordon Laboratory of this city, which announces that modi- fied milk is much more expensive in that intelligent persons must be trained for its preparation. The health officer of Cleveland, Ohio, reports that it costs from 2 to 9 cents per quart in excess of ordinary market milk. The following schedule of prices for whole 'milk, modified milk, and barley water, sold by the Washington branch of the Straus Pasteurized Milk Laboratories, has been furnished through the courtesy of Miss Eeba J. Hurn, local representative: Whole milk: Per pint, 4 cents; per quart, 8 cents. Modified milk : No. 1, 8-ounce bottle, 1^ cents ; per quart, 6 cents, on same basis. No. 2, 6-ounce bottle, li cents; per quart, 8 cents, on same basis. Six bottles a day's feeding. No. 3, 3-ounce bottle, 1 cent ; per quart, 10§ cents, on same basis. No. 4, 3-ounce bottle, 1 cent ; per quart, lOf cents, on same basis. Eight bottles a day's feeding. Barley water : 3-ounce bottle, 1 cent ; per quart, lOS cents, on same basis. 6-ounce bottle, li cents ; per quart, 8 cents, on same basis. Park asserts that even if it were possible to bring all milk up to a prescribed standard of purity, which would make it safe to be ingested unheated by an infant, it would in his judgment be an absolutely unwise procedure on account of the cost, which would be increased far more than the value of the milk for most purposes for which this commodity is used. "Most of us who have studied the question," he says, "believe that proper pasteurization under rigid inspection is the method by which a safe, wholesome milk supply can be provided." infants' MILK DEPOTS. The committee refers with especial pleasure to the magnificent work being accomplished by infants' milk depots throughout the country and the decided stimulus accorded to the movement by the public-spirited generosity of Mr. Nathan Straus, of New York City, whose practical philanthropy has resulted, either directly or inci- dentally, in instituting since 1892 10 principal depots for the dis- tribution of modified and pasteurized milk.^ It is interesting to note that, prior to the movement inaugurated by Mr. Straus in New York City in 1893 for dispensing pasteurized milk, the annual death rate of children under 5 years of age in the metropolis was 96.2 in every 1,000, and in June, July, and August (when exceptional care was required to be taken to properly cool the 1 Straus depots have been established in New Yr-k City, Chicago, Philadelphia, St. Louis, Newark, N. J., and Washington; also in Munich, Karlsruhe, and Sandhausen, Germany, and Dublin, Ireland. Mr. Straus donated, besides, the plant installed at the depot, already in operation, at Liverpool, England. THE MILK SITUATIO]Sr IN THE DISTRICT OF COLTJMBIA. 123 milk) the death rate was 136.4 for each 1,000. With the increased use and distribution of pasteurized milk the death rate in New York City had already in 1906 dropped to 55 per 1,000, and for the months of June, July, and August of that year averaged 62.7 per 1,000. The milk supply was from the same farms and the same kinds of herds as before, and distributed in the same way, the only difference being that the bottles were sterilized and the bacteria in the old, dirty, warm milk had been killed by the heat applied to pasteurize it, this being followed by proper cooling. The extent of the work of the New York agency may be appreciated when it is stated that in the year 1906 17 of these Straus stations dispensed 3,142,252 bottles and 1,078,405 glasses of pasteurized milk. The milk of the Straus pasteurizing laboratories is prepared in accordance with formulae recommended by the foremost specialists in the treatment of children's diseases, Formula No. 1, prescribed by Dr. Arthur E>. Green, containing milk, cane sugar, salt, and oat water; Formula No. 2, by Dr. Rowland G. Freeman, containing milk, limewater, milk sugar, and filtered water; Formula No. 3, by Dr. A. Jacobi, comprising milk, barley water, cane sugar, and table salt; Formula No. 4, by Dr. Freeman, consisting of skimmed milk, milk sugar, limewater, and filtered water; and Formula No. 5, by Dr. Green, including cream, milk, limewater, milk sugar, and filtered water. The several formulae are prescribed in sequence for infants at successive stages of their development, from date of birth to time of weaning or later. Barley water, prepared in accordance with a specific formula, is also separately supplied by these laboratories. A more detailed statement of the formulae employed by the Straus local infants' milk depot is submitted herewith (Appendix AP). The committee has inspected the Washington Straus depot and is impressed with its importance in conserving the life and health of infants who, for one reason or another, are obliged to be fed other than at the mother's breast. While it is not deemed wise to en- courage the artificial feeding of babies, the necessity for the main- tenance of this establishment or some similar agencies must be con- ceded. In other communities depots of this character have been in- stituted at the initial expense of Mr. Straus and other philanthropists, and later taken over and maintained at public or private expense under the supervision generally of municipal health officials or medi- cal milk commissions. It is understood that, having demonstrated locally the great usefulness of this enterprise, its promoter will, unless its maintenance be assumed by our municipality or by private sub- scription, close its doors and deprive the citizens of Washington, rich and poor alike, of this splendid instrumentality for reducing the death rate of infants in this community. The committee adverts to the fact that apparent indifference has been manifested on the part of Washington physicians generally, toward utilizing the facilities afforded by the Straus Laboratory for supplying modified milk for infant feeding. It is hoped that this seeming apathy toward the use of modified milk prepared under scientific, skillful direction, will be superseded gradually by active, earnest cooperation on the part of the medical fraternity in sup- porting this worthy foundation, or similar establishments operating on a commercial basis, which latter, it is understood, are prepared to render efficient service to the public in this direction. 124 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. DISPOSAL OF LOCAL STRAUS DEPOT. At the suggestion of the Washington representative of the Straus Pasteurizing Laboratories, a public hearing was held by the Dis- trict Commissioners on November 30, 1910, to discuss what action should be taken with regard to the proffer to the District govern- ment by Mr. Straus of the plant established at 1319 H Street NW., in this city, with the sole restriction that milk furnished therefrom should be dispensed as a charity and not as an ordinary commercial enterprise. At the close of the hearing, the commissioners appointed a committee to examine into the matter and make recommendations as to the proper course to be pursued by them in the premises. This committee was composed of Gen. George M. Sternberg (chairman), Mr. E. J. Stellwagen, Mr. Hennen Jennings, Dr. George M. Kober, Mr. Arthur C. Moses, Mr. Walter S. Ufford, Mr. George S. Wilson, Dr. H. F. Sawtelle, and Mr. J. Louis Willige. The committee, in its report submitted under date of December 7, 1910, a copy of which is appended (Appendix AQ) , recommends to the commissioners that Mr. Straus be prevailed upon, if possible, to continue the existing plant until such time as provision may be made for furnishing an ample and safe supply of pasteurized and modified milk through commercial channels under the direct supervision of the District health department, the committee deeming it impracticable for the District government itself to undertake the management of such a plant with advantage. The committee suggests the desirability, however, of utilizing the existing plant for the conduct, under the Department of Agriculture or the Public Health and Marine-Hospital Service, of investigations relative to the value of pasteurized and modified milk for infant feeding. In the event that the Straus Laboratory be not continued as a charity, it is suggested that the providing of proper food for infants among the indigent classes be supported by generous contributions toward the funds for maintaining such existing agencies as the diet kitchen, the Citizen's Relief Association, the Associated Charities, and the Instructive Visiting Nurse Society. The report proceeds to recommend prompt and adequate legisla- tion for supplying a clean, pure, wholesome milk supply for the Nation's Capital, and urges that the inmates of foundling asylums, hospitals, and other institutions supported wholly or in part from public funds be furnished with milk conforming to the classification recommended by the Washington milk conference in 1907. It is further advocated, as favored by the conference, that the health of- ficer be required to publish the ratings of dairies, which information it is understood is currently in the possession of the health depart- ment, but up to the present time not published, though conveniently accessible to any citizen of Washington who may call at the District Building for the purpose of consulting the records. The report concludes with an indorsement of the recent recom- mendation submitted by the health officer that six visiting nurses be appointed to give instruction in the public schools regarding matters affecting the health of pupils. Since the above hearing, Mr. Straus addressed a letter to Senator Gallinger, chairman of the Senate Committee on the District of Columbia, stating his willingness to continue the laboratory in Wash- THE MILK SITUATION IE" THE DISTRICT OE COLUMBIA. 125 ington several months after January 1, 1911, if requisite in order to allow opportunity for Congress to take over the establishment under governmental control. As a result of the recent agitation on the subject, a bill (S. 9716) was introduced in the Senate by Mr. Gallinger authorizing the ac- ceptance by the United States Government as a gift, of the Nathan Straus Pasteurized Milk Laboratory. The bill was referred to the Senate District Committee, from which it has not yet been reported. The measure proposes to appropriate the sum of $15,000, or so much thereof as may be necessary, to be immediately available for ex- penditure until June 30, 1912, in the maintenance and operation of the laboratory, the sum allotted to be expended under the supervision of the Surgeon General of the Public Health and Marine-Hospital Service " for the purpose of demonstrating, with the cooperation of the health officer of the District of Columbia, the practical utility of infants' milk depots in the reduction of infant mortality." A copy of the bill is subjoined (Appendix AK). While the chamber of commerce committee apjareciates to the full- est extent the valuable results achieved through the benefaction of Mr. Straus in placing this practical object lesson before the eyes of our community, it feels obliged to advert at the same time to the fact that essentially important work in educating the public to an ap- preciation of the value of and necessity for a sanitary milk supply, especially for infant feeding, has been carried on for many years by the Department of Agriculture and the Public Health and Marine- Hospital Service and by Dr. G. Lloyd Magruder, Dr. George M. Kober, Dr. Woodward, the District health officer. Gen. George M. Sternberg, Mr. Emile Berliner, and other well-known public-spirited Washingtonians. As an evidence of the practical work accomplished locally in this direction the committee appends (Appendix AS) a report on the Infants' and Children's Dispensary connected with the Settlement House of southwest Washington, covering the period from April 13, to October 1, 1908, two years before the establishment of the local Straus Laboratory. This dispensary has been continuously in ex- istence since its organization and is doing excellent work. During the first five and one-half months of its career there were treated in the dispensary 261 infants and children. During this period 41 babies were supplied with modified milk. Modified milk was also dispensed at this early date by the Neighborhood House, also located in south- w^est Washington. The committee feels that, so far as ministering to the material wants of infants in this jurisdiction in providing a proper supply of pasteurized and modified milk is concerned, this can probably be accomplished at much less expense through the utilization of exist- ing commercial agencies, such as the establishments of Mr. George M. Oyster, jr., the Walker-Gordon Laboratory, and the White Cross Milk Co., than by the maintenance of the plant so generously in- stalled by Mr. Straus. It is strongly advocated, however, that a special fund be inaugurated by popular subscription, liberally en- dowed and supported by our citizens and possibly supplemented by appropriations from Congress, to be devoted exclusively to reimburs- ing such commercial agencies for pasteurized and modified milk fur- nished upon order in deserving cases to infants whose parents are 126 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. unable to provide, in part or wholly, the cost of the necessary supply of wholesome and nutritious milk, appropriately suited to the infant's needs. While (in the absence of facilities for securing milk prepared at regularly established depots in accordance with specially adopted formula)) pasteurization at home of milk for infants' use, in ap- paratus of which several economical patterns are obtainable in the open market, is qualifiedly recommended, its preparation in this way requires such intelligent and careful manipulation that it is, in the opinion of the committee, better and cheaper to purchase m.ilk already pasteurized under competent supervision, from infants' milk depots or from properly equipped commercial establishments. IMPORTANT FUNCTION OF VISITING NURSES. In this connection the committee feels that a noteworthy adjunct of the local Straus Laboratory, and one which could hardly be ex- pected to obtain in association with a commercial agency furnishing modified milk on a purely business basis, is the stationing of a regis- tered physician at the laboratory at certain specified hours, to give advice free of charge to parents concerning the proper treatment of infants and to prescribe the formula of milk best suited for the infant at the particular period of its growth. Commendable service is rendered in this direction by the Instructive Visiting Nurse Society, which details nurses to the several settlement houses and to the homes of parents for the purpose of imparting practical instruction regarding the bathing, clothing, feeding, and other care of infants. The extreme efficacy of this practical information and active assist- ance extended by the Instructive Visiting Nurse Society in reducing infant mortality is especially recognized, authorities agreeing that proper clothing, bathing, and medical attention constitute as impor- tant a factor in the successful rearing-of the infant as the provision of suitable food in appropriate measure. Dr. Woodward especially recommends that arrangements be made for the instruction of mothers in caring for their infants. This can, he stated, be done in no other connection so well as in conjunction with the free distribution of milk to persons unable to pay for it and the distribution of milk at reduced prices to persons who are unable to pay the ordinary market price for milk of proper quality and composition. The committee recurs to the fact that the superior value of maternal nursing can not be overestimated, it being stated on reliable authority that were mothers able universally to nurse their children from one- third to one-half of the deaths of infants would be prevented, the enormous loss of life occurring among artificially fed infants being undoubtedly due in major portion to bad milk and its improper use as an article of diet. Mothers should be encouraged in every pos- sible way to nurse their infants, regardless of financial or social status, for it has been conclusively proved by extended series of care- ful systematic investigations that the mortality among bottle-fed infants is vastly greater than among those that are breast fed. When breast feeding is clearly impossible, however, a fulsome supply of pure cow's milk, modified to meet the special needs of the infant, should be rendered available for both rich and poor, and mothers THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 127 should be instructed at the same time regarding the special require- ments necessary to successful artificial feeding, including the care of milk in the home. From both economic and sanitary viewpoints infants' milk depots should be provided for improving the physical well-being of the children who are destined to become active, pro- creating members of the population of the future. XI. Prepared Milks. WHAT MAY BE PROPERLY CLASSED AS PREPARED MILKS. Dr. H, W. Wiley, Chief of the Bureau of Chemistry, Department of Agriculture, in defining prepared milk, states that there is a wide variation of ideas which may be properly entertained concerning " prepared " milk, but that he is inclined to the following : Natural milk which has not been treated other than by straining, cooling, and bottling would not be entitled to the term " prepared milk." All milk which has been modified in its composition in any way by changing the properties of its ingredients or by sterilization or pasteurization should be designated as prepared milk. Milk which is used in connection with other foods in a dried or semiliquid state, is not prepared milk, but milk used in compounding other foods. . For the purposes of this report, however, the committee is pleased to regard prepared milk as embracing condensed, evaporated, and powdered milks. As a matter of convenience, skim milk is also included within this chapter. , CONDENSED OR EVAPORATED MILK. Condensed or evaporated milk may, according to information fur- nished by the Bureau of Animal Industry, be defined as milk from which a considerable portion of water has been evaporated, and to which, in the case of sweetened condensed milk, sugar (sucrose) has been added. Condensed milk, synonymously known as evaporated milk, is de- fined in the Standards of Purity for Food Products,^ issued by the Secretary of Agriculture in pursuance of authority given by Con- gress in the food and drugs act of June 30, 1906, as follows : Condensed milk, evaporated milk, is milk from which a considerable portion of water has been evaporated, and contains not less than 28 per cent of milk solids, of which not less than 27.5 per cent is milk fat. Surg. Gen, Wyman is authority for the statement that in the United States Borden's " Eagle " brand of condensed milk may be taken as a type which is said to be prepared by heating fresh cows' milk to 100° C. to destroy the bacteria and evaporating the remaining milk in a vacuum at a low temperature to a little less than one-quarter of its original volume, the finished product being usually preserved in tin cans, after having added about 6 ounces of cane sugar per j)int. Sweetened condensed milk is defined in the Standards of Purity for Food Products^ as follows: Sweetened condensed milk is milk from which a considerable portion of water has been evaporated, and to which sugar (sucrose) has been added, and con- tains not less than 28 per cent of milk solids, of which not less than 27.5 per cent is milk fat. * Circular No. 19, Bureau of Chemistry, U. S. Department of Agriculture. 128 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. It will be remembered that condensed milk, unsweetened, must con- tain, to meet the requirements of the Federal pure food and drugs act, the same minimum percentage of solids (including milk fat) as sweetened condensed milk. Considerable agitation has been discernible in many communities concerning the relative merits of these prepared milks compared, especially so far as their nutritiveness and digestibility are concerned, with raw or properly pasteurized milk. It is stated by the Bureau of Animal Industry that some prepared milks are not as nutritious as raw or properly pasteurized milk, this depending largely upon the character and method of preparation, Surg. Gen. Wyman believing that the proper solution of this question involves the consideration of the individual preparation. NUTRITIVENESS OF CONDENSED MILKS. According to Dr. Wyman condensed milk in the United States is usually low in fat content and excessively rich in sugar. Properly diluted, he says, the best grades of condensed milk ought to contain the same nutriment as the original milk from which it was made, plus or minus whatever is added or removed when finally put up in packages. He adds the caveat, however, that this does not imply the same food value as the original milk. It is declared by Winslow that substitutes are much more dangerous for infants than pasteurized milk, while Dr. Prescott, of the Massa- chusetts Institute of Technology, asserts that condensed milk is not as well balanced a ration as raw milk, since it is likely to be deficient in fats. Dr. Crichton, commissioner of health of Seattle, Wash., observes that most prepared milks are not as nutritious as raw or properly pasteurized milk; that they are harder to digest; are cus- tomarily made from inferior milk, impure in many instances, and containing sugar in unknown quantities, and are consequently unsat- isfactory as food for children and unappetizing and disagreeable in taste. In comparing the nutritiveness of raw and properly pasteurized milk as opposed to prepared milks. Dr. Coit, rating raw milk at 100, assigns a value of 20 to condensed milk and 10 to powdered milk. On the other hand, Borden's Condensed Milk Co. asserts that prepared milk of a recognized standard brand, manufactured and cared for under conditions existing in high-grade factories, is practi- cally a concentrated " properly pasteurized milk " and has all the nutritive qualities of such milk. " Used in the manner in which it is," states this company, " it undoubtedly is as nutritious, or at least so nearly so, as to be on a most debatable ground." SUSCEPTIBILITY OF CONDENSED MILKS TO DETERIORATION. What are known as " condensed " or " evaporated " milks have been somewhat largely represented in our markets for many years past. These milks are customarily prepared by evaporating the water from whole milk until a consistency is reached which (gen- erally, though not necessarily, by the addition of sugar) tends to preserve the milk, its viscosity rendering impossible the multiplica- tion of pathogenic germs and effectually safeguarding the product THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 129 from deterioration, even when the receptacle is kept open for a reasonable length of time. It should be observed, however, that when diluted to the consistency of liquid milk, as commonly used on the table, sweetened condensed milk is in certain respects nearly as susceptible to contamination from various sources as raw or pas- teurized milk, and when exposed to the air its use should conse- quently, as a matter of security, be circumscribed with the same pre- cautions as are recommended for the treatment of raw or pasteurized milk. In the judgment of authorities consulted by the committee, con- densed milk is not so susceptible to deterioration as raw milk, especially if a considerable amount of sugar be added. Condensed milk will, according to Dr. Melvin, keep much longer than raw or pasteurized milk, even after being opened, and there is authority for the statement that if sealed it should resist deterioration indefinitely. Surg. Gen. Wyman of the Public Health and Marine-Hospital Serv- ice specifies that condensed milk either deteriorates or at times contains toxic substances, children having been made very ill from using cans of a certain brand. Such brands as contain a high per- centage of sugar ought, he observes, to keep much better than raw milk, on account of the well-known preserving properties of sugar. Mr. Scott, inspector of milk of Providence, R. I., offers the assurance that condensed milk is undoubtedly not as susceptible to deterioration as raw milk, " because if evaporated to the proper density, the bacteria can not grow, as food can not be absorbed by them." EFFECT OF SANITARY KESTEICTIONS ON DEMAND FOR PREPARED MILKS. It has been suggested that insistence upon additional requirements concerning milk, such as the tuberculin test, maintenance of low temperatures, etc., would lead to the use of prepared milks and other substitutes for raw or pasteurized milk. The committee has endeav- ored to elicit information from as many sources as possible tend- ing to prove or disprove this assertion. There has been an appg^rent reluctance on the part of most of the health officers and experts consulted by the committee to vouchsafe an opinion on this point, and while approximately 30 per cent of those approached are strong in the belief that the public will not be compelled to resort to such preparations, one authority believes that there would be a tendency in that direction, while another inclines to the assumption that such substitutes would be very considerably used. The Bureau of Animal Industry ventures the assertion that, if the requirements be gradually introduced, there would probably be no influence on the market in this direction, but that sudden enforce- ment might make it necessary for a limited time to use prepared milks. The health officer of Atlanta, Ga., states that no such results have transpired in that city, but that on the other hand bad milk certainly leads to this expedient. The health officer of Lynchburg, Va., takes an optimistic view of the situation, and refers to the fact that judicious inspection in that city has resulted in an extremely enlarged demand for fresh milk, the consumption being almost thrice what it was some time ago. The health officer of Topeka, Kans., observes that people naturally prefer the fresh article when they can get it. 82444°— S. Poc. 863, 6X-3 9 130 THE MILK SITUATION IN" THE DISTRICT OF COLUMBIA. PKICE OF PREPARED MILKS. The committee has deemed it important in weighing the probable effect of promulgating regulations for the further improvement of our milk supply, not only to arrive at some concrete idea of the prob- able extent of consequent utilization of prepared milks as substitutes for the natural product, but also to inquire into their ingredients and to ascertain the prices commanded by these preparations when diluted for use, for comparison with the cost of the raw or pasteurized product of corresponding volume. There is a somewhat general impression prevailing among persons consulted by the committee that the prepared milks are higher in price than the current market rates for raw or pasteurized milk, and that they would probably offer no inducement to buyers in competition with the fresh product. Investigations made by the Boston Board of Health show that if condensed milk is diluted with only enough water to constitute milk of the Massachusetts standard, the cost exceeds the price of ordinary milk and in some instances equals the price of inspected milk and exceeds that of some brands of certified milk. The conclusion is reached by the Bureau of Animal Industry that condensed milk can not be employed economically where whole milk is procurable. The health officer of Richmond, Va., is authority for the statement that prepared milks are much higher in cost than raw milk at 10 cents per quart, the prevailing Richmond price, Borden's Condensed Milk Co. says that on the average, when prepared milks are increased to equal volume with whole milk and contain the same ratio of solids, their cost is approximately the same and in some cases lower. CONCENTKATED MILK. What is known as " concentrated " milk, supplied by the White Cross Milk Co. to the people of Washington, is derived by placing normal milk in a concentrator maintained at a temperature not ex- ceeding 140° F. A blast of filtered air is then forced through the milk with great velocity for a period of about three hours, during which period the harmful bacteria are destroyed and the greater part of the water is carried off by evaporation, the quantity of milk being reduced to one- fourth of its original volume. This process not only removes the pathogenic germs from the milk, but preserves its natu- ral flavor, and the condensation makes it a much less favorable medium for subsequent contamination and for the proliferation of pathogenic microorganisms. The rather recent commercial practice of concentrating milk in this manner has the advantage of reducing the cost of transportation on account of the reduced bulk, enables a single dairy wagon to quadruple its capacity, and serves to preserve the milk for a longer period than is possible with raw milk, and in other respects makes it practicable to supply this important product at substantially the same retail price as demanded for raw milk of ordinary quality. Concentrated milk is especially suited for ship- ment into distant lands where raw milk is unobtainable, and for use on steamers at sea. The fact that it lends itself readily to dilution makes it useful also, when slightly thinned, as a substitute for cream in coffee. Another advantage resulting from the introduction of this THE MILK SITUATION" IN THE DISTRICT OF COLUMBIA. 131 process is the feasibilitjr of locating condensers at points too remote from centers of population to make the shipment of sweet raw milk mechanically possible, and thus reducing it to a state in which it may be transported for longer distances and compete in price with the raw product supplied by dairy farms in proximity to the cities, the smaller bulk compensating for the longer distance of trans- portation. POWDERED MILKS. Whole and skim milk is being reduced to powdered form for use by bakers, confectioners, and others, its reduction to this form making it especially adaptable to preservation without deterioration for very considerable periods of time. It may be stated in behalf of the skimmed product that, while it lacks the amount of butter fat and when powdered is in many cases totally deficient in this component of whole milk, it possesses, with imperceptibly diminished degree, the other ingredients of whole milk which are essential factors in its nutrient value. While what are known as powdered milks are prin- cipally restricted to the evaporated product relieved of its butter fat (though certain makes of powdered milk are represented to contain a due proportion of butter fat as well as the other constituents of whole milk, except, of course, the water, which has been removed), their utilization for economic purposes is fast being realized, and it may be claimed strongly in their favor that they are in many respects free from contamination, which is an ever-present source of danger when whole milk or milk in its raw state in liquid form is handled, especially in bulk. It is believed that the powdered product is destined eventually to fulfill a demand on the part of the poorer classes, who are enabled to procure milk in this form, when diluted volume for volume, at a cheaper cost than otherwise. SKIM (skimmed) or SEPARATED MILK. Skim milk is defined in the Standards of Purity for Food Prod- ucts,^ issued by Secretary of Agriculture in pursuance of authority given by Congress in the food and drugs act of June 30, 1906, as follows : Skim milk is milk from which a part or all of the cream has been removed and contains not less than 9.25 per cent of milk solids. Condensed skim milk is defined in the Standards of Purity for Food Products ^ as " milk from which a considerable portion of water has been evaporated." It is doubtless to be understood under this definition that the milk has been partially or wholly relieved of its cream before condensing. CONSmERABLE ECONOMIC VALUE OF SKIM MILK. There is much popular misapprehension as to the efficaciousness of skim milk, which has for years past enjoyed a very considerable degree of opprobrium on account of its being offered for sale as whole milk, thus defrauding the purchaser of the full amount of butter fat, * Circular No, 19, Bureau of Chemistry, U. g. Department o? Agriculture, 132 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. removed in the separation of cream, to which he is entitled. It is a matter of interesting information, however, that skim milk is begin- ning to play an important part in the economic latter-day consump- tion of milk. There are many farms throughout the vast territory of the United States situated so remote from the centers of population that the transportation of milk derived from their herds in its raw state to available markets is utterly impracticable, the cost of trans- portation and the length of time necessarily consumed en route making it impossible to compete with the product of farms more advantageously located geographically with reference to commercial centers. For this reason an enormous amount of raw milk, after the cream has been separated for butter making, has been fed to ho^s and other farm animals. This vast waste product, relatively speaking, is now, by the process of aeration, being partially condensed or pow- dered, making it profitable, on account of its reduced bulk and better keeping qualities, for transportation to market. In favor of skim milk it may be supplemented that a much larger number of bacteria are found in cream than in the bottom milk, one sample of milk examined containing 500 times as many bacteria in the cream. When milk is. placed in the generally used centrifugal separator, the great mass of bacteria rise with the cream, a lesser number being carried down with the sediment. The intermediate milk, therefore, contains markedly fewer bacteria per cubic centimeter than the cream or sediment layers. XII. Milk Products. A discussion of the local milk situation would be incomplete with- out an allusion to the conditions affecting milk products, namely, butter, buttermilk, cheese, ice cream, and oleomargarine. It has been conclusively demonstrated that pathogenic organisms persist in ,these products with virulence, often for many months, and that it is of the utmost importance that milk employed in the preparation of these products be clean and wholesome, and meet in every particular the requirements demanded of milk in its natural state. Tubercle bacilli concealed in butter, buttermilk, and other dairy products are dis- tributed throughout these products in such a way as to insure their ingestion by the consumer wherever the sale of milk from tuberculous cows is permitted. CREAM. The same conditions affecting milk apply, generally speaking, to cream, which is merely cow's milk with an excessive amount of fat, the other ingredients being substantially the same in character and amount as in raw milk. Cream is defined in the Standards of Purity for Food Products,^ issued by the Secretary of Agriculture in pursuance of authority given by Congress in the food and drugs act of June 30, 1906, as follows : Cream is that portion of milli, rich in milk fat, which rises to the surface of milk on standing, or is separated from it by centrifugal force, is fresh and clean, and contains not less than 18 per cent of milk fat. J CU'Cular No, ].9, Bureau of Chemistry, U, S. Department of Agriculture, THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 133 Evaporated or clotted cream is defined in the Standards of Purity for Food Products ^ as " Cream from which a considerable portion of water has been evaporated." This product is often referred to, locally at least, as " double cream." ICE CREAM. The conditions under which ice cream is manufactured in many instances in the District of Columbia are not at all satisfactory, and radical improvements are necessary to insure purity and freedom from contamination. Many cases of violent poisoning are due to insanitary conditions surrounding the ice-cream factory, to the storage of the product for an improper length of time, and to the lack of care in keeping the utensils and receptacles cleanly and not sterilizing them to destroy bacterial life. The danger of ptomaine poisoning from cream and ice cream may be entirely obviated by using a wholesome raw product, manufacturing it in perfectly clean surroundings, and disposing of it within a reasonable length of time after manufacture. Cream and ice cream sold in the District have been shown by examination to contain a number of bacteria far in excess of what should be found in such products derived from pure, uncontaminated, fresh materials. Thickeners do not appear to be generally used in the production of ice cream in the District. The sooner ice cream is consumed after making the better, and the chief objection to the use of thickeners is that it enables the ice cream to be kept for a longer period of time than is healthful. It also aids in the expansion of the volume of cream to proportions entirely beyond the actual amount of nourish- ment represented. Inasmuch as ice cream is sold exclusively by vol- ume and not by weight, this expansion can only be regarded as a deception practiced upon the consumer. The use of such substances in the manufacture of ice cream is not a commercial necessity, and if permitted, thickeners should be restricted to materials which are wholesome and unobjectionable, and the fact that they have been employed should be required to be plainly stated on the label of the package or other receptacle in which ice cream is sold. Since, furthermore, ice cream is definitely understood by the public to contain certain ingredients, and is prescribed frequently by physi- cians as a diet for invalids and convalescents, the term should be reserved solely for the frozen product composed of pure, fresh cream, sugar, and flavor. It should be required, moreover, that ice cream represent a definite percentage of butter fat corresponding to the established standards, 12 per cent being recommended for ice cream flavored with fruits, and 14 per cent as requisite for the vanilla type of ice cream. It is believed that the specification of these requirements to con- trol the manufacture of ice cream for sale and consumption in the District of Columbia would materially assist in conserving the health of the public from injury from this source of infection.- 1 Circular No. 19, Bureau of Chemistry, TJ. S. Department of Agriculture. * The committee is indebted for this information to the Interesting and comprehensive chapter on " Ice cream," by Dr. Harvey W. Wiley, Chief of the Bureau of Chemistry, U. S. Department of Agriculture, in Bulletin No 56 of the Hygienic Laboratory, Public Healtb and Marine-Hospital Service, p. 251. 134 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. BUTTERMILK. Buttermilk is defined in the Standards of Purity for Food Prod- ucts/ issued by the Secretary of Agriculture in pursuance of authority by Congress in the food and drugs act of June 30, 1906, as " The product that remains when butter is removed from milk or cream in the process of churning." NECESSITY FOR MAINTAINING MILK PRODUCTS AT LOW TEMPERATURES. In response to an inquiry addressed to the Bureau of Animal Industry as to whether there is reason for requiring that butter, cheese, and other milk products be maintained at low temperatures, the committee is informed that while low temperatures retard and inhibit the growth and multiplication of pathogenic germs they can not be relied upon to destroy such germs, and the requirement that dairy products be held at low temperatures would therefore not remove the danger. The bureau recommends the pasteurization of cream or milk before making into butter or cheese as the best method of accomplishing the object desired. REMEDIAL LEGISLATION RECOMMENDED. Reference is made elsewhere in this report (p. 76) to the resolutions unanimously adopted by the board of directors of the local Associa- tion for the Prevention of Tuberculosis on December 27, 1910 (Ap- pendix AE ) , reciting that it has been shown by indisputable evidence that typhoid fever and other diseases are traceable to contaminated dairy products, and urging that Congress investigate the relation of dairy products to the public health with a view to the enactment of remedial legislation. XIII. Summary — Recommendations. The recommendations of the committee may be summarized as follows : 1. That unless washing, bottling, and capping machines, and other apparatus and the maintenance of a separate salesroom be uniformly insisted upon, no demerit be recorded by the health department against the small dealer not possessing these appurtenances. 2. That the requirement of concrete floors (over which a movable wooden or other covering may be placed) be continued in force. 3. That specific approval be secured from Congress for proposed changes of large importance in the regulations affecting our local milk industry. 4. That Congress provide a suitable increase in the number of in- spectors to fully meet the requirements of the milk-inspection service. That the regulations issued by the District Commissioners on April 21, 1903, prescribing under penalty that any person in the District of Columbia who receives milk or cream tor sale shall, immediately after emptying the receptacle in which such milk or cream has been received, thoroughly rinse such receptacle so as to » Circular No. 19, Bureau of Chemistry, U. S. Department of AgricuUure. THE MILK SITUATION JN THE DISTRICT OF COLUMBIA. 135 free the same from all remnants of milk and of cream, or cause such receptacle to be so rinsed, be amended by eliminating the words " for sale," so as to extend this requirement to consumers and all other persons, as well as to dealers. 5. That all cases of communicable disease among dairy farmers and their assistants, outside the District of Columbia furnishing milk to the Washington market, be required to be reported to the District health department. (The act of March 2, 1895, already authorizes the health officer to suspend or revoke permits for shipping into the District milk from dairy farms exposed to infection by diphtheria, scarlet fever, tuberculosis, typhoid fever, and other infectious and contagious diseases.) 6. That the health department continue its method of exacting a reasonable standard as opposed to an ideal standard for rating dairies and dairy farms. 7. That no investigation be authorized of the administration of the District health department as proposed by the Dairymen's Associa- tion, the department being, in the view of the committee, singularly free from conditions demanding such an investigation. 8. That the classification of milk suggested by Dr. A. D. Melvin and recommended by the Washington milk conference of 1907 be approved for the District of Columbia by specific legislation. 9. That the additional recommendations of the Washington milk conference of 1907 be approved for the District of Columbia, except that regulations intended to safeguard the District milk supply, if of large importance, be specifically authorized by Congress; that the necessary plant or plants for pasteurizing the local milk supply be not maintained by the District government; that all milk not "cer- tified" or "inspected," intended for local consumption, be required to be pasteurized ; that in pasteurization milk be required to be heated to a temperature of 145° F. for 20 minutes or 140° F. for 30 minutes; that milk, even from tuberculin-tested cows, unless " certified " or " inspected," ' be compulsorily subjected to pasteurization; that the health department be required to publish periodically, though not daily, the ratings of dairies and dairy farms; and that parents and guardians be urged to use only " certified " milk or properly pasteur- ized or " modified " milk as a food for infants, at least under the age of 3 years. It is believed that the requirements specified will dis- pense with the necessity of boiling milk to be consumed. 10. That all milk supplied for the use of hospitals, foundling asy- lums, and other institutions within the District of Columbia sup- ported wholly or in part by public funds, be required to comply with the classification recommended by the Washington milk conference of 1907, subject to the exceptions noted by this committee under recom- mendation 9. It is understood that the recent order of the District Commissioners under date of November 8, 1910, specifies that milk for such institutions be either properly pasteurized or derived from tuberculin-tested herds. The committee recommends that the Dis- trict Commissioners issue promptly an amendment to this order specifying that raw milk even from tuberculin-tested herds be re- quired to be pasteurized (unless " certified " or " inspected " in con- formity with the provisions of the classification of the Washington milk conference of 1907) , since the tuberculin test insures only against tuberculosis. 136 THE MILK SITUATION" IN THE DISTRICT OF COLUMBIA. 11. That favorable action be had on Senate bill 4986, introduced by Mr. Gallinger on January 10, 1910, authorizing, among its provi- sions, the commissioners to promulgate and amend from time to time regulations governing the production and sale of milk, cream, and ice cream in the District of Columbia. As above recommended, however, changes of large importance in the regulations governing the milk supply should, in the judgment of the committee, be the subject of specific legislation by Congress. 12. That the action of the Department of Agriculture in compelling all milk furnished to employees at the several buildings under the control of the department within the District to Columbia to com- ply with the classification recommended by the Washington milk conference as defined in Circular No. 114 of the Bureau of Animal Industry be extended to embrace all executive departments and independent establishments of the Government located at Wash- ington. 13. That a similar order be issued by the District Commissioners covering milk furnished to employees in buildings under the control of the District government. That the suggestions' 21 in number, by Mr. E. H. Webster, for improved sanitary conditions on dairy farms, set forth in Appendix O of this report, be adopted generally in separate jurisdictions throughout the United States. That the current regulations of the District health department governing dairies and dairy farms be periodically printed on muslin or similar inexpensive fabric and required by regulation to be kept conspicuously posted in all dairies and barns from which milk is supplied for distribution in the District of Columbia. 14. That legislation be enacted by Congress requiring all tuberculin manufactured in one State and offered for sale in another to measure up to a prescribed standard. 16. That official applications of the tuberculin test to farm animals be restricted to authorized veterinarians or other skilled persons under the supervision of the Federal (xovernment, so far as this coincides with the powers gxanted by the Federal Constitution for the regula- tion of interstate commerce. 16. That any attempts to adulterate or otherwise impair the efficiency of tuberculin as a diagnostic agent be severely punished, and that such punishment extend with equal force to persons con- victed of inoculating cattle with the intent and purpose of rendering them immune to reaction under the tuberculin test. IT. That every druggist or other person dispensing tuberculin be compelled to register each sale and maintain a detailed record of all such Iransactions for the scrutiny of supervising officials of Federal and State governments. 18. That every veterinarian or other practitioner applying the tuberculin test be compelled by law to make an accurate report thereof to the duly constituted authority, tagging or otherwise identifying each animal tested so as to enable an intelligent observance of the provisions of the statutes and ordinances governing such matters. 19. That, as recommended by the International Commission on the Control of Bo\^ne Tuberculosis, all contact between tuberculous and healthy cattle and between healthy cattle and stables, cars, etc., which may contain live tubercle bacilli be prevented, live-stock shippers THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 137 being enjoined to see that all cars used in the shipment of cattle are thoroughly cleansed and disinfected before use. 20. That the sale or exchange of animals affected with tuberculosis, except for immediate slaughter or for breeding purposes under official supervision, be inhibited under penalty of law. 21. That all animals exposed to tuberculosis be retested at intervals of six months to one year. 22. That the tuberculin test be not applied to any animal having a temperature higher than normal. 23. That any animal having given one distinct reaction to tuber- culin be thereafter regarded as tuberculous, though if the disease be arrested, as evidenced by later successful withstanding of the tuber- culin test, such fact be taken into account. 24. That a positive reaction to tuberculin in any properly conducted test, official or otherwise, in any animal in any herd, shall be con- sidered evidence sufficient upon which to declare the herd to be in- fected until such time as a subsequent test or elimination of animals shown to be diseased shall demonstrate the herd to be free from tuberculosis. 25. That owners and veterinarians be compelled by law to report the existence of tuberculosis in a herd, whether such information result from clinical examination or from the tuberculin test. 26. That some system of marking, for purpose of identification, be adoj^tecl with regard to all cattle 3 years old or over shipped for slaughter. 27. That, except when purchases are made from disease-free herds tested by a properly qualified individual, persons buying for breeding purposes or milk production limit their purchases to animals suc- cessfully withstanding the tuberculin test, and that in order to facili- tate the compliance with this suggestion official authorities adopt such regulations as will prevent the entry into their respective territories of cattle for breeding purjjoses or milk production unless accompanied by satisfactory tuberculin-test charts. 28. That, with a view to securing uniformity in legislation regard- ing the control and eradication of bovine tuberculosis, the laws of the United States, Canada, and other American countries governing the admission of animals from without their borders be made stringent and as uniform as possible, as well as those regulating the interstate and interprovincial movement of cattle. 29. That in order to make cattle as resistant as possible to infec- tion with tuberculosis, they be stabled in clean, disinfected, and properly ventilated and lighted barns, giving them abundant clean water, nutritious food, and a sufficient amount of daily exercise in the open air; and that such other conditions be provided as are well known to contribute to the health of animals, including the twice daily removal of manure from stables and the installation of water- tight floors and proper drainage. 30. That the expense of applying the tuberculin test, when com- pulsorily made, devolve upon the Government (State or municipal). That in accordance with the " half-and-half " principle of appropri- ating for the needs of the District Government, the cost, so far as the testing of cattle located within the District boundaries supplying milk to the Washington market is concerned, be provided one-half 138 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. from the Federal Treasury and one-half from the revenues of the District of Columbia. 31. That, in the judgment of the committee, the scale of com- pensation to owners for cattle condemned as a result of the tuber- culin test, set forth in the order of the District Commissioners dated November 26, 1909, " For the suppression and prevention of tuber- culosis in cattle," v^hich scheme of compensation coincides with the views of the officials of the United States Department of Agricul- ture, be approved as best adapted to insure justice to the herd owner. 32. While the committee unqualifiedly favors the application of the tuberculin test, it especially recommends that the test be applied gradually, the herds supplying milk to the District being inspected seriatim with such gradualness as may be intelligently calculated to enable the replacement of infected animals with healthy ones, thus avoiding a possible shortage in the District milk supply. For this purpose it is proposed by the committee that a period of approxi- mately two years, or say January 1, 1913, might appropriately and advantageously be fixed for the introduction of the test compulsorily among herds supplying milk for the Washington market. 33. That milk, from the time of cooling immediately after derived from the cow, until actual delivery at the residence of the consumer, be required to be maintained at a temperature not exceeding 50° F. (provided it be feasible to secure the necessary refrigerator-car serv- ice for transportation from the farm to the city). This requirement, in the judgment of the committee, should be gradually put into force. The maintenance of a temperature not exceeding 50° F. should be required, furthermore, in the handling of cream, and of milk and cream used in the manufacture of butter, cheese, and ice cream. 34. That the establishment of ice houses on dairy farms for the storage of a sufficient supply to maintain, during the warm season from April 1 (or earlier) to November 1 (or later in exceptional instances of mild weather), milk at a temperature not exceeding 50° F., and the installation of an adequate service of refrigerator cars or effectually jacketed cans necessary to maintain a temperature continuously below 50° F., be insisted upon, provided it be deter- mined after detailed examination of items of expense that refriger- ator-car service is a rational economic possibility. 35. That to meet the restrictions proposed in recommendation num- bered 33, milk be required to be kept refrigerated while on delivery wagons. 36. That the pasteurization of all milk, not " certified " or " in- spected " in conformance with the requirements of the classification recommended by the Washington milk conference of 1907, be insisted upon, and that for this purpose it be required that an exposure of the milk uniformly at a temperature of 140° F. (60° C.) continu- ously for a period of 30 minutes (or 145° F. for a period of 20 minutes) be enforced, with the understanding that the periods of 30 or 20 minutes referred to shall not include the interval during which the milk is attaining the specified temperature. That com- pulsory pasteurization as proposed be arranged to take effect on January 1, 1913. 37. That what is known as " flash " or " continuous " pasteuriza- tion be not permitted, since it is mechanically impossible to subject THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 139 the milk uniformly to the requisite amount of heat during the short interval generally determined upon for this method of pasteuriza- tion. 38. That a provision of law be enacted and rigidly enforced pro- hibiting the sale of milk, especially in retail establishments, left over from the previous day's delivery. 39. That in addition to the compulsory pasteurization of milk, not " certified " or " inspected " in accordance with the specifications of the Washington milk conference of 1907, the tuberculin test and the proposed specification of a maximum bacterial content and a maxi- mum temperature of milk offered for sale in the District of Columbia be also insisted upon. 40. That pasteurization be required to be done under permit issued by the District health department, and that the milk be at once cooled and placed in sealed sterilized containers and delivered sealed, plainly marked " Pasteurized," with an indication on the label of the date and hour when the pasteurization was completed; furthermore, that pasteurized milk be delivered to the consumer within 24 hours after pasteurization. 41. That unless the provision of an adequate refrigerator-car service proves impracticable, making it impossible to maintain milk in transit at 50° F. or less, the plant or plants for pasteurizing the District milk supply (with the exception of one already established at considerable expense by the White Cross Milk Co. at Frederick, Md., and possibly others already in operation in connection with the local milk supply) be required to be located within the limits of the District of Columbia. 42. That the contemplated pasteurizing plant or plants be con- ducted under private auspices and not maintained by the District government, the establishment of such plants under municipal owner- ship being, in the opinion of the committee, neither necessary nor desirable. 43. That a general milk delivery service be (H-ganized by local dairymen with a view to eliminating unnecessary expenditure in delivering milk owing to duplication of capital invested and labor involved. 44. That, for the present at least, 500,000 be agreed upon as the maximum number of bacteria allowable for raw milk (not " certi- fied ") , 100,000 for pasteurized milk, and 10,000 for " certified " milk offered for sale in the District of Columbia. 45. That in the judgment of the committee a high bacterial con- tent, especially if repeated in the milk from a given farm, unques- tionably indicates insanitary conditions — either uncleanliness on the farm, maintenance at a temperature above 50° F., staleness of the milk, or a diseased condition of the cow's udder from which the milk furnished is partially derived. 46. That milk be not permitted to be sold in bulk at grocery or similar retail establishments; that the public be admonished not to buy " bulk " milk from a retail store (not a dairy) , and that milk for babies' use be not purchased from grocery or other establishments where it may possibly have been kept over from the day before. 47. That the furnishing of pasteurized and modified milk for in- fant feeding can probably be accomplished at much less expense 140 THE MILK SITUATION IK THE DISTRICT OF COLUMBIA. through existing commercial agencies than by the maintenance of the local Straus Pasteurizing Laboratory. 48. That in the event that the local Straus Infants' Milk Depot be not continued as a charity, a fund be liberally supported by the pub- lic, perhaps aided by congressional appropriations, from which modi- fied milk or other proper food for infants among the indigent classes may be furnished. Such fund could perhaps be best administered in connection with existing agencies such as the diet kitchen, the Citi- zen's Relief Association, the Associated Charities, and the Instruc- tive Visiting Nurse Society. 49. That in the judgment of the committee it is better to purchase milk already pasteurized under competent supervision from infants' milk depots or from properly equipped commercial establishments, than to attempt its pasteurization at home in apparatus of which several economical patterns are obtainable on the market. 50. That every encouragement should be extended by the residents of Washington to the Instructive Visiting Nurse Society, which is, through giving practical instructions to parents and others at the home of the infant concerning its proper feeding, bathing, clothing, etc., accomplishing marvelous results in reducing infant mortality in the District of Columbia, and that every facility be offered for the instruction of mothers in caring for their infants. 51. That the excellent work being done by what are known as " settlement houses " in educating the indigent classes to a proper recognition of the value of appropriate food for infants' use, and in otherwise encouraging the proper treatment and development of in- fants of the dependent poor, be liberally assisted by our citizens. 52. That mothers, regardless of their financial or social status, be encouraged in every possible way to nurse their infants, it having been conclusively proved by extended series of careful investigations, that the mortality among bottle-fed infants is vastly greater than among those that are breast fed. 53. That when breast feeding is clearly impossible, however, a ful- some supply of pure coav's milk, modified to meet the special needs of the infant, be rendered available for both rich and poor, and that mothers be instructed in the same connection regarding the special requirements necessary to successful artificial feeding. 53-|. That the President of the United States be requested to direct the Department of Agriculture and the Bureau of Public Health and Marine-Hospital Service of the Treasury Department in cooperation, to investigate the relative value of raw and pasteurized milk for in- fant feeding, with a view to arriving at a finally authoritative settle- ment of this controversial subject among sanitarians and physicians generally. It is believed that the solution of this question as regards infant feeding would also have an important influence in determining the relative merits of raw and pasteurized milk for adult con- sumption. 54. That the precautions concerning the care of milk in the home, suggested on pages 116 to 118, inclusive, of this report, be diligently observed by consumers of milk. 55. That milk intended for use in preparing milk products, namely, butter, buttermilk, cheese, ice cream, and oleomargarine, be required to comply with the stipulations herein specified for milk in its raw or pasteurized state. THE MILK SITUATION" IIST THE DISTRICT OF COLUMBIA. 141 56. That , the designation " ice cream " be reserved solely for the frozen product composed of pure, fresh cream, sugar, and a flavor ; that it represent a definite percentage of butter fat corresponding to the established standards, namely, 12 per cent for ice cream fla- vored with fruits, and 14 per cent for the vanilla type of ice cream; and that it be required to be manufactured in cleanly, sanitary sur- roundings and disposed of within a reasonable length of time after manufacture; furthermore, that the use of thickeners, if permitted, be restricted to materials which are wholesome and unobjectionable, and the fact that they have been employed be required to be plainly stated on the label of the package or other receptacle in which ice cream is sold. 57. That in order to bring the public to a proper appreciation of the importance of clean, wholesome milk, and the necessity for intelligent care in its treatment in the household, a brief circular be prepared and distributed by the health department containing suggestions for the proper care of milk in the home, alon^ the lines indicated in the committee's recommendations on this subject. 58. That this report, if approved by the chamber, be transmitted to the Senate and House of Eepresentatives with a request that it be printed and that its recommendations, so far as applicable to the District of Columbia and likewise so far as pertinent to the Federal powers over food commodities entering into interstate commerce, be embodied in suitable legislation; that a copy of the report be for- warded to the District Commissioners ; and that the publishers of the Washington newspapers be appealed to to promote as fully as prac- ticable the dissemination among the local public of infomiation con- cerning sanitary milk production and its preponderant advantages to the community. 59. That a special committee be appointed by the chamber to urge before the Commissioners of the District and before the committees of Congress the expediency of the proposed legislation. Respectfully submitted. J. Louis Willige, Ghairman. Geo. W. White. Benj. W. Guy. T. C. DULIN. Wm. D. Hoover, January 30, 1911. APPENDIXES. APPENDIX A. SERIES OF QUESTIONS ADDRESSED BY THE SPECIAL COMMITTEE OF THE WASHINGTON CHAMBER OF COMMERCE TO HEALTH OFFICERS, ETC., ELICITING INFORMATION CONCERNING THE SUBJECT OF ITS INQUIRY.

Question 1. — What advantages in your judgment xoill result from the enforce- ment of the tuberculin test? ANSWERS. The principal advantage resulting from the enforcement of the tuberculin test is the elimination of the germs of tuberculosis from milk and tjie conse- quent elimination of a great source of danger to the health of consumers, especially infants. This test can also be used in a rational way to eradicate tuberculosis from cattle with good economic results to the live-stock industry. (Chief Bureau of Animal Industry.) Gradual eradication of tuberculosis in dairy cattle, (Surgeon General U. S. Army.) It will give us an accurate estimate of the amount of tuberculosis present in a given herd of cattle. (Surgeon General U. S. Navy.) The enforcement of the tuberculin test would reduce the amount of tuber- culosis among dairy cattle, and free the milk supply from tubercle bacilli, with the probable result that the incidence of tuberculosis among hogs fed on creamery skimmed milk would be reduced and the incidence of infection with the bovine tubercle bacilli among human beings would be practically elimi- nated. (Surgeon General Public Health and Marine-Hospital Service.) The removal of the greater part of tuberculosis, from the herds and the re- moval of all advanced cases. Animals should only be added to herds after reliable test. (Dr. William H. Parks, New York, N. Y.) Eventual eradication of bovine tuberculosis. (Dr. Henry L. Coit, Newark, N. J.) 1 No response received. THE MILK SITUATION" IN THE DISTRICT OF COLUMBIA. 149 A marked diminution in infant mortality. (Dr. R. G. Freeman, New Yorli, N. Y.) Eradication of tuberculous cows from dairy herds, and consequent protection of children against bovine infection. (Dr. M. P. Ravenel, Madison, Wis.) Decrease in tuberculosis, human and bovine. (Dr. C. E. A. Winslow, New York, N Y.) Establishing a dairy herd free from tuberculosis. Removing one of the most important sources of infection from tuberculosis to human beings. Of great advantage to owners of herds from an economic standpoint, by increasing the health and efficiency of the individual animals, it taking more food stuff to produce results in a tuberculous animal than one which is not tuberculous. This is true especially where glands of the intestinal tract are involved. In coun- tries in Europe, where tuberculosis is prevalent, I have found a large per cent of nonbreeding heifers, in herds, containing a high per cent of tuberculous animals. (Dr. T. A. Geddes, Kensington, Md.) Elimination of tubercular cattle. (Health officer Ailn Arbor, Mich.) We have been investigating the matter of tuberculosis in our dairies for the post two or three years, and are not yet prepared to give definite answers to these questions. (Health officer Atlanta, Ga.) Besides lessening the number of cases of tuberculosis, we would obtain better sanitary conditions for the cows. (Health officer Baltimore, Md.) Safeguarding of public health from the danger of infection from bovine tuber- culosis. Also the eradication of tuberculosis from dairy animals. (Health officer Birmingham, Ala.) Sale of less milk from tuberculous cows. (Health officer Bismarck, N. Dak.) Eradication of bovine tuberculosis and consequent diminution of possibility of infection of people using raw milk. (Health officer Cleveland, Ohio.) The prevention of the conveyance of bovine tuberculosis to man; (2) the economic interest of the dairyman in preserving the health of cattle. (Health officer Columbus, Ohio.) Decrease in tubercle infected milk. (Health officer Detroit, Mich.) It will eventually rid the herd of tuberculosis with all the train of benefits that follow. Its reaction on the human health will be such as to be expected from the use of milk from healthy instead of diseased cattle. (State board of health, Fla.) Elimination of some cases of tuberculosis and the discovery of other dis- eases as a result of the inspection. (Health officer Jacksonville, Fla.) Eliminate all diseased cows from herd. (Health officer Kansas City, Mo.) A great advantage, if you can enforce it. It is hard to enforce and should be introduced gradualy, say by publishing in monthly reports the dairies that are tested. (Health officer Lynchburg, Va.) Less human tuberculosis among children, especially of the surgical forms. Better general health of the herds. Less loss to the farmer after he once has a tuberculosis-free herd. (Health officer Montclair, N. J.) The removal of diseased cattle from market. The removal of tuberculosis germs from milk, and giving us better meat for table use. (Health officer Portland, Oreg.) Milk from diseased cattle would be reduced to a minimum. (Health officer Providence, R. I.) If enforced fully it will necessarily exclude all milk from tuberculous cows. (Health officer Richmond, Va.) The removal of open tuberculosis and the resultant clearing up of cows and stables that always follows the test. (Health officer Rochester, N. Y.) A very considerable advantage. Probably lessening tuberculosis in the human. (Health officer Seattle, Wash.) The saving of herds and the production of safer milk. (Health officer Syra- cuse, N. Y.) Elimination of danger of infection of man by bovine tuberculosis. Aid in education of the people to greater caution among themselves in respect to human tuberculosis. (Health officer Topeka, Kans.) Would remove to a very great extent the danger of tuberculous infection in milk and would tend toward a more careful handling of milk generally. (Straus Laboratory, Washington, D. C.) I think the disadvantage would more than countei'act the advantage. (John Thomas, Ednor, Md., president Milk Producers' Association.) None; on the contrary, milk consumers will be compelled to pay an exorbi- tant price for milk. (Sharon Dairy, District of Columbia.) 150 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. We do not approve of the enforcement of the tuberculin test for many reasons, some of which will appear more fully in our answers to subsequent questions. Our first reason for disapproval of the enforcement of the tuberculin test is that the scientific world has not yet fully accepted the belief that bovine tuber- culosis is transmissible to human beings. Exhaustive examinations have been conducted upon this subject, both abroad and in our country, for several years. It is claimed by scientists of the highest standing that no primary case of tuber- culosis from purely bovine sources has been conclusively demonstrated. Turn- ing to the facts produced by those who claim to have discovered the bovine bacillus in human beings, we believe that we can sum up the result of their investigations in the statement that those who claim that human beings are liable to contract tuberculosis from bovine sources through the ingestion of milk admit that such cases are very limited in number; and none are claimed to have been definitely proved where the contagion has affected a child over 5 years old, and so small a number of infants under 5 years as to be negligible. Second. The enforcement of the tuberculin test and the slaughter of react- ing cows would necessarily increase the price of milk. The immediate results of this increase of price would be to deprive many people of one of their chief staples of food and the probable loss of human lives among children who would be apt to die as the result of inanition. It is possible that, from an economic point of view, the country will some day come to the enforcement of the tuberculin test throughout the whole country, but in the present state of the dairy business a general enforcement of that test and the slaughter of the reacting cows would produce, first, a great financial injury to the dairy business, and, second and more serious, a loss to the people of the country in depriving a great majority of a large portion of their milk supply. When the time has arrived for the enforcement of the test throughout the country we believe that if properly and honestly enforced it will produce economic results in helping to protect the dairymen from the loss which now follows one of the contagious diseases to which animals are liable. (Bor- den's Condensed Milk Co., New York, N. Y.) Properly applied, the tuberculin test would eradicate tuberculosis from dairy herds and most probably cause a marked reduction of this disease among chil- dren. (Walker-Gordon Laboratory.) Decrease of tuberculosis. (Dr. V. C. Vaughan, Ann Arbor, Mich.) A higher quality of milk and feeling of security in the community that one danger is largely overcome. (Dr. S. C. Prescott, Boston, Mass.) It would give milk free from tubercle bacilli. Ultimate eradication of tuber- culosis from dairy cattle. (Health officer Los Angeles, Cal.) None at this time. (J. M. Houston, White Cross Milk Co., Washington, D. C.) Assist in prevention of spread of bovine tuberculosis. (Health officer San Francisco, Cal.) It would create more demand for raw milk and lessen the need for pasteur- ized milk ; also less demand for pasteurized milk would necessitate cleaner milk. (Health officer St. Joseph, Mo.) Ultimately the eradication of tuberculosis from cattle. (Health officer Wheel- ing, W. Va.) It will protect the producer from severe losses from tuberculosis in his herd that must necessarily follow without the test. It will protect children from infection. (Dr. C. J. Marshall, University of Pennsylvania, Philadelphia, Pa.) To allay the fears of the milk consumer, regarding transmission to humans. (Health officer Scranton, Pa.) Question 2. — To what extent is the tuberculin test reliablef ANSWERS. The tuberculin test applied by a competent person with properly prepared tuberculin is exceedingly reliable in the detection of tuberculosis and is by far the most reliable agent known for this purpose. This test makes it pos- sible to detect tuberculosis in cattle at an early stage when the disease could not be discovered in the living animals by other means. The few generalized and advanced cases that do not react to tuberculin can be easily detected by visual examination. The results of tests made by State and Federal officers with tuberculin prepared by the Bureau of Animal Industry covering a period of over 15 years show that the lesions of tuberculosis were demonstrated in 98.39 per cent of reacting cattle which were slaughtered. In the recent work of test- THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 151 ing all cattle in the District of Columbia 321 reacting animals were slaughtered and lesions of tuberculosis were found on post-mortem examination in all but 5, the percentage of accuracy being 9S.44. Laboratory experiments were made by the Bureau of Animal Industry during the past year in testing by microscopic examination and animal inoculation the glands of cattle which had reacted to the tuberculin test, but in which lesions were not found by ordinary post- mortem examination ; and in more than half of the cases tubercle bacilli were positively identified. This shows that tuberculosis was really present in these carcasses, but in an incipient form, the lesions being too slight for detection by ordinary post-mortem examination. It therefore seems that the percentnge of accuracy of the tuberculin test is even higher than is indicated by the figures above given. (Chief Bureau of Animal Industry.) I agree with resolution No. 2 of International Commission of American Veterinary Medical Association that " tuberculin properly used is an accurate and reliable diagnostic agent for the detection of active tuberculosis in cattle. (Surgeon General U. S. Army.) In 97 per cent of those giving a positive reaction tuberculosis has been found to be present. ( Surgeon General U. S. Navy. ) The tuberculin test is a very reliable means of determining active tubercu- losis in cows tested. (Surgeon General Public Health and Marine-Hospital Service. ) Very reliable when test temperatures taken for 18 hours after injections, and all cattle showing either doubtful or typical reactions are removed. Even slight rises of temperatures which rise and fall gradually are very suspicious, e. g., 101.6, 101.9, 102.2, 102.3, 101.8, 101.7, 101.4. (Dr. William H. Park, New York, N. Y.) If the source of the cattle is known and recent tuberculinization has not been made, the tuberculin test is almost infallible in the hands of an expert inspector. (Dr. Henry L. Colt, Newark, N. J.) A positive result is of great value. A negative result of less value. (Dr. R. G. Freeman, New York, N. Y.) Within 3 per cent. Long series carefully done show better than this. (Dr. M. P. Ravenel, Madison, Wis.) Under the following conditions I consider the tuberculin test practically infallible : Use United States Department of Agriculture tuberculin. The animal must show a normal range of temperatvire preceding the injection of tuberculin and must be kept in a normal, quiet condition during the entire test. It is very important that the animal to be tested has not been tampered with before or during the application of the test, as many unscrupulous owners prepare their animals by the different methods that do defeat the object of the test. A great deal of criticism heard as to the unreliability and absence of uniform results of the tuberculin tests can be attributed to the fact that the animal to be tested has been tampered with prior to the application of the test. The veterinarian applying the test should have had a large experience in animal temperatures. He should have had experience with temperatures and physical symptoms presented by animals that have been tampered with, or in other words, doped. He should be familiar with the high temperature that occasionally appears from causes other than the reaction due to the presence of the tuberculin, which appears at a time he expects a typical tuberculous reaction. This of times causes confusion to the veterinarian of little experience. (Dr. T. A. Geddes, Kensington, Md.) Practically always. (Health officer Ann Arbor, Mich.) I do not know. (Health officer Baltimore, Md. ) In our application of the test all reacting animals showed tubercular lesions on post-mortem. Statistics compiled by investigators give 98 to 99 per cent positive when tests are applied by competent men. (Health officer Birmingham, Ala.) Nearly all infected animals react, especially those with active disease. (Health officer Bismarck, N. Dak.) Infallible if properly applied with reliable tuberculin. (Health officer Cleve- land, Ohio.) Successful and dependable in 97 per cent of cases in experienced hands. (Health officer Columbus, Ohio.) Negative except in tubercular cases. (Health officer Detroit, Mich.) Yes. (State board of health, Florida.) I have not had enough experience with it to say. (Health officer Jackson- ville, Fla.) 152 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. To about 95 per cent. (Health officer Kansas City, Mo.) In the tests in Lynchburg it has been found reliable in every instance. (Health officer Lynchburg, Va.) Entirely so in the hands of a skilled veterinarian. Of course cases that can be detected by physical examination should not be tested. (Health officer Montclair, N. J.) Tw^o c. c. per cow unless private tests have been made, and then 3 c. c. Out of 8,000 tests not one mistake has been made, 1. e., each covp killed showed tubercular lesions. (Health officer Portland, Oreg.) Most reliable test we have. Ninety-seven per cent of cases can be detected. (Health officer Providence, R. I.) Almost absolutely so. (Health officer Richmond, Va.) Ninety-seven per cent. (Health officer Rochester, N. Y.) Ninety-eight per cent. (Health officer Seattle, Wash.) Only by competent men, backed by State authority. (Health officer Syracuse, N. Y.) Practically absolute when tests are studied with good judgment as to other associated conditions of the animal. (Health officer Topeka, Kans.) According to scientists, about 98 per cent of condemned cattle are infected. (Straus Laboratory, Washington, D. C.) Not sufficiently perfected to be infallible. (John Thomas, Ednor, Md., presi- dent. Milk Producers Association.) Uncertain. Best authorities agree that the tuberculin test is not a reliable diagnostic for tuberculosis. (Sharon Dairy, Washington, D. C.) We believe it has been shown that the tuberculin test is reliable to show that the cows either have or have had tuberculosis in over 90 per cent of the cases. In order to be able to rely upon the tuberculin test we believe that all the fol- lowing conditions must be strictly complied with : (1) The owner of the cow must be absolutely honest toward the veterinarian. (2) The test must extend over a period of several months, so that the possi-' bility of previous dosing of the cow can be eliminated. (3) The state of health of the cow and the conditions surrounding it must be known to the veterinarian by personal examination. (4) The veterinarian must be skilled in administering tuberculin. (Note. — We believe that only a very few veterinarians and mostly those who have had great experience are competent to administer the dose and get accurate results.) (5) The tuberculin must have been prepared with the greatest care, and the veterinarians must know what the strength of the tuberculin is. (Note. — Com- mercial tuberculin is of varying strength and sometimes impure.) (6) The dose of tuberculin must be of the right amount and strength. If there is an overdose of tuberculin the cows, although healthy, would react. (Note. — The tuberculin test is so delicate and so liable to err that it should be used to corroborate the clinical evidence of disease and not as a sole test of the presence of the disease in apparently healthy cows.) (7) Animals suffering from diseases other than tuberculosis will react upon the injection of tuberculin. We believe the following are the inaccuracies of the tuberculin test : (1) A cow which may have had at some time during her life a slight infec- tion of tuberculosis and had entirely recovered, and the lesion calcified and healed, will still react to the tuberculin test, although she is perfectly healthy at the time of the test. (2) A diseased cow which has been injected with tuberculin within a period of three months previous to the test will not react. (3) A diseased cow, which is fed with febrifuge (antiperitic), just before the dose, will not react. (4) Healthy cows, if excited at the time of the test, will react. (5) If the test is administered in hot weather, and the cows are driven from the fields into the stable during the time of the test, healthy cows may react. (6) In advanced cases of tuberculosis no reaction is obtained upon the injec- tion of tuberculin. (7) A cow may not react if infected during the period of incubation, which ranges from 8 to 50 days. (8) It may be that timothy bacilli will cause reaction, and those bacilli, so far as we know, are harmless. It is believed by many authorities that the injection of tuberculin is dan- gerous to healthy cows, in that it may cause latent tuberculosis to develop into THE MILK SITUAl:iO]Sr IN THE DISTRICT OF COLITMBIA. 153 acti^^e tuberculosis, or so weaken its resistive power that it becomes more liable to take the infection. We consider, however, that the greatest objection to the reliability of the tuberculin test to show that the cow is diseased with active tuberculosis is the fact that cows which have practically recovered from the infection, where the lesions are encysted and calcified, react as typically as cows that are actively diseased. We have the results of a tuberculin test and a post-mortem examination of reacting animals of two herds, made ofiicially under the New York State De- partment of Agriculture, which may be stated generally as follows : In one herd 44 cows were tested and 24 reacted. None of them had any lesions of the udder. Of these 24, 4 carcasses were condemned as having generalized tuberculosis and were tanked; the remaining 20 carcasses were passed as fit for food ; in all but one there was not more than one or two glands affected, and all of these glands calcified. In one (which was par- ticularly picked out for special demonstration and slaughter at the Tompkins County Fair at Ithaca), when it came to be slaughtered no lesions were found whatever, so that the net result of the condeming of 24 cows of that herd was that 4 of them were badly affected. Two of these cows had been condemned on physical examination before the examination of the tuberculin test, so that had they been taken out of the herd the tuberculin test would have condemned 50 per cent of that herd, and of that 50 per cent only 1 per cent were badly affected. In the second herd there were 56 cows and 10 calves tested. Eleven cows and four calves passed the tuberculin test. Eight animals were selected by physical examination as being infected before testing by tuberculin. Fifty-one were slaughtered. In 4 of them no lesions could be found, and 39 carcasses were passed for food, and 6 were condemned as having generalized tuber- culosis, and the carcasses were tanked. In 28 all the lesions were found to be calcified ; the cows were fine, big cows and good milkers. These two^ herds were not selected, but were herds which were tested and condemned under the New York State department of agriculture. We had nothing to do with it, but we were allowed to attend and to take note of the results. It is only fair to say that the United States Government experts claim that no one can tell when cows that contain calcified lesions may not develop active tuberculosis again under unfavorable conditions or sickness, such as pneumonia, and that therefore they are dangerous and should be removed from the herds. We hold, however, that in view of the fact that so many human beings have, at some time or other, been actively affected by tuberculosis, and have re- covered and lived long and useful lives and died of other diseases, we think it is but fair to give any cow whose vitality was sufficient to calcify the lesions the benefit of the conclusion that probably, if she had not been killed, she would have remained a valuable producer of milk for a number of years unless, of course, taken sick. In that case she would not be fit to be a milk producer, but such sickness would be evident to the dairyman. Therefore we believe, after a very careful study of the whole situation, that the reaction following the tuberculin test is not a reliable means of de- termining whether the cow is then suffering from active tuberculosis. (Borden's Condensed Milk Co., New York, N. Y.) In 3,000 tests less than one-half to 1 per cent of the temperature readings have been doubtful. All reactions confirmed by post-mortem, and have no reason to suppose that in more than three cases have infected animals passed as sound. (Walker-Gordon Laboratory, Washington, D. C.) Almost absolute. (Dr. V. O. Vaughan, Ann Arbor, Mich.) "Very reliable when carried out with intelligence and care. (Dr. S. C. Pres- cott, Boston, Mass.) Reliable in over 97 per cent of the cases when tested by competent men. (Health officer Los Angeles, Cal.) Very great extent. (J. M. Houston, White Cross Milk Co., Washington, D. C.) If carefully done, almost infallible. According to Bang, error is only 3.3 per cent. (Health officer San Francisco, Cal.) The reliability depends upon the skill and honesty of the person making the test. (Health officer St. Joseph, Mo.) About 96 per cent. (Health officer Wheeling, W. Va.) 154 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. To a fraction of 1 per cent, if pro])erly applied. (Dr. O. J. Marshall, Uni- versity of Pennsylvania, Philadelphia, Pa.) To show presence of first infection. (Health officer Scranton, Pa.) Question 3. — What effect in your judgment would its enforcement have on the price of cattle? ANSWERS. The prices of cows, as well as prices of other things, have increased all over the country within recent years, regardless of whether or not the tuberculin test has been applied. The statistics of the Department of Agriculture show that the average value of milch cows on January 1, 190S, was $30.67 per head, while the average value on January 1, 1910, was $35.79 per head, an increase of 16.7 per cent in two years. While it is possible that the price of cows might be affected if the tuberculin test were applied simultaneously over a large part of the country and all reacting animals slaughtered, it is believed that the gradual application of the test, followed by slaughter, carried ont in a small area, would have no perceptible effect upon prices. As the milk of tuberculous cows is unquestionably dangerous to human health and life, a slight increase in the price of cows and in the cost of milli should certainly not be considered as an adequate reason for refusing to take steps to remove this danger. Cows affected with tuberculosis are usually not as productive as healthy cows, and their value as milk producers would probably steadily decrease, hence the removal of cows of this class would not be as great a loss as might appear at first. (Chief Bureau of Animal Industry.) Ultimately little or none. (Surgeon General U. S. Army.) It would undoubtedly raise it. (Surgeon General U. S. Navy.) Enforcement of the tuberculin test would probably increase temporarily the price of healthy dairy cows. ( Surgeon General Public Health and Marine- Hospital Service.) I would at first separate the reacting cattle when in sufiicient numbers to be practicable, and use their milk pasteurized. This would lessen effect on price. (Dr. William H. Park, New York, N. Y.) Its enforcement would increase the price of cattle from 25 to 50 per cent. (Dr. Henry L. Coit, Newark, N. J.) Little or none. (Dr. R. G. Freeman, New York, N. Y.) Not able to answer. A healthy cow is worth more than a sick one. Event- ually no effect should be produced. (Dr. M. P. Ravenel, Madison, Wis.) Have not statistics. (Dr. T. A. Geddes, Kensington, Md.) Slight increase. (Health officer Ann Arbor, Mich.) I do not know. (Health officer Baltimore, Md.) Locally tuberculous-free cows are estimated to be worth from $2 to $5 more than cows that have not successfully passed the test. (Health officer Birming- ham, Ala.) No appreciable effect. (Health officer Bismarck, N. Dak.) Would depend upon degree and rapidity of enforcement ; probably raise the price of tuberculin-tested cattle materially. (Health officer Cleveland, Ohio.) Increased valuation. (Health officer Columbus, Ohio.) Temporary rise. (Health officer Detroit, Mich.) The Immediate effect would be to raise the price, but the remote effect would be to conserve the health and vitality of the cattle and consequently reduce the price. (State board of health Florida.) None at all here, as it is done without cost to the dairyman, and few diseased cows are found in this locality. (Health officer Jacksonville, Fla.) This question is not specific. Do you mean milk cows; if so, yes. (Health officer Kansas City, Mo.) A^'ery little. (Health officer Lynchburg, Va. ) Have no experience, but would judge that price of known sound cattle would be higher than of possibly diseased cattle. Ultimate price in a few j^ears ought to be as low as at present if tuberculosis is eradicated. (Health officer Mont- clair, N. J.) Temporary increase, but later will not affect except that the buyer of milk cows would feel safe in his investment. (Health officer Portland, Oreg.) At first mighl! increase price. (Health officer Providence, R. I.) THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 155 Depends upon circumstances. If a few cities insist on test, the price of tuber- culin-tested cows (which alone we would have to consider) would be the same as for tuberculin-tested cows everywhere else. (Health officer Richmond, Va.) I do not know. It has had no effect as yet. (Health officer Rochester, N. Y. Probably somewhat — not very great — because the life of cows as a whole would be lengthened; therefore progeny would be entailed. (Health officer Seattle, Wash.) It would increase the price. (Health officer Syracuse, N. Y.) Little, if any. (Health officer Topeka, Kans.) Owing to the prevalence of tuberculosis among cattle, the enforcement of the tuberculin test would undoubtedly raise the price of healthy cows. (Straus Laboratory, Washington, D. C.) It would increase the price 20 to 30 per cent. (Sharon Dairy, District of Columbia.) Raise the price 25 per cent. (John Thomas, Ednor, Md., president Milk Producers' Association. We believe that it would very greatly increase the price of cattle, and our judgment is based upon our investigations of what has taken place in Massa- chusetts and other States where they have attempted to enforce the test. (Bor- den's Condensed Milk Co., New York, N. Y.) In my judgment the enforcement of the tuberculin test would very materially increase the price of dairy cattle. (Walker-Gordon Laboratory, Washington, D.C.) Increase. (Dr. V. C. Vaughan, Ann Arbor, Mich.) It would increase the price of milch cows and probably of other cattle as well. (Dr. S. C. Prescott, Boston, Mass.) Depends on how reactors are handled. (Health officer Los Angeles, Cal.) Twenty-five to 50 per cent. (J. M. Houston, White Cross Milk Co., Wash- ington, D. C.) Increase. (Health officer San Francisco, Cal.) It might cause a temporary rise in price of tested cows and might, if exten- sively .enforced, affect the general price of cattle. (Health officer St. Joseph, Mo.) Price would advance for the time being. (Health officer, Wheeling, W. Va.) It would undoubtedly increase the price of cattle for a few years. (Dr. C. J. Marshall, University of Pennsylvania, Philadelphia, Pa.) Create higher prices. (Health officer Scranton, Pa.) Question 4. — In your judgment, should the expense of the test he defrayed by the Government or the owner? The Government or the State should bear the expense of making the tuber- culin test when this is officially required in the interest of the public health. The Department of Agriculture is willing to test without charge herds supply- ing milk to the District of Columbia, and will extend similar cooperation to State and city authorities elsewhere so far as possible. (Chief Bureau of Animal Industry.) It would be desirable in the interest of public health for the State govern- ments to assume the expense. (Surgeon General U. S. Army.) By the Government. (Surgeon General U. S. Navy.) The question as to whether the Government should bear the expense of apply- ing the tuberculin test is one of policy, regarding which I am not in a position to give an opinion at 'the present time. (Surgeon General Public Health and Marine-Hospital Service. ) At first by State, then later by farmers. (Dr. William H. Park, New York, N. Y.) The expense should be defrayed by the Government through its own inspect- ors, although owners are learning that it is a pecuniary advantage to have clean cattle. (Dr. Henry L. Coit, Newark, N. J.) Owner. (Dr. R. G. Freeman, New York, N. Y.) Owner. It is easier to introduce it by free tests, or at least a sharing of the expense, but this should be temporary. (Dr. M. P. Ravenel, Madison, Wis.) There is hot the slightest doubt in my mind that an attempt to eradicate tuberculosis in our herds will come. I favor the method that will bring such an attempt the quickest, whether it be the Government, State, or county 156 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. authorities. I feel sure that if the campaign of education be inaugurated bo that the farmer could be educated and shown where he could benefit, he would willingly assume his share of cost. As for the Government to undertake the eradication of tuberculosis without some local help, it would be an enormous task. (Dr. T. A. Geddes, Kensington, Md.) Government. (Health officer Ann Arbor, Mich.) By the Government. (Health officer Baltimore, Md.) Either by National, State, or municipal Government. (Health officer Bir- mingham, Ala.) Owner. (Health officer Bismarck, N. Dak.) Should be divided between owner and State government. (Health officer Cleveland, Ohio. ) Both. (Health officer Columbus, Ohio.) Government. (Health officer Detroit, Mich.) By the Government. (Health officer Jacksonville, Fla.) Government or State, by competent officers. (Health officer Kansas City, Mo.) Would be cheaper for the Government and probably better. (Health officer Lynchburg, Va. ) Test by Government or city. Loss of cattle to be met by owner, the same as the loss of any other diseased animal. (Health officer Montclair, N. J.) By the Government, either municipal. State, or United States, preferably State, with partial remuneration for condemned cows. (Health officer Port- land, Oreg. ) If people want clean milk, should pay for it. The expense of test should be borne by Government. (Health officer Providence, R. I.) In a general way by Government, but imposition would then have to be carefully guarded against. (Health officer Richmond, Va.) The owner and Government should share the expense. (Health officer Roch- ester, N. Y. ) I believe the period should be fixed within which all cattle destroyed should be in some manner paid for by the State. After such period all diseased stock should fall as a loss against the owner. (Health officer Seattle, Wash.) ^ By the State. (Health officer Syracuse, N. Y.) A part by each. (Health officer Topeka, Kans.) It is a movement for the protection of the public health, therefore the ex- pense should be borne by the public, i. e., the Government. ( Straus Laboratory, Washington, D. C.) Two-thirds by the Government; one-third by the owner. (John Thomas Ednor, Md., president Milk Producers' Association.) If compulsory, by the Government; if voluntary, by the owner. (Sharon Dairy, Washington, D. C.) We have been advised of so many instances of fraudulent tests and fraudu- lent records that we are of the opinion that the tuberculin test, if required, should be applied by the Government, and its expense defrayed by the Govern- ment; and that it should be applied only by veterinarians who have had large experience, and are of high standing and entirely beyond reproach with regard to honesty. In addition, the enforcement of the test is for the public good or necessity, and the expense should therefore be borne by the Government. (Borden's Condensed Milk Co., New York, N. Y.) The method now followed by the State of Pennsylvania seems quite practical. Under it the test is optional with the owner, and is made at expense of State. The owner receives two-thirds of appraised value of cattle condemned, but not in excess of $75 per head. (Walker-Gordon Laboratory, ^Vashington, D. C.) Divided. (Dr. V. C. Vaughan, Ann Arbor, Mich.) I think the cattle owner should be sufficiently interested in protection of his herd to pay actual cost of test. I admit that many are not. (Dr. S. C. Pres- cott, Boston, Mass.) By the Government. (Health officer Los Angeles, Cal.) The Government at this time and for some years in part to come, unless the owner got more money for his product, which would mean higher price to the consumer. (J. M. Houston, White Cross Milk Co., Washington, D. C.) Both, if possible. (Health officer San Francisco, Cal.) An average allowance should be made for each cow tested for a certain period after the law becomes effective, and thereafter the loss by condemnation should be borne by the owner. (Health officer St. Joseph, Mo.) By the Government. (Health officer Wheeling, W. Va.) THE MILK SITUATION IIST THE DISTRICT OF COLUMBIA. . 157 In most cases by the Government. Owners should be allowed to pay for the test, if they will have it applied by competent persons. (Dr. C. J. Marshall, University of Pennsylvania, Philadelphia, Pa.) Government. (Health officer Scranton, Pa.) Question 5. — What is the approximate expense of applying the tuberculin test? ANSWEES. The expense of applying the tuberculin test would vary considerably with the number of cows in each herd, the distances separating herds, etc. In case the testing is not done by the Government without charge, as above suggested, it could probably be done at an average cost of about $1 per cow. (Chief Bureau of Animal Industry.) I have no exact information on this subject, but the process is a simple one and should be inexpensive. ( Surgeon General U. S. Army. ) Must vary under a variety of conditions. (Surgeon General U. S. Navy.) Slight, if done in large numbers and by suitable persons. (Dr. S. C. Pres- cott, Boston, Mass.) At private tests, when in numbers, about $1 per head. (Dr. William H. Park, New York, N. Y.) The expense depends upon the size of the herd; it costs as much to test two cows as a dozen. The expense is chiefly in the time of the veterinarians. (Dr. Henry L. Coit, Newark, N. J.) Varies with size of herd. (Dr. R. G. Freeman, New York, N. Y.) Depends on size of herd and thickness of population. Should not exceed 50 cents per head ordinarily. On our results of herds of about 50 cows the expense of the test would cost approximately 44 cents per animal. Larger herds the expense would be largely reduced, while there would be an increase on smaller herds. (Health officer Birmingham, Ala.) Two dollars. (Health officer Bismarck, N. Dak.) Depends on local conditions and customs. (Health officer Cleveland, Ohio.) About $1 per capita. (Health officer Columbus, Ohio.) Depends on herd, location, etc. (Health officer Detroit, Mich.) Depends upon size of herd. Average herd of 30 cows, from 50 cents to $1. (Health officer Kansas City, Mo.) When the herd reaches 30 or more the actual expense per cow is little. One herd of 150 cows in Lynchburg had only one reaction, a fine Jersey. On kill- ing, one lung was sadly affected. (Health officer Lynchburg, Va.) Depends on the size of the herd. It will take a veterinarian the best part of a day to test a herd, whether of 10 or 50 cows. (Health officer Mont- clair, N. J.) Governed by conditions; large herds can be tested at relatively less expense than small ones; that is, it takes as much time to test 20 cows as it does 50. (Health officer Portland, Oreg.) Depends upon the number of cows in herd and distance farms are apart. (Health officer Providence, R. I.) Depends on what is meant by this question. If mere cost of injection and passing or reaction, cost for large herds should be light per cow. If " apply- ing test " includes doing away with reacting animals, cost is very great, and for all cows supplying a city the cost is enormous to somebody. (Health officer Richmond, Va.) Very small, depending on size of herds. (Health officer Rochester, N. Y.) It costs the department $5 per day for our veterinarian, $3 for a helper, and 9 cents a dose for tuberculin. If one cow only was tested, you could cut out, of course, the helper. The cost for testing a herd would be nothing like this. (Health officer Seattle, Wash.) Depending on size of herds. A large herd can be tested as easily as a small one, and if the work be systematized one herd a day could be tested at expense of, say, $5. (Health officer Topeka, Kans.) It depends much upon the size of the herd. A herd of 50 cows can be tuber- culin tested as cheap as 1 cow. The only additional expense, the amount of tuberculin used. (Sharon Dairy, District of Columbia.) It is practically impossible to make any suggestion as to the approximate expense, unless the conditions under which it is to be applied are given. In general, however, if the work is done by a veterinary practitioner and the herd 158 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. is not over 3 miles distant from his office, it can be done for $15 on the basis of 25 cows in the herd, and for $20 for 50 to 75 cows in a herd, and for $25 for 100 cows in a herd, including the cost of tuberculin, which is about 5 cents per dose. If the work was done by a State veterinarian it would then cost whatever his salary per diem was, including what the necessary traveling and hotel expense would amount to. (Borden's Condensed Milk Co., New York, N. Y.) As one competent man is required to test a single cow, but can in the same time test 100 cows, it is quite impossible to fix an approximate figure for the expense. (Walker-Gordon Laboratory, Washington, D. C.) It depends on number of cattle to be tested and whether test is made by practicing veterinarian or by Government or State officer (25 cents to $5 a head). (Health officer Los Angeles, Cal.) The cost of testing is slight; the loss of cattle to the owner may be heavy. (J. M. Houston, White Cross Milk Co., Washington, D. C.) Very little (about 50 cents), but besides two days' labor, (Health officer San Francisco, Cal.) I do not know. (Health officer Wheeling, W. Va.) An experienced man can test as many as 100 head in one night. He should receive approximately $40 for such a night's work. A few animals may be tested for less money, but probably not less than $15 for one animal. The Pennsylvania Live Stock Sanitary Board allows $5 per day and expenses. (Dr. C. J. Marshall, University of Pennsylvania, Philadelphia, Pa.) Depends upon conditions — whether single animal or herd. (Health officer Scranton, Pa.) Question 6. — What length of time is required in applying the test? ANSWEBS. The time required for making the tuberculin test is on the average about 24 hours, covering parts of two days. (Chief Bureau of Animal Industry.) I believe it requires two or three ds^ys to test a herd. ( Surgeon General U. S. Army. ) Between two and three days. ( Surgeon General U. S. Navy. ) Forty-eight hours. (Dr. V. C. Vaughan, Ann Arbor, Mich.) Two days for a herd of moderate size (50 to 100). (Dr. William H. Park, New York, N. Y.) Twenty -two hours. (Dr. Henry L. Coit, Newark, N. J.) Twenty-four hours. Nonreacting animals do not require quite so long. (Dr. M. P. Ravenel, Madison, Wis.) Thirty hours. (Dr. T. A. Geddes, Kensington, Md.) Test can be completed within 32 hours after the commencement of the work. The temperatures should be taken until at least 20 hours after the injection of the tuberculin. (Health officer, Birmingham, Ala.) Two days. (Health officer Bismarck, N. Dak.) Two days to each herd. (Health officer Cleveland, Ohio.) At least 27 hours. (Health officer Cleveland, Ohio.) Twenty-four to 36 hours. (Health officer Detroit, Mich.) Twenty-four to 48 hours. (State Board of Health, Florida.) About 48 hours. (Health officer Jacksonville, Fla.) Forty-eight hours. (Health officer Kansas City, Mo.) See any authority on the subject. Inject at 6 to 8 p. m., and take tempera- tures until about 2 p. m. on following day. (Health officer Montclair, N. J.) Not less than 36 hours. (Health officer Portland, Oreg.) Inject tuberculin in evening, and about daylight next day take tempera- tures every 2 hours for 12 to 15 hours. (Health officer Providence, R. I.) One to two days. (Health officer Rochester, N. Y.) Twenty-four hours. (Sharon Dairy, District of Columbia.) One half of each of two days. (Health officer Topeka, Kans.) Twenty-four hours. (Sharon Dairy, D. C. ) Ordinarily the tuberculin test requires about 44 hours after the veterinary has arrived at the farm, but, as above stated, must be repeated after an interval of six months to be complete. (Borden's Condensed Milk Co., New York, N. Y.) THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 159 The tester should give two full days' time, but temperature measurements should be taken for two days prior to this to prevent testing an animal whose temperatures are showing marked variation. (Walker-Gordon Laboratory, "Washington, D. C.) One or two days. Should be repeated after three or six months. (Dr. S. C. Prescott, Boston, Mass.) From 18 to 24 hours. (Health officer Los Angeles, Cal.) Two days. One day previous in taking temperatures before injection, and one day noting results. (Health officer San Francisco, Cal.) Approximately two days. (Health officer, Wheeling, W. Va.) Twenty-four hours. (Dr. C. J. Marshall, University of Pennsylvania, Phila- delphia, Pa.) About 24 hours. (Health officer Scranton, Pa.) Question 7. — Granting that the test should be applied only l)y governmental authorities or qualified agents duly authorized thereby, would it he practicable and advisable to restrict the use of tuberculin and its application to such authorised officials or agents? Yes. (Chief Bureau of Animal Industry.) Restriction is not necessary, but only the certificate of authorized officials or agents should be recognized. (Surgeon General U. S. Army.) Yes, (Surgeon General U. S. Navy.) The tuberculin test should be administered by governmental authorities, or certainly under their supervision. ( Surgeon General Public Health and Marine- Hospital Service.) I believe not, because of the difficulty and expense when in out-of-the-way places. I believe reacting cattle should be reported in confidential way to au- thorities. (Dr. William H. Park, New York, N. Y.) Yes; if the work was done in conjunction with the State authorities. (Dr. Henry L. Coit, Newark, N. J.) Yes. (Dr. R. G. Freeman, New York, N. Y.) Yes. (Dr. M, P. Ravenel, Madison, Wis.) Animals often show irregular temperatures during test that have been filled up with tuberculin previous to such testing. Repeatedly injecting tuberculin in animals to be presented for an authentic test is one of the many methods that is used to defeat the object of the test. I would certainly restrict the use of tuberculin. (Dr. T. A. Geddes, Kensington, Md.) No. (Health officer Ann Arbor, Mich.) Yes. (Health officer Baltimore, Md. ) I think not. (Health officer Birmingham, Ala.) Yes. (Health officer Bismarck, N. Dak.) Very desirable, but not practical in some States owing to their laws. (Health officer Cleveland, Ohio.) Yes. (Health officer Columbus, Ohio.) No. Health officer Detroit, Mich.) Not necessary, I think. (Health officer Jacksonville, Fla.) Yes. (Health officer Kansas City, Mo.) Yes. (Health officer Lynchburg, Va.) It would be most advisable if this could be done, as it would stop a lot of crooked work. (Health officer, Montclair, N. J.) No. The test being very simple, owners often test their cows for their own individual protection. (Health officer Portland, Oreg.) The test should be applied by Government agents or licensed veterinarians. (Health officer Providence, R. I.) This would have to be done. (Health officer Richmond, Va.) Yes. (Health officer Rochester, N. Y.) Decidedly and most emphaticallly yes. A tuberculin test is valueless, in my judgment, unless you know that the stock has never been tested; and in any event know exactly what occurred. (Health officer Seattle, Wash.) Yes. (Health officer Syracuse, N. Y.) Yes. (Health officer Topeka. Kans.) Yes. (Straus Laboratory, Washington, D. C.) 160 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. If the test must be made, it should be applied by competent men. (John Thomas, Ednor, Md., president Milk Producers' Association.) Yes, the Government should control the tuberculin, and only qualified veter- inarians should be allowed to use it, and they should be required to report to the Government how it was used. (Sharon Dairy, District of Columbia.) No, by no means. To take tuberculin away from the profession, assuming that such a thing could be done, and restrict its use entirely to Government agents would be an unfair discrimination against the needs and rights of the individual cattle owners and an unjust restriction on the scope and rights of the veterinary profession. (Borden's Condensed Milk Co., New York, N. Y.) It should be practical, and it would unquestionably be advisable, to restrict application of this test to qualified and trustworthy persons, as it is a well- known fact that after one injection an animal may not again react to a similar injection, even six months later. (Walker-Gordon Laboratory, Washington, D. C.) No. (Dr. V. C. Vaughan, Ann Arbor, Mich.) I see no reason why an owner of cattle should not make this test if he wishes and has the requisite knowledge. (Dr. S. C. Prescott, Boston, Mass.) Decidedly advisable. Doubt if it would be practical to exclude registered veterinarians from its use. (Health ofiicer Los Angeles, Cal.) Yes. (J. M. Houston, White Cross Milk Co., Washington, D. C.) No. (Health officer San Francisco, Cal.) Yes. (Health officer St. Joseph, Mo.) Yes. (Health officer Wheeling, W. Va.) Yes. (Dr. C. J. Marshall, University of Pennsylvania, Philadelphia, Pa.) Question 8. — Should the otoner he compensated for cattle condemned, and on what hasis of payment? Owners should be compensated at least in part for cattle condemned. The basis of condemnation in the recent work in the the District of Columbia is shown by the accompanying copy of the order of the commissioners. In brief, cattle were appraised before slaughter, the appraisal not to exceed $75 for a pure-bred or registered animal, or $50 for a grade or unregistered animal. Eighty per cent of the appraised value, less the amount realized as salvage, was paid on cattle whose carcasses were passed for food on post-mortem inspec- tion, and 40 per cent less salvage in the case of cattle condemned for offal. If a reacting animal showed no lesions of tuberculosis on post-mortem examina- tion, the full appraised value less salvage was paid. It is believed that the respective States, where cattle are owned, should make provision for compensa- tion for cattle slaughtered as a result of the tuberculin test in those States. Several Sates have laws providing for such compensation. (Chief Bureau of Animal Industry.) Compensation is desirable ; certainly in the beginning. One-half the value of the animal would be a fair basis. Surgon General U. S. Army. ) The fullest compensation should be allowed for cattle wholly condemned. (Surgeon General U. S. Navy.) Compensation, or part compensation, for cattle destroyed on account of tuber- culosis is provided for in certain States, some of them being New York, Kansas, Connecticut, Missouri, Vermont, and the District of Columbia. Such compensa- tion appears to be just, but it follows that owners of cattle should be required to observe those sanitary measures necessary to protect their herds from tuber- culosis. (Surgeon General Public Health and Marine-Hospital Service.) Yes; for those in good condition; not for others. (Dr. William H. Park, New York, N. Y. Yes; on the basis of two-thirds their value. (Dr. Henry L. Coit, Newark, N. J.) Yes; part value. (Dr. R. G. Freeman, New York, N. Y.) Yes; as a temporary measure. Two-thirds value, with fixed maximum, is fair basis. (Dr. M. P. Ravenel, Madison, Wis.) I hardly feel able to give an opinion of any value to so weighty a question. The facts that are not to be disputed are that tuberculosis is present in our herds of cattle and swine. Twenty years ago the percentage was much less than it is to-day, the increase, especially among hogs, being generally alarm- ing. Hogs are generally infected through cattle. The facts are before us THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 161 that the longer we delay the more tuberculous animals we will have to deal with ; also the greater number of animals to be compensated for should State or Nation compensate. Heavier would fall the blow on the farmer or owner of diseased cattle would he have to stand the loss. In England cattle found tuberculous on post-mortem by meat inspectors and condemned, are compensated for by a form of insurance arranged among the farmers and the butchers. I be- lieve in compensation by State or Nation, as this would do away with a great deal of crookedness, it would tend to obtain cooperation of the parties inter- ested, and aid most emphatically in the ultimate elimination of tuberculosis from our dairy herds. It has been my experience in England that men with tuberculous cattle will never welcome the tuberculin test until it pays them to do so. (Dr. T. A. Geddes, Kensington, Md.) Theoretically, no; possibly yes, at first. (Health officer Ann Arbor, Mich.) If the owner has provided the best sanitary condition for his cattle the ex- pense should be borne by the Government. If he has not provided such condi- tions, then by the owner. (Health officer Baltimore, Md.) I think the owner should be reimbursed on a basis of about two-thirds ap- paised value of animals condemned. (Health officer Birmingham, Ala.) Yes; one-half. (Health officer Bismarck, N. Dak.) Fifty per cent of appraised value, together with privilege of selling for im- mediate slaughter under proper inspection, should be given. (Health officer Cleveland, Ohio.) Yes; in Ohio the State pays one-half the appraised value. (Health officer Columbus, Ohio. Percentage. (Health officer Detroit, Mich.) No. (State board of health, Florida.) Yes; at as nearly the market price as possible, (Health officer Jackson- ville, Fla.) Upon the basis for which- they are assessed; two-thirds valuation. (Health officer Kansas City, Mo.) Should be compensated to about 50 per cent of a price previously agreed on. Owner gets his price for selling a good milk, and he should stand his loss the same as he would if potatoes or any other crop went bad. He would not ask Government to pay for diseased chickens that he could not market. (Health officer Montclair, N. J.) Yes. I think for this purpose a stated valuation should be placed on the cow, and 60 per cent of said valuation be paid by State. (Health officer Port- land, Oreg.) Full value. (Health officer Providence, R. I.) Yes. In whole or in part, but every safeguard would be necessary. (Health officer Richmond, Va.) No; but New York State pays 80 per cent for cattle with localized lesions, 50 per cent for general lesions. (Health officer Rochester, N. Y.) Yes. Because under our laws a clean herd may be contaminated from out- side sources. I can not answer intelligently this question in the space allotted. (Health officer Seattle, Wash.) Yes; by appraisement. (Health officer Syracuse, N. Y.) Such compensation makes a better feeling of owner toward Government, and as the work is for the benefit of the whole people the latter, represented by the Government, should bear at least part of the expense, say one-half fair valuation each in case of apparently good cows, less share by Government in case of very poor. (Health officer Topeka, Kans.) Yes. Do not know. (Straus Laboratory, Washington, D. C.) Yes. On a basis fixed by disinterested appraisers. (John Thomas, Ednor, Md., president Milk Producers' Association.) If compulsory the Government should pay. If voluntary the owner should pay. (Sharon Dairy, District of Columbia.) If the tuberculin test is to be enforced at once and in a drastic way without first giving the dairymen a year or more notice of its enforcement, with the privilege of cleaning up their herds as best they can before its application, we think that the owner should be compensated for all cattle condemned, and that the basis of payment should be regulated to a certain extent by the condition of the animal when slaughtered. For instance, if a cow is found to have been only recently infected, or that the lesions are all encysted and calcified, the owner should receive full value for such cow. If, however, the cow is in bad 82444°— S. Doc. 863, 6X-3 ^11 162 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. shape, and there are many tuberculous lesions, and the owner might have elimi- nated that cow by physical inspection, we think that then the amount to be paid should be on a rapidly descending scale. The method now followed by the State of Pennsylvania seems quite practical. Under it the test is optional with the owner and is made at expense of State. The owner receives two-thirds of appraised value of cattle condemned, but not in excess of $75 per head. (Walker-Gordon Laboratory, Washington, D. C.) In part, but I can not say how much. (Dr. V. C. Vaughan, Ann Arbor, Mich. ) A broad question. I think the Bang system should be introduced so that mildly infected cattle might be isolated and used for breeding (once). Badly infected cows should be killed at once and a fair value (beef value?) paid. (Dr. S. C. Prescott, Boston, Mass.) Yes, at least for the first two or three tests. Seventy-five per cent of appraised valuation less returns from offal in condemned animals and from meat in passed animals. (Health officer Los Angeles, Cal.) He should be compensated in full now. Later, if he gets more for his milk, he should stand the expense. (J. M. Houston, White Cross Milk Co., Wash- ington, D. C.) An average allowance should be made for each cow tested for a certain period after the law becomes effective, an thereafter the loss by condemnation should be borne by the owner. (Health officer St. Joseph, Mo.) He should be compensated. Personally, I think he should receive about 75 per cent of the value. (Health officer Wheeling, W. Va.) The present Pennsylvania plan is quite satisfactory. The State to allow three-fourths of the appraised value of the animal. The animal to be killed under inspection. The meat sold, if passed by the inspector, the owner re- ceiving not more than 5 cents per pound, dressed weight, provided the amount received from the State and the butcher does not exceed 90 per cent of the appraised value of the animal. (Dr. C. J. Marshall, University of Pennsyl- vania, Philadelphia, Pa.) Yes. Ninety per cent of actual value. (Health officer Scranton, Pa.) Question 9. — In the absence of compulsory pasteurization, should tests other than the tuberculin test be required to safeguard against typhoid, diphtheria, dnd other deleterious germs? ANSWERS. The tuberculin test only guards milk against infection with cattle tuberculosis. It would still be necessary to take other precautions against the infection of typhoid fever, diphtheria, and other communicable diseases. Very few infectious diseases besides tuberculosis are communicable to people from cows. The danger of other diseases arises from contamination through the water supply or by persons handling the milk. There should be an occasional inspection of prem- ises, attendants, methods of handling milk, etc., and an examination of the water supply. The families of those handling the milk should also be sub- jected to examination to guard against the spread of contagious diseases, and there should also be a requirement of compulsory notification of the health officer on the appearance of any contagious disease among attendants or their families. The score-card system of dairy inspection should be used. (Chief Bureau of Animal Industry.) The sense of the question is not clear. Cows are not subject to typhoid fever and diphtheria. (Surgeon General U. S. Army.) It is not practicable to apply other tests effectively. (Surgeon General U. S. Navy.) In the absence of compulsory pasteurization, thorough inspection should be made, both of the dairy and those having to do with the handling of the milk, to prevent its contamination with the infection of typhoid fever, diphtheria, and scarlet fever. (Surgeon General Public Health and .Marine-Hospital Service. ) General hygienic rules; examination of feces before return of typhoid con- valescents ; inspection of wells ; and report of all suspected communcable dis- eases. (Dr. William H. Park, New York, N. Y.) The tuberculin test, without efficient pasteurization or other sanitary precau- tions, would not be a sufficient safeguard. (Dr. Henry L. Coit, Newark, N.J.) Yes ; low bacterial count and clean conditions at dairy and healthy employees. (Dr. R. G. Freeman, New York, N. Y.) THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 163 Yes. (Dr. M. P. Ravenel, Madison, Wis.) There are no practical tests. (Dr. O. E. A. Winslow, New York, N. Y.) Yes. (Health officer Ann Arbor, Mich.) Yes. (Health officer Baltimore, Md. ) No; there is no practical test of dairy cows for typhoid or diphtheria. (Health officer Birmingham, Ala.) No. (Health officer Bismarck, N. Dak.) None are practical under existing conditions. (Health officer Cleveland, Ohio.) Using the word " test " in the sense of activities, I should answer : Enforce- ment of dairy regulations reenforced by laboratory findings. (Health officer Columbus, Ohio. Rigid inspection. (Health officer Detroit, Mich.) Typhoid fever, diphtheria, scarlet fever are not safeguarded by any test applied to cattle, but the source of distribution is to be found- and guarded in personnel of those handling the milk. (State board of health, Florida.) No ; competent dairy inspection and a dairy register of infectious diseases. (Health officer Jacksonville, Fla.) Do not think so; latter produced by contact. (Health officer Kansas City, Mo.) Don't understand this question. How would you test? For instance, a cow does not have typhoid. (Health officer Lynchburg. Va.) I am not aware of any telsts that could be used in actual practice. (Health officer Montclair, N. J.) Tuberculin test indicateis tuberculosis ; does not affect typhoid, diphtheria, or scarlet fever. (Health officer Portland, Oreg.) See inclosures. [Appendix G.] (Health officer Providence, R. I.) No other tests possible that I know of. Competent inspection and insistence of rule [Appendix G] and immediate study of all reported cases of these dis- eases (with reference to milk included) accomplish a great deal. (Health officer Richmond, Va.) No ; the determination of outbreaks of milk-borne typhoid and diphtheria can be determined in other ways. (Health officer Rochester, N. Y.) No ; I think not. I believe inspection by our sanitary and medical department covers this feature fully, at least in this city. (Health officer Seattle, Wash.) Yes. (Health officer Syracuse, N. Y. ) Only such tests as carefully-organized inspection of dairies supplemented by good laboratory work should give. (Health officer Topeka, Kans. ) Very strict inspection would be necessary, and experience shows that to be often inefficient. (Straus Laboratory, Washington, D. C. ) A thorough physical test should be maintained. (John Thomas, Ednor, Md., president Milk Producers' Association.) Bacteriologists say the discovery of disease germs is speculative. Pasteuri- zation would not make it any safer. (Sharon Dairy, District of Columbia.) There are no tests applicable in cattle for typhoid or diphtheria, as cattle do not suffer from true or pseudo forms of typhoid or diphtheria, these dis- eases being of human type. The only safeguard in cases of this nature is proper and frequent sanitary inspection of all dairies and their surroundings, and scientific sanitary handling of the milk from cow to consumer. We pay the dairyman for his milk as if he delivered it, so as to remove any incentive to deliver milk while any person on his farm is ill with a contagious disease. (Borden's Condensed Milk Co., New York, N. Y.) I know of no tests for the different germs of disease that it would be prac- tical to apply. (Walker-Gordon Laboratory, Washington, D. C.) Cleanliness. (Dr. V. C. Vaughan, Ann Arbor, Mich.) I believe that constant inspection should be maintained, including exam- ination of farms, water supplies, cows, barns, utensils, and milk itself. (Dr. S. C. Prescott, Boston, Mass.) No. Have good sanitary inspection at dairies. (Health officer Los Angeles, Cal.) No. (J. M. Houston, White Cross Milk Co., Washington, D. C.) Yes; if it can be done practically. (Health officer San Francisco, Cal.) I think that strict rules regulating the handling of milk from the time it is milked until it reaches the consumer, and sufficient inspection to see that the rules are enforced, would accomplish more than any test. (Health officer St. ■Joseph, Mo.) 164 THE MILK SITUATION IN THE DISTEIICT OF COLUMBIA. No person with a contagious disease should be allowed to handle milk at any time. (Health officer Wheeling, W. Va.) I know of no test that would prove beneficial except a thorough system of milk inspection. (Dr. C. J. Marshall, University of Pennsylvania, Philadel- phia, Pa.) Question 10. — Assuming that the tuberculin test is indicative only of tubercu- lous conditions, are there any other tests which should he applied for the detection of typhoid, diphtheria, scarlet fever, or other germs? ANSWEBS. The tuberculin test only guards milk against infection with cattle tuber- culosis. It would still be necessary to take other precautions against the infection of typhoid fever, diphtheria, and other communicable diseases. Very few infectious diseases besides tuberculosis are communicable to people from cows. The danger of other diseases arises from contamination through the water supply or by persons handling the milk. There should be an occasional inspection of premises, attendants, methods of handling milk, etc., and an examination of the water supply. The families of those handling the milk should also be subjected to examination to guard against the spread of con- tagious diseases, and there should also be a requirement of compulsory notifi- cation of the health officer on the appearance of any contagious disease among attendants or their families. The score-card system of dairy inspection should be used. (Chief Bureau of Animal Industry.) Meaning of question not clear. Cows are not subject to typhoid fever and diphtheria. (Surgeon General U. S. Army.) There are no tests that could be applied for the certain detection of typhoid, diphtheria, and scarlet fever germs. (Surgeon General U. S. Navy.) The infection of typhoid fever, diphtheria, and scarlet fever does not come from the cow itself, but from those who milk the cow and handle the milk. Hence, provision against these infections should be made by inspection of the personnel of the dairy. (Surgeon General Public Health and Marine-Hospital Service. ) None worth while. Number of bacteria and presence of large numbers of colon bacilli of some value as indicating general conditions. (Dr. William H. Park, New York, N. Y.) Dairy hygiene with respect to typhoid, diphtheria, and scarlet fever carriers is the only efficient means of safeguarding the public against these infectious diseases. (Dr. Henry L. Coit, Newark, N. J.) Yes ; low bacterial count and clean conditions at dairy and healthy employees. (Dr. R. G. Freeman, New York, N. Y.) Inspection of premises and operatives at frequent intervals, cultures from throats of operatives, and numerical examination of milk, with microscopic examination of sediment, will go far to protect against other diseases. (Dr. M. P. Ravenel, Madison, Wis.) There are no practical tests. (Dr. C. E. A. Winslow, New York, N, Y.) Yes. (Health officer Ann Arbor. Mich.) The supervision of competent inspectors about the only safeguard. (Health officer Baltimore, Md.) There is not, so far as my knowledge goes. (Health officer Birmingham, Ala.) No. (Health officer Bismarck, N. Dak.) None which are practical. (Health officer Cleveland, Ohio.) Like No. 9, this question is vague; there is little or no question in the effi- ciency of the tubercular test. There is no like test for the detection of typhoid, diphtheria, etc. Besides, it is unnecessary to test for these diseases as they are not subject to them. (Health officer Columbus, Ohio.) Not specific. (Health officer Detroit, Mich.) No. (Health board State of Florida.) Culture tests, plating, etc. (Health officer Jacksonville, Fla.) Not to cow. This calls for a bacterial examination of milk which would give evidence of germs. (Health officer Kansas City, Mo.) Not that I ever heard of. (Health officer Lynchburg, Va.) Nothing practical to my knowledge, (Health officer Montclair, N. J.) None to my knowledge with reference to cows. The milk should be safe- guarded in other ways. (Health officer Portland, Oreg.) THE MILK SITTJATION IN THE DISTEICT OF COLUMBIA. 165 Standards of cleanliness of milk should be established, foreign substances should be prohibited, viz, filth, bacteria in excessive numbers, and proper tem- perature standards should be provided. (Health officer Providence, R. I.) No other tests possible that I know of. Competent inspection and insistence of rules and immediate study of all reported cases of these diseases (with reference to milk included) accomplish a great deal. (Health officer Rich- mond, Va.) None at present known, (Health officer Rochester, N. Y.) At this stage of bacteriological science efficiency and rapidity, examination ot the home where milk is produced and of those handling is the best method. In five years there will be no excuse for the existence of diphtheria and a bad excuse for the existence of scarlet fever. Both have been practically banished from this city. Typhoid fever is at very low ebb also. (Health officer Seattle, Wash. ) Careful, competent investigation of all cases. (Health officer Syracuse, N. Y.) Only such tests as a carefully organized inspection of dairies supplemented by good laboratory work should give. (Health officer Topeka, Kans.) Not to my knowledge. ( Sharon Dairy, Washington, D. C. ) As cattle do not suffer from typhoid, diphtheria, or scarlet fever, a more positive safeguard would be in all cases where there was reason to suspect that any of these diseases existed at a dairy whose product was regularly put on the market to make a reaction test from blood of the person suspected as having one of these diseases, either of typhoid or diphtheria, and who was con- nected with the dairy, by use of Widal's serum test for .typhoid and the isola- tion of Klebs-Lceffler bacillus for diphtheria. As to scarlet fever, it would have to be detected on presentation of clinical symptoms of the disease in the individual. These additional safeguards are sometimes resorted to as a pro- tection against the transmission of human diseases through milk. (Borden's Condensed Milk Co., New York, N. Y.) I know of no tests for the different germs of disease that it would be prac- tical to make. (Walker-Gordon Laboratory, Washington, D. C.) No. (Dr. V. C. Vaughan, Ann Arbor, Mich.) It is my belief that by suitable educational campaign the producers can be brought to feel their responsibility in part at least, so that they will report cases as above. Examination of the milk for intestinal organisms will mate- rially assist in this work. I know of no applicable method to cover all the question as asked. (Dr. S. C. Prescott, Boston, Mass.) No. (Health officer Los Angeles, Cal.) Proper pasteurization is the only practical test. (J. M. Houston, White Cross Milk Co., Washington, D. C.) Only where suspected contamination. Then typhoid or diphtheria may be found. With typhoid in milk, very difficult. (Health officer San Francisco, Cal.) I know of no test that would prove beneficial except a thorough system of milk inspection. (Dr. C. J. Marshall, University of Pennsylvania, Philadel- phia, Pa.) Bacteriological analysis. (Health officer Scranton, Pa.) EXTRACT FROM ANSWERS OF BORDEN'S CONDENSED MILK CO. The following conclusions are taken from the testimony of Dr. Theobald Smith, of the medical department of Harvard University, the man who first discovered that the bovine bacillus was different from the human bacillus, given in a case involving the propriety of the tuberculin test : As a result of my special study, I would like to formulate the following con- clusions as representing not only my own views, but those of a great body of scientific men on the question of the relation of milk to tuberculosis : 1. Bovine tuberculosis is not transmissible to man in the sejise of being more than a relatively rare source of tuberculosis. 2. The bacillus of bovine tuberculosis has not yet been demonstrated to be the cause of pulmonary tuberculosis, true phthisis, or consumption. 3. A cow reacting toward tuberculin, but which shows clinically no signs of disease, and whose udder is unimpaired, is not to be regarded as a source of infection to man. 4. By a clinically sound cow I mean one free from swellings of bones, joints, lymph nodes, or other soft parts ; from indurations of portions of the udder and 166 THE MILK SITUATIOISr IN THE DISTKICT OF COLUMBIA. the giving off of milk physically changed ; from repeated diarrhea and discharge from the vagina; from the rejiented distension of the rumen with gas; from cough and physical signs of lung disease, these pointing to tuberculosis. 5. Unless tubercle bacilli be present in an article of food, be it milk or flesh, such an article of food can not in any sense be considered a source of tubercular infection. 6. There must be a tubercular lesion of the udder in order that milk may be coiitiuninated with tubercle bacilli in sufficient numbers to be dangerous to man. 7. Even if a clinicallj^ sound cow shed tubercle bacilli in her feces, which is unlikely, the enforcement of proper rules governing cleanliness would eliminate infection from such an alleged source. 8. Tubercle bacilli can be discharged in feces only in advanced cases of the disease in which there are open foci in the lungs or in the throat or in the intestinal walls. Such cases would most likely be detected by clinical exami- nation. 9. The elimination from dairies of all clinically diseased cows or cows show- ing upon careful physical examination by competent and conscientious veteri- narians disease of the udder removes all danger of infection of which we can take cognizance under present conditions. 10. A careful periodical inspection of all dairies by competent veterinarians at proper intervals, with removal of cows affected, as stated under paragraph 9, is as ample a safeguard for the protection of the public health as we can look for for some years to come. The line of progress has been defined above. 11. Tuberculosis prevails in countries where dairy products are not used as extensively as in other countries. 12. New York, Boston, and other American cities, as well as British cities, are materially lowering their death rates from tuberculosis without such a drastic and premature ordinance as that under discussion, as the same has been explained to me. 13. There is at present no evidence that the bovine type of bacillus can be transferred and assume the human type in the human body. 14. The discharge of tubercle bacilli into the milk of cows may take place abundantly in udder tuberculosis. In a small proportion of manifestly tuber- culous cows without evidence of udder disease it may take place at times in very small, numbers. 15. The factor of bovine tuberculosis in the human malady is not of such importance that it should be permitted to imperil the proper execution of meas- ures designed to relieve and cure the strictly human disease, or divert attention from it as the chief evil. 16. The digestive tract is not the exclusive or even predominating portal of entry for pulmonary phthisis. It is highly probable that most cases are due to inhalation or aspiration. 17. In infants the bacilli probably gain entrance through all portals more easily than later in life, and the disease becomes more easily generalized. There are no rational grounds for believing that latency in infancy plays any apreciable rdle in the disease of later decades, but ingestion probably does play a much more important part in infantile tuberculosis, owing to habits and susceptibility of this period of life, than has been granted heretofore. 18. In view of the unsatisfactory conditions which have followed a compul- sory application of the tuberculin test, in the destruction of animals, attention has been diverted from tuberculin as a guide, and an effort has been made to eliminate only those animals which discharge tubercle bacilli. Pasteurization. Question 1. — At what temperature should pasteurization he accompUshedf ANSWERS. Pasteurization should be performed by heating the milk to not less than 140° F. for not less than 20 minutes and rapidly cooling it. For commercial operations it would perhaps be well to require either a slightly higher tempera- ture (145° F.), or a little longer time (30 minutes) in order to be on the safe side. The so-called " flash " process of commercial pasteurization is not regarded as reliable. (Chief Bureau of Animal Industry.) THE MILK SITUATION IN THE DISTEICT OF COLUMBIA. 167 Preferably at 150° F. for 20 minutes. (Surgeon General United States Army.) At 60° C. (140° F.). (Surgeon General United States Navy.) At 145° F. for 20 minutes. (Surgeon General Public Health and Marine- Hospital Service.) Between 140° and 158° F.; 140° to 145° F. for 20 minutes approved. (Dr. William H. Park, New York, N. Y. At 140° F. for 40 minutes, 155° F. for 30 minutes, 167° F. for 20 minutes, or 190° for 1 minute, and immediately cooled to between 40° and 50° F. (Dr. Henry L. Colt, Newark, N. J.) At 140° F. for 40 minutes. (Dr. R. G. Freeman, New York, N. Y.) At 145° F. for 20 minutes. (Dr. M. P. Ravenel, Madison, Wis.) At 145° F. for 20 minutes, or 150° F. for 15 minutes. (Dr. C. E. A. Winslbw, New York, N. Y.) At 150° F. (Health officer Ann Arbor, Mich.) We have tried pasteurization in Atlanta, Ga., and have found it worse than bad. For a city of this size we do not think it should be considered. (Health officer, Atlanta, Ga.) Not over 158° F. (Health officer Baltimore, Md.) At 162° to 165° F. (Health officer Birmingham, Ala.) At 60° C. (140° F,). (Health officer Bismarck, N. Dak.) Under ideal conditions, should be retained at a temperature of 155° F. for one- half hour. (Health officer Cleveland, Ohio.) See code, page 46. [Appendix G.] (Health officer Columbus, Ohio.) At 140° to 145° F. for 20 minutes, not above 150° F. (Health officer Detroit, Mich.) At 60° to 75° C. (140° to 167° F.) for 20 minutes. (State board of health, Florida. ) At 140° F. for 20 minutes. (Health officer Jacksonville, Fla.) Holding the temperature of milk 20 minutes at a temperature of 150° to 160° F., not a mere flash as some plants do. (Health officer Kansas City, Mo.) Only suspicious milk should be pasteurized. Pasteurization is done by dirty dairies because dirty milk will soon sour. It is best to have a clean dairy and not pasteurize. At 165° to 170° F. (Health officer Lynchburg, Va.) Look up any authority on pasteurization. Our information is from these authorities rather than from experience. (Health officer Montclair, N. J.) At 170° F. for 20 minutes. (Health officer Portland, Oreg.) At 158° F. and kept at this temperature for 20 minutes. (Health officer Providence, R. I.) Opinions differ greatly. (Health officer Richmond, Va.) At 140° F. for 30 minutes. This does not injure your cream line. (Health officer Seattle, Wash.) At 140° F. for 20 minutes. (Health officer Topeka, Kans') We are using 150° to 155° F. and holding the milk at that temperature for 20 minutes after it reaches it. (Straus Laboratory, Washington, D. C.) Authorities differ. Some say 145° F. and others 212° F. in order to make the milk sterile. (Sharon Dairy, District of Columbia.) Our Mr. Willman is the inventor of the pasteurizing process of heating milk continuously for 30 minutes at between 145° to 150° F. We have mentioned above that the Government is recommending this process, therefore we have nothing else to add. (Dairy Machinery & Construction Co., Derby, Conn.) At 145° F. for 30 minutes. (Creamery Packing Manufacturing Co., Chicago, HI.) At 212° for 10 minutes or 145° for 1 hour. (Borden's Condensed Milk Co., New York, N. Y.) I understand the temperature prescribed for so-called " perfect " pasteuriza- tion of 155° F. for 30 minutes. (Walker-Gordon Laboratory, Washington, D. C.) At 165° to 170°, (V. C. Vaughan, Ann Arbor, Mich.) At 155° to 165° F. (Dr. S. C. Prescott, Boston, Mass.) At 145° for 20 minutes. (Health officer Los Angeles, Cal.) At 140° from 30 minutes to 2 hours, and 30 minutes is considered sufficient. (J. M. I-Iouston, White Cross Milk Co., Washington, D. C.) From 60° to 70° C. (Health officer San Francisco, Cal.) At not above 150° F. (Health officer St. Joseph, Mo.) At 60° C. for 20 minutes. (Health officer Wheeling, W. Va.) At 142° F. for 20 minutes. (Dr. Samuel McC. Hamill, Philadelphia, Pa.) Between 140° and 175° F. (Health officer Scranton, Pa.) 168 THE MILK SITUATION IN THE DISTEICT OP COLUMBIA. Question 2. — Is pasteurization commercially practicaMef ANSWEES. Pasteurization is commercially practicable, but investigations made by the Bureau of Animal Industry show that it is not always reliable when left entirely to the dealers. Commercial pasteurization in order to be reliable should be under official supervision. (Chief Bureau of Animal Industry.) Yes. (Surgeon General U. S. Army.) Yes. (Surgeon General U. S. Navy.) Yes. (Surgeon General Public Health and Marine-Hospital Service.) Certainly. (Dr. William H. Park, New York, N. Y.) Only when under official direction, with apparatus that is approved by the medical authorities and operated by officers who are intelligent, above the grade of the ordinary laborer or employee. (Dr. Henry L. Coit, Newark, N. J.) Yes. (Dr. R. G. Freeman, New York, N. Y.) Yes. (Dr. M. P. Ravenel, Madison, Wis.) Yes. (Dr. C. E. A. Winslow, New York, N. Y.) Doubtful. (Health officer Ann Arbor, Mich.) Yes. (Health officer Baltimore, Md.) I do not think so. (Health officer Birmingham, Ala.) Yes. (Health officer Bismarck, N. Dak.) Only for the larger dealers. (Health officer Cleveland, Ohio.) Yes. (Health officer Columbus, Ohio.) Yes. (Health officer Detroit, Mich.) Yes. (Health officer Jacksonville, Fla.) Yes. (Health officer Kansas City, Mo.) Yes; but not advisable. (Health officer Lynchburg, Va.) Look up any authority on pasteurization. Our information is from these authorities rather than from experience. (Health officer Montclair, N. J.) Could be made so. (Health officer Portland, Oreg.) Yes. (Health officer Providence, R. I.) Entirely practicable, but likely to be utterly inefficient. (Health officer Richmond, Va.) No ; it is a device for the purpose of permitting men to sell quantities of milk unfit for human consumption. (Health officer Rochester, N. Y.) Doubtful. (Health officer Seattle, Wash.) No. (Health officer Syracuse, N. Y.) Yes. (Health officer Topeka, Kans.) So considered by men who ought to know. (Straus Laboratory, Washing- ton, D. C.) No. (Sharon Dairy, Washington, D. C.) Yes; with considerable modification of the present practice. (Borden's Con- densed Milk Co., New York, N. Y.) We have not had experience with pasteurization except as ordered by phy- sicians in the prescription feeding of infants. (Walker-Gordon Laboratory, Washington, D. C.) No. (Dr. V. C. Vaughan, Ann Arbor, Mich.) Yes. (Dr. S. C. Prescott, Boston, Mass.) Yes. (Health officer Los Angeles, Cal.) Yes. (J. M. Houston, White Cross Milk Co., Washington, D. C.) No. (Health officer San Francisco, Cal.) I do not think proper pasteurization very practical commercially. (Health officer St. Joseph, Mo.) Yes. (Health officer Wheeling, W. Va.) No. At least no method has been devised that is practicable. (Dr. Samuel McC. Hamill, Philadelphia, Pa.) Yes. (Health officer Scranton, Pa.) QtTESTiON 3. — What effect lias pasteurization upon the nutritive and digestive qualities of milkf ANSWERS. Pasteurization at the temperature above recommended has little or no effect on the nutritive and digestive qualities of milk ; certainly no deleterious results have ever been scientifically demonstrated. (Chief Bureau of Animal Industry.) THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 169 It has no injurious effect. (Surgeon General U. S. Army.) It slightly alters the nutritive as well as digestive qualities of milk. (Sur- geon General U. S. Navy.) If properly performed there is no proof that it has any deleterious effect on the nutritive and digestive qualities of milk. (Surgeon General Public Health and Marine-Hospital Service.) Very slight effect at 140° to 145°. (Dr. William H. Park, New York, N. Y.) Efficient pasteurization at the temperatures indicated does not destroy the digestive enzymes or nutritive principles in milk. (Dr. Henry L. Coit, Newark, N. J.) At above temperature (140° F. for 40 minutes) none. (Dr. R. G. Freeman, New York, N. Y.) It is doubtful if any change is caused. Some individuals do not thrive on pasteurized milk, but same is true of raw milk. (Dr. M. P. Ravenel, Madison, Wis.) No harmful effect whatever if done below 155°. (Dr. C. E. A. Winslow, New York, N. Y.) Detrimental. (Health officer Ann Arbor, Mich.) I think it has no effect. (Health officer Baltimore, Md.) There is much difference of opinion on this subject, some authorities claim- ing that it makes milk harder to digest, especially for infants and young children. (Health officer Birmingham, Ala.) Less nutrition and harder to digest. (Health officer Bismarck, N. Dak.) . Probably none if properly done. (Health officer Cleveland, Ohio.) Mooted question. (Health officer Columbus, Ohio.) Practically none. (Health officer Detroit, Mich.) None if milk is not heated over 140° F. (Health officer Jacksonville, Fla.) Has not been definitely decided, (Health officer Kansas City, Mo.) The effect on digestibility is bad. (Health officer Lynchburg, Va.) Look up any authority on pasteurization. Our information is from these authorities rather than from experience. (Health officer Montclair, N. J.) So slight that amounts to nothing. (Health officer Providence, R. I.) In itself, properly conducted, pasteurization probably has no effect on either. Commercial pasteurization, however, may affect both and it also encourages neglect of the care necessary to provide wholesome, safe milk. (Health officer Richmond, Va.) Probably slightly retards digestion. (Health officer Rochester, N. Y.) No one knows, so far as my knowledge goes. Opinions differ, although I believe the concensus of opinion is that it is slightly harder for infants to digest. One man says one thing and another another. (Health officer Seattle, Wash.) The vitality of milk is destroyed. (Health officer Syracuse, N. Y.) None. (Health officer Topeka, Kans.) > None. (Straus Laboratory, Washington, D. C.) ' It destroys the two most valuable nutritive qualities in the milk, namely, f.lbumen and lactic acid. (Sharon Dairy, District of Columbia.) From my experience with my own children, I never found that raw milk agrees better with them than pasteurized milk. (Dairy Machinery & Construc- tion Co., Derby, Conn.) If properly pasteurized at 145° F., there would be no difference. (Creamery Package Manufacturing Co., Chicago, 111.) Do not think that enough data has been collected to give us any positive data in regard to the nutritive or digestive value of milk after pasteurization com- pared with before, authorities disagreeing on this pont. (Borden's Condensed Milk Co., New York, N. Y.) I am told by a number of competent physicians that pasteurization destroys the self-digesting ferments or enzymes, and diminishes the nutritive value of milk. (Walker-Gorden Laboratory, Washington, D. C.) Slightly diminishes it. (Dr. V. C. Vaughan, Ann Arbor, Mich.) A much debated question. Apparently it is a question of the individual. (Dr. S. C. Prescott, Boston, Mass.) Very little effect. (Health officer Los Angeles, Cal.) If carried on at low temperatures, no effect. (J. M. Houston, White Cross Milk Co., Washington, D. C.) Decreases same. (Health officer San Francisco, Cal.) These are very important questions, and can hardly be answered in the space you allow. (Health officer Wheeling, W. Va.) 170 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. No definite answer can be given to this question. Clinical evidence in the form of nutritional diseases, more especially infantile scurvy, suggests it has a detrimental effect upon the nutritive value. (Dr. Samuel McC. Hamill, Phila- delphia, Pa.) None. (Health officer Scranton, Pa.) • Question 4. — What effect lias Pasteurization upon the beneficial and prejudicial germs in milk? ANSWERS. Pasteurization at the temperatures above recommended (140° F., 20 minutes, to 145° F., 30 minutes), while destroying most, if not all, of the pathogenic bacteria, will not destroy all of the lactic-acid bacteria ; hence milk so pas- teurized will sour normally. While certain germs are considered beneficial in butter making and cheese making and in the production of ripened or fermented milks, they can not be regarded as beneficial in sweet milk for ordinary use. The advantage of destroying injurious germs would greatly outweigh any pos- sible loss from the destruction of any germs that might be considered harmless. (Chief Bureau of Animal Industry.) It destroys all germs which do not multiply by spores. (Surgeon General U. S. Army.) It destroys all but spore bearers. (Surgeon General U. S. Navy.) Pasteurization, if performed as stated above (145° F. for 20 minutes), de- stroys pathogenic bacteria and does not destroy the ferments. (Surgeon Gen- eral Public Health and Marine-Hospital Service.) Kills all alike that are not in spore forms. (Dr. William H. Park, New York, N. Y.) Efficient pasteurization destroys all ordinary pathogenic bacteria and also most of the other contaminating germs. (Dr. Henry L. Coit, Newark, N. J.) Destroys most of the germs. (Dr. R. G. Freeman, New York, N. Y.) Doubtful whether there are any germs which are beneficial. Prejudicial germs are killed, except spore formers. (Dr. M. P. Raven el, Madison, Wis.) Destroys large proportion of all germs and all pathogenic likely to be present. (Dr. C. E. A. Winslow, New York, N. Y.) Equal. (Health ofiicer Ann Arbor, Mich.) Bacterial organisms are destroyed, but not all the beneficial germs. (Health officer Baltimore, Md.) It has practically the same effect on all germs present in milk, kills them, except certain spore-bearing germs. (Health officer Birmingham, Ala.) Destroys them. (Health officer Bismarck, N. Dak.) Retards their growth or destroys them, depending upon the degree of effi- ciency. (Health officer Cleveland, Ohio.) Friendly germs are more easily destroyed than prejudicial germs. (Health officer Columbus, Ohio.) Destroys all but spore bearers. (Health officer Detroit, Mich.) It kills them. (State Board of Health, Florida.) Destroys all nonsporing organisms. (Health officer Jacksonville. Fla.) Retards the development of germs. (Health officer Kansas City, Mo.) Done correctly; typhoid germs are killed and most others, probably. It is seldom done properly; uniformly. (Health officer Lynchburg, Ya.) Look up any authority on pasteurization. Our information is from these authorities rather than from experience. (Health officer Montclair, N. J.) If sufficient temperature, prevents growth. (Health officer Portland, Oreg.) Will kill all tuberculosis, diphtheria, typhoid, and most disease germs. (Llealth officer Providence, R. I.) There are no beneficial germs in good fresh milk. Lactic acid bacteria are beneficial in a negative way, as they sour milk and thus show it is old. Lactic acid bacteria are easily killed by pasteurization and thus this valuable sign (souring) may be done away with. Proper pasteurization should kill most prejudicial germs. (Health officer Richmond, Va.) Retards the growth or kills the first and does not interfere with the other, so as to give the absolute protection claimed. (Health officer Rochester, N. Y.) It destroys the beneficial germs, as it does largely the prejudicial. But the prejudicial germs come to the front and multiply with such rapidity that after a certain length of time this milk becomes absolutely dangerous. It is probably a wise makeshift, but never to take the place of good, clean, natural milk. (Health officer Seattle, Wash.) THE MILK SITUATION IN THE DISTEICT OP COLUMBIA. 171 Destroys the beneficial germs. (Health officer Syracuse, N. Y.) Destruction. (Health officer Topeka, Kans.) Pasteurization kills most of the germs. The temperature given above (150° F. to 155°, 20 minutes) destroys all disease germs that are found in milk. (Straus Laboratory, Washington, D. C.) It destroys the beneficial and does not kill the prejudicial. (Sharon Dairy, District of Columbia.) Pasteurization as a rule kills oif a certain form of pathogenic bacteria first. Then it attacks the lactic or so-called beneficial bacteria, and lastly the putre- factive organisms. This is particularly so when such putrefactive organisms are embedded or inclosed in excrement or some form of foreign matter v^here the heat does not readily penetrate and where to a great extent they are protected. (Borden's Condensed Milk Co., New York, N. Y.) Pasteurization does not destroy spores, but does destroy practically all of the lactic ferments which are credited by many authorities with holding in check many of the prejudicial germs, including those of decomposition. (Walker- Gordon Laboratory, Washington, D. C.) Kills all alike. (Dr. V. C. Vaughan, Ann Arbor, Mich.) Real pasteurization affects all in about the same degree. Commercial pas- teurization is noninjurious to certain harmful types. (Dr. S. C. Prescott, Boston, Mass.) Destroys pathogenic germs and majority of others. (Health officer Los Angeles, Cal. ) If the milk is bad to begin with, poor pasteurization may kill the beneficial germs, and as these keep the prejudicial germs from growing the prejvidicial germs grow unrestricted, and the milk is worse than raw milk. (J. M. Houston, White Cross Milk Co., Washington, D. C. ) Deleterious. (Health officer San Francisco, Cal.) It destroys the beneficial and some of the prejudicial. (Health officer St. Joseph, Mo. ) These are very important questions and can hardly be answered in the space you allow. (Health officer Wheeling, W. Va.) We do not admit that milk contains beneficial germs. Pasteurization, if prop- erly carried out, will destroy all so-called pathogenic organisms. (Dr. Samuel McC. Hamill, Philadelphia, Pa.) It destroys typhoid fever bacteria ; also destroys the virulence of tubercle bacillus. (Health officer Scranton, Pa.) Question 5. — Does pasteurization tend to preserve milkf ANSWERS. Yes. (Chief Bureau of Animal Industry.) It will for a limited period. (Surgeon General U. S. Army.) Only to the extent that it renders the milk temporarily sterile. (Surgeon General U. S. Navy.) Pasteurization is not intended to preserve milk, but to destroy pathogenic bacteria contained in it. (Surgeon General Public Health and Marine-Hospital Service. ) It does. (Dr. William H. Park, New York, N. Y.) Pasteurization does not preserve milk without efficient and constant refrigera- tion. (Dr. Henry L. Colt, Newark, N. J.) Yes; especially if done in the container in which it is kept. (Dr. R. G. Free- man, New York, N. Y.) Yes ; but the milk requires just as careful handling as before pasteurization. (Dr. M. P. Ravenel, Madison, Wis.) It does. (Dr. C. E. A. Winslow, New York, N Y.) Yes. (Health officer Ann Arbor, Mich.) To a slight extent. (Health officer Baltimore, Md.) Yes; for a given length of time. (Health officer Birmingham, Ala.) Yes. (Health officer Bismarck, N. Dak.) Yes. (Health officer Cleveland, Ohio.) Yes. (Health officer Columbus, Ohio.) Yes. (Health officer Detroit, Mich.) Till reinfected. A'fter that it deteriorates worse than raw milk. (State board of health, Florida.) Yes; if properly done. (Health officer Jacksonville, Fla.) 172 THE MILK SITUATION IN "THE DISTRICT OF COLUMBIA. To a certain extent. It tends to, retard growth of germs if promptly cooled afterwards and so maintained. (Health officer Kansas City, Mo.) Yes. (Health officer Lynchburg, Va.) Look up any authority on pasteurization. Our information is from these authorities rather than from experience. (Health officer Montclair, N. J.) Yes. (Health officer Portland, Oreg.) Yes. (Health officer Providence, R. I.) Yes. (Health officer Richmond, Va.) Yes, unfit milk. (Health officer Rochester, N. Y.) It will stay sweet for a greater length of time than if it had not been pasteurized. (Health officer Seattle, Wash.) No. (Health officer Syracuse, N. Y.) Yes. (Health officer Topeka, Kans.) Yes; by destroying germs in the milk the process of souring is retarded, (Straus Laboratory, Washington, D. C.) Yes. (Sharon Dairy, District of Columbia.) Certainly, as the lactic acid germs are destroyed. (Creamery Package Manu- facturing Co., Chicago, 111.) Pasteurization preserves milk for a certain length of time, and if it is prop- erly cared for it will keep a few weeks. The hospitals of the Panama Canal are supplied with perfectly pasteurized milk that runs through one of my machines at the Sheffield Farms, Slawson-Decker Co., of New York City, and this will give evidence enough that such pasteurized milk naturally has to keep, because without this it could not be shipped from New York to Panama and arrive there in perfect condition. (Dairy Machinery & Construction Co., Derby, Conn.) Only in so far as it renders the bacteria inactive, and pasteurized milk needs to be kept fully as cold, if not colder, than unpasteurized milk, unless pasteuri- zation has been carried to complete sterilization. (Borden's Condensed Milk Co., New York, N. Y.) Yes, against souring, but not necessarily against what may be much more objectionable organisms. (Walker-Gordon Laboratory, Washington, D. C.) Yes. (Dr. V. C. Vaughan, Ann Arbor, Mich.) Temporarily, yes ; i. e., it postpones souring, and, to a less degree, putrefac- tion. (Dr. S. C. Prescott, Boston, Mass.) Yes, if properly handled afterwards. (Health officer Los Angeles, Cal.) Yes; properly pasteurized milk will keep at least twice as long. (J. M. Houston, White Cross Milk Co., Washington, D. C.) Very little. (Health officer San Francisco, Cal.) As far as natural souring is concerned, yes. (Health officer St. Joseph, Mo.) Yes. (Health officer Wheeling, W. Va.) Not in our opinion. (Dr. Samuel McC. HamiU, Philadelphia, Pa.) Yes. (Health officer Scranton, Pa.) Question 6. — Do harmful germs multiply as rapidly in pasteurized as in raw milkf ANSWERS. Yes. Experiments have shown that there is practically no difference in the multiplication of germs in pasteurized milk and in clean raw milk of approxi- mately the same bacterial content and kept under similar conditions. While the rate of multiplication may be more rapid in pasteurized milk than in raw milk with a much higher bacterial content, this is because of the low number of bacteria in the pasteurized milk at the beginning of the test, so that the ratio of multiplication is much greater as compared with the raw milk in which the number of bacteria is already enormous. (Chief Bureau of Animal Industry.) Yes. (Surgeon General U. S. Army.) At least as rapidly. (Surgeon General U. S. Navy.) I am unable to give data on this. (Surgeon General Public Health and Marine-Hospital Service. ) About the same. (Dr. William H. Park, New York, N. Y.) More rapidly. (Dr. Henry L. Colt, Newark, N. J.) Probably. (Dr. R. G. Freeman, New York, N. Y.) Yes; perhaps more so. (Dr. M. P. Ravenel, Madison, Wis.) Yes. (C. E. A. Winslow, New York, N. Y.) THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 173 Under similar conditions. (Health officer Ann Arbor, Mich.) I do not know; it is said that they do. (Health officer Baltimore, Md.) It is my opinion that they do in case that the milk should receive a rein- fection. (Health officer Birmingham, Ala.) Yes. (Health officer Bismarck, N. Dak.) No. (Health officer Cleveland, Ohio.) Yes. (Health officer Columbus, Ohio.) Yes. (Health officer Detroit, Mich.) More rapidly in pasteurized milk, as raw milk has some germicidal prop- erties. (Health officer Jacksonville, Fla.) If milk remains at body temperature, multiply more so in raw milk. Milk is a perfect medium for bacterial growth. (Health officer Kansas City, Mo.) Yes; I believe so. (Health officer Lynchburg, Va.) Look up any authority on pasteurization. Our information is from these authorities rather than from experience. (Health officer Montclair, N. J.) Yes; but are delayed for a time by pasteurization. (Health officer Port- land, Oreg.) If dairies kept clean, no. (Health officer Providence, R. I.) More rapidly as a rule. (Health officer Richmond, Va.) More so. (Health officer Rochester, N. Y.) Much faster, in my opinion, after the milk is 48 hours old. (Health officer Seattle, Wash.) Theoretically, yes. (Health officer Syracuse, N. Y.) More so, especially if pasteurization be at all inefficiently done. (Health officer Topeka, Kans. ) Yes; if given a chance to get in after pasteurization. (Straus Laboratory, Washington, D. C.) Yes ; faster. Raw milk has germicidal properties. ( Sharon Dairy, District of Columbia.) Under advantageous conditions certain germs will multiply much more rapidly in pasteurized milk than in raw milk, due to the fact that in raw milk when it has reached a certain acidity certain forms will entirely cease to multiply, and most of the increase is due to harmless bacteria. This statement is made on the average bacterial content as regards variety of species and does not apply to special cases in which the harmful germs multiply much more rapidly than the ordinary lactic. The latter case, however, being rare, can almost be disregarded. (Borden's Condensed Milk Co., New York, N. Y.) A number of authorities claim more rapidly, owing to the absence of lactic acid forming bacilli which destroy many of the other organisms. (Walker- Gordon Laboratory, Washington, D. C.) Probably more rapidly. (Dr. S. C. Prescott, Boston, Mass.) Yes. (Health officer Los Angeles, Cal.) Yes; more so unless the pasteurization is proper and the milk produced properly at the farm. (J. M. Houston, White Cross Milk Co., Washing- ton, D.C.) Yes. (Health officer San Francisco, Cal.) Much more rapidly. (Health officer St. Joseph, Mo.) Yes. (Health officer Wheeling, W. Va.) Probably, yes; this depends to some extent upon the degree of heat. (Dr. Samuel McC. Ha mill, Philadelphia, Pa.) No. (Health officer Scranton, Pa.) QtTESTioN 7. — Are pasteurizing machines controlled, so far as you know, by a monopoly? ANSWERS. No; there are eight or ten pasteurizing machines on the market, and so far as the department knows they are independent. Certainly there is every appearance of strong competition in the sale of the different makes. (Chief Bureau of Animal Industry.) Not that I am aware. (Surgeon General U. S. Army.) None that we know of. (Surgeon General U. S. Navy.) I have no knowledge of any monopoly of pasteurizing machines. (Surgeon General Public Health and Marine-Hospital Service.) They are not. (Dr. William H. Park, New York, N. Y.) Not to my knowledge. (Dr. Henry L. Coit, Newark, N. J.) 174 THE MILK SITUATION IN THE DISTKICT OP COLUMBIA.^ Know nothing about this. (Dr. R. G. Freeman, New York, N. Y.) No. (Dr. M. P. Ravenel, Madison, Wis.) Not to my knowledge. (Dr. C. E. A. Wiuslow, New York, N. Y.) I do not know. (Health officer Baltimore, Md.) I do not know. (Health officer Birmingham, Ala.) Do not know. (Health officer Bismarck, N. Dak.) No. (Health officer Cleveland, Ohio.) Do not know. (Health officer Columbus, Ohio.) No. (Health officer Detroit, Mich.) No. (Health officer Jacksonville, Fla.) Not in kansas City. (Health officer Kansas City, Mo.) Don't know. (Health officer Lynchburg, Va.) I think not. (Health officer Portland, Or eg.) No; anyone can pasteurize milk in original package, i. e., bottles. (Health officer Providence, R. I.) I have never heard of such a monopoly. (Health officer Richmond, Va.) I don't know. (Health officer Rochester, N. Y.) We think so. (Health officer Seattle, Walsh.) Do not know. (Health officer Syracuse, N. Y.) No. (Health officer Topeka, Kans.) Not that I know of. (Straus Laboratory, Washington, D. C.) Indications point that way. (Sharon Dairy, District of Columbia.) There is absolutely no monopoly controlled by the sale or production of pas- teurizing machinery. All we know is that the different manufacturers light each other in the worst way for trade. (Dairy Machinery & Construction Co., Derby, Conn.) No; manufacturers of these machines are all independent of each other and in keen competition. (Creamery Package Manufacturing Co., Chicago, 111.) So many forms of pasteurizing machines are known that it would be very hard to have any control over them, as on many of the machines patents have expired, and it would be very easy for any manufacturing company to start manufacturing them, or dealer to manufacture his own. (Borden's Condensed Milk Co., New York, N. Y.) Not so far as I know. (Walker-Gordon Laboratory, Washington, D. C.) I do not know what " arrangements " exist between the different manufac- turers. (Dr. S. C. Prescott, Boston, Mass.) I do not know. (Dr. V. C. Vaughan, Ann Arbor, Mich.) Don't know. (Health officer Los Angeles, Cal.) No. (J. M. Houston, White Cross Milk Co.. Washington, D. C.) I do not know. (Health officer Wheeling, W. Va.) Unable to answer. (Dr. Samuel McC. Hamill, Philadelphia, Pa.) I don't know. (Health officer Scranton, Pa.) Question 8. — Is a municipal pasteurisation plant (or plants) in you?- judg- ment practicable and desirable? Yes. Dealers doing a large business and having proper equipment should be allowed to continue pasteurization at their own plants, but under official supervision. There should be a central municipal plant or plants at which the milk of all other dealers should be required to be pasteurized. Such a plan would have the advantage of bringing all milk under official supervision. ( Chief Bureau of Animal Industry. ) As to practicability, yes. As to desirability, I do not know. (Surgeon Gen- eral U. S. Army.) Yes. (Surgeon General U. S. Navy.) In my opinion, where thorough official supervision of private pasteurizing plants is not practicable, municipal plants should take their place. (Surgeon General Public Health and Marin-e-Hospital Service.) I believe in strict supervision and control, but not operation. (Dr. William H. Park, New York, N. Y.) Municipal pasteurization is impracticable and undesirable unless every quart of milk brought to a community is efficiently pasteurized at or near the source of production and properly refrigerated. This has not been accomplished thus far. (Dr. Henry L. Colt, Newark, N. J.) THE MILK SITUATION IN THE DISTKICT OF COLUMBIA, 175 Absolutely not. We want clean raw milk. The pasteurization can be done better in the home. (Dr. R. G. Freeman, New York, N. T.) Yes. If not municipal, strict and abundant inspection is necessary. (Dr. M. P. Ravenel, Madison, Wis.) Yes, unless commercial plants are carefully supervised. (Dr. C. E. A. Winslow, New York, N. Y.) No. (Health ofBcer Ann, Arbor, Mich.) No. (Health officer Baltimore, Md.) I have not given this subject enough thought to give a definite answer. (Health officer Birmingham, Ala.) No. (Health officer Bismarck, N. Dak.) » I am not prepared to say as yet. (Health officer Cleveland, Ohio.) It is desirable, but its practicability is problematic. (Health officer Colum- bus, Ohio.) Yes. (Health officer Detroit, Mich.) Not half so desirable as clean milk. (State board of health, Florida.) No. (Health officer Jacksonville, Fla.) Yes, providing your department has enough health inspectors. (Health officer Kansas City, Mo.) Might be practicable, but not desirable. (Health officer Lynchburg. Va.) Yes, for large cities, but not for small communities. Always get a good raw milk if possible. (Health officer Montclair, N. J.) I so recommended, but the newspapers would not stand for it. I think it practicable. (Health officer Portland, Oreg.) No. (Health officer Providence, R. I.) It furnishes, perhaps, the only means of securing efficient pasteurization of entire milk supply, if such is deemed necessary. Municipal inspection is next best thing, where all milk must be pasteurized. (Health officer Richmond, Va.) Some day they may be, but if that day ever comes pasteurization will be unnecessary. (Health officer Rochester, N. Y.) Yes. (Health officer Seattle, Wash.) No. (Health officer Syracuse, N. Y.) Yes. (Health officer Topeka, Kans.) Yes. (Straus Laboratory, Washington, D. C.) No. (Sharon Dairy, District of Columbia.) We believe that in the United States it is better to have individual pasteuriz- ing plants; that is, handled by individual concerns. (Dairy Machinery and Construction Co., Derby, Conn.) No. We do not believe that a proposition of this sort can be successfully and economically handled by municipal government. (Creamery Packing Manufacturing Co., Chicago, 111.) No. Neither practicable nor desirable, and absolutely disadvantageous in every way. (Borden's Condensed Milk Co., New York, N. Y.) I do not believe a municipal pasteurization plant would be either practical or desirable. (Walker-Gordon Laboratory, Washington, D. C. ) I am not sure. (Dr. V. C. Vaughan, Ann Arbor, Mich.) Yes; if pasteurization is to be made compulsory. (Health officer Los Angeles, Cal.) No. (J. M. Houston, White Cross Milk Co., Washington, D. C.) No. (Health officer San Francisco, Cal.) It would be desirable where clean milk is unobtainable, but I do not favor pasteurization of clean milk under any conditions. As to whether it would be practical or not, I do not know. (Health officer St. Joseph, Mo.) They should at least be under the control and regulation of the city. (Health officer Wheeling, W. Va.) Not unless there is developed some new method more constant in its results than those at present used. (Dr. Samuel McC. Hamill, Philadelphia, Pa.) Yes. (Health officer Scranton, Pa.) Question 9. — Should the plant (or plants) 6e located in the city or on the farm? ANSWERS. In order to have the pasteurization properly supervised the plant should be located in the city. (Chief Bureau of Animal Industry.) It would be difficult to supervise pasteurizatiou at farms. (Surgeon General D. S. Army.) " 176 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. In the city. (Surgeon General U. S. Navy.) .The location of the plant will depend on the city served, but it should be central. (Surgeon General Public Health and Marine-Hospital Service.) In the city or near by, so that it can be distributed vpithin a few hoursi after heating. (Dr. William H. Park, New York, N. Y.) Between the farm and city. (Dr. Henry L. Coit, Newark, N. J.) Never on the farm. (Dr. R. G. Freeman, New York, N. Y.) Better located as near the source of supply as possible. (Dr. M. P. Ravenel, Madison, Wis.) City. (Dr. C. E. A. Winslow, New York, N. Y.) They are better located on the farm, but probably will be confined to the city, or a creamery in the country. (Health officer Baltimore, Md.) On farm. (Health officer Bismarck, N. Dak.) City. (Health officer Cleveland, Ohio.) In the city. (Health officer Columbus, Ohio.) City. (Health officer Detroit, Mich.) It would be better, but not practical, on the farm. (Health officer Jackson- ville, Fla.) City. (Health officer Kansas City, Mo.) City. (Health officer Lynchburg, Va.) Depends on conditions. (Health officer Montclair, N. J.) * In the city. (Health officer Portland, Oreg.) City. (Health officer Providence, R. I.) A central plant in each neighborhood is the ideal thing if pasteurization must be done. (Health officer Richmond, Va.) City; if to be practicable. (Health officer Seattle, Wash.) In the city. (Health officer Syracuse, N. Y.) In city. (Health officer Topeka, Kans.) To save plants, in town. (Straus Laboratory, Washington, D. C.) Neither. (Sharon Dairy, District of Columbia.) That would depend entirely upon the local conditions, as to the time milk was received and time shipped. (Borden's Condensed Milk Co., New York, N. Y.) While it would be more desirable to pasteurize milk as soon as possible after it is drawTi from the cow, so much of the milk of commerce is produced on small farms where this work would not be properly performed, that it would seem more practical to have it done by the city dealers. (Walker-Gordon Laboratory, Washington, D. C.) On the farm. (Dr. V. C. Vaughan, Ann Arbor, Mich.) Will have to be central. (Health officer Los Angeles, Cal.) The plants should be located in the country by the railroads where the work is done near the source of supply, and not in the city after the milk is 12 to 24 hours old. (J. M. Houston, White Cross Milk Co., Washington, D. C.) Depends on environment. (Health officer San Francisco, Cal.) It would be better if they were located on the farm, provided a competent official could be in charge of the work. (Health officer St. Joseph, Mo.) Either place. Under proper regulations. (Health officer Wheeling, W. Va.) If established, they should be as near the consumer as possible. (Dr. Samuel McC. Hamill, Philadelphia, Pa.) City. (Health officer Scranton, Pa.) Question 10. — Is it possible hy scientific observation to ascertain definitely whether milk has been properly pasteurized or "lot? ANSWERS. The bacterial count is a good index of the efficiency of the pasteurization. (Chief Bureau of Animal Industry.) Yes. (Surgeon General U. S. Army.) Yes. (Surgeon General U. S. Navy.) No ; except by a bacterial examination of the milk before and after pasteuri- zation, which will show the consequent decrease in the number of bacteria. (Surgeon General Public Health and Marine-Hospital Service.) Probably only by observation of the process, or bacterial counts before and after heating and bottling. (Dr. William H. Park, New York, N. Y.) [ THE MILK SITUATION IIT THE DISTRICT OP COLUMBIA. 177 Not without expensive equipment of a laboratory and an expert investigator. The time necessary would defeat the object of the investigation, as the milk would have been already used. (Dr. Henry L. Coit, Newark, N. J.) It is easy to ascertain whether it is as sterile as it should be after pasteuri- zation. (Dr. R. G. Freeman, New York, N. Y.) No. (Dr. M. P. Ravenel, rJiadison, Wis.) Yes. (Dr. C. E. A. Winslow, New York, N. Y.) I think so. (Health officer Baltimore, Md.) Yes. (Health officer Birmingham, Ala.) No. (Health officer Bismarck, N. Dak.) Yes. (Health officer Cleveland, Ohio.) Not unless heated to 180° and determined by Storch's method. (Health officer Columbus, Ohio.) Yes. (Health officer Detroit, Mich.) Yes; test for enzymes. (Health officer Jacksonville, Fla.) Yes, if the relation of the component parts of milk stand as normal before pasteurization. (Health officer, Kansas City, Mo.) Only with great difficulty, if at all. Impracticable. Bacteria count would be lowered by pasteurization. Storch's test shows when heated to 176° F. (Health officer Lynchburg, Va.) Only by microscopical or bacterial examination. (Health officer Montclair, N. J.) Time would teU, but this would not be practical. (Health officer Portland, Oreg.) Yes. (Health officer Providence, R. I.) No absolute means so far as I know. If it is known that a given sample lias been pasteurized and if the sample contains very few bacteria, it may be assumed that the pasteurization has been efficient. The best test is to com- pare bacterial counts before and after pasteurization. This would, of course, be impossible of application to a single sample. (Health officer Richmond, Va.) I do not know. Several schemes have been proven failures. Dr. Evans of Chicago can give you data on this point if anybody can. He is the commissioner of health. (Health officer Seattle, Wash.) Yes. (Health officer Syracuse, N. Y.) Yes. (Health officer Topeka, Kans.) I know of no way except the bacterial count. (Straus Laboratory, Washing- ton, D. C.) Not to my knowledge. (Sharon Dairy, District of Columbia.) Yes. (Borden's Condensed Milk Co., New York, N. Y.) It is possible, but the results could not be known in time to be of practical value as to any given shipment of milk. (Walker-Gordon Laboratory, Wash- ington, D. C.) Yes. (Dr. V. C. Vaughan, Ann Arbor, Mich.) Yes. (Dr. S. C. Prescott, Boston, Mass.) Yes. (Health officer Los Angeles, Cal.) Yes. (J. M. Houston, White Cross Milk Co., Washington, D. C.) Not absolutely. (Health officer San Francisco, Cal.) It is possible, but not very practical on a large scale. (Health officer St. Joseph, Mo.) Yes. (Health officer Wheeling, W. Va.) Opinions differ as to this point. We know of no reliable method. (Dr. Samuel McC. Hamill, 'Philadelphia, Pa.) Question 11. — Would pasteurisation, if generally insisted upon, dispense with the necessity of the tuberculin test? While pasteurization is an efficient means of guarding against infection of milk, it should not be regarded as a substitute for other measures to eliminate disease. The tuberculin test has an important function in eradicating tuber- culosis of animals for the economic benefit of the live-stock industry and for the conservation of the supply of milk. Tuberculosis reduces the yield of milk, and the unrestricted spread of this disease would in time seriously curtail pro- duction. It is important, therefore, in the interest of a plentiful supply of milk, 82444°— S.

Dear Sir: In further reply to your letter of the 24th to Dr. Melvin, in his absence I take pleasure in inclosing answers to the supplemental questions sub- mitted by your committee. Very truly, yours, A. M. Fabrington, Acting Chief of Bureau. supplemental data requested by special committee of the WASHINGTON chamber OF COMMERCE APPOINTED TO INVESTIGATE THE PRESENT MILK SITUA- TION IN THE DISTRICT OF COLUMBIA. 1. Kindly furnish, if practicable, a generalized statement in a few words of the history of Federal inquiry into the production and distribution of milk? Prior to the establishment of the Dairy Division of the Bureau of Animal Industry in the United States Department of Agriculture on July 1, 1S95, the Federal Government had given very little attention to the subject of milk pro- duction. As early as 1893, however, following the discovery of tuberculin and the development of the tuberculin test, the Bureau of Animal Industry prepai'ed tuberculin for distribution free of charge to public health officers, with a view to restricting and eradicating tuberculosis of cattle. This distribution and use of tuberculin has been continued ever since to a steadily increasing extent. About the same period the bureau also began to study the subject of pasteuri- zation and issuing literature on this subject. Following the establishment of the Dairy Division active work dealing with the production and distribution of milk was undertaken, and in 1900 there was published a paper entitled " Market Milk : A Plan for its Improvement." This paper was issued to meet frequent requests for advice regarding improvement of the milk supply of cities and towns. The plan in brief was the creation in each community of an unofficial milk commission to inspect dairies and methods of producing and handling milk and to prescribe proper requirements govern- ing these things. The proposed arrangement was to be purely voluntary, the dairymen who conformed to the conditions being given certificates which would enable them to obtain business. The Bureau of Animal Industry has for several years done much to promote and introduce thef score-card system of dairy inspection, which has been found to be a valuable agency for improving the wholesomeness of milk supplies. This system was first introduced and used by Dr. William C. Woodward, health officer of the District of Columbia, early in 1904, and has since been modified, improved, and extended. In recent years the Bureau of Animal Industry has worked in various ways to bring about improvement in the wholesomeness of milk. It has made scientific investigations regarding tuberculosis, pasteurization, and other sub- jects ; it has studied practical methods of dairying, with a view to helping dairymen to improve their methods for the benefit of both producer and con- sumer; it has cooperated with numerous cities and towns in the improvement of their milk supplies ; it has furnished tuberculin to public-health officers and has applied the tuberculin test to a large number of cows ; it has studied the milk supplies of various cities and the methods of producing, transporting, handling, and delivering milk ; it has promoted competitive exhibitions of milk and cream to encourage the production of wholesome products, and has given THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 237 numerous lectures and addresses at public meetings; and it has prepared and distributed a large quantity of literature relating to the various phases of the milk question. 2. Is ihe feeding of " tvet malt " or other Tyrewery products to cows prejudicial to mine derived from them? The feeding of wet malt to cows has a deleterious effect upon the milk derived from them. Wet malt under certain prescribed conditions, however, may be safely used to a limited extent. Brewery products other than wet malt are not believed to be injurious to the milk, especially if they are fed in dry form. 3. Is the colon bacillus responsible for ■ other diseases besides diarrheal disorders? ■ The colon bacillus has often been found to be the active cause of appendicitis, chronic peritonitis, and abscesses of the liver. It is frequently found asso- ciated with other bacteria in cases of cystitis and in cases of fat necrosis, but has not been proved to be the primary invader. ^. Has ihe Bureau of Animal Industry or the Bureau of Chemistry of the Department of Agriculture prescribed any requirements for the improvement of methods of producing or selling milk transported from one State to another, either under authority of the food and drugs act of 1906 or otherwise? The Bureau of Chemistry has prescribed the following requirements for market milk in interstate commerce: It must be the fresh, clean, lacteal secretion obtained by the complete milking of healthy cows, properly fed and kept, excluding that obtained within 15 days before and 10 days after calving, and must contain not less than 8.5 per cent solids not fat, and not less than 3.25 per cent of milk fat. Bacteriologically it must not contain more than 500,000 bacteria per cubic centimeter for market milk ; not more than 100,000 for inspected milk ; not more than 10,000 for certified milk. The kind of bacteria present may modify judgment as to its quality. When practicable, sanitary inspection of dairies and creameries furnishing the product is also taken into consideration in enforcing these standards. 5. Has it been conclusively demonstrated that pathogenic microorganisms survive and retain their virulence hi butter, cheese, and other milk products? Pathogenic microorganisms will live in butter and cheese for several months. 6. Is there consequent reason for requiring that these products be maintained at low temperature; and if so, what maximum temperature should be main- tained? While low temperatures retard and inhibit the -growth and mutiplication of pathogenic germs, they can not be relied upon to destroy such germs. The require- ment that dairy products be held at low temperatures therefore would not remove the danger. Such contaminations should be guarded against and prevented so far as possible in the preparation of the products. The pasteurization of cream or milk before they are made into butter or cheese is considered the best method of accomplishing this object. United States Department of Agriculture, Bureau of Chemistry, Washington, D. C, November 30, 1910. Committee on Milk Investigation, Washington Chamber of Commerce, 1202 P Street NW., Washington, D. C. Gentlemen : I have your communication of the 24th instant asking my opinion on certain questions in regard to milk. I will reply as fully as I can. 1. The only regulations which have been formulated respecting the prepara- tion or distribution of condensed, modified, powdered, or evaporated milks are those contained in the standards of purity for food products, Circular 19, issued by the Secretary of Agriculture in- harmony with the authority of Congress, and they are as follows: (1) Milk is the fresh, clean, lacteal secretion obtained by the complete milking of one or more healthy cows, properly fed and kept, excluding that obtained within 15 days before and 10 days after calving, and contains not less than 8.5 per cent of solids, not fat, and not less than 3.25 per cent of milk fat. (2) Blended milk is milk modified in its composition so as to have a definite and 'Stated percentage of one or more of its constituents. 238 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. (3) Skim milk is milk from which a part or all of the cream has been removed, and contains not less than 9.25 per cent of milk solids. (4) Pasteurized milk is milk that has been heated below boiling, but suflB- ciently to kill most of the active organisms present, and immediately cooled to 50° F. or lower. (5) Sterilized milk is milk that has been heated at the temperature of boiling water or higher for a length of time sufficient to kill all organisms present. (6) Condensed milk — evaporated milk — is milk from which a considerable portion of water has been evaporated and contains not less than 28 per cent of milk solids, of which not less than 27.5 per cent is milk fat. (7) Sweetened condensed milk is milk from which a considerable portion of water has been evaporated and to which sugar (sucrose) has been added, and contains not less than 28 per cent of milk solids, of which not less than 27.5 per cent is milk fat. (8) Condensed skim milk is milk from which a considerable portion of water has been evaporated. (9) Buttermilk is the product that remains when butter is removed from milk or cream in the process of churning. (10) Goat's milk, ewe's milk, etc., are the fresh, clean, lacteal secretions, free from colostrum, obtained by the complete milking of healthy animals other than cows, properly fed and kept, and conform in name to the species of animal from which they are obtained. (1) Cream is that portion of milk, rich in milk fat, which rises to the surface of milk on standing, or is separated from it by centrifugal force, is fresh and clean, and contains not less than 18 per cent of milk fat. (2) Evaporated cream — clotted cream — is cream from which a considerable portion of water has been evaporated. ' 2. I am of the opinion that there is a wide variation of ideas which may be properlj^ entertained concerning " prepared " milk. I am inclined to the fol- lowing: Natural milk, which has not been treated other than by straining, cool- ing, and bottling, would not be entitled to the term " prepared milk." All milk which has been modified in its composition in any way, by changing the properties of its ingredients or by sterilization or pasteurization, should be designated as prepared milk. Milk which is used in connection with other foods in a dried or semiliquid state is not prepared milk but milk used in compound- ing other foods. 3. While I have not made experimental determinations on the effect of freez- ing milk, I am of the opinion that it profoundly modifies its character, perhaps not so much in regard to its potability as to its wholesomeness and nutritive qualities. My belief in this matter is based on the well-known fact that the freezing of wine or beer, or of meat or fruits, profoundly affects their character. I'or this reason milk, especially if intended for the nutrition of infants, should never be frozen. 4. I am unable to give the commission any information respecting the c(»m- parative retail prices of condensed, powdered, evaporated, and modified milks as compared with raw milk. I will say, however, that I do not believe that milk should have the prefix " raw " attached to it. The term " milk " means pure, fresh, clean, and properly handled milk, and the term " raw " is unneces- sary and discriminatory. 5. I do not believe that any milk which has undergone any so-called prepara- tion or modification of any kind is as wholesome and nutritious as the pure article. In my opinion pasteurization seriously injures milk in its nutritive value, especially for infants, and milk should never be pasteurized except as a choice between two evils. Insanitary milk, if used at all, should undoubtedly be pasteurized. Dirty milk is just as dirty after pasteurization as it was before. Pure, clean, properly handled milk needs.no pasteurization and no modifica- tion, and no preparation, except as indicated in the modifications of milk under proper medical control and advice for the feeding of infants. I use the term " milk " solely as the lacteal secretion of the cow and do not refer to mothers' milk, or the milk of sheep, goats, or asses. In my opinion large cities, and in that I include Washington, might be able to get a much better milk supply than is now afforded by the establishment of clean, sanitary milk plants in regions devoted to the dairy industry, drying the milk to a powder by one of the modern sanitary processes and transporting it to the city THE MILK SITUATIO]Sr IN THE DISTRICT OP COLUMBIA. 239 for speedy consumption. I would not, however, advise the use of milk powder by any means for infant feeding. I strongly urge upon every municipality to establish a milk plant under the direct control of the municipality where pure, clean, wholesome, unpasteurized, unmodified, and unprepared milk may be kept for the use of those infants who are fed artificially. I would have in this plant a modifying chamber under the direction of a competent specialist to modify the pure milk without any other change to as nearly the composition of fresh mothers' milk as possible, or to make special modifications of milk, under the direction of a physician, for those who are diseased. I would make it a penal offense for any person feeding an infant artificially to use any other food than that supplied from this central establishment. As far as grown people are concerned, in my opinion, a properly prepared milk such as I have described as coming from a distance can be used with safety and without danger of interfering with the nutritive processes. The municipal milk supply, therefore, would be only for the use of infants artificially fed. Respectfully, H. W. Wiley, Chief.

Gentlemen : Inclosed, I return herewith answers to certain of the questions sent out.

Very truly, yours, Joseph Y. Porter, State Health Officer. Office of Board of Health Commissioners, Bureau of Vital Statistics, Hartford, Conn., Novem'ber 10, 1910. Washington Chamber of Commerce, Washington, D. C. Gentlemen : I am in receipt of your questionaire relative to the control of production and handling of milk. The questions appear to me to be so diffuse as to render impossible the categorical answers which you evidently expect The ground covered by each of the questions is so broad that to my mind it is impossible to give the answers without a large number of exceptions. Such being the case I am sending you a copy of the Connecticut State law and our municipal ordinances on the subject. Very truly, yours, C. P. Botsford, Superintendent. Office of Health Officer, Lynchburg, Va., 'November 9, 1910. Chairman Committee on Milk Situation, Chamber of Commerce, Washington, D. C. Dear Sir : I inclose you blanks filled out as you requested. I believe that the great thing necessary in milk supply is instructive inspection. It is true that the inspector must be clothed with power to get rid of those who won't respond to reasonable demands, but only a few have been found here who had to be closed out. There is no compulsory tuberculin test here, but a number of dairymen have of their own accord had their herds tested, and all of them are interested and mostly making arrangements to test. This is a highly desir- able condition and is ripe for a law for those few, if any exist, who will not soon test. The dairymen here have the idea that the test is for the protection of their own herds more than for anything else. Yours, very truly, MosBT G. Perrow, Health Officer. 240 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. Department of Public Health and Charities, Philadelphia, December 8, 1910. J. Louis Willige, Esq., Chaitman Milk Committee, Washington Chamber of Commerce, Washington, D. G. Deab Sir: The Philadelphia milk conimission, which has been making a study of the milk problem in Philadelphia, has not as yet made its report. When such has been received I will be pleased to take up with you the questions men- tioned in your letter of recent date. This commission is going into the matter extensively and I feel that its findings will be of great importance to the city of Philadelphia. Very truly, yours, J. S. Neff, Director. Department of Health and Sanitation, Seattle, Wash., November 21, 1910. The Washington Chamber of Commerce, Washington, D. G. Gentlemen : Please find inclosed answers in full to questions submitted. You must realize that I am 3,000 miles away from Washington and laboring under somewhat different conditions, but I have answered the questions as it seems to me they should be answered in a district in which we have practically an all-year's outdoor pasturage, and in a district in which we have no very hot weather. You will notice that a tone of antagonism runs through my answers in refer- ence to pasteurization. I hardly know what I would do were I commissioner of health in a hot, eastern city. I am satisfied, however, that I would regard it only as a makeshift and would oppose it with all my strength and manhood as a permanent proposition, since I believe that it would be an insult to the intelligence of civilized men to admit that, with all our skill and canning, we can not produce a good wholesome milk just as God Almighty made it, unmodi- fied by man. If pasteurization shall be unnecessarily adopted in any com- munity and for any greater length of time than is absolutely necessary, I be- lieve that it will put back the time when we can expect to see safe milk pro- duced many, many years. In other words, by pasteurization the milk can be taken to a city and sold containing such contamination originally as would have condemned such milk had it not been pasteurized. Therefore the stimulus to produce milk without contamination has been removed and the tendency will be, without the slightest doubt, to deteriorate the standard of excellence from day to day and from year to year. Look at the difference in the quality of milk in most American cities to-day as compared to what it was, say, five years ago. Think of the swill-fed dairies of Cincinnati ; then realize what has been accomplished without pasteurization and think what may be accomplished during the next 10 or 20 years. In the meantime, however, under carefully drawn lines, pasteurization will save many lives. Yours, very truly, ' J. E. Crichton, Commissioner of Health. Department of Public Safety, Syracuse, November 11, 1910. Mr. Thomas Grant, Secretary Chamber of Commerce, Washington, D. G. Dear Sib : I have answered the questions to the inclosed circular letter to the best of my ability. The answers to many of the questions have been made off- hand, and so may be of little value to you. We have been carrying on an extensive milk campaign here in Syracuse for some four years, and we have done a great deal along the line of betterments in our milk supply. We are far from perfection in all of this work' The problems are very great, and many of them difficult of solution. Our aim has been to lessen the infant mortality in our city. We feel that something has been done in this line, but much still remains to be done. If you can give us any helpful suggestions from your studies and investigations, we should be very glad to get them. Yours, very truly, D. M. ToTMAN, Health Officer. THE MILK SITUATION IN THE MSTRIOT OF COLUMBIA. 241 Depabtment of Health, Wheeling, W. Va., November 14, 1910. The Washington Chamber of Commerce, Washington, D. C. Gentlemen : I have tried to answer the list of questions you submitted, but In some instances it is impossible to answer in a few words. We have tried to make our people understand that clean raw milk from healthy cattle is far preferable to pasteurized milk. We try to make them understand that bacteria grow perhaps more rapidly in pasteurized milk than in raw milk, and therefore pasteurized milk requires the same amount of care. We tell them that in a city where the milk supply is as close as Wheeling's there is no excuse for pasteurized milk. Some of our dairymen can and do bring in practically perfect milk. Why shouldn't the others do the same? In a large city where the milk supply comes from a great distance the situa- tion is different. Our newspapers print our milk reports, and we are thus able to bring this before the people. Yours, truly, W. H. McLain, M. D. Kensington, Md., November 10, 1910. J. Lotris Willige, Esq., Washington Chamber of Commerce, Washington, D. C. Dear Sir : I am inclosing herewith short answers to most of the questions submitted on the subject of the tuberculin test. I confine myself to one list of questions, as that has been my work abroad for a number of years. Should you care to request further information on the tuberculin test it will give me great pleasure to answer any questions or to appear before your committee personally, if they so desire. Very respectfully, T. A. Geddes. Philadelphia, December 28, 1910. Mr. J. Louis Willige, Chairman Washington Chamber of Commerce, Washington, D. C. Dear Sir : I herewith return the questionnaire which you sent me some weeks ago. I have answered the questions as intelligently as possible. The ones relating to the tuberculin tests I turned over to Dr. C. J. Marshall, of the veterinary department of the University of Pennsylvania, whom I consider the best- qualified person I know to answer such a series of questions. The replies attached are his. If the answers given will prove of any benefit to you it will be very gratify- ing both to Dr. Marshall and myself. Very truly, yours, S. McC. Hamill. Wisconsin State Hygienic Laboratory, Madison, November 19, 1910. Chairman of Milk Committee, 1202 F Street NW., Washington, D. C. My Dear Sir : Your circular letter inclosing several lists of questions were received on my return recently from Europe, and I take pleasure in giving answers. Many of these questions are general in character and almost impossible to answer without taking consideration of modifying circumstances. I have, how- ever, given as sur,cinct answers as possible, and beg you to remember that much more could be said on practically all of them. However, as an expression of opinion, I judge you wish the answers put as briefly as possible. The general 82444°— S. Doc. 863, 61-3 16 242 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. questions from 13 to 23 I have not replied to, partly because most of them come more directly under men enj^aged in other lines of work than my own, and partly because nuich can be said in answer to each question, so much de- pending on circumstances. For instance, question 13, " What is condensed milk?" There are a number of ways of condensing milk, as you no doubt know. A milk preserved by the addition of much sugar would be susceptible to changes entirely ditrerent from that simply condensed, but to which no sugar has been added. The same consideration is api)licable in regard to the nutri- tive qualities and digestibility and keeping qualities of such milks, much de- pending on circumstances, so that I do not feel able to answer these questions in the space allot1(>(l. However, as said before, you can get very much better opinions from men who are especially engaged in this line of work. I am, with high regard, very sincerely, yours, Mazyck p. Ravenel. Massachusetts Institute of Technology, Boston, November 9, 1910. Dear Sir : I am sorry that I have no time to study and make careful answers to the iutor(>sting questions which you lay before me. Having been absent from my desk for six months in Europe, I am now over- whelmed with work and regret that I shall not be able to assist you. Very truly, yours, W. T. Sedgwick. Chairman Chamber of Commerce, Washington, D. 0. Harvard University Medical School, Boston, Mass., November 15, 1910. The Washington Chamber of Commerce, Washington, D. C. Dear Sir: I have duly received your circular letter and accompanying series of questions dealing with the problem of dairy sanitation. On looking over the questions I find it impossible to give any categorical answers to them. My own views are more or less determined by opposing considerations and I should be giving an erroneous impression if I were to answer them briefly. I am sure that a few men in Washington holding fairly conservative views could furnish the desired information, since there are no widely divergent opinions among scientists at the present time on the subjects you have introduced. Very truly, yours. Theobald Smith. University of Minnesota, Minneapolis, Minn., December 1, 1910. Washington Chamber of Commerce, Washington, D. C. Gentlemen ; Immediately upon receipt of your blanks I set about trying to formulate answers which would be of use to yon. There were so many ques- tions, however, that I did not know quite what to do. Upon some of them my opinion would he purely academic; on certain others I felt a right to express an opinion, but it appeared to be quite impractical for me to contribute anything which would be of real use to you. You have in Washington, in your medical health officer, and in the various Federal services, including the United States Public Health and Marine-Hospital Service and the various divisions of the Departenmt of Agriculture, men whose opinions have the greatest weight with sanitarians throughout this and other coun- tries. In addition to their genei-al knowledge, they have specific information with- out which it would be inipossil)le to discuss intelligently tlie Washington situation. Outsiders, no matter how much they know about a subject in general, are at a disadvantage in d*\-iling wilii a local situation, and, instead of being helpful, might be i)ositively detrimental. Your blanks are comprehensive, but they should be filled out by those who see all sides of the local situation and are familiar with local conditions. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 243 In answer to yours of November 28, I have to say that I believe you have, right on the grounds in Washington, all the necessary authorities and should be able to receive a complete report upon the local situation which would form the basip of action which would be at once suitable to the needs of Washington and prove of profit to the rest of us in the solution of our own local problems. I should be glad to be of help in any way possible, but feel personally that this letter is the best help that I can give you. Yours, very truly, F. F. Wesbbook. The College of the City of New York, tfew York, November 17, 191.0. Washington Chamber of Commerce, Washington, D. C. Dear Sirs : I inclose replies to as many of the questions in your excellent set of papers on milk supply as I felt that I could answer. If the results of this questionnaire are published, I should be very glad to receive a copy of it, as I should think they would be of great value. Sincerely, yours, C. E. A. WiNSLOw. Borden's Condensed Milk Co., New York City, November 10, 1910. Washington Chamber of Commerce, 1202 F Street NW., Washington, D. C. Dear Sirs : This is to acknowledge receipt of your communication of the 1st instant, with inclosures, and to say that we will be glad to answer the various questions, as far as possible, as soon as we can find an opportunity to get the data together. Very truly, yours, Borden's Condensed Milk Co., F. J. Taylor, President. Borden's Condensed Milk Co., New York City, November 30, 1910. The Washington Chamber of Commerce, 1202 F Street NW., Washington, D. C. Dear Sirs : Referring to your favor of the 28th instant reminding us of your previous communication, would say that if you have made very much of an examination of the milk question you certainly are aware that it is an in- tricate one. We do not wish to make any haphazard, or premature answers to the questions which you have so intelligently compiled, and, considering the vast amount of general misinformation circulated on the milk question and the premature conclusions in some quarters, we felt that the inquiry which you had in hand was a movement along the right line, for it is time that the public itself, and the consuming public in particular, be informed more correctly on some of the phases of the milk question that seem to be debatable. Our stand- [loint is that the so-called milk question involves the producer, distributor, and consumer, and, therefore, can not be intelligently considered unless these factors are properly investigated. We expect to have the report ready in a few days and will forward to you promptly. Very truly, yours, Borden's Condensed Milk Co., F. J. Taylor, President. Borden's Condensed Milk Co., New York City, December 5, 1910. Washington Chamber of Commerce, 1202 F Street NW., Washington, D. C. Gentlemen : Supplementing our exchange of correspondence on this question, we herewith hand you our memorandum of replies to the questions presented in your request. Our answers are based upon an earnest desire to view the 244 THE MILK SITUATIOK IN THE DISTRICT OF COLUMBIA. whole subject from the practical standpoint of recognizing the dependency of the consumer upon the producer and the necessity of the distributor, for it goes without saying that the individual consumer can not go to the indi- vidual dairy for his personal requirements. Therefore, the milk problem necessarily evolves itself into a commercial basis; for without the commercial incentive the consumer can not receive any milk unless he produces it himself. There can be no obligation compelling the existence of dairymen, their pro- duction of milk at a cost not commensurate with their selling price, or the distribution of it not contingent on a revenue basis. We have made a special study of the tuberculin test, its advantages and disadvantages, in connection with the litigation which has been forced upon us by the requirements of the town of Montclair, of New Jersey, which case has been in litigation for some time, and in which we have endeavored to procure the testimony of the most learned, unbiased experts upon all the questions involved of bovine tuberculosis, tuberculin test, and the trans- missibility of bovine tuberculosis to human beings ; all of these subjects having been exhaustively examined and testified to in connection with that case. Very truly, yours, ■ Borden's Condensed Milk Co., F. J. Taylok, President. Hearings on the Milk Subject Before the Committee of Chamber of Commerce. Mr. Chairman and Gentlemen of the Committee: You have asked me to appear before you and state my views as to the best methods of procuring a safe and clean supply of milk for the District of Columbia. It must be con- ceded by all fair-minded and self-respecting men that the District of Columbia is entitled to and should have a good, fresh, pure, supply of milk at reasonable prices. As to just what constitutes the required or ideal supply of milk seems to be the subject for discussion to-day. After 40 years' experience in the business myself, and aided by the experience of the very best medical thought to-day, I feel safe in saying that the one and only safe milk for the people of the District to use is pure, clean, cow's milk in its raw state. To adopt either of the substitutes that are now before the commissioners, namely, the com- pulsory tuberculin testing of cattle or compulsory pasteurization, would result in an expensive and serious failure. If you will permit me I will give you a short history of tuberculin and what it has done since discovered. About 1882 Prof. Koch discovered what he claimed to be a diagnostic for the tubercle bacilli and published the same to the world. He was pounced upon by the medical profession and the pathologists, not only in the Old World but in America. So hard was he pressed for proof of his discovery that he asked the medical world to suspend judgment and give him sufficient time to make further research, and if possiblfe substantiate what he said or back down from the position he had taken. For several years (I do not know the exact time) the matter was allowed to lay dormant and was not heard from again until about 1890, if I remember correctly, when Prof. Koch came before the medical world like an honest man and declared to the medical profession that he " had made a mistake in the assertions he had made before, and that his tuberculin was not a reliable diagnostic." He steadfastly stood by that assertion (until his death a few months ago), notwithstanding the pressure from the medical men in both European countries and America. Prof. Bangs, of Copenhagen, has had more to do with tuberculin than any other man that I know of, and after using it for many years declared that tuberculin was " not a true diagnostic and could not be relied upon at all times." About 18 years ago, as well as I remember, the tuberculin testing of cattle was taken up in the United States. Most of the New England States at different times have tried it, and while there may be some laws on the statute books yet which require it. so far as I can learn none of them enforce it. Pennsylvania was next to take it up after the New England States, and after slaughtering many herds decided it was not practical. Only a few years ago the great dairy State of New York passed a law and made an effort to enforce it, but soon abandoned it. Since that time many of the Western States have taken it up, but so far as I know now there is not one State in the Union that enforces it, and it was only a few weeks ago that the Supreme Court of the great dairy State of Iowa decided that the law was unconstitutional. THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 245 PEOBABLE RESULTS IF THE TUBEKCTJLIN TEST IS MADE COMPULSORY, Assuming that the figures given out by the dairy division of the Agricultural Department are correct, and I haven't any reason to doubt them, the per cent of reacting cattle in the District was about IS per cent. Basing our estimate on these figures we must look for something like 16 or 18 per cent of reacting cattle in the States of Maryland and Virginia, and it is only reasonable to assume that something like 10 per cent of the farmers will be forced out of the business or will abandon it sooner than submit to the test. Conceding this to be true we must look for something like 25 or 30 per cent decrease in the herds in the States of Maryland and Virginia. If this supposition is borne out we must naturally expect something like 25 per cent shrinkage in the supply of milk. With the present shortage of milk added to what we may look for if com- pulsory tuberculin testing is insisted on, it will surely drive ofC all competition, and when competition is destroyed it must be apparent to anyone that an unreasonably high price will obtain. Nor is this the only bad result. Should the price of milk be forced up to something like 10 or 12 cents a quart it will surely put it beyond the reach of from 40,000 to 60,000 people in the Dis- trict, and a large portion of this class must necessarily be young children, who will never have an opportunity to indulge in a glass of milk. If the commissioners and the Agricultural Department deem this action wise and philanthropic they should proceed on lines that will insure milk from tuberculin tested cattle. But before doing this it might be well to consider, first, whether they are justified in taking this milk from the mouths of these people without offering them any substitute that is as cheap and as good as the milk they now have ; second, whether they are getting any better milk than they would at 8 or 9 cents a quart, since no one can dare come forward and say that they have proof positive that tuberculosis can be transmitted from the bovine to the human family and since no one can bring proof positive that even one case can be shown to have been introduced into the human family by milk. Nor is this all. The preponderance of evidence to-day with those who have had experience with the tuberculin test declare it is not an infallible diagnostic, and will not cause a reaction after cattle have been tested with it three or four times, and opens the way for more duplicity and rascality than any other test I know of. COMPULSORY PASTEURIZATION. There is very little that can be said in favor of pasteurized milk, and from my viewpoint there is only one condition under which milk should ever be allowed to be pasteurized, and that is in the home under the instructions and advice of a practicing physician. To permit the pasteurization of milk under any other conditions is dangerous in the extreme and should not have the sanction of any conscientious gentlemen. The use of pasteurized milk in foundling asylums, children's hospitals, and similar institutions has long since been abandoned and is now regarded by most all physicians of note as an unsafe diet and should not be tolerated. To temporize with either of the above expedients will only defer for 5 or 10 years the accomplishing of what we might call an ideal dairy supply for the District of Columbia, and might in the end defeat the very object for which the authorities are work- ing. To destroy competition is detrimental to the consumer, and anything that tends to decrease the supply must necessarily aid in the destruction of com- petition. It should be the object of the authorities to make the laws covering the milk traffic sufficiently broad to protect the dairy producers in their property rights and at the same time stringent enough to safeguard the public and induce capital to invest in the dairy business, instead of making short-sighted, vexatious, and drastic regulations that will drive the business in the hands of unscrupulous men, as it is a well-known fact that it is next to impossible to properly police the milk business. Respectfully submitted. C. Thompson. 246 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. Sheffield Farms-Slawson Decker Co., New York, October 21, 1910. Mr. J. L. WiLLiGE, Chairman Chamber of Commerce Milk Committee, Washington, D. C. Dear Sir : I have been following the crusade that the authorities in Wash- ington are making for the betterment of the milk supply of that city and their endeavors to make the pasteurization of all milk that does no come from tuber- culin-tested herds compulsory. I notice in this morning's issues of the ISew York Times and New York Herald that the Milk Dealers' Association have brought in, as a defense, that if pasteurization is required that it would place the dealers in the hands of a trust, who are reaching out to control the entire milk supply of the country. The only dairy products organization that I know of, members of which were named in the issue, is the American Farm Products Co., a concern that has confined its efforts to the renovating of butter, and which, if my memory does not fail me, has gone in the hands of a receiver. I trust that the crusade the authorities are making will be successful, as it is the logical ultimate outcome for a pure-milk supply all over the world. The pasteurization of milk recommends itself from every standpoint, It is cheaper to pasteurize and bottle milk in the city in large plants than it is to bottle the milk in the country without pasteurization. Pasteurizing machinery is very cheap, and can be obtained from half a dozen or more concerns, and where the work can be done properly under official supervision, as is possible in the city, the public gets all the benefit and no increase in the retail price is necessary. Yours, very sincerely, D. S. Hoeton, Secretary. Nathan Straus Pasteurized Milk Laboratories, Washington, D. C, October 28, 1910. Mr. J. Louis WiLLIGE, Chamber of Commerce, Washington, D. C. My Dear Sir : In connection with the investigation now being carried on of the milk situation, I beg to invite you and your committee to visit the Nathan Straus Laboratory here in Washington. We are endeavoring to carry out the most approved methods in the care and pasteurization of milk, principally of modified milk for infants, and I feel it would doubtless be of assistance to you to see our plant In operation. The milk is received before 8.30 in tbe morning and is immediately modified and pasteurized, being ready for distribution by 11. If you could come to see us while we are at work, we should be very glad to have you. However, we are open daily until 5, and I would be glad at any time to explain our methods to yourself and committee. Trusting I may have the pleasure of seeing you here, I am. Yours, very respectfully, (Miss) Reba J. HuEN. Nathan Straus Pasteurized Milk Laboratories, Washington, D. C, November 17, 1910. Mr. J. Louis Willige, Chairman Chamber of Commerce Committee, 603 Thirteenth Street NW., City. My Dear Mr. Willige: I beg to inclose herewith the list questions sent me by your committee, answered as best I can. Many of the questions can be answered only by scientists, whom I have followed in my answers and whom you fortunately have been able to interview personally. May I remind your committee of the invitation to visit this laboratory and see both how we handle the milk and also the philanthropic side of our work in caring for the poor babies? I trust you may find it possible to come at some early date. Yours, very respectfully, Beba J. Hubn. 1 THE MILK SITUATIOK IN THE DISTEICT OF COLUMBIA. 247 I ' BuRNSiDE (Post Office Eccleston), Md., Beccniher 6, 1910. J. L. WiLLiGE, Esq., Chairman, Washington, D. G. Deae Sir: Your letter to the Walker-Gordon Laboratory of Washington has been referred to me, and I herewith inclose the question sheets answered so far as I feel competent. I am also inclosing pamphlet, issued some little time ago, descriptive of the farm where Burnside milk is produced. Here all employees report any sick- ness in their families. Our medical adviser is at once consulted, and until he decides that the disease is not contagious that employee takes no further part in the handling of the milk. 1 consider this second only to integrity in the safeguarding of milk. The purpose of the Walker-Gordon Laboratories is to fill the prescriptions of physicians for milk containing definite percentages of fat, protein, sugar, etc., and to furnish such other food for infants as the physician may prescribe. While the laboratories sell a high grade of milk and creams for nursery and table use, and a number of milk preparations, such as buttermilk, kephir, koumiss, etc., they offer nothing that could properly be classed with propri- etary foods. No modified or prescription milk is sold except on the order of a physician, who rarely has difficulty in so changing his prescription as to make the milk entirely suited to the digestion of the patient. The modifiers, or prescription clerks, use carefully prepared tables by which many thou- sands of different combinations can be effected without any chemical change in the milk constituents. Where the child is doing well at the breast, but the mother has not sufficient milk, the physician may have the mother's milk analyzed, and, as nearly as is possible in cow's milk, reproduced for additional feedings. I have endeavored to give you some idea of our aims, but it would be far more satisfactory if I might have the pleasure of showing you and the other members of your committee our plant, and I should be glad to know that it would be agreeable to you to visit us. So far as I know now I shall be free to meet you here any day you may select except the 9th, 10th, and 15th instant, and hope you will name an early date. Yours, sincerely, S. M. Shoemakeb. New York White Cross Milk Co., New York City, NovemI)er 30, 1910. Chairman of Milk Committee, Chamber of Commerce, Washington, D. C. Dear Sir : I am herewith returning you the list of questions asked by your special committee. You will note that there are many questions I have made no attempt to answer, but if it is of ^interest to you, I will write you on pasteurized milk, condensed milk, and concentrated milk, in comparison with raw milk. I will treat the condensed milk and concentrated milk without the addition of sugar as a preservative in either case. Condensed milk is a product of milk, not milk. It is really milk from which a portion of the water has been removed and is carried a few degrees higher in temperature than pasteurized milk (190 to 200°) for the purpose of coagu- lating and albumin and casein, but this condensed milk has the same vital objec- tion to be used as a general milk that follows with pasteurized milk, while when freshly made, it would show a very low bacteria count and the absence of pathogenic germs, but as it spoils it developes a putrefaction, and hence is liable to produce a toxic condition. It is well understood that in milk subjected to a vacuum there is a breaking down of cells and is followed by a sensible decomposition of the proteids. Pasteurized milk is a milk that is subjected to a temperature varying from 140 to 165° ; different temperature depending on the length of time of the exposure of milk to this temperature. It is much safer when freshly pasteur- ized than it is as it grows older, as it is a well-recognized fact that in the city of New York pasteurized milk is not permitted to be sold by a dealer after it is 24 hours old, and while the bacteria count might be low, it is liable to decomposition, and as often decomposition has no taste the very warning that is necessary for spoiled milk is not there in the shape of souring and the conditions are right for a toxic poison. If the temperature has been carried 248 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. high enough, there will be a change in the albumin and caseiu, and certainly a destruction in the enzymes. There are three conditions that render the pasteurization of milk impractical from a commercial standpoint, if a perfect milk is to be served : First. If the milk is pasteurized at the creamery, and their lack of proper skill and integrity makes it impractical. Second. If the milk is pasteurized in the city, the increase in the number of bacteria from the farmer to the city increases the number of bacteria, and consequently the milk is more liable to the putrefaction, above referred to. Third. There is no positive way of knowing or no physical change in the milk that absolutely guarantees that the product has been so treated, and can only be determined after a day or two when the milk is all consumed and the harm done, and in this case, the digestibility of the milk is impaired and is not as safe as pasteurized milk. To my mind the great quantity of milk consumed by large cities can never be properly guaranteed as clean, pure milk unless there is a physical change in the milk, and this miist be brought about at the creamery ; such change not to affect the component parts of the milk ; to have no effect on the enzymes, and when the product becomes old it should develop a lactic ferment. Concentrated milk is a milk from vvhich three-fourths of the water has been removed. This is the object at the creamery, and the removal of B. coli and all pathogenic ferms are mere incidents ; the force at the creamery have but one object in view — the removal of the water and the reducing of the product to a certain specific gravity. Concentrated milk when it becomes old invariably produces a lactic ferment. The fat globules are the same in concentrated milk as in the normal milk. The enzymes are unchanged and the digestibility is not impaired, and in no instance in the many tests has there been any sign of a putrefaction as the product becomes old. Trusting I have furnished you some information that will be of value, and if you would like to have any data confirming what I have just written I will be pleased to send it, as we have reports from scientists of recognized ability. Yours, very truly, C. H. CampbelIi. The Creameby Package Manufactueing Co., Chicago, III., November 11, 1910. The Washington Chamber of Commerce, 1202 F Street NW., Washington, D. C. Gentlemen : Your favor of the 5th instant, with list of questions, received and very carefully noted. We attach hereto this list with our answers. We have given you the very best information we are able in this connection with- out prejudice from the standpoint of being interested in the manufacture and sale of pasteurizing machines. We are in pretty close touch with this situation throughout the country and believe that our advices can be considered of a conservative character. Very truly, yours, Creamery Package Manufacturing Co., H. B. Osgood, Sales Manager. INFORMATION DESIRED BY SPECIAL COMMITTEE APPOINTED BY THE WASHINGTON CHAMBER OF COMMERCE TO INVESTIGATE THE MILK SITUATION OF THE DISTRICT OF COLUMBIA. 1. Please state the advantages of pasteurization. Destruction of lactic-acid bacteria, insuring keeping qualities ; also destruc- tion of disease germs, protecting health. 2. What valid objections have been presented in opposition to pasteurization? No valid objections to proper pasteurization have ever been presented. It is claimed by some who are opposed to pasteurization that it acts as a cloak for all sorts of improper care and handling of milk. We believe, however, you are considering this from the standpoint of milk handled under modern sanitary conditions and pasteurized in accordance with the most approved methods. 3. What is the cost of pasteurizing milk per pound or per gallon? About one-eighth cent per quart. The cost is dependent to a large extent upon the amount of milk handled and the cost of fuel, etc. THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 249 4. Should this cost, in your judgment, properly add to the retail price of milk? No. The saving in other directions offsets it in the increased volume of business, and the practical elimination of losses from sour milk more than makes up for the cost of pasteurization. 5. What is the cost of an efficient pasteurizing machine with its accessories and of what capacity? With a capacity of 4,000 pounds per hour, about $2,500. 6. What is the estimated cost of a pasteurizing plant completely installed? With a capacity of 4,000 pounds per hour, $5,000 and up, depending upon whether this question is intended to cover equipment for bottling, refrigerating machinery, etc. 7. Is compulsory pasteurization, in your judgment, feasible and advisable? Yes. There is no reason at the present time why the city milk plants, from largest to smallest, can not be equipped with proper pasteurizing machinery at a cost within their means if they have sufficient capital to properly handle their business. 8. Would you recommend the establishment of a municipal pasteurizing plant (or plants) if compulsory pasteurization be insisted upon, so far as concerns milk and milk products consumed in the District of Columbia? No ; we do not believe that a proposition of this sort can be successfully and economically handled by municipal government. 9. At what temperature and for what length of time should the milk be heated in the pasteurizing process to produce the best results? One hundred and forty-five degrees Fahrenheit for 30 minutes. 10. Is pasteurized milk, in your judgment, more or less easily digested than raw milk? If properly pasteurized at 145° F., there would be no difference whatever. 11. What advantages has pasteurized milk compared with modified condensed and powdered milk? Pasteurized milk and other kinds of milk mentioned are so different in char- acter that there is no basis of comparison. 12. Does pasteurization tend to preserve milk? Certainly, as the lactic acid germs are destroyed. 13. Is it necessary to preserve the same precautions with pasteurized as with raw milk? Certainly. 14. Are there a number of efficient makes of pasteurizing machines? Only three that have undertaken to embody the latest principles of pasteur- izing and holding. 15. Is there, so far as you know, a monopoly controlling the production or sale of pasteurizing machinery? No. Manufacturers of these machines are all independent of each other and in keen competition. 16. In your judgment would compulsory pasteurization dispense with the necessity or feasibility of applying the tuberculin test? A reply to this question we think would depend entirely upon the final con- clusions of scientific authorities as to the efficiency of the tuberculin test. It is our understanding at the present time there is a very wide difference of opinion on this point. So long as there is any question as to the efficiency of the tuberculin test in our judgment all milk should be pasteurized. 17. What maximum temperature should be prescribed for the preservation of pasteurized milk? From 35 to 40° F. Derby, Conn., November 15, 1910. Chamber of Commerce, Washington, D. G. Gentlemen : We have your favor of November 5 asking us to answer ques- tions with regard to pasteurization. The writer does not care to give you any information for the simple reason that there are quite a number of questions that we feel should not be answered by us. For instance, your question 1 : " State the advantages of pasteurization." Although we are expert engineers on milk, we leave it up to the medical au- thorities to decide if pasteurization is an advantage, but- as far as we know 250 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. this has been settled by the Department of Agriculture. The Dairy Division recommends that all commercial milk should be pasteurized for 30 minutes at 145°. As this is an invention of the writer, all he can say is that he is proud that the Government recommends his work. 2. This question has to be answered by physicians. All I can say is that 99 per cent of all physicians do not know the first thing about milk, and there- fore I am not in a position to criticize either raw milk or pasteurized milk. 3. The cost of pasteurization of milk depends entirely on the quantity of milk that is handled and on the process used. We naturally are steadily working along the lines of reducing the cost of operation, and on the very latest machines which we are building the cost for steam and refrigeration is only a small percentage of what it has been up to the present. The cost of pasteurizing, therefore, of 1 quart of milk is only a very small fraction of a cent in lai'ge plants. 4. This is a question to be decided by the man who sells milk. 5. Our perfect pasteurizers, 12,000 pounds capacity per hour, cost $5,000 per machine. However, it is necessary to have refrigerating plants in connection with this machine, and therefore the price will naturally be a great deal higher. 6. Pasteurizing plant installed, with refrigerating machine necessary to take care of the milk, varies according to its size. We build plants from 3,000 pounds per hour up to 12,000 pounds per hour. We have one at Mr. Oyster's plant in Washington, D. C, of about 6,000 pounds per hour, and a plant of that size, including refrigerating machine and boiler, is worth between $15,000 and $18,000. For a 12,000-pound plant the cost of the pasteurizing outfit, with refrigerating machine, etc., would amount to between $25,000 and $30,000. 7. The only way to protect the public against all kinds of infection from the filth that is found in all milk, except in certified milk, is to pasteurize it. It is a shame that in cities like New York and Boston there were epidemics of considerable extents this last week, due to infection through raw milk. In New York there was a typhoid-fever epidemic of over 400 cases, and in Boston the scarlet-fever epidemic had over 800 cases. When it comes down to deter- mine if it is better for a city to have such epidemics or to heat such milk, then, in my judgment, there is only one answer, and that is to pasteurize the milk. For myself, as a specialist on milk, I would not dare to feed my own children on raw milk even if it is certified, and I am happy to say that I have brought up children as strong as anybody can have, and all they ever got was boiled milk. 8. We believe that in the United States it is better to have individual pasteur- izing plants — that is, handled by individual concerns. The milk business, as a rule, is to-day in the hands of a great many ignorant people, and there are only a very small percentage of men handling these prod- ucts who have any brains at all. Therefore the few that have intelligence should be separated by the communities in which they live, and the others have no right to be in business and sell their low-class products. I am personally afraid that if pasteurizing plants would be run by cities it would not be satisfactory. If they would be in charge of a high-class chemist or engineer it would be a different proposition. 9. Our Mr. Willmann is the inventor of the pasteurizing process of heating milk continuously for 30 minutes at between 145 to 150° F. We have men- tioned above that the Government is recommending this process; therefore we have nothing else to add. 10. From my experience with my own children I never found that raw milk agrees better with them than pasteurized milk.' 11. Pasteurized milk has the same taste, like good raw milk, while condensed milk has been subjected to such high temperatures that it always has a cooked taste. Further, the pasteurized product is sold fresh, while condensed milk is sometimes very old before it is consumed. It is always better to get an article as fresh as possible, because there may be some chemical changes that may take place with the age, although we have no scientific proof that such is the case. Some of the milk powders are made from high temperatures, and in nearly all of them the casein has been denaturalized, and therefore is not as easy to digest as casein in pasteurized milk. The sugar, salts, and fats, and powders are naturally not changed. 12. Pasteurization preserves milk for a certain length of time, and if it is properly cared for it will keep a few weeks. The hospitals of the Panama THE MILK SITUATION IIST THE DISTRICT OP COLUMBIA. 251 Canal are supplied with perfectly pasteurized milk that runs through one of my machines at the Sheffield Farms-Slawson Decker Co., of New York City, and this will give you evidence enough that such pasteurized milk naturally has to keep, because without this it could not be shipped from New York to Panama and arrive there in perfect condition. 13. Pasteurized milk should be handled at least just as carefully as very high-class raw milk. The average raw milk is handled by farmers, and their hands are naturally dirty, and therefore raw milk is naturally dirty. Milk should not only be pasteurized, but it should also be subjected to very thorough filtration, so that the dirt, which is chiefly cow manure, can be removed from the milk beforehand. Pasteurization should not mean treatment of dirt but treatment of reason- ably good raw milk, which can be rendered safe by that process. It is impos- sible for the next generation to change the farmers, and it will be impossible to change them for generations to come ; therefore pasteurization will be the only process that will give us a safeguard against infections that are conceived through raw milk. 14. This is a question that has to be answered by the authorities. We build our machines and do not want to criticize any other make. The process of perfect pasteurization is our patent, but every housewife can heat the milk for the same length of time and at the same temperatures with- out infringing on our process; therefore we can say that apart from the large machinery that works automatically on the holding process, pasteurization is public property. 15. There is absolutely no monopoly controlled by the sale or ,a production of pasteurizing machinery. All we know is that the different manufacturers fight each other in the worst way for trade. 16. In my own judgment the tuberculin test should be applied gradually to the various herds. Pasteurization will have to be used anyway, because scarlet fever, typhoid fever, etc., are much more important from a milk stand- point than tuberculosis. Every farmer should pasteurize all the milk that he feeds to his stock, so that he does not infect the young animals with tuber- culosis. Under the present conditions it is absolutely impossible to have all the herds tested, because there are not veterinarians enough to do the testing in 25 years. 17. Pasteurized milk should be kept at temperatures of 50° F. Such a regula- tion would be in the interest of the milk dealer as well as of the consumer, because it will protect both. If you need any more detailed information about the subject, I will be very glad to take this matter up with you. Very truly, yours, Dairy Machinery & Construction Co. J. WiLLMANN, President. APPENDIX D. CORRESPONDENCE WITH TRANSPORTATION COMPANIES CONCERNING REFRIGERATOR-CAR SERVICE FOR TRANSPORTATION OF MILK. November 5, 1910. President of the Pennsylvania Railway Co., Philadelphia, Pa. Dear Sir: The special committee appointed by the Washington Chamber of Commerce to investigate the present milk situation in the District of Columbia is desirous of obtaining, if practicable, information as to the feasibility of supplying refrigerator cars for the transportation over your lines from pro- ducers shipping to the Washington market, together with a statement of the cost of refrigeration of each car per day or per trip, and the cost of shipment per pound or per gallon of milk from varying distances to Washington. 252 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. Any information along these lines which you may be able to supply for the edification of the committee will be greatly appreciated. Very respectfully, yours, J. Louis Willige, Chairman. P. S. — Kindly indicate additionally how much ice per day or per trip Is required to refrigerate a car for the transportation of milk at a maximum temperature of 50° F. Note. — Letters similar to the above were sent to the presidents of the Balti- more & Ohio Railroad Co., the Chesapeake & Ohio Railway Co., the Southern Railway Co., the Atlantic Coast Line, and the Seaboard Air Line. The Pennsylvania Railroad Co., Philadelphia, Novemher 8, 1910. The Washington Chamber of Commerce, Washington, D. C. Dear Sirs : I beg to acknowledge the receipt of a letter from the cha irman of a special committee of the Washington Chamber of Commerce, requesting certain information in connection with the transportation of milk in refriger- ator cars over our lines to the Washington market from points in that vicinity, and I have referred it to the third vice president, in charge of traffic, with the request that prompt reply be made thereto. Yours, truly, James McCrea, President. The Pennsylvania Railroad Co., Philadelphia, Novemlter 21, 1910. Chairman Washington Chamber of Commerce, 1202 F Street NW., Washington, D. C. Dear Sir: Your favor of the 5th instant, addressed to the president of the Pennsylvania Railroad Co., having reference to the feasibility of supplying refrigerator cars for the transportation of milk over our lines from producers shipping to the Washington market, together with a statement of the cost of refrigeration of each car per day or per trip, etc., has been referred to this department for reply. More prompt answer would have been given, but it has been found necessary to refer these questions to the superintendent of passenger transportation and the general superintendent of motive power, and the careful consideration which those officials have found it necessary to make in connection therewith has delayed replies. ■ It is very difficult to answer a general question of this kind; that is, as to the cost of refrigeration per car per day or per trip, and how much ice per day or per trip is required for a refrigerator car for the transportation of milk at a maximum temperature of 50° F., as there are so many conditions surrounding a general proposition of that kind that would have a material bearing on this question. There are three factors that would enter into the hauling of milk under re- frigeration, namely, length of the haul, temperature of the milk when placed in the car, and whether the cars would be loaded all at one point or at intervals between originating point and destination. If a class " Rf " refrigerator car was used for this purpose, the initial icing would require 7,400 pounds. After precooling, 4,000 pounds would be suffi- cient to carry the milk under a temperature of 50° F. for a distance of 300 miles, or a 24-hour run. However, if the car were to be opened at different points to receive milk, the temperature would fluctuate according to outside conditions. The cost for icing a car with 12,000 pounds of ice would approximately be $15; this on the basis of ice at $2.50 per ton, including the necessary labor. By keeping the same cars in this milk service the bunkers would retain a per- centage of ice from one trip until the next, and thus would require an average of only about 3,000 pounds of ice, at a cost of $4, on the same basis as above. The cost per gallon for refrigerated milk would depend on the number of gallon cans that would be loaded in a car. THE MILK SITUATIOISr IN THE DISTRICT OF COLUMBIA. 253 The length of the haul would make no material difference in the refrigera- tion cost, due to the fact that the requisite amount of ice and the necessary space for lading would have to be provided from the starting point of the car to place of receiving and discharging the lading. The present cost of shipment per gallon of milk from varying distances to Washington is: For distance of less than 30 miles, li cents per gallon. For distance of 30 miles and not exceeding 60, 2 cents per gallon. For distance of over 60 miles and not exceeding 90, 2| cents per gallon. These are the rates for milk, and double said rates are charged for cream. Yours, truly, J. R. Wood, Passenger Traffic Manager. SoxjTHEEN Railway Co., Washington, D. C, 'November 9, 1910. Mr. J. Louis Willige, Chairman Milk Committee, Washington Chamber of Commerce, Washington, D. C. Dear Sir : I have your letter of the 5th instant requesting information as to the feasibility of supplying refrigerator cars for the transportation of milk into Washington. I have brought your communication to the attention of Vice President Gulp, who is in general charge of trafhc matters, and have asked him to write you direct on the subject. Yours, truly, W. W. Finley, President. Southern Railway Co., Washington, D. C, 'Novem'ber 16, 1910. Mr. J. Louis Willige, Chairman Millc Committee, Washington Chamber of Commerce, Wa,sMngton, D. C. Dear Sir : Please see your letter of November 5 to Mr. Finley requesting information as to the feasibility of supplying refrigerator cars for the trans- portation of milk from points on the rails of this company to Washington. We have never given consideration to a proposition of this character ; there- fore it is a matter that we will have to determine, and before we can reach a con- clusion it will be necessary to have complete information. I assume your com- mittee fully understands that the handling of milk in refrigerator cars means transportation by freight service, whereas the milk is at present being handled by passenger trains. Refrigerator cars, if put into service, would, of course, stop at practically all local stations within a certain radius of Washington ; therefore they would have to be handled on our local freight trains, which, as now adjusted, would, no doubt, be entirely impracticable in so far as the schedule is concerned. This entire matter can doubtless be handled in conference much more satis- factorily than by correspondence, and I suggest, if practicable, that you call at the office of our freight traffic manager, Mr. Green, or if you prefer, we can have a representative call upon you for the purpose of fully discussing this matter. Yours, truly, J. M. Culp, Vice President. November 5, 1910. The President New Yokk Central & Hudson River Railway. New York City, N. Y. Sir : I am requested by the special committee of the Washington Chamber of Commerce appointed to investigate the present milk situation in the District of Columbia to ask that if practicable you will be so good as to arange for the enlightenment of the committee a statement as to the cost per day, or per trip, of car refrigeration for the shipment of milk and the cost per pound or gallon of milk when transported in refrigeration cars for varying distances. 254 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. The committee is endeavoring to decide whether it is feasible to recommend a compulsory maintenance of a maximum temperature of 50° F. in the shipment of milli from the producer to the consumer in the District of Columbia. Assuring you in advance that any information vphich you may be able to furnish along the line indicated will be deeply appreciated by the committee, I am, Very respectfully, yours, J. Louis Willige, Chairman. New York Centbal Lines, New York, November I4, 1910. Mr. J. Louis Willige, Chairman the Washington Chamber of Commerce, Washington, D. C. Dear Sir : Replying to your letter of November 5, in regard to the cost of refrigeration of milk, butter etc. : I regret to say that it will be impossible for me to give you any definite figures to base your arguments upon, for the reason that the cost of refrigeration varies on different parts of our line. It is governed by weather conditions, the kind of container in which the product is shipped, length of haul, facilities and rapidity of unloading at destination, etc. While an average cost might be prepared, yet it would be of no value for the purpose you desire, as conditions in the District of Columbia are different from those in New York State. As I understand it, 50° is the maximum permitted in our refrigeration, as above that temperature bacteriological conditions are said to be undesirable. There is, on the other hand, a minimum below which it is unnecessary to go, and, all things considered, to obtain the best results, the temperature of the car should be somewhere between 45° and 50°. Trusting that this information will be of service to you, I am. Very truly, yours, W. C. Brown. APPENDIX E. COMMUNICATION ADDRESSED TO PRESIDENT OF MILK PRODUCERS' ASSOCIA- TION or MARYLAND, VIRGINIA, AND DISTRICT OF COLUMBIA. November 26, 1910. Mr. John Thomas, President Milk Producers' Association of Maryland, Virginia, and District of Columbia, Ednor, Md. Dear Sir : The special committee appointed by the Washington Chamber of Commerce to investigate the present milk situation begs to aclvnowledge the receipt of your valued replies to the series of inquiries forwarded you several weeks ago. In so far as information has not already been supplied by the milk producers' association, the committee will be pleased to receive, if possible, an expression of the sense of the association on the following points: 1. Is the dairy farmer supplying milk to the District of Columbia receiving, in the judgment of the association, his proper shai-e of the proceeds of sale of milk and milk products? 2. Is an uniform standard the year round of prices received by the producer for milk supplied to the District feasible? 3. If compulsory pasteurization, the general application of the tuberculin test, and the maintenance of temperature below 50° F. be insisted upon, what would be the effect, in the judgment of the association, on the prices asked for milk by the producer? Your kind cooperation with the committee in providing intelligent information on the above points will be deeply appreciated. Respectfully, yours, J. Louis Willige, Chairman.

Rule 49. Condition and care of cows for production of milk. — The cows must be healthy and free from tuberculosis. If an examination by the dairy inspector shows evidence of excessive emaciation, glandular enlargement, nodular forma- tions, mastitis, tumor, recent parturition, cough, dyspnoea, fever, pneumonia, exhaustion, lockjaw, blackleg, anthrax hemorrhagic septicemia, or any other infectious disease, or any evidence of tuberculosis, the milk of the herd shall be declared infected until the unhealthy cow or cows have been removed and until an acceptable statement from a recognized, licensed veterinarian or regular dairy inspector is filed with the milk division showing that such suspicious cow or cows are free from infectious disease. Milk from cows reacting to tuberculin shall be rejected unless it shall have first been pasteurized at a temperature of 175° F. or over for 30 seconds or longer in a stream not more than a quarter of an inch thick. Milk from cows 15 days before and 1 week after calving shall be rejected. Cows must be kept as clean as possible on flanks, belly, udder, and tail. I^ong hair must be clipped from the udder and sufficiently from the tail to clear the ground. The feeding of slops, refuse of any distillery or brew- ery, glucose, or any malt and ensilage that has been subject to fermentation, putrefaction, or decomposition is prohibited. Pure water in sufficient quantities must be at hand at all times. The cows must not be overheated by hard driv- ing, nor be allowed to stand in mudholes, dirty sloughs, or ditches. Mudholes, dirty sloughs, and ditches shall not be allowed to exist in the pastures or cow yards where cows for the production of milk are kept. Rule 50. Condition of darnyard for production of clean milk. — The barnyard or cow yard must be kept reasonably clean and free from mud, soft manure, and must be well drained. Piles and heaps of manure shall not be less than 25 feet away from any stable door or window between December 1 and April 1 and not less than 300 feet avi^ay during the other months of the year. Rule 51. Stable for production of clean milk.— The floors must be tight, pref- erably constructed of cement, and free from defects. The ceilings should be tight if a storage loft is kept above. The walls should be whitewashed every spring and fall and kept clean at all times. Each cow must have at least 400 cubic feet of air space, and there must be ample provision for movement of air and ventilation, so that the air never gets foul. At least 2 square feet of unob- structed window-glass space shall be provided for each cow. Soiled bedding must be removed daily and the manure must be removed from the stalls and open manure gutters twice a day. All bedding, removing of manure, sweep- ing, and cleaning of mangers must be done at least one-half hour before milking. The stable must be reasonably free from flies. Cats and dogs must not be per- mited in the stable. Rule 52. Milkers in relation to production of clean milk. — Milkers should neither have nor come in contact with contagious disease. Should any case of communicable disease — such as scarlet fever, smallpox, typhoid fever, diphtheria, measles, or chicken pox — occur on the dairy farm among the milkers or their families, the division of milk inspection must be promptly notified. The contagious diseases of importance in relation to milk are: CONSUMPTION. Milkers and attendants in the cow stable and milk room should be free from tuberculosis. A consumptive can be harmless if he is intelligent and can be trusted to carry out the physician's instructions, viz, to receive all the sputum in a sputum cup or on clean cloths and properly destroy it by fire or immersing in 1 to 5,000 bichloride or 5 per cent carbolic-acid solution. Consumptives should never be allowed to cough without using a clean cloth before their mouth, and under no circumstances be permitted to moisten their hands with saliva before milking. They siiould always wash their hands well before beginning to milk and after each handling of sputum cloths. If the indi- vidual can not be relied upon to do this at all times he should be excluded from the dairy and given employment out of doors. If consumption occurs in the milker's family or in the family of the farmer where the milker is rooming or boarding, the same instructions in regard to the care and disposition of the sputum should be issued. In case of death, the house should be thoroughly disinfected bj^ using 8 ounces of formaline to 1,000 cubic feet, spread upon sheets left in the rooms for 8 hours, with the windows and doors tightly closed. THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 273 The milkers affected with or convalescent from this disease should be abso- lutely excluded from the dairy. On account of the infectiousness of the excreta from such individuals, it might be good practice to keep them away from the handling of milk for at least four to six weeks after convalescence. When typhoid fever occurs in the families of milkers or attendants, the greatest care should be exercised in the disposition of the excreta and handling of the bed linen and other clothes coming in contact with the patient. The bowel movements and urine should be disinfected with 4 per cent chloride of lime or 5 per cent carbolic-acid solution and buried. The bed linen and other clothes should be soaked in 1 to 10,000 bichloride solution or 5 per cent carbolic-acid solution and then thoroughly boiled. Special attention should be given to the exclusion of flies from the sick room and also from the dairy. The other mem- bers of the family should be permitted in the dairy only if intelligent and after having been thoroughly instructed in regard to cleanliness and other details. The milking utensils should not be brought into the house, and should always be washed with cloths and brushes that have not come in contact in any way with things from the typhoid patient. Samples of the water used should be sent to the city laboratory in boiled bottles for examination. SCARLET FEVER. Milkers should neither have nor come in contact with scarlet-fever cases. After scarlet fever the scales on the hands carry the contagion for about four weeks and sometimes longer. Scarlet-fever cases during convalescence should not be permitted to come in contact with the handling of milk in any way until the scaling has been completed and they have been given an antiseptic bath, such as a 1 to 10,000 bichloride of mercury solution and their hands anointed with 5 per cent carbolic salve. When scarlet fever occurs in the families of the farmers, milkers, or other attendants, the house should be quarantined. This means that no member of the household or other person must leave that house and mingle with attendants in the dairy in any manner or form while the quarantine exists. The sale of milk and cream from the quarantined premises is not permitted unless the cows are taken care of, the milking done, and the utensils handled by individuals entirely disassociated with the quarantined family. The quarantine is ter- minated only after a thorough disinfection of the premises and the patient in the manner indicated under " Tuberculosis." DIPHTHERIA. Milkers affected with diphtheria or sore throat should be excluded from the dairy. They should not be permitted to retui'u to the care of cows, milking, and handling of utensils until from 10 to 14 days after an attack of diphtheria. Throat cultures should be made to determine the absence of diphlheria bacilli before the patient is pronounced well. In cases of simple sore throat the patient should be examined by a physician before he is permitted to reenter upon his work. When diphtheria occurs in the families of milkers and dairy attendants, the house should be quarantined until the disease lias been properly terminated by throat cultures and disinfection of the premises. SMALLPOX. When smallpox occurs in milkers, attendants, and their families, a strict quar- antine must be established at once. The members of the families not affected should be vaccinated and the quarantine should be continued for about 20 days. This means that the milk and cream produced on these premises shall not be sold for domestic use if handled by individuals who come in contact with such a smallpox case and are still under quarantine. In such cases the milking must be done, the utensils handled, and the cows taken care of by individuals entirely disassociated with the quarantined family. All milkers and attendants should be vaccinated to prevent such outbreaks. MEASLES. Milkers should neither have nor come in contact with measles cases. Measles cases during convalescence should not be permitted to come in contact with the handling of milk in any way until the scaling has completed and they have 82444''— S. Doc. 863, 61-3 18 274 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. been given an antiseptic bath such as a 1 to 10,000 bichloride of mercury solution and their hands anointed with 5 per cent carbolic salve. When measles occurs in the family of the farmer, the house should be quar- antined and the same precautions taken as for scarlet fever. CHICKEN POX. Milkers should neither have nor come in contact vp^ith chicken-pox cases. Chicken-pox cases during convalescence should not be permitted to come in con- tact vs^ith the handling of milk in any way until the scaling has been completed and they have been given an antiseptic bath, such as a 1 to 10,000 bichloride of mercury solution, and their hands anointed with 5 per cent carbolic salve. When chicken pox occurs in the families of the farmer, milkers, or other attendants, the house should be quarantined and the same precautions taken as for scarlet fever and measles. * Rule 53. Milking im, the production of clean milJc. — Before each milking the udder should be wiped with a clean damp cloth or washed with soap and water if necessary. The hands should be washed before starting to milk and again well dried with a clean towel. The hands and teats should be kept dry during milking. If they become moistened with milk, they should be wiped dry with a clean towel. Suitable clean outer garments, such as overalls and jumpers, should be put on before milking. The milk stool must be clean. Milking should be done regularly, having the periods of as nearly equal length as possible. The first few streams from each teat should be rejected. The first half of the milk given should not be separated from the latter half or strippings and be sold separately. The top of the milk pail should be as small as possible — not larger than 6 or 8 inches — to keep out dirt, and if anything falls into the milk, such as straw or manure, then the milk should be rejected. The milk from each cow should be removed from the stable immediately after it is obtained. Rule 54. MilJc cans and utensils for keeping and shipping of clean milk. — ^All utensils used in the production and shipping of milk, such as cans, covers, bot- tles, dippers, skimmers, measures, strainers, stirrers, etc., must be so constructed that all parts are absolutely free from places where milk can accumulate or soak in, so that it can not be removed by simple washing. The surface coming in contact with milk and cream must be smooth and free from excessive rust. All utensils, including cans, must be kept scrupulously clean, inside and out- side, at all times. They should be cleansed by washing with a brush and soap or washing powder and hot water and thorough rinsing. After this cleansing they should be sterilized with boiling water and then kept inverted in a place free from dust and flies. Strainers, whether metal, gauze, or cotton, must be absolutely clean when used for the straining of milk. Milk cans should be used for no other purpose. Bottle caps must be kept in clean, covered, dry, and dust- proof receptacles. All cans and utensils must be free from defects and rough or uneven surfaces. Rule 55. Care of milk on the dairy farm. — The room where utensils, milk pails, strainers, and the milk are kept should be separated from both the house and the stable and be used only for dairy purposes. It should be kept neat, clean, well ventilated, and free from flies and dust. No odds and ends or other unnecessary things should be stored in the milk room. The milk room must be free from odor. Milk should be strained through a piece of clean linen or cotton, then it should be rapidly cooled to 50° F. within two hours after milking and kept below that temperature until delivery. The evening milk must not be mixed with the morning milk, and old milk must not be mixed with the fresh. The cans must be tightly closed when kept in the cooler and sealed when hauled to the milk platform. During this transportation they must be covered and protected from the he'at. This is best accomplished by carrying in a covered spring wagon. Cans should never be delivered too early to the milk platform. They should be covered with a damp cloth in the warm weather while standing there. Rule 56.

Pasteurising temperatures. — All pasteurized milk, cream, skimmed milk, miak products, and milk and cream used in the production of milk products shall be pasteurized in accordance with the following regulations : (A) Continuous pasteurization. In all continuous pasteurization the milk and cream shall be heated to a temperature which shall be determined and fixed by the department of health for each machine at a point corresponding to the temperature required to kill 99 per cent of the bacteria and all pathogenic bac- teria contained in the raw product. For this determination ordinary raw milk 284 THE MILK SITUATION IN" THE DISTRICT OF COLUMBIA. contaiuing in the ueigliborliood of 3,000,UU0 bacteria slaall be used, and the pas- teurized product sball be collected as it flows from the cooling apparatus. All continuous pasteurizers shall be equipped with a feeding pipe which is so constructed that the pasteurizer can not be fed in excess of its normal working capacity ; that is. in excess of the working capacity of the machine at which 99 per cent of the bacteria are killed when the required amount of heat is applied. All continuous pasteurizers operated outside of the city limits for the produc- tion of pasteurized milk and milk products to be sold in the city of Chicago shall be equipped with an apparatus regulating automatically the supply of steam and heat, so as to correspond with and produce the required temperature of the outflow of the pasteurized product. These automatic thermo regulators shall be accurate and must be approved by the commissioner of health before being installed. A recording apparatus shall be installed upon all continuous pasteurizers operated within the city limits so as to record during operation the temperature of the pasteurized product as it flows from the heater. The thermometer of this recording ap]3aratus must be accurate and kept immersed in the milk in such a way that it is not exposed to escaping steam or other heat except the heated milk. The records made by this recording thermometer must be accurate and made in a chamber which is kept under lock and key in the control of the department of health. The automatic thermo regulating and recording apparatus may be combined into one instrument, and it is recommended that all pasteurizers be equipped with both appliances or combination apparatus. (B) Held pasteurization. Whenever milk is held during pasteurization in such a manner that the process of pasteurizing is not a continuous one, namely, a continuous flow of milk through the heating or heat-retaining chamber, the process shall be designated as " held pasteurization." Such methods of pasteurization and pasteurization appliances or systems installed and used shall be examined and approved by the commissioner of health, or his duly appointed representatives, when all of the following requirements are fulfilled : 1. When the pasteurized product shows that over 99 per cent of the bacteria and all pathogenic bacteria contained in the raw product have been destroyed. 2. When the mechanism of the pasteurizer or pasteurizing system is such that the three important elements, namely, the temperature, time of exposure, and the quantity of milk exposed at one time, can be readily kept under control and observation by the department of health. 3.

Care of Milk in the Home. [Issued by the Board of Health of Detroit, Mich.] DETROIT, MICH. The Board of Health, Detroit, Mich., May 1, 1908. The quality of the milk supply of a city has a great deal to do with the health of the people. Milk is the most valuable single article of diet known to man, and is the only proper food for babies under 1 year of age, when they can not get the nourishment which nature intended for them — their mother's milk. But, while good milk is such an excellent food, bad milk is one of the 304 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. most dangerous foods possible, being responsible for a large part of the bowel troubles of babies and for the death of very many of them. The chief means by which milk is made dangerous are (1) dirty methods of keeping and milk- ing the cows, dirty milkers, and dirty milk vessels; (2) failure to cool the milk promptly and keep it cool until used; and (3) keeping the milk too long before it is used. Bad milk, therefore, so far as danger to health is concerned, is dirty milk or warm, stale milk. The Board of Health of Detroit is doing everything in its power to make the milk supply of this city all that it should be from a sanitary and chemical standpoint, and the dairymen are actively responding to our efforts. Nearly all of the undesirable dealers have been forced out of business. But it is not sufficient that the milk be clean and pure when delivered to you. TJnless the proper care is taken in your own home after the milk is received you will not have good milk in spite of our efforts and the work of the dairymen. It is therefore important that you should carefully follow the instructions given in this circular — ^not just to-day, but every day, the whole year round. In the home, as on the farm and in the city dairy, cleanliness and cold are the two essentials in the securing of wholesome milk. All vessels used for milk should be thoroughly cleansed as soon as empty, using first clean, cold water for rins- ing, and then scalding them with hot water containing a small amount of washing soda or borax. After thorough washing, the vessels should be rinsed with clean water and then well aired and sunned in some place where they will be protected from dust. If your milkman delivers his milk in sealed bottles, see that he does not leave these in a place where they will be exposed to the heat of the sun before being brought into the house. They should be taken in as soon as possible and placed at once in the refrigerator until used. As soon as you have emptied a bottle, wash it out carefully. Do not return to your milkman bottles containing stale milk. Milk quickly absorbs odors from surrounding substances. After using part of the milk, always replace the cap before returning the bottle to the ice box. If you are getting bottled milk, and a case of typhoid fever or other " catch- ing " disease breaks out in your house, you should tell your milkman at once, and he should not take away any milk bottles from your house until after the case has gotten well, as one of these bottles might otherwise be the means of carrying the disease to other houses. We will instruct the milkmen what to do in such cases. If you are getting milk in bulk and not in bottles, it is best to have the milk- man deliver it directly to you or your servant, and you should see that it is put on ice immediately and kept cold. The practice of putting out an uncovered pitcher or other vessel for milk the night before can not be too strongly con- demned. Such a pitcher or vessel, exposed to the dust and dirt of the street, will collect thousands of germs before the milk is put into it. Many of these may be dangerous to life and health, besides which they will certainly cause the milk to sour in a short time and become unfit for use. The purest milk received in such a vessel may become as bad in a few hours as the worst milk from a dirty farm. If you wish to stand out a vessel to receive your milk, provide yourself with several glass preserve jars, which should be used for this purpose only. They should be kept well washed and aired as above described. Get jars with clamp tops. Those with screw tops are hard to keep properly cleansed. Do not use the rubber ring which comes with most jars, as it is diffi(?ult to keep clean and the jar will be sufficiently tight without it. Instead of a preserve jar, a bowl covered by a plate may be used. A pitcher can not be tightly covered on account of the projecting spout. Give your own personal attention to your milk vessels. The milkmen of Detroit state that many persons have the idea that if milk is delivered to them warm, this is proof of its being fresh from the cow and hence better. So far from this being true, only by cooling the milk as soon as it is gotten from the cow is it possible to prevent rapid decomposition of the milk in warm weather. The regulations of the board of health (which have been adopted for your benefit) require that all milk sold in Detroit shall be cooled immediately after milking and kept cooled until delivered to you. While bad milk is the chief cause of bowel troubles among young infants, it is by no means the only cause. Improper feeding is another cause. Never give anything but milk to a child under 1 year unless advised to do so by your family physician. THE MIIiK SITUATION" IN THE DISTRICT OP COLUMBIA. 305 If yoTir baby has any bowel trouble, call in your doctor at once, so that the case may be treated before it has gone too far. Never buy milk for the baby from a grocery store. Store milk has often been kept over from the day before. Such milk is dangerous as a food for babies. Never buy bulk milk from a grocery store. Storekeepers are prohibited by a regulation of the board of health from selling bulk milk, which formerly only too often stood around on the floor gathering sweepings or in -an open pitcher or can in a refrigerator, perhaps without ice, in which meats or vegetables were also kept. By paying careful attention to the above instructions you will do much toward keeping your family well during the summer, and especially the little ones who live on milk. You will also find that your milk will keep longer and taste better. Keep this circular and read it from time to time until thoroughly familiar with its contents. If you change servants, be sure to give instructions to the new ones ia the care of milk in your home. LOS ANGELES, GAL.

Dairy Ruxes. the owner and his helpers. Observe and enforce the utmost cleanliness about the cattle, their attendants, the stable, the dairy, and all utensils. A person suffering from any disease or who has been exposed to a contagious disease must remain away from the cows and the milk. 318 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. ' THE STABLE. Keep dairy cattle In a room or building by themselves. It is preferable to have no cellar below and no storage loft above. Stables should be well ventilated, lighted, and drained; should have tight floors and walls, and be plainly constructed. Never use musty or dirty litter. Allow no strong smelling material in the stable for any length of time. Store the manure under cover outside the cow stable and remove it to a distance as often as practicable. Whitewash the stable once or twice a year; use land plaster in the manure gutters daily. Use no dry, dusty feed just previous to milking ; if fodder is dusty, sprinkle it before it is fed. Clean and thoroughly air the stable before milking. Keep the stable and dairy room in good condition. THE cows. Have the herd examined at least twice a year by a skilled veterinarian. Promptly remove from the herd any animal suspected of being in bad health, and reject her milk. Never add an animal to the herd until certain it is free from disease, especially tuberculosis. Do not move cows faster than a comfortable walk while on the way to place of milking or feeding. Never allow the cows to be excited by hard driving, abuse, loud talking, or unnecessary disturbance ; do not expose them to cold or storms. Do not change the feed suddenly. Feed liberally, and use only fresh, palatable food; in no case should decom- posed or moldy material be used. Provide water in abundance, easy of access, and always pure ; fresh, but not too cold. Salt should always be accessible. Do not allow any strong flavored food, like garlic, cabbage, and turnips, to be eaten, except immediately after milking. Clean the entire body of the cow daily. If hair in the region of the udder is not easily kept clean it should be clipped. Do not use the milk within 20 days before calving, nor for 3 to 5 days after- wards. MILKING. The milker should be clean in all respect ; he should wash and dry his hands just before milking. The milker should wear a clean outer garment, used only when milking, and kept in a clean place at other times. Brush the udder and surrounding parts just before milking, and wipe them with a clean, damp cloth or sponge, then wash the hands thoroughly. Milk quietly, quickly, cleanly, and thoroughly. Cows do not like unnecessary noise or delay. Commence milking at exactly the same hour every morning and evening, and milk the cows in the same order. Throw away (but not on the floor — better in the gutter) the first few stx-eams from each teat ; this milk is very watery and of little value, but it may injure the rest, as it is high in bacteria. If in any milking a part of the milk is bloody or stringy, or unnatural in appearance, the whole mess should be rejected. Milk with dry hands; never allow the hands to come in contact with the milk. A little vaseline may be used on the hands. If any accident occurs by which a pail full or partly full of milk becomes dirty, do not try to remedy this by straining, but reject all this milk and rinse the pail. CARE OF MILK. Remove the milk of every cow at once from the stable to a clean, dry room, where the air is pure and sweet. Do not allow cans to remain in stables while they are being filled. Strain the milk through a metal gauze and a flannel d!oth or layer of eottoq ^9 soon ^.s it is drawn, THE MILK SITUATIOlSr IN THE DISTEICT OF COLUMBIA. 319 Aerate and cool the milk as soon as strained. This must be done in pure air, and it should then be cooled to 45° if the milk is for shipment, or to 60° if for home use. Never close a can containing warm milk which has not been aerated. If cover is left off the can, a piece of cloth or mosquito netting should be used to keep out insects. If milk is stored, it should be held in tanks of fresh cold ice water (renewed daily), in a clean, dry, cold room. Keep the night milk under shelter, so rain can not get into the cans. In warm weather hold it in a tank of fresh cold ice water. Never mix fresh warm milk with that wMch has been cooled. Do not allow the milk to freeze. Under no circumstances should anything be added to milk to prevent its sour- ing. Cleanliness and cold are the only preventives needed. All milk should be in good condition when delivered. This may make it nec- essary to deliver twice a day during the hottest weather unless the milk is kept iced. When cans are hauled far, they should be full and carried in a covered spring wagon or blanketed. In hot weather cover the cans, when moved in a wagon, with a clean, wet blanket or canvas. THE tTTENSILS. Milk utensils for farm use should be made of metal and have all joints smoothly soldered. Never allow them to become rusty or rough inside. Clean all dairy utensils by first thoroughly rinsing them in warm water; then clean inside and outside with a brush and hot water in which a cleaning ma- terial is dissolved ; then rinse, and, lastly, sterilize by boiling water or steam. Use pure water only. After cleaning, keep utensils inverted in pure air, and sun if possible, until wanted for use, unless kept in a steam box. Office of Inspectoe of Milk, Providence, R. I. To the milk dealers of the city of Providence: Your attention is respectfully called to the following sections of the general laws and to the suggestions offered by this department, which must be carefully followed : Chapter 147, section 6: "No person shall sell or exchange, or have in his possession with intent to sell or exchange, or offer for sale or exchange, adul- terated milk or milk to which water or any foreign substance has been added." Chapter 1342, section 4 : " The board of aldermen of such city shall have the power at any time, in their discretion, upon the complaint of the inspector of milk or of any other person,- to revoke or suspend any such license for any vio- lation of the provisions of said chapter 147 of the general laws or of any act in amendment thereof or in addition thereto, or for any other good and sufficient cause or when the interest of the public health demands it." If you have any doubt as to the quality of the milk you are buying, we shall be glad to analyze from time to time any samples you may bring to this office. If you find it profitable to sell milk, you will find it still more profitable to handle a good article. If you can not aiTord to take time to handle your milk properly and inform yourself as to its quality, you have no right to be in the milk business. Failure on your part or the part of your dairymen to comply with the pro- visions of chapter 147 of the general laws, entitled " of milk," or with the inclosed suggestions will lead to the revocation of your license to sell milk. Very respectfully, yours, Waltee O. Scott, Inspector of Milk. 320 THE MILK tilTUATION IN THE DISTRICT OF COLUMBIA. Office of Inspector of Milk, Providence, R. I. Tour attention Is respectfully called to the following suggestions, which are offered in the hope that the quality of milk sold in this city may be improved : Keep the milk clean and cold. Mix your milk thoroughly before each sale. Clean all measures and scald them daily with boiling water. In warm weather rinse out your measures and mixing can occasionally with water. Keep all milk and milk measures in a clean, sweet ice box at all times when you are not selling from the same. Always keep the milk cans and measures covered to prevent dust, and with it the disease-breeding bacteria, from contaminating the milk you are selling. Milk cans must not be used for any purpose other than for the sale of milk. Failure to comply with these suggestions may lead to a revocation of your license to sell milk. Very respectfully, Waltee O. Scott, Inspector of Milk. Office of Inspector of Milk, Providence, R. I. To the milTc dealers of the city of Providence: Your attention is respectfully called to the following suggestions, which must be carefully followed if the milk which you sell is to contain less than 100,000 bacteria in a cubic centimeter : The stables must be kept clean and should be whitewashed at least once a year. The cows must be groomed daily and be free from disease. The hands of the milkers must be washed immediately before milking, and all milking must be done with dry hands. The first milk from each teat must be rejected and not collected in the milk pail. All milk utensils and strainers must be thoroughly cleansed by the use of boiling water, and all cans and bottles must be sterilized before they are again used. All milk cans must be kept covered to prevent dust and flies from contami- nating the milk. Milk utensils and cans must not be left to air by the dusty roadside, near the sink-drain outlet, the pigsty, or the open privy vault. All milk must be rapidly cooled and continuously maintained at a temperature below 50° F. Failure on your part or on the part of your dairymen to comply with these suggestions may lead to a revocation of your license to sell milk. Very respectfully, Walter O. Scott, Inspector of Milk. Office of Inspector of Milk, ^ Providence, R. I. seasons for the suggestions offered by this department. [The facts contained in this circular have been taken from official publications.] To the milk dealers of the aity of Providence: Your attention is respectfully called to the following suggestions offered by this department, intended to improve the quality of the milk offered for sale in this city, to prevent the spread of infectious diseases, and for the protection of the public health. The importance of a clean milk supply is recognized by all intelligent people and should require no argument. It has been my expe- rience that every milk dealer feels that his milk is the best that can be ob- tained, and to this overconfidence and failure to carefully follow the sugges- tions offered by this department every complaint against the purity of our milk supply can be traced. With clean, healthy cows, clean hands, properly THE MILK SITUATION IN THE DISTKICT OF COLUMBIA. 321 Sterilized pails, cans, bottles, strainer and milk utensils, absence of flies and dust in the air to which the milk is exposed, rapid cooling, and continuous main- tenance thereafter at a temperature below 50° F., clean milk can be produced. It must be evident that it is not difficult to produce clean milk if the sugges- tions are followed intelligently. It is a'bsoliitely imperative that the cows producing the milk be free from disease. — For the protection of the dairy herd diseased cattle should be promptly eliminated. Everyone will agree that the milk from cows suffering from any disease of the udder should be discarded. Careful experiments performed by many trained and eminently responsible investigators have demonstrated be- yond reasonable doubt that tubercle bacilli (germs which Cause tuberculosis) at certain times may be present in the milk of cows which show no signs of tuberculosis by means of physical examination, yet are proved to be diseased by the tuberculin test. This is explained by reason of the fact that cows which have tuberculosis in the lungs swallow their saliva, together with the organisms responsible for the disease, which pass, together with the food, through the intestinal tract, and in this way are found in the manure and get into the milk. Various foreign commissions have been appointed, and the results of their in- vestigations would seem to show that tuberculosis in animal and man is iden- tical. The department advises all producers, for their own protection and for the protection of the health of their customers, to have their cattle tested with tuberculin by a competent veterinarian at once. Cotvs must be groomed daily. — Most of the bacteria found in milk comes from the body of the dirty cow and indirectly from the intestinal tract. It is this visible filth which falls into the pail while the cow is being milked. To limit the amount of fine dust, hairs, and scales from the body of the cow which dur- ing the process of milking get into the milk, covered pails were invented. Since the bacteria are so small that they can not be filtered, at least by cotton and cheesecloth, once they are in solution, it is absolutely necessary that they be not allowed to fall into the milk. It is only the visible filth, such as straws, hairs, hayseed, scales, and large pieces of manure, etc., which remains on the surface of the cotton or ordinary strainer cloths, while most of the soluble filth and the bacteria which come from the intestinal tract pass into the milk. Many of the so-called sanitary pails containing numerous pieces of cheese-cloth and cotton through which the milk must pass, instead of removing the bacteria are found in fact upon examination to increase the number, since the continu- ous streams upon the sediment washes all the bacteria and soluble filth into solution. The amount of dust and dirt which can fall upon the surface of the milk pail will depend upon the cleanliness of the cow first of all, and then upon the area of the collecting surface. Numerous experiments by agents of the Bureau of Animal Industry have shown that milk from tuberculous cows, even when the udders were not diseased, are infected with tubercule bacilli from the manure of the animal. These experiments show that great care is necessary in guarding milk from contamination with particles of dry manure, stable dust, and dirty hairs from the body of the dirty cow. It is, therefore, absolutely necessary that the cows be clean. This cleaning should be done at least one- half hour before the cows are milked, and should be done thoroughly. An old currycomb or a card and an ordinary stable brush will usually serve for the purpose. In some cases the cow's udders and teats must be washed, and if this is found to be necessary the udders and teats should be thoroughly dried before milking is begun. The udder, teats, and parts of the cow which come directly over the milk pail should always be cleansed before the cows are milked with a clean, damp piece of sacking or a towel, and then the hands must be washed thoroughly. The cloths used for this purpose should be washed and kept clean. Stables must be kept clean. — It is certainly necessary to brush down from time to time the cobwebs and dry manure dust which may have accumulated upon the interior of the cow stable, and to sweep up any dry material that may be scattered over the stable fioor that the drafts of wind may not dislodge it and blow it into the milk pail. If one will stand where the rays of sunlight pass through the window into a room which is being swept and notice the visible dust particles in the air it will be evident that no sweeping be done in the stable dtiring milking; and that at least one-half hour must elapse after sweeping the floors or cleaning the cows before the milk pails are brought into the stable and milking begun, in order that the dust may settle upon the floor and not fall into the milk pails and thereby contaminate the milk. 82444°— S. Doc. 863, 61-3 ^21 322 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. Stables should te whitewashed at least once or twice a year. — A little lime, water, an old brush, and a pail is all that is necessary. Whitewash is a good disinfectant. It sweetens the air of the stable and makes it lighter. Windows are desirable in stables and dairy buildings because most varieties of bacteria are killed in a few hours by direct sunshine. For this reason the lighter the stable the better. The hands of the milkers must he washed immediately before milking, and all milking must he done with dry hands. — Though this is self-evident, never- theless many dairy employees take no precaution to keep their hands clean, and the milker who washes his hands just before milking is begun is the excep- tion and not the rule. The word " immediately " is very important. Numerous epidemics of typhoid fever have been traced to infected milk and have had their first start from hand infection. The milker may have a mild attack of typhoid fever, or be in the early stages of a severe attack, or perhaps he may be one of those unfortunates, a typhoid carrier, unfortunate for the community if not for himself. In the act of milking he may wash at least some germs into the milk pail, especially if he squirts the milk upon his palms preliminary to milking. The hands may be soiled by acting as a nurse for some case of typhoid in the family, by emptying or burying the discharges of the patient, or by sharing the family towel with some member of the house- hold who is acting in this capacity. He may be convalescent from scarlet fever or diphtheria, or his hands may come in contact with those who have it. It is easily seen how infective material upon the hands may find its way into the milk and cause sickness for those that drink it. It would seem to be absolutely necessary that those engaged in the milk business be free from contagious diseases themselves and have no contact with those suffering from them. Milkers should never commence milking without washing their hands. Dealers should not fill bottles and cap them until they have performed this exceedingly important part of their toilet. The depart- ment recommends that the hands by cleansed by the liberal use of soap and water, after which they should be thoroughly rinsed, and dried with a clean towel. The first milk from each teat must be rejected and not collected in the milk pail. — Nearly every case of garget is due to bacterial infection of the udder through the teat. The teats, when the cows lay down, come in contact with the stable floor, which can not be always kept perfectly clean. In this way the organisms infect it. By discarding the first stream from each teat any bacteria in the fore milk can be washed into the gutter and not into the milk pail. The first milk is always very poor, and in cases of infection high in bacteria. Milk utensils and strainers must be thoroughly cleansed by the use of boiling ivater and all cans and bottles must be sterilised before they are again used. — The washing of milk utensils would seem to be a very simple operation. You may perhaps have noticed that a milk can or pail which has been used as a container for milk and left standing around the house or dairy, after it has been supposed to be thoroughly cleansed and scalded, will many times have an offensive smell. This would not be possible if the container had been properly cleansed and sterilized. The reason milk producers have adopted the system of putting their utensils in the yard to air is to allow the bad odor to escape, which is caused by the bacteria decomposing the dirty material and wash water left in most milk cans. When warm milk is put into rusty cans and cans which are not properly constructed and the joints of which are not well soldered, the dirty material left in the rusty pits and unsoldered joints is dissolved and the bacteria liberated and thus enabled to decompose the warm milk. The way to clean dairy utensils is first to rinse them in luke-warm water, then clean thoroughly inside and outside with a brush and hot water in which the cleansing material is dissolved, then thoroughly rinse with plenty of clean water, and lastly sterilize with boiling water or steam. Milk utensils should always be sterilized by keeping them in water continually boiling for at least 30 minutes. Confined steam under 15 pounds pressure in a steam sterilizer will kill all germs known in 15 minutes. The general laws of this State, chapter 173, section 19, make it a crime for any person, firm, or corporation to ship, return, or deliver to any producer, dealer in, or consumer of milk, any can, jar, bottle, measure, or other vessel used as a container for milk without first thoroughly cleaning and cleansing by the use of boiling water, steam, or other proper agent. Clean milk in sterile bottles, handled by persons free from disease, is the ideal way to deliver milk, but when cans and bottles are left at homes where there are cases of scarlet fever, typhoid THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 323 fever, or diphtlieria, and filled by the dealer, contrary to law, without being thoroughly cleansed and properly sterilized, they are a source of danger. The constant presence of many mild cases of disease — so mild that a correct diagnosis is not made by the physician — makes it imperative that no bottles or cans be refilled until they are thoroughly cleansed and sterilized. Every licensed dealer in this city distributing milk in cans and bottles has the proper equipment to do this work, and any epidemic of contagious diseases from improperly sterilized cans and bottles will be due to willful negligence. Milk producers must not be allowed to use sterile cans intended for our city milk supply as pails to bring water for cattle, or for any other purpose on the farm. Milk cans must be kept covered to prevent dust and flies from contaminating the milk; milk utensils and cans must not 6e left to air 'by the dusty roadside, near the sink-drain outlet, the pigsty, or the open privy vault. — Milk cans should be covered with a clean canvas or blanket, used only for that purpose, when they are being carted over the road, that the dirt and manure dust in the highway may not settle upon them and get into the milk can and contami- nate the milk when the wooden stoppers and covers are removed. No good reason can be given why milk should remain in the barn unneces- sarily exposed to contamination with the foul odors and manure dust of the stable for any material period of time. On nearly every farm there are enough old boards which could be nailed together to make a suitable milk room into which the milk should be carried immediately after it is drawn from the cow. The reason for such a building must be evident. Insects play a large part as mechanical carriers of disease germs, the greatest menace to our daily life being the common house fly known to scientists as the typhoid fly. It breeds in manure and it feeds on it; it feeds on the sputum of diseased throats and on typhoid dejecta, and by means of its hairy feet and legs it carries about and distributes particles of these vile feasts, which fre- quently contain living germs capable of producing a new case of disease. In still another way does the fly spread disease — germs taken into its body in food are known to remain alive in the intestines, and also for days after they are ejected in the " specks," i. e. in the fly excrement. Recent experiments with animals have proved this to be true of both tuberculosis and typhoid, the germs in the " speck " having actually given the disease from 9 to 15 days after being voided by the fly. Flies were the principal carriers of the typhoid fever which attacked 20 per cent of the United States soldiers in the Cuban War and furnished 86 per cent of the deaths. It is not possible to prevent flies from visiting the dairy or farm, but the stable manure need not be allowed to accumulate and furnish breeding places for them. It will be found far more valuable if used to increase the fertility of the soil. It is certainly not necessary to allow flies to infect the milk pail and milk utensils and swim in the milk. There certainly can be no reason why they should be allowed to dine in the open privy vault or drink at the sink drain ; the vault can be covered and a covered cesspool can be provided. Would not these precautions deprive them of their vile feasts and help to prevent the spread of disease? They can be easily kept out of the milk utensils by the use of screens for the dairy windows. All milk must be rapidly cooled and continuously maintained at a temperature 'below 50° F. Milk is quickly decomposed by bacteria unless it is kept cold. Bacteria, like other forms of plant life, can not grow in cold weather, so these minute germ plants are prevented from multiplication by keeping the milk cold. If everyone had his own cow and used the milk as soon as it was drawn there would be no great need of cooling the milk. Milk for all large cities must be held at the farm, shipped OA^er country roads, transported by train, and k6pt in the city bottling plant before it is delivered at the home of the consumer. For this reason it is absolutely necessary that the greatest care be taken to quickly cool the milk at the farm immediately after it is drawn from the cow and keep it cold, in order that it may not contain dangerous numbers of bacteria. The law makes it a crime to sell adulterated milk, but it would seem to be a still greater fraud to sell milk which can not be used at all when delivered to the customer, due to the slovenly methods of handling and improper cooling. Few wells and springs are cold enough in the summer to cool milk to 50° F. For this reason ice must be used in hot weather, and a liberal supply should be provided. The work of Nathan Straus in New York City in dispensing pasteurized milk for infants in general proves that the bacteria which are always found in 324 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. excessive numbers in old, improperly cooled, dirty milk are to a great extent responsible for the liigh death rate and infant mortality in cities. Prior to the beginning of this work in 1893 the death rate of children under 5 years in New York City was 96.2 in every 1,000, and in June, July, and August, when exceptional care must be taken to properly cool the milk, the death rate was 136.4 for each 1,000. With the increased use and distribution of pasteurized milk in 1906 the death rate fell to 55 per 1,000, and in June, July, and August the death rate was 62.7 per 1,000. This means that thousands of lives were saved. The milk supplied was from the same farms, the same kind of herds, and was distributed in the same way, the only difference being that the bottles were sterilized and the bacteria in the old, dirty, warm milk were killed by the heat applied to pasteurize it, and it was then properly cooled. If the sug- gestions offered by this department were carefully followed by milk producers and dealers pasteurization of milk would not be necessary. These suggestions are based upon fact and experience, and are offered in hope that they may improve the quality of the milk you are selling. It takes but a little more time each day to conduct your business in a decent manner, and you will find that the extra labor has been well expended. If you find it profitable to sell milk you will find it still more profitable to handle a clean, pure article. If you can not take the time to conduct your business in a decent manner and inform yourself as to its quality you have no right to be in the milk business. Very respectfully, Walter O. Scotx, Inspector of Milk. Office of Inspector of Milk, Providence, R. I. To milJc producers: The department of milk inspection, with the cooperation of milk producers, offers the inclosed suggestions, which if intelligently followed would improve the sanitary conditions existing at the dairy farms from which our supply is obtained and indirectly improve the quality of the milk offered for sale in this city. The fact that dirty milk has been held by physicians to be one of the principal causes of the high death rate and infant mortality makes it important that only clean milk be sold. The general laws of this State and the pure-food law of the United States prohibit the sale of milk containing foreign substances. The courts have held that the sale of milk containing sediment — viz, dirt, hairs, putrid matter, and manure— is a violation of the law. For the education of your employees it is important that the inclosed sugges- tions be posted conspicuously in the stable or milk room. In the near future agents of this department will visit all dairy farms from which milk is shipped to Providence, for the purpose of seeing that the sugges- tions are being carried out. Samples of milk shipped to this city by producers will be examined to determine if the laws of this State are being complied with. I hope that the inclosed suggestions may be of assistance in enabling pro- ducers to ship only clean milk. Very respectfully, yours, Walter O. Scott, Inspector of MilJc. [To be posted in all dairies.] Department of milk inspection of the city of Providence offers the follow- ing suggestions which should be carefully followed by farmers and dairymen in the care of cows and handling of milk : the barnyard. 1. It should be well drained, clean, and dry and should be as much sheltered as possible from the wind and cold. There should be no pools of stagnant water or urine therein, 2. Manure should not be allowed to collect in the barnyard and should not be at any time in contact with the stable or milk house. THE MILK SITUATION IN" THE DISTRICT OP COLUMBIA. 325 THE STABLE. 1. Cow stables should be well lighted and ventilated. The ventilation should preferably be from the top. 2. There should be at least 400 cubic feet of air space for each cow, other- wise extra ventilation should be provided. 3. Walls and ceilings should be kept clean. The stable should be white- washed twice a year, and more often if necessary. 4. It is desirable that the place where the cows are kept be used for no other purpose. A cow barn should not be used as a storage place for straw, hay, or other feeds, or as a wagon or tool house, as the dust and dirt which accumu- lates in a place of this character is liable to drop into the milk while it is being drawn from the cow. 5. The ceilings should be so constructed that dust and dirt therefrom shall not readily fall to the floor or into the milk. If the space over the cow is used for storage of hay, the ceiling should be made tight to prevent chafC and dust from falling through. 6. Stable floors should be made tight and smooth and be of some nonabsorb- ent material. Dirt or earth floors and gutters can not be tolerated. 7. The flooring where the cows stand should be short enough so that all manure will be dropped into the gutter and not upon the floor itself. 8. The floor should be swept every day but not before milking. 9. Cement gutters and mangers are the best, as they can be more easily kept clean than if made of wood. 10. The manure gutter should be from 6 to 8 inches deep, and should be kept at all times fairly free from manure. 11. Manure should be removed from the stalls and gutters before the morn- ing milking and also before the afternoon milking, where the cows remain in the stable all day. 12. The use of land plaster or lime is recommended in the gutters. 13. Allow no strong smelling material in the stable for any length of time. Store the manure under or outside the cow stable and remove it to a distance as often as practicable. 14. If individual drinking basins are used for the cows they should be fre- ' quently drained and cleaned. THE cows. 1. The cows should be kept clean and be free from disease. 2. Have the herd examined at least twice a year by a skilled veterinarian. Never add an animal to the herd until certain it is free from disease, especially tuberculosis. 8. Promptly remove from the herd any animal suspected of being in bad health and reject her milk. 4. The cows should be groomed daily and collections of manure, mud, or other filth should not be allowed to remain upon their flanks, sides, udders, or bellies. 5. The clipping of long hairs from the udder and the right side of the cow is of assistance in preventing the collection of filth which may drop into the milk. 6. The hair on the tails should be cut so that the brush will be well above the ground. 7. The cows may be bedded with sawdust, shavings, leaves, straw, or some equally clean material. 8. The use of horse manure for bedding is to be condemned. Sand or loam must never be used as bedding. 9. To prevent the cows from lying down and getting dirty between cleaning and milking, a throat latch of rope or chain should be fastened across the stanchions under the cow's neck. THE FOOD. 1. Feed liberally, and use only fresh, palatable feed stufCs. In no case should strong smelling or decomposed or moldy material be used. 2. Do not allow any strong-flavored food, like garlic, cabbage, and turnips, to be eaten by milch cows. 3. Provide water for cattle in abundance, easy of access, always pure and fresh. 4. Salt should always be accessible. 326 THE MILK SITUATION IN THE DISTUICT OF COLUMBIA. THE UTENSILS. 1. Milk utensils for farm use should be made of metal and well tinned and have all joints smoothly soldered. Never use them if they become rusty or rough on the inside. 2. Dairy utensils should be cleansed directly after using by first thoroughly rinsing them in water; then clean inside and out with hot water in which a cleaning material is dissolved ; then thoroughly rinse with plenty of water ; and lastly, sterilize by boiling water or steam. Use pure water only, 3. All milk utensils and strainers should be thoroughly cleansed by the use of boiling water ; and all cans, utensils, and strainers must be sterilized before they are used. 4. Milk strainers should be kept exceedingly clean, and scalded a second time just before using. If cloth strainers are used, several of them should be provided in order that they may be frequently changed during the straining of the milk. 5. After cleaning utensils should be inverted in pure air. Milk utensils and cans must not be left in the cow stables, by the dusty roadside, near the sink drain outlet, the pig sty, or the open privy vault. 6. Ice tubs and cooling tanks should be thoroughly cleansed by scrubbing at least once a week. 7. Remember that the milk cans are the property of the city milk dealer, and must not be used to carry water for cattle or for other uses on the farm. THE MILKING AND MILKEES. 1. No person having any communicable disease, or one caring for persons having such disease, should be allowed to handle the milk or milk utensils or assist in the milking. 2. The hands of the milkers should be carefully washed immediately before milking. The hands should be thoroughly washed with soap and water and carefully dried on a clean towel. 3. Milk with dry hands. Never allow the hands to come in contact with the milk. The practice of moistening the hands with milk, or to spit on them, is to be condemned. 4. The milker should wear a clean washable jacket, used only when milking, and kept in a clean place at other times. 5. Always brush off and wipe the udder and surrounding parts just before milking. If the cows are very dirty, wash with a cloth or sponge, and then dry the udders and teats with a clean piece of cloth or sacking. 6. Milk quietly, quickly, cleanly, and thoroughly. 7. The first few streams from each teat should be rejected, as this milk contains more bacteria than the rest of the mess. 8. All milk drawn from the cows 30 days before and 10 days after calving should be rejected, and also all milk from diseased cows. If any accident occurs by which a pail full or partly full of milk becomes dirty, do not try to remedy this by straining, because the soluble filth and the bacteria can not be removed by straining, but reject all this milk and rinse the pail. 9. The pails in which the milk is drawn should have as small an opening at the top as can be used in milking. This renders the collection of manure and dust with the milk less likely. 10. Dry fodder should not be fed to the cows during or just before milking, as dust therefrom will fall into the milk. THE MILK. 1. Remove' the milk of every cow at once from the stable to the milk house or to a clean room, where the air is pure and sweet. Do not allow milk cans to remain in stables while they are being filled. 2. A good plan, if modern coolers are not available, is to strain the milk into cans which are standing in ice water which reaches the neck of the can. 3. The more rapidly the milk is cooled and the colder it is kept the safer it is and the longer it will remaia sweet. Milk can not be properly cooled at any season of the year if the air alone is expected to do the cooling. 4. Ice should be used in cooling, both in summer and winter, as very few wells or springs are cold enough for the purpose. 5. If aerators or coolers are used, they should stand where the air is free from dust and odor, and on no account should they be used in the cow stable. THE MILK SITUATION IN" THE DISTRICT OF COLUMBIA. 327 6. Milk should always be cooled as soon as strained. If modern apparatus for airing and cooling at tlie same time is not at hand, the milk should be aired by tipping the covers slightly while cooling the milk to 50° F. in clean ice water. Precautions should always be taken to see that the water is above the milk to be cooled in the cans and that the water can not overflow into the cans and water the milk. 7. Never ship a can containing warm milk which has not been cooled and aerated. 8. II; the milk is held at the farm it should be stored in fresh, cold ice water or kept in a running spring. 9. The milk should always be kept under shelter so that the rain can not get into the cans. 10. Never mix fresh warm milk with that which has been cooled. 11. During the transportation of the milk and cans to the car or dairy, cov- ered wagons only should be used. If this is not possible the cans should be protected from heat, cold, dust, and mud by a clean canvas or blanket. 12. All milk must be rapidly cooled and continuously maintained at a tem- perature below 50° F. Office of Inspector op Milk, Providence, B. I, To millc producers: The department of milk inspection, with the cooperation of milk producers, hopes to improve the sanitary conditions existing at the dairy farms from which our city supply is obtained. To accomplish this end and to assist milk pro- ducers in removing objectionable features, the department has adopted a dairy score card, issued by the United States Department of Agriculture, a copy of which is inclosed. In the near future agents of this department will visit all dairy farms from which milk is shipped to Providence and score them in accordance with the adopted score card. It will be to your advantage to make such changes as will enable you to obtain as high a score as possible. Very respectfully, Walter O. Scott, Inspector of MilJe. Department of Milk Inspection, Providence, R. I. To milk dealers and milk producers: The department of milk inspection has adopted regulations intended to pro- hibit the sale in the city of Providence of milk which contains an unnecessary or dangerous number of bacteria. The investigations of the department have shown that milk properly col- lected and handled does not contain a large or dangerous number of bacteria. This circular is issued so that those who are interested in the production and sale of milk may adopt such precautious as are necessary to prevent the milk being condemned, because it has been rendered unfit for use by the growth of large numbers of bacteria in it. BACTERIA AND THEIR GROWTH IN MILK. Bacteria are among the smallest and simplest of all living things. They much resemble the cells of which plants are composed, and, like plants, require moisture, warmth, and food to grow. When these conditions are present they multiply very rapidly, so that from one germ a few hundred may be produced in an hour, millions in 12 hours, and billions in a day. As bacteria increase in numbers, they gather nourishment from the milk or other substances in which they develop, and, like other higher forms of life, transform what they take into their bodies into useless or poisonous products. They thus both rob the food of its nutritious substances and add others to it which are more or less poisonous. Thus, milk becomes sour through the change of its milk sugar into acid, produced by bacteria. But long before milk be- comes sour to the taste it may contain enormous numbers of bacteria and has already become unwholesome and dangerous when employed for food, especially lor young children. 328 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. The bacteria or germs which cause the various infectious diseases, such as typhoid fever, scarlet fever, diphtheria, consumption, etc., readily live • and multiply in milk, and outbreaks of these diseases have been frequently traced to contamination of milk by careless farmers or milkmen, who have infected the milk with disease germs from their hands, from improperly sterilized bottles or cans, from polluted water, or from other sources, either while themselves sick or recovering from some one of these diseases, or while nursing others who were suffering from them. Many thousands of cases of illness and death have thus been produced from such causes. This is, of course, entirely unnecessary, and can easily be prevented. It is most important, therefore, for all persons who handle milk to know from what portion of the body these minute germs are given off, so that they may adopt the necessary precautions to prevent infection of the milk. The germs which cause scarlet fever are thrown off in the discharges from the nose and throat and in the scaling from the skin. Those which cause typhoid fever are found in the urine and feces, and thus often reach the spring or well water with drainage which has leaked into it. Those which cause consumption and diphtheria are contained in the expectoration. The germs from cows which are diseased, especially when affected with consumption and tuberculosis of the udder, may also infect the milk and produce sickness in those who drink it. The bacteria which cause milk to sour and ferment and so become unwholesome are derived from manure and dirt which drop into the milk pail from the cow's belly or udder or tail, or from the dust of the barn, or from the dirt off the milker's hands, or they are contained in the pails and dirty strainers and cans, which have not been thoroughly cleaned and sterilized after having been previously used for milk. The pails into which the milk is drawn should not be of the large, open-top variety, but should be covered with as small an opening at the top as can be used in milking. If eveiyone would use covered milk pails much of the dust and dirt which falls into the milk during the process of milking would be prevented and fewer bacteria would be found in the milk. When milk is collected under cleanly conditions, the number of bacteria which fall into it is much less than when the conditions are dirty. Milk affords one of the best foods for the growth of bacteria. When fresh, however, it contains substances which retard somewhat the development of bacteria for a few hours, if they are not too numerous, but we depend upon low temperatures to further limit changes in it. Just as large forms of plant life can not grow in cold weather, so also these minute germ plants are pre- vented from multiplication by cold. For this reason all milk should be rapidly cooled and kept cold until used. Bacteria found in milk generally multiply most rapidly at blood heat, and cease to multiply at all at the freezing temperature. Any reduction of the temperature below 95° F. limits the rapidity of growth, but it is not until the temperature is reduced to 45° or 50° F. that the growth is nearly arrested. At 32° F. milk remains unchanged for an indefinite period. In fresh milk, properly collected and quickly cooled at 50° F. and kept at this temperature, during the first 24 hours there is no increase in the number of bacteria ; after 24 hours the peculiar properties of fresh milk to resist the growth of bacteria become exhausted, and the bacteria also become gradually accustomed to the cold, so that even at this temperature they may rapidly increase and in a few days cause the milk to become sour. It is impossible to obtain cow's milk under the ordinary conditions which exist in most milk barns without allowing some bacteria (which always abound in the dirt and dust of the barn and on the cattle) to drop into it, but the num- ber may be limited. It is wholly unnecessary and inexcusable to permit the germs of the diseases of human beings or cattle to contaminate the milk. The fewer bacteria found in milk the more wholesome it is, and when the number becomes very large, the milk becomes not only unwholesome but dangerous, and the use of such milk is the commonest cause of the diarrheal diseases of children, particularly prevalent in summer. The importance of this may be appreciated when it is known that 1,188 deaths occurred from the diarrheal diseases in the city of Providence among children under the age of 2 years during the last five years (1902 to 1906, inclusive). Under present conditions considerable time must elapse before the milk reaches the consumer, and before it is used, and if it is not very carefully handled and kept cold the number of germs contained in it when used becomes very large and sometimes almost incredible. There may be at the end of a THE MILK SITUATION IIST THE DISTKICT OF COLUMBIA. 329 day or two millions of bacteria in a teaspoonful of milk not properly collected and cooled. As the milk must often be kept in the house for 12 hours or more after it is delivered and before it is consumed, it naturally becomes still more unwholesome before being used, and it therefore becomes important that all of the milk sold in the city should reach the consumer in good condition and be kept cold after it is delivered. The number of bacteria in milk should be as low as is possible under the conditions under which practical dairy farming must at present be carried on. All milk dealers can easily produce and sell milk which has less than 500,000 bacteria in a cubic centimeter, or about one-fifth of a teaspoonful, which is the limit set by this department for clean milk. To keep within this limit the cattle, stables, and the milker's hands should be kept clean, and the pails and cans should be always scrupulously clean and properly sterilized. The milk should be immediately cooled at the farm and transported to the city with the least possible delay. So far as practicable, each day's milk supply should reach the city on the same day or not later than the following morning, and the temperature of the milk should be continuously maintained at 50° F. or less. The department of milk inspection, with the cooperation of farmers and all milk dealers, hope to improve the character of the milk sold in this city, so far as the nuniber of bacteria in it is concerned. It is a matter of great impor- tance to the health of everyone that our milk supply be clean and pure. This department will test samples of milk for the number of bacteria which they contain ; and where the number is found to be so great as to show that the milk has not been properly produced and handled, the dealers to whom such milk is shipped will be cautioned to notify the farmers who supply them to improve their methods. If then the milk is still found to contain dangerous numbers of organisms, the sale of the milk will be prohibited, and the board of aldermen will be requested to revoke the license of the dealer if necessary. Very respectfully, Walter O. Scott, Inspector of Milk. HOW TYPHOID FEVEB IS CAUSED. [This circular is based on one prepared by Dr. H. W. Hill, for tbe Minnesota State Board of Health.] Typhoid fever is an infectious disease. The infection is in the excrement and urine of the patient, and sometimes in the saliva. The patient after recovery often remains infectious for some weeks or months. No one ever catches typhoid fever except by getting into his mouth some of the excrement, urine, or saliva of one who already has, or has recently recov- ered from typhoid fever or is infected with the germs of the disease. At first sight it might seem that this can not be true, for no one would ever take will- ingly or knowingly any of these things into the mouth. But, as a matter of fact, people are continually catching typhoid fever from others, always in just this way — never in any other way. If one will stop and think carefully about it, he will see that this disgusting way of " catching " typhoid fever is not only possible, but can and must happen all the time ; and is in fact the only way the disease is carried. For instance, the discharges of a patient thrown out or buried in gravelly soil near a well may soak through the soil into the well, or the discharges may be thrown or washed into a stream. The persons who drink water from such a well or stream drink the discharges also, much diluted it is true, and of those who drink such water some become infected. But the water route is only one of the many ways in which excrement, urine, and saliva pass from the patient into other people's mouths. The most common of the routes other than water is by way of the hands, and a few of the ways that infection travels by the hands are given here in detail. One may never have thought of these, but once thought of they can never be forgotten again because the whole thing is so plain, and so disgusting. There is nothing mysterious about the transmission of typhoid fever. The patient. — To begin at the beginning. A typhoid patient is usually help- less, and everything must be done for him — he must be washed, his nose and mouth wiped, and his bedclothes changed by some one else. He must be fed and given medicines by an attendant ; he must have a bedpan or urinal placed 330 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. in position and removed as necessary. Often he requires injection into the bowel ; sometimes he has involuntary discharges before a bedpan can be placed in position. Sometimes his temperature must be taken in the bovpel. After the use of the bedpan or urinal it is difficult to clean his body thoroughly, and even after avi amount of washing which removes all visible dirt, the infection remains as numerous particles of matter on the skin or sheet or night clothes. As the patient tosses about in bed these particles are spread from skin to sheet and back again, until the whole lower part of the patient's body and legs be- come infected with more or less particles of excrement and urine — very small particles and very thin, no doubt, leaving not even a stain to show their pres- ence, but present all the same. A particle of excrement, spread out upon the skin so thin as to be invisible, may contain millions of the bacteria which produce the disease. Dangers to the attendant. — It must be perfectly clear to everyone who con- siders these facts for a moment that no attendant can touch the body or bed- clothes or urinal or bedpan or injecting syringe or thermometer or anything else which comes into contact with the patient's body or legs or sheets, without great chance of transferring at least a few of these bacteria to the hands. Now, everyone's hands go often to the lips and mouth every day, consciously or unconsciously. Watch anyone and see, or notice how often you do this your- self. If there be on your hands any of the discharges of a typhoid patient, consider how extremely likely it is that you will transfer them to your mouth. Dangers to visitors. — The patient's ovsti hands also touch his own body, his own sheets, etc., as much or more than the attendant's hands do, and the pa- tient's hands therefore become infected likewise. The patient touches his own face, pillow, books, medicine glass, spoons, plates, etc., with his infected hands, and these, in turn, become infected. If the patient shakes hands with a visitor, or if the visitor touches only the patient's forehead with the fingers, infection is likely to be transferred to the visitor's hands. Merely shaking up a pillow or settling the sheets to make the patient more comfortable is likely to infect the hands of the one who does it. Dangers from the nurse to others. — But the persons who come into contact with the typhoid patient directly are not the only ones who are in danger. Anyone who eats food handled by a person who has been in contact with the typhoid patient is likely to take into the mouth >the infected material from that person's hands ; for instance, it has happened over and over again that a hotel or restaurant waitress, nursing a sick relative and also waiting on table, has transferred typhoid fever from the patient to the boarder by handling the boarder's food just after she has emptied the sick person's bedpan. In private families the mother often acts as nurse for the sick person and at the same time prepares meals for the rest of the family. Pood. — The hands of the house nurse, infected with discharges from the pa- tient, transfer some of it to the bread as she slices it for the table, to the spoons, forks, plates, etc., as she lays the table; so, too, as she breaks up ice for the ice-water jug, or washes greens, or opens a can of fish or tongue, to be served cold. In 50 ways her hands touch utensils or go into food continually while preparing the meal. The handling of the food does no great harm, if the food is afterwards cooked and is not again handled before it is served, because the heat of cooking kills the infection, but the handling of cold foods or drinks which are not to be cooked is very dangerous to those who eat or drink them, while the handling of plates, cups, spoons, etc., is also dangerous because they go to the mouths of different members of the family. In fact, it is almost always true that if secondary cases develop in the family of a typhoid patient, these later cases get it from the first through the hands of the mother or who- ever else is nursing the patient. With a properly trained nurse, however, no such spread should occur, and it is not necessary that it should occur with any- one if the proper precautions are carefully followed. Direct handling. — Besides giving the disease to others through the food, the mother often directly puts her fingers into her children's mouths, perhaps to prevent them from swallowing a marble, perhaps to extract a piece of gum stuck to the teeth, perhaps to feel an aching tooth, or for other purposes. She, of course, is likely to wash their faces and hands, brush their hair, dress and undress them, and the infection on her hands, even if it does not go directly into their mouths, goes onto their hands, etc., and they, in turn, put their hands into their own mouths. These illustrations are sufficient to call attention to the dangers of hand infection from the nurse to the rest of the family. Dangers from helping the nurse. — Often, even when a trained nurse is in charge of a typhoid case and almost always when the mother or some other THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 331 relative is acting as nurse, members of the family, not regularly engaged in tlie nursing, " help out " by sitting with the patient at times, carrying out the soiled dishes, bedclothes, etc, or emptying the bedpans or urinals. The latter, es- pecially, is often done by the father or older brother. Those persons who thus assist, perhaps only by receiving a tray of dishes at the door and conveying it to the kitchen, run some risk; those who handle the bedclothes or empty the discharges, if careless, run great risk, even though they handle them for but a moment. Dangers from infected articles. — Another danger from a typhoid patient lies in the washing of the dishes, bedclothes, bedpans, urinals, etc. Often these are carried to the kitchen and allowed to remain piled upon the table or floor, per- haps mixed with the dishes, bedclothes, etc., of the rest of the family and washed with them. It is true that the usual process of washing clothes with soap and water, the clothes being boiled, will kill the infection, so that the clothing is free from danger after it is clean ; but there is also a real danger, first, to the person who does the washing, handling the clothes, etc. ; next, during the washing, the one who does it may, with her hands wet with the infected wash water, take up kitchen utensils, receive food from the delivery man at the door; possibly after a hurried drying on the kitchen towel (which she infects in the process so that the next person who uses it becomes infected also) she prepares some article of food or drink, wipes the dishes, lays the table, or otherwise spreads the infection about the place. (The writer has seen the common kitchen hand towel, after being used to dry the family hands, used also to dry the family dishes.) Flies. — ^Another possible danger to the family and neighbors consists in admit- ting flies to the sickroom or to dishes, bedclothes, or discharges in the sick- room or after removal from it. Flies may easily carry discharges upon their feet from the bedpan or bedclothes to the family food or drink. A fly's feet and legs are covered with small hairs, and particles of feces easily stick to these. If the fly with typhoid feces on his feet falls into the milk or walks over the cake, he leaves a trail of typhoid infection behind him. Hence the room and the whole house should, if possible, be well screened. If the slops or wash water are thrown upon the ground, the chances of infection are increased. So also if the privy vault is open or if the contents overflow. Not only may human beings get excrement on their feet, but hens may carry it to the doorstep, and the cat or dog may bring it into the house. The man who buries the discharges may carelessly get his feet soiled and carry infection into the house in this way. If he washes the bedpan or urinal at the pump, the washings may go through the curb or run in under it from the side, thus infecting the well. Precautions. — The trained nurse and the physician should know how to pro- tect themselves and should go through typhoid outbreaks without contracting the disease. This is done simply by always regarding everything in a patient's room as infectious and never handling anything that is in or comes from the patient's room unless it has first been disinfected. If it is impossible to avoid handling the material before disinfection — and, of course, it must be handled during disinfection — then always immediately disinfect the hands. These rules faithfully lived up to day by day, hour by hour, minute by minute, always and in every case will entirely prevent infection from spreading by way of the hands. Most important of all, it must be remembered that persons are infectious even before the disease is developed, and that many cases are up and about and are so mild that no doctor is called, or he fails to recognize it. Also remember that the germs may remain in the body long after recovery and are sometimes found in people who have never been sick. Perhaps the new hired man or a visitor or the summer boarder is such a " carrier " of germs. Therefore, as one can never tell when he will come in contact with typhoid germs, he should always be on his guard. Is it not worth while to try to not let any other person's excrement, no matter how tiny a speck, get into one's mouth, and to also try to not let one's own excrement get into another's mouth? It is not such a hardship, after all, to be clean. It may be asked how, if there are so may ways of infection, does anyone man- age to escape. As a matter of fact, the excrement is not always so teeming with bacteria ; they may be few at times, and they may not be evenly distributed, so that many particles contain none at all. Often even hurried washing removes practically all from the hands. The germs often die rapidly when exposed to light and air. People are not always and continuously so careless as has been described. They generally do wash their hands and do not always put the fingers in the mouth. Then, again, probably sometimes when only a few germs 332 THE MILK SITUATION IN THE DISTBICT OF COLUMBIA. get Into .the mouth, they are killed by the fluids of the body and can not gain a foothold. So, if all these points are considered, it is easy to understand how typhoid spreads as it does, and also why so many persons escape, though more or less exposed to the disease. A'boiit milJc inspection. — It very often happens that the father or brother who helps the nurse by emptying or burying the discharges also milks the cows. He is then very apt to transfer infection to the milk in the process of milking, for whatever he has on his hands is likely to go into the milk. If he strains the milk as he puts it into cans or bottles or helps to care for it in any way, he is equally likely to infect it. So, too, if he peddles the milk from cans. If the pails, cans, and straining cloths are washed in the house in the same sink or tub with other things or by any member of the family, infection may result. Many an outbreak of disease with scores of cases and many deaths has been traced to milk thus infected by a farmer's or dealer's lack of cleanliness. Many a farmer's business has been ruined and death has entered his own family in this way. A separate room should be provided for the care of milk and the washing of vessels. These should be sterilized by steam, if possible, and certainly by boiling water. Always thoroughly wash the hands before milking or handling milk. If typhoid fever occurs in the family of a milk producer or dealer, the patient should be at once removed from the premises or those who handle the milk should live away from the premises.

They eat the sputum on the sidewalk and revel in the garbage pail. Perhaps you think it is disgusting to read about such things, and so it is. But is it not more disgusting to have these same flies after their repast of fllth, drown in the milk pitcher, drop their specks on the frosted cake, or clean their feet on the bread? Is it pleasant to see the flies that very likely have just come from a neighboring privy crawl over the lips of the sleeping baby or gather on the nipple of its nursing bottle? Suppose the fly that was fished out of the milk pitcher had just been eating the excrement of a typhoid fever patient, would you like to drink the milk? Perhaps the flies that were walk- ing on the fruit which you purchased at the street corner had just been feeding on the sputum of a consumptive. Does it not seem likely that flies may spread disease? That is what many physicians and health officers think. Perhaps hereafter j^ou will screen the house and protect the food from flies. The young of flies are maggots. They seem to prefer to breed in stable manure. But they also breed in excrement of all kinds, in garbage, and in aU sorts of wet and filthy refuse. Do you want to raise these filthy insects, these germ carriers, to be a pest in your own house, and perhaps carry disease to your neighbors? Of course you do not. Then keep the stable manure closely covered and have it removed often — once a week in summer if possible. Keep the back yard and the alley clean. Allow no refuse to accumulate anywhere. After your own premises are in order talk over the matter with your neighbors, and get them also to read this circular. Pbovidence, 1909. BICHMOND, VA. AN ORDINANCE TO create the office of inspector of milk and food supplies, and to provide for the inspection of milk, meat, and other food supplies brought or offered for sale in the city of Richmond, and to prohibit the sale of adulterated or impure milk, meat, and other food supplies within the city of Richmond. [Approved June 9, 1904. — Sections 8 and 9 as amended Mar. 19, 1910.] Be it ordained Ity the council of the dty of Richmond (1) That it shall be the duty of the board of health, as soon as practicable after the passage of this ordinance, and biennially thereafter between the 1st day of October and the THE MILK SITUATION" IN" THE DISTRICT OF COLUMBIA. 333 1st day of November of such year to appoint an inspector of milk and food supplies to serve for the term of two years, unless sooner removed by the board of health, and thereafter until his successor is appointed and qualified accord- ing to law, who shall within 30 days thereafter qualify before the city clerk by entering into a bond in the penalty of $1,000 for the faithful discharge of his duties, and by taking and subscribing the usual oaths for the faithful per- formance of his duties. It shall be the duty of said inspector to report to and be subject to the control of the board of health, except in so far as any require- ment of said board may conflict with this ordinance or other ordinances of the city of Richmond. (2) The board of health shall be authorized in their discretion to employ from time to time, and for such time as they may designate, one or two assist- ants to the inspector of milk and food supplies, one of whom shall be an ana- lytical chemist, to whom said board may assign such duties as they may deem expedient, and who, when acting in the place of said inspector, shall have all of the powers and authority vested in him under this ordinance, and at all times shall have the powers and discharge the duties prescribed by regulations, to be adopted by the board of health as hereinbefore provided. (3) The salary of the inspector of milk and food supplies shall be $900 per annum, payable monthly, and the compensation to the assistants shall be at the rate of .$50 each per month, to be ascertained and certified by the board of health to the committee on health, who shall issue a warrant therefor on the treasurer. (4) That from and after 30 days from the passage of this ordinance no per- son shall, within or without the city of Richmond, maintain or keep a stable or stables or a dairy farm for the purpose of producing milk to be sold or exposed to sale within the limits of the city of Richmond, nor shall any person within the limits of the police jurisdiction of the city of Richmond, outside of the three public markets of said city, keep a room, stall, store, or other place where any meat, butter, fish, fruit, or vegetable, intended for human food, are sold or exposed to sale without first obtaining a permit so to do from the inspector of milk and food supplies of the city of Richmond. Application for said permit shall be made in writing, upon a form to be prescribed by said health ofiicer, in which application it shall be stipulated that the said inspector or other health officer of the city of Richmond may from time to time inspect such place and premises and the milk produced or food supplies exposed to sale thereat, and also that such applicant will conform to the requirements of this ordinance, and such reasonable rules and regulations as may be established by the board of health for the government of such place or places. Every person to whom such permit is granted, before he shall be entitled to carry on business, for which he desires such permit, shall pay to the auditor of the city of Richmond a fee of $2 to cover the expenses incident to the inspection of milk and other food supplies in the mode prescribed by this ordinance. Before granting such permit it shall be the duty of said inspector to make, or cause to be made, an examination of the place and premises, which are intended to be used in the maintenance of said dairy farm or stable, and of such place, stall, or store, where is proposed to sell milk, meat, butter, fish, fruit, vegetables, or other food supplies and thereafter, from time to time, inspect the same, and if found in an unsanitary condition, such permit may be refused, or if granted, may at any time be revoked or suspended, without notice, by said inspector, if, in his judgment, such dairy, dairy farm, or place is found to be in an unsanitary condition. (5) It shall not be lawful for any person, by himself or by his servant or agent, nor for any such servant or agent of any person, to sell, exchange, or deliver, or to have in his or their custody or possession, with intent to sell, exchange, or deliver, or to expose or offer for sale as pure milk, any milk from which the cream or any part thereof has been removed, or which has been watered, adulterated, or changed in any respect by the addition of water or other substance. (6) No dealer in milk, and no servant or agent of such a dealer, shall sell, exchange, or deliver, or have in his custody or possession with intent to sell, exchange, or deliver milk from which the cream, or any part thereof, has been removed, unless, in a conspicuous place above the center, upon the outside of the vessel, can, or package from or in which such milk is sold, the words " skimmed milk " are marked in distinct letters not less than 2 inches in length. (7) No person shall sell, exchange, or deliver, or have in his custody or pos- session with intent to sell, exchange, or deliver, skimmed milk containing less than 9 per cent of the milk solids exclusive of butter fats. 334 THE MILK SITUATION IN THE mSTRICT OF COLUMBIA. (8) No person sball sell, or offer for sale, or otherwise dispose of, or shall transport, or carry for the purpose of sale, or shall have in his or their custody or possession with intent to sell or offer for sale or otherwise dispose of any impure, adulterated, or unwholesome milk, and no person shall sell adulterated milk, nor shall any person sell or offer for sale or otherwise dispose of any mik which is produced in whole or in part from cows kept in a crowded or unhealthy condition or fed on food that produces, or is likely to produce, im- pure, diseased, or unwholesome milk, nor from cows fed on any substance in a state of putrefaction or rottenness, or upon any other substance of an un- wholesome nature. (9) That the addition of water or any other substance or thing is hereby declared an adulteration, and milk that is obtained from animals that are fed upon any substance in a state of putrefaction or rottenness, or upon any sub- stance of an unwholesome nature, or milk that has been exposed to or contami- nated by the emanations, discharges, or excrements from persons sick with any contagious disease by which the health or life of any person may be endan- gered, or milk from tubercular cows, is hereby declared to be impure and unwholesome. (10) That all prosecutions under this ordinance, if the milk shall be shown, upon analysis by th"^ inspector of milk and food supplies, chemist, or board of health, or by any c mist or chemists appointed or designated by the board of health to contain n our milkman does not deliver his milk in bottles it is best to have him deliver it directly to you or your servant, and you should see that it is put on ice immediately and kept cold. The practice of putting out an uncovered pitcher or other vessel for milk the night before can not be too strongly condemned. Such a pitcher or vessel, exposed to the dust and dirt of the street, will col- lect thousands of germs before the milk is put into it. Many of these may be dangerous to life and health, besides which they will certainly cause the milk to sour in a short time and become unfit for use. The purest milk received in such a vessel may become as bad in a few hours as the worst milk from a dirty farm. If you are compelled to stand out a vessel to receive your milk, provide your- self with several glass preserve jars, which should be used for this purpose only. They should be kept well washed and aired as above described. Get jars with clamp tops. Those with screw tops are hard to keep properly cleansed. Do not use the rubber ring which comes with most jars, as it is difficult to keep clean and the jar will be sufficiently tight without it. Instead of a preserve jar a bowl, covered by a plate, may be used. A pitcher can not be tightly covered on account of the projecting spout. Give your own personal attention to your milk vessels. The milkmen of Richmond state that many persons in this city have the idea that if milk is delivered to them warm this is a proof of its being fresh from the cow, and hence better. So far from this being true, only by cooling the milk as soon as it is gotten from the cow is it possible to prevent rapid decomposition of the milk in warm weather.. The regulations of the health department (which have been adopted for your benefit) require that all milk sold in Richmond shall be cooled as soon as possible after milking. While bad milk is the chief cause of bowel troubles among young infants, it is by no means the only cause. Improper feeding is another cause. Never give anything but milk to a child under 1 year, unless advised to do so by your family doctor. If your baby has any bowel trouble call in your doctor at once, so that the case may be treated before it has gone too far. Never buy milk for the baby from a grocery store. Store milk has often been kept over from the day before, and only too often without ice or in an open pitcher in a refrigerator in which meats and vegetables are also kept. It is dangerous as food for babies. By paying careful attention to the above instructions you will do much toward keeping your family well during the summer (and especially the little ones who live on milk). You will also find that your milk will keep longer and taste better. Keep this circular and read it from time to time until thoroughly familiar with its contents. If you change servants be sure to give instructions to the new ones in the care of milk in your home. 342 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. TOPEKA, KANS.

The cows must be kept clean. 2. Manure must not be permitted to collect upon the tail, sides, udder, and belly of any milch cow. STABLES. 1. Cow stables must be well lighted and ventilated. 2. Floors must be tight and well drained. 3. Manure must be removed from the stalls and gutters at least twice daily. This must not be done during milking nor within one hour prior thereto. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 349 4. Walls and ceilings must be kept clean. 5. Tlie ceilings must be so constructed that dust and dirt therefrom shall not readily fall to the floor or into the milk. 6. Stables must be whitewashed at least once a year. THE WATER SUPPLY. 1. The water used in the barn and for washing milk utensils must be free from contamination. THE MILK HOUSE. 1. A milk house must be provided, which is separated from the stable and dwelling house. 2. It must be kept clean and must not be used for any purpose except the handling of milk. THE MILKERS. 1. No person having any communicable disease, or one caring for persons having any such disease, must be allowed to handle the milk or milk utensils. 2. The hands of the milkers must be carefully washed immediately before milking. THE UTENSILS. 1. All milk utensils, including pails, cans, strainers, and dippers, must be kept thoroughly clean and must be washed and scalded after each using. THE MILK. 1. Milk from diseased cows must not be shipped. 2. The milk must not be in any way adulterated. 3. The straining of milk must be done in the milk house only. 4. All milk must be cooled to a temperature not above 55° within two hours after being drawn and kept thereafter below that. 5. The use of any preservative or coloring matter is an adulteration and its use by a producer or shipper will be a suflQcient cause for the exclusion of his product from the city of Wheeling. Recommendations. In addition to the preceding rules, the department makes the following recommendations : THE BARNYARD. 1. It should be well drained and dry and should be as much sheltered as possible from the wind and cold. 2. Manure should not be allowed to collect in the barnyard and should not be at any time in contact with the stable or milk house. THE STABLE. 1. The cow stable should have abundance of light and ventilation. The ventilation should preferably be from the top. 2. There should be at least 600 cubic feet of air space for each cow. 3. It is desirable that the place where the cows are kept be used for no > other purpose. A cow bam should not be used as a storage place for straw, hay, or other feeds, or as a wagon or tool house, as the dust and dirt which accumulates in a place of this character is liable to drop into the milk while being drawn. 4. Stable floor should be made tight and be of some nonabsorbent material. 5. Cement or brick floors are the best, as they can be more easily kept clean than wood or earth. 6. If the space over the cow is used for storage of hay, the ceiling should be made tight, to prevent chaff and dust falling through. The practice, somewhat common among farmers, of packing hay, etc., on loose poles over the cows is exceedingly bad, since it invites the collection of dust and cobwebs, and the difficulty of keeping the stable clean is increased. 350 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 7. The stable should be whitewashed at least once a month. 8. The manure gutter should be from 6 to 8 inches deep and should be kept free from manure. 9. The use of land plaster or lime upon the floors and gutters is recommended. 10. The flooring where the cows stand should be short enough so that all manure will be dropped into the gutter and not upon the floor itself. 11. The floor should be swept at least an hour before milking, in order that the dust may have a chance to settle before the milking is begun. 12. If individual drinking basins are used for the cows they should be fre- quently drained and cleaned. THE cows. 1. The cows should be kept at all times in a healthy condition and an exami- nation by a veterinary surgeon should be made twice a year. 2. The cows should be groomed daily and all collection of manure, mud, or other filth should not be allowed to remain upon their flanks, sides, udders, or bellies during milking. 3. The clipping of long hairs from the udder and right side of the cow is of assistance in preventing the collection of fllth, which may drop into the milk. 4. The hair on the tails should be cut so that the brush will be well above the ground. 5. In winter the tail may be clipped. 6. The cows should be bedded with shavings, dried leaves, straw, or some equally clean material. 7. The use of horse manure for bedding is to be condemned. 8. To prevent the cows from lying down and getting dirty between cleaning and milking, a throat latch of rope or chain should be fastened across the stanchions under the cow's neck. THE MH^KING AND MILKERS. 1. The milkers should be clean. 2. Their hands should be thoroughly washed with soap and water and care- fully dried on clean towels before milking. 3. Clean overalls and jumpers should be worn during the milking of the cows, should be used for no other purpose, and when not in use should be kept in a clean place protected from dust. 4. The hands and teats should be kept dry during milking. 5. The practice of moistening the hands with milk is to be condemned. 6. The first few streams from each teat should be rejected, as this contains more bacteria than the rest of the milk. 7. All milk drawn from the cows 30 days before and 10 days after calving should be rejected, and also all milk from diseased cows. 8. The pails in which the milk is drawn should have as small an opening at the top as can be used in milking. This renders the collection of dust less likely. 10. Dry fodder should not be fed to the cows during or just before milking, as dust therefrom will fall into the milk. THE MILK. 1. The milk should be removed to the milk house as soon as drawn and strained and cooled to the proper temperature at once. 2. A good plan is to strain the milk into cans which are standing in ice water which reaches the neck of the can. 3. The more rapidly the milk is cooled the safer it is and the longer it will keep sweet. 4. Ice should be used in cooling, as very few springs are cool enough for the purpose, 5. If aerators are used, they should stand where the air is free from dust or odor, and on no account should they be used in a stable. 6. Milk strainers should be kept exceedingly clean and scalded a second time just before using, and if cloth strainers are used, several of them should be provided, in order that they may be frequently changed during the straining of the milk.

COMMTTNICATIONS FROM ME. HERBERT P. CARTER SUBMITTING DETAILS FOR ESTABLISHMENT OF LARGE DAIRY FARM FOR SUPPLYING MILK TO THE WASHINGTON MARKET. Manor Daikt Co., Arlmgton, Va., 'Novem'ber 1, 1910. Mr. J. L. WiLLiGE. Deab Sib : I should be glad if you would look over tlie inclosed paper, wliicli is merely an outline sketch. I should also be very pleased if you could come out and see our dairy, which was only organized this year. The matter of the milk supply is simply a matter of straightforward business, I believe, which can easily be settled by competent business men. I will try to see you very soon. Yours, truly, Herbert P. Carter. consumers' milk association of the district of COLUMBIA. It is of the utmost importance to residents in the District to have a pure and abundant supply of milk. This supply can be obtained only by generous treatment of the farmers in the matter of payment, together with a demand for milk of high quality. If the farmers find that it pays to supply good milk, they will soon increase their facilities until all the demands of the District are satisfactorily met. At the present time they have not the necessary capital to submit to the tuber- culin test for their herds and to meet all the requirements of the health depart- ment. Even if they could do so, the price which the dealers are willing to pay is insuflBcient to compensate them for the outlay of capital and the labor and trouble involved. A system could easily be inaugurated of more direct dealing between the con- sumer and the farmer than obtains under the existing system, and the result would be a better article for the consumer at no higher price than he has been accustomed to pay, and far more satisfactory conditions for the farmer. It is unnecessary here to dwell on conditions which are well known in regard to the scarcity of milk and the unwillingness of farmers to have their herds tuberculin tested. It is believed that some such scheme as that which is explained below would meet all the difficulties of the situation. If the farmers can be insured against loss and a satisfactory price secured for their milk, all difficulties in the way of meeting the requirements of the health department and of the consumer would speedily be overcome. OUTLINE OF PROPOSED SCHEME FOB THE FORMATION OF A CONSUMEES' MILK ASSOCIATION. A company to be incorporated with sufficient capital to carry out the follow- ing objects : 1, The establishment of one or more stations for the bottling and delivery of milk in Washington, with all the necessary equipment. 2. The making of loans to farmers to enable them to submit their herds to the tuberculin test without delay, to replace diseased by healthy cattle, and to bring their equipment up to the standard required by the association. These loans would be secured by the cattle in the farmer's possession, or other ap- proved security, and. would be repaid by the deduction of a reasonable sum from the price paid to the farmer for every gallon of milk shipped by him. He would be under contract to ship a certain minimum to the association. An additional security for these loans would be the compensation by the Legislatures of Virginia and Maryland — if any should be voted — for cattle slaughtered after reacting to the test. Compensation is already given in the District. The financial assistance indicated in the second of the above two objects is the key to the present situation. The association can gain the good will of the farmers, give them a satisfactory return for their products, and at the same time earn handsome dividends for the stockholders. 352 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. It will be obvious that at the present time the carrying out of such a scheme will be given plenty of publicity by the papers, and that comparatively little advertising will be needed to enable the association to place all the milk that it can purchase from the farmers. Probably it will be found desirable for the association to give financial help to farmers who have good barn accommodation to spare, to enable them to increase their stock and the association's supply. By paying 30 cents a gallon for highest grade milk and 26 cents a gallon for second grade, and retailing them at 10 and 9 cents a quart, respectively, the association would make a profit of 10 cents a gallon. The above wholesale prices are much higher than dealers now pay, and 2,000 gallons a day could easily be obtained. A CONCEETE INSTANCE OF THE WAY THE ABOVE PLAN WOULD WORK. Farmer B now ships to Washington 40 gallons of milk. He has 20 cows, which are not tuberculin tested, and he has inadequate facilities for cooling the milk and cleaning his cans. He obtains, at most, 22 cents a gallon for his milk, and can not afford to have his cattle tested without compensation, or to improve his equipment. The association arranges with farmer B to have his herd tested and to improve his outfit. It advances, say, $300, for replacing reacting cows with healthy animals and for the needed improvements. Farmer B can now ship 20 gallons of milk of higher quality, and the asso- ciation can afford to pay him 30 cents a gallon. From this they can deduct 5 cents and so pay off the loan, with interest, in less than a year. The farmer will have been getting a net advance of 3 cents a gallon, and at the end of the year will have a better herd and better equipment than he had before.

Mr. J. L. WiLLiGE. Dear Sir : I have pleasure in inclosing an outline of a plan for the organiza- tion of a large dairy business. OflScials of the Dairy Division, Bureau of Agriculture, would be well able to pass on the reasonableness of my estimates. I may say that if a corporation was formed somewhat on the lines sug- gested I should be pleased, if the directors so desired, to become associated in the management and to place all my time at their disposal for a year or two and accept payment entirely according to the results achieved. I am con- fident that the plan is the most efficient and economical possible, if it can be organized with sufficient capital. Yours, very truly, Heebekt P, Oaetbb. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 353 The proposed establishment of a large dairy farm near Washington, together with a town depot for the distribution of milk, the whole to be owned and operated by a corporation financed by the people of Washington, D. C. Modern requirements in the handling of milk and modern improvements in farm machinery make a dairy farm operated on an extensive scale the only logical way of dealing with the milk question. The essential conditions for any location to be considered for the farm are : (1) Part of the farm must touch a convenient railroad line. (2) There must be an abundant supply of good water on the farm. A running stream, indeed, is essential. ADVANTAGES, EFFICIENT COOLING OF MILK, CLEANING AND STERILIZING OF ALL "UTENSILS. The small farmer can not be expected to get all the expensive apparatus which is needed for cooling milk efficiently and for cleaning and sterilizing all utensils. On the other hand, on a large farm operating its own ice plant, where 2,000 gallons of milk had to be handled, the cost per gallon for efficient cooling, etc., would be insignificant. If pasteurizing was desired, it could also be carried out economically. EFFICIENT AND ECONOMICAL SHIPPING. A refrigerator car on a private siding adjacent to the dairy building, ready to be filled with milk cans and attached to a passenger train for Washington. Contrast this with the shipping methods possible to the small farmer ! It would probably be found desirable to bottle the milk at the farm ready for delivery to the consumer. This would add to the cost of shipment, but is the most sanitary of all methods, and avoids the delay and expense of an extra handling of the milk. ECONOMY IN LABOK. With a large number of employees, labor can be much more economically and systematically directed than is possible on a small farm. Reasonable provision, too, can be made for the entertainment of the men and their families and for the education of their children. In this way the best class of labor can be attracted to the place. Besides, the men would always feel certain of their pay. This is not the case on every small farm. LABOR-SAVING DEVICES. Manure spreaders, 2-horse corn planters, and feed cutter with powerful engine are typical instances of the kind of machinery which saves a large amount of labor on a large farm, but which would be out of the question on a small place. A large farm can have a blacksmith shop of its own, which in itself means a great saving of time and money. i ECONOMY IN FARM HORSES. By going in for mule raising and using brood mares for the farm work, except for one or two strong teams for the heaviest work, it is possible to make the horses almost, if not quite, pay for their own keep. This plan could not be carried out on a small farm, but where 20 or more horses were needed for farm work it would be most remunerative. In the following estimate of capital required, the cost of buildings, etc., Is based on the actual cost of material and labor in putting up barns and dairy buildings at Arlington, Va., in the summer of 1910, according to plans furnished by the Bureau of Agriculture and thoroughly approved by the health depart- ment of the District. Allowance is made for grading and all extras. With the economies possible in work undertaken on a large scale, with ready cash, it is probable that the estimate given might be materially reduced, even if everything used was of the best quality. The average price of milk to the retail customer is placed at 9 cents per quart. Probably 10 cents would be charged for seven months and 8 cents for five months in the year. This would make the average price more than 9 cents. Oream is sold at a proportionate rate and need not be treated separately. 82444°— S. Doc. 863, 61-3 ^23 354 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. It might be profitable to undertake butter making on account of the high price which could readily be obtained for genuine buttermilk properly shipped. There is now a very large and profitable trade in artificial buttermilk, but no account is taken of this in order that the estimate of income may be well within the mark. The profits easily obtainable from hog raising are also disregarded. The amount of milk given by each cow is calculated at 2 gallons a day on an average. With such a liberal allowance as $100 for the price of each cow, this amount ought certainly to be exceeded. It is assumed that not much feed would be raised on the farm during the first year, and the daily allowance is therefore placed at 20 cents per cow. For the second year 10 cents per cow is allowed, but this amount would gradually be reduced as the farm reached a higher state of cultivation, and the profits would be correspondingly increased. For the summer months, at any rate, it is safe to assume that the estimates of 20 and 10 cents given above would be in excess of the actual cost. The estimates made for labor, feed, and depreciation give ample margin to allow of raising suflicient calves to keep up the standard of the herd. With the estimates here given a profit is shown on the investment of $500,000 of over 12 per cent in the first year, rapidly increasing to over 20 per cent. If we allowed 21 gallons of milk for each cow as a daily average — no un- reasonable estimate — the profits would be increased to at least 17 per cent for the first year and 24 per cent for the second year, gradually increasing to 28 per cent or more. Efficient management would undoubtedly increase even these profits. Capital : 1,500 acres, at $100 per acre ; $150. 000 1,000 cattle, at $100 100, 000 Barns, silos, farm and dairy buildings, fences, cottages for men employed, machinery, dairy utensils, etc 175, 000 Depot in Washington for distribution of milk, land and buildings owned by company 75, 000 500, 000 Daily expenses : Labor and management, including town depot , 2.50 Shipping and distribution, depreciation, taxes, etc 100 Feed (first year) 200 550 Estimating feed at $100 for second year, the total would be $450. Daily income : 2,000 gallons of milk, at 36 cents, $720. Daily profit : $170 in first year, $270 in second year, increasing in later years to $320 or more. Annual profit: $62,050 in first year, $98,550 in second year, $116,800 or more in later years, or 12.41 per cent, 19.71 per cent, 23.36 per cent, respectively. It is important to observe that 2,000 gallons is only a small part of the milk consumed in Washington; that the milk shipped by the corporation would be of the highest quality and would meet with a ready sale, probably even at a higher price than that here estimated. If the stock of the company were divided among 8,000 people, each of whom took 1 quart of milk daily, the whole output would be disposed of. By accepting subscriptions for $10 or $20 of stock a large number of cus- tomers would immediately be secured. Stockholders would of course have the first privilege of purchasing milk from the company, and so help to earn their own dividends. It would seem that there should be very little difficulty about securing the necessary capital if the directors of the company are men who would command the unquestioning confidence of the people of Washington.

WiLLiGK Deae Sir : I inclose some more matter in regard to our dairy-farm scheme, which will explain itself. I hope you will agree with me that this thing must go through somehow. Yours, very truly, Herbert P. Carter. If I can get any further information for you, or be of any use to you iu any way, please consider me at your service. I am not particularly busy just now. Arlington, Va., Novem'ber 4, 1910. While the proposed scheme for a large dairy farm under the management of a Washington corporation should be considered primarily on its merits as a dairy business, there are other sides to the question which should be kept in view from the first. If over a thousand acres are to be acquired within easy reach of the city of Washington, it is important to have in view the possible developments from a real estate point of view. A well-organized dairy business should make it possible to own a large tract of land, earn enough to pay taxes and good interest on capital from the very first, and at the same time pave the way for important developments in real estate business. All property within 30 miles of Washington is likely to have a remarkable increase in value within the next few years, but probably the most promising part of the surrounding country, both for present purposes in the dairy busi- ness and for ultimate purposes as suburban real estate, is the Virginia side of the Potomac between Alexandria and Mount Vernon. The communications are already good, with the Mount Vernon electric line, the Washington Southern — Accotink, Franconia, etc. — and last, but perhaps most important of all, the Potomac. A company which owned land on the Potomac, with a good site for a wharf, and touching the Mount Vernon Electric Railroad, and also property on the Washington Southern having good road communication with its property on the Potomac, would be in a remarkably favorable position for awaiting, and to a great extent controlling, future developments. . No more satisfactory location for a dairy business at the present time could well be imagined. A wharf on the Potomac would probably provide the most economical and satisfactory way of conveying milk to Washington. A kind of refrigerator barge and a suitable tug would not be very expensive, and by this means the morning's milk could easily be brought to town, bottled and ready for the customer, in ample time for the afternoon delivery. Similarly the afternoon milk could easily be brought to town in time for the early morning delivery. The service, in fact, would be as prompt as the circumstances could require. It would be most convenient to be independent of any railway line with its fixed schedules; the tug could start off whenever the necessities of the business required, and the cost of the service would be insignificant. If the tug broke down, another could be chartered at short notice. Weight and space being of relatively small account, the chief objection to bottling the milk at the farm and bringing it to town ready to be put on the delivery wagon would be removed. The wharf would be useful iu other ways. Manure and also slop for hogs and chickens could be hauled from town by this method at small expense and prove a most satisfactory source of revenue on a well-managed farm. To most farmers the cost of hauling such stuff as this is prohibitive, though the value of the stuff itself may be judged from the fact that many farmers do find it profitable to haul it several miles from the city by 4-horse wagons. Another great economy would be effected by using this wharf to bring the large amount of lumber, cement, etc., which would be needed for building opera- tions. In fact, when buying lumber on such a large scale, it might be possible to begin a very satisfactory lumber business in Washington. There would be an abundance of storage room, the tug could convey lumber to Washington in large quantities at short notice, and there would be horses in town to deliver lumber in between milk deliveries. A trade in vegetables, fruit, poultry, eggs, and all farm produce would naturally form part of the trade when the farm 356 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. got Into proper working order. It could hardly fail to be profitable with such cheap and excellent transportation at hand. As to the real estate development, it would only be necessary at first to devote a little attention to the laying out of suitable roads, planting trees, etc. Now and then a desirable tenant would be found who would put up a good house somewhere on the place. One would help others, and in course of time it might be necessary for the dairy farm to move a little farther into the coun- try. Then the process could begin over again. The strength of the plan lies in the fact that the company could afford to wait. Herbert P. Carter. P. S. — With regard to the particular merits of the country indicated above for real estate — apart from the obvious value of Mount Vernon and the present means of communication — it should be recalled that Congress has already appropriated $10,000 for the survey of Mount Vernon Avenue, and that Vir- ginia has already voted that its claim on the United States Government of $200,000, when recovered, should be devoted to the construction of this road. It would seem certain in any case that the making of a splendid road between Washington and Mount Vernon is only a question of time. The Daughters of the American Revolution and other Influential bodies are interesting themselves in the scheme. Manor Dairy Co., Arlington, Va., November 7, 1910. J. L. WiLLiGE, Esq. Dear Sir : Miss Hurn was with us yesterday and told me that you were going into the question of modified milk. There is no reason why modified milk should not form part of the trade on our proposed large dairy. The formulas could be made up and bottled at the farm and delivered from door to door with the other milk. In this way the babies would get the morning milk in the afternoon and the afternoon milk in the morning — as eflicient a service as could be organized. By bottling at the farm and delivering in the usual course of business, the price could be made as low as that charged by the Straus Labo- ratories now, yield a reasonable profit, and give the parents the advantage of delivery to their homes. The only possible objection that Miss Hurn saw was that of breakage in shipment. This, of course, is easily overcome by proper packing. I think you know that we have shipped the milk for the Straus Laboratories since they opened last spring. I am, yours, truly, Herbert P. Carteb. Arlington, Va., November 7, 1910, J. L. WiLLiGE, Esq. Dear Sir : I saw Miss Hurn to-day, after giving you my letter on the subject of modified milk, and she was emphatic in expressing the opinion that it would be impossible to sell the various formulas at the price charged by the Straus Laboratories and make any profit by it. I have never dealt in modified milk myself, so do not claim the same authority for my figures that I would in other branches of the trade, where I have been able to test them by actual experience. I will, however, give you the figures on which I based my conclusion, only hoping that I am not troubling you with too many details and too much of my own opinion. One thing, however, is certain. Modified milk could be handled more eco- nomically by a concern which produced and delivered a large amount of ordi- nary milk than by a concern which dealt in modified milk exclusively. Some such plan as that which I have outlined will provide the most eflScient and economical way of dealing with modified milk. Putting aside all considerations of charity, it might be good business to sell modified milk at a very small profit in order to help other branches of the trade. But it is my emphatic opinion that such a price ought to be placed on modified milk as will allow a small profit to the dealer and place the trade on a business basis. There are many families who, while anxious to get milk for their babies at as reasonable a price as possible, would prefer not to be in receipt of charity in any form, considering it injurious to their self-respect. Moreover, the milk ought certainly to be delivered to their doors. Time is money, even to the poor, THE MILK SITUATION IN THE DISTEICT OP COLUMBIA. 357 and it would pay them to give a few cents more for their milk instead of having to walk some distance to get it. There can, of course, be no charity more deserving of support than that of providing proper nourishment for babies. By all means let there be a fund, supported either by public or private benevolence, to enable the poor to get the milk which their children need. But a truer charity, one deeper and more far- reaching in its effects, would be to provide milk for the young children of the self-respecting wage-earning class at such a price as would at least pay for the cost of production, but still make no exorbitant demands on people of limited means. Modified milk delivered to the door of the consumer at cost price and a fund to help the really needy to buy it; this I believe to be the ideal at which we should aim. To take a definite instance of modified milk for purposes of estimating the cost: Formula (Nathan Straus Laboratories) for infants from second to sixth month. Ounces.

This allowance would naturally not be sufficient where a special building had to be rented, special managers engaged, a large boiler kept specially in operation by a licensed engineer, and a large amount of ice bought, to say nothing of pay- ing a high price for milk and providing for a special delivery to substations. But where there was already an abundance of steam and ice, and all the oper- ations were under the same management as the rest of the trade, there would be great economy, and it is safe to say that the price of modified milk, delivered to the door of the customer, would not be very greatly in excess of that now charged by the Nathan Straus Laboratories. I remain, yours, very truly, Heebeet P. Caeteb. APPENDIX I. TESTIMONY ADDUCED AT HEARING BEFORE DISTRICT COMMISSIONERS, OCTOBER 20, 1910. Db. Melvin's Testimony. Dr. Melvin testified as follows : For several years the Department of Agriculture has been endeavoring to ascertain the approximate percentage of the tuberculosis that exists among cattle in the various sections of the United States, and we had previously made a great many tests in and about Washington and other sections. In doing that it was determined that tuberculosis did exist to considerable extent in the District. The test showed that 1,701 cattle were tested with tuber- culin. Of that number 319 responded, and there were two held as suspects for subsequent testing at a later date, usually from two to three naonths. The total reimbursement to owners was $13,855.10, for 305 cases. The average loss to owners was 27.65 per cent of the value of the destroyed stock. 358 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. Otber tests have been made in Virginia and Maryland. In Virginia, from July 1, 1909, to June 30, 1910, there were tested 899 cattle, of which 162 reacted, 39 were held as suspicious, and the per cent of reacters and suspects was 18.27. In Maryland, in the same time, 289 were tested. Forty-eight reacted, 6 were suspected, and the percentage of reacters and suspects was 15.74. During that same period of time there were retested in Virginia and Mary- land animals previously tested. In Virginia 923 passed, 39 reacted, 4 were held as suspects, making a percentage on the retest of 4.45 per cent, a reduction from 18.27 from the first test. In Maryland, on the retest, 301 passed, 5 reacted, 3 were suspects, making a percentage of reacters and suspects of 2.58, a reduction from 15.74. CONDITIONS IN DISTRICT. In the District we have retested and found free from tuberculosis 423 ; we have found 31 reacters and 1 suspect, or a percentage of reacters and suspects of 7.03. We have demonstrated beyond any question the feasibility of eliminating tuberculosis by three or four tests of this sort. In the tests that we made here in the District tuberculosis was demonstrated in cattle that reacted in something over 98 per cent of the cases. We found in 126 cattle in and near the city of Washington that tuberculosis was demonstrated in 99.21 per cent of the cases which reacted. In a table I made as a result of the tuberculin testing of cattle by State and Federal officers with tuberculin prepared by the Bureau of Animal Industry, we found that between 1893 and 1908, there were tested 400,008 cattle. The number reacting was 37,000. These were in all parts of the United States, and were a per- centage of 9.25 of all cattle tested. The number slaughtered under inspection was 24,784 ; the number of these found tuberculous upon post mortem was 24,387, or 98.39 per cent. Db. Mohles's Statement. Dr. Mohler's testimony was as follows: Introductory to my statement concerning the tuberculin test I would present extracts from bulletins on bovine tuberculosis in Virginia and Maryland, States which now supply the greatest amount of milk to the citizens of the District of Columbia. I refer first to the statement of Dr. Buckley, of the Maryland Agricultural Experiment Station. He says: " Usually the discovery of an agent which, when properly used by compe- tent persons, enables them to detect positively the existence of a condition that is not revealed by any other means is hailed as a wonderful triumph. If the opposition to the use of tuberculin as a diagnostic agent came from those, only, who were ignorant of its properties and who could not inform themselves of its virtues it would be wholly excusable. The practice of using tuberculin, how- ever, has been and is now condemned by some who know its value and who have been in a position to observe its reliability." On the other side of our line, in Virginia, I would like to take a sentence from the book of Dr. Nelson Mayo. He is the veterinary in charge of the agricultural station at Blacksburg, Va. In his book, on page 382, he states as follows : " The most accurate means of detecting tuberculosis in cattle is by injecting a small amount of tuberculin beneath the skin. When prepared for use, tuberculin contains no germs of tuberculosis and is incapable of producing any disease." TUEEKCULIN HARMLESS. During the last 15 years statistics with reference to bovine tuberculosis show that over 98 per cent of the animals tested show adhesions at the post-mortem. Tuberculin is the most accurate diagnostic agent known when it is in the hands of competent men. As to the possibility of defeating the test, the farmer might infect his cattle before the inspector comes around. The best means to prevent this would be for the inspector to stay with the herd about 24 hours. An attempt to defeat the tuberculin test should be considered as any other fraud and guarded against by precautions. I would like to speak of the Report of the International Commission on the Control of Bovine Tuberculosis, of which I was a member, and to leave a copy of the report with you and call your attention to this resolution in it: . THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 359 " That tuberculin, properly used, is an accurate and reliable diagnostic agent for the detection of active tuberculosis. " That tuberculin may not produce a reaction under the following conditions : "(a) When the disease is in a period of incubation. "(&) When the progress of the disease is arrested. "(c) When the disease is extensively generalized. " The last condition is relatively rare and may usually be detected by physical examination." Thirty-three cities in the United States now require that herds which supply their milk be tuberculin tested. Error in the application of the tuberculin test has never been found to be greater than 3 per cent. Views of Dk. Scheoedeb. Dr. Schroeder testified as follows : The efiiciency of the tuberculin test has been well demonstrated and it is hardly necessary to say anything more on the subject. When we consider that the tuberculin test gives an accurate diagnosis of tuberculosis in cattle, in between 98 and 99 per cent of the cases, we must recognize that we have a more reliable diagnostic method in this disease than in any other known dis- ease. I have given the tuberculin test a great deal of attention throughout many years. I have given animals as high as 1,000 doses of tuberculin at a single time and in healthy animals it produces no injury. We use at the experiment station a great many animals in various forms of experiments. Before using them we inject tuberculin to assure ourselves they avB perfectly well. We have injected large quantities of tuberculin into well animals and they have shown no symptoms of trouble, and after being killed have been found perfectly well. At the experiment station I had a number of animals from District herds, apparently in the best of health, so far as physical examination was concerned. We submitted them to the tuberculin test and 40 per cent, apparently healthy, reacted. HUMAN AND BOVINE TUBERCULOSIS. Relative to human and bovine tuberculosis, from the researches of the German and British investigating commissions, and independent investigators, we know that bovine tubercle bacilli are fairly common in human beings. There was one interesting feature brought out at the last International Con- gress on Tuberculosis. It was an investigation by W. H. Park, of the New York research laboratory. Twenty-six per cent of the children under 5 years ex- amined by him and found to have tuberculosis were afCected by bovine tubercle bacilli. I do not believe it is necessary to add anything to this. We have the efficiency of the tuberculin test thoroughly demonstrated, and the frequent occurrence of bovine tuberculosis among children alone shows we must eliminate those cattle or do something to the milk to prevent it doing injury. That something is pasteurization. The tuberculin test should be required of all dairy herds. Where it is not required, all milk should be pasteurized before it is used. This should apply not only to milk and cream used in their raw state, but to all milk and cream contained in ice cream, buttermilk, butter, and cheese. I have demonstrated that 40 per cent of apparently healthy cows that have tuberculosis in its early stages pass tubercle bacilli in the feces. Unquestion- ably, much of the tubercle bacilli in milk enters it in this way. Tuberculous cows whose milk does not show the presence of tubercle bacilli pass the bacilli in the feces, and for this reason their product can not be safely used unless it is pasteurized. This shows the menace in the apparently healthy cow that has not been tuberculin tested. Dr. Anderson's recital of his observations concerning the milk supply of Washington follows : Just prior to October, 1907, 1,147 cows of the District of Columbia were given the tuberculin test, and 214, or 18.6 per cent, responded. About the same time 1,059 cows from 51 herds of Virginia, Maryland, and the District, supply- ing milk to Washington, were tested ; of this number, 160, or 15.1 per cent, reacted. These figures do not give a fair idea of the prevalence of tuberculosis in the herds supplying milk to Washington, as only the owners of those herds B60 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. who had reason to think their herds were free from tuberculosis permitted the test to be made. I took, in the fall and winter of 1908, 272 samples of the market milk of Washington and injected them into guinea pigs. Of the 272 animals 49, or 18 per cent, died within 3 weeks of other causes before tuberculosis could have developed. I wish to direct attention, also, to the fact that the milk from some of the dairies, therefore, killed actually a high percentage of all the ani- mals to which milk was given, showing the milk contained other bacteria. Of the 223 samples that remained for study 15, or 6.72 per cent, contained sufficient tubercle bacilli to cause typical tuberculosis in the inoculated animals. Of the samples of milk from 104 dairies 2 were lost by acute death of the animals, leaving 102; the milk from 11 of these 102 dairies contained tubercle bacilli. This gave a percentage of 10.7 of the dairies examined showing tubercle bacilli in the milk supplied their customers. ELEVEN PER CENT AFFECTED. These results, showing that approximately 11 per cent of the dairies whose milk was examined contained tubercle bacilli virulent for guinea pigs, do not, however, give a fair idea of the frequency of the presence of tubercle bacilli in the market milk of the city of Washington. When two animals were inoculated with the same sample both did not always develop tuberculosis. This would indicate that the bacilli were so few in the amount inoculated that one of the animals, by being a little more resistant, was able to overcome the infection. The amount inoculated, less than 2 cubic centimeters of milk, is a very small portion of a pint bottle. The creamy layer was not inoculated, and other workers have shown that tubercle bacilli are more frequent in this than in the bottom milk. It is very probable that if more animals had been inoculated with the same sample and both cream and sediment used, the percentage of positive results woudl have been much higher. The results, however, as they are found are sufficiently high to emphasize the necessity for the enactment and rigorous enforcement of a law requiring that all cows supplying milk to the District be tuberculin tested and freed from tuberculosis. This test, which is now universally recognized as a means of determining whether an animal has tuberculosis, should be made by a com- petent veterinarian, and those animals that respond should be disposed of in some way so that their milk may no longer be a source of danger to the com- munity. I have compiled the statistics of investigators who have collected in all 1,734 samples of milk in recent years. Of these samples 11.3 have been found to contain tubercle bacilli. Mr. Herbert P. Carter. I speak from the producers' point of view. There are two questions brought up which I have nothing to do with. One is the personal controversy between the officials of the health department and the dealers in milk here, and the second is the matter of the scientific controversy as to the merits of pasteurization. I am not entitled to any opinion on its merits, but I can be convinced by an examination of the evidence, which shows that the tuberculin test is sufficient in a large number of cases. I can say for my part I am not bothered about the order for the tuberculin test, as my herd has been tuberculin tested from the first, and I know about the 'cattle that have been slaughtered from my herd after reacting, and I should have been sorry to serve milk from them. It certainly served to weed out the bad cattle from my herd, cattle that I would be sorry to keep in. It seems to me this is a matter which neither the producers nor dealers have a right to discuss. We can not pretend to be scientists. If the scientific opinion requires such tests, it is the business of the producer to obey them as well as he can. The whole question is a matter of compensation. It is a matter of dollars and cents. There may be many people who have worked hard for many years to produce a herd of, say, 20 cattle, honest, hard-working, laboring men. They have not had any tuberculin tests applied, and they have not done anything against the law or against their conscience. The profit of the herd of 20 cattle is not anything extraordinary. You must consider in this connection that the producer of milk has an exceptionally hard life. It is a case of woi-king seven days in the week and not six. He should therefore receive additional compensation. THE MILK SiTUATtOK IK THE DISTBICT OF COLUMBIA, S61 Suppose he has a herd of 20 calves. He may rely on getting 2 gallons of milk from each calf on an average. If he gets 40 gallons a day and in the winter gets 22 cents, which is a pretty good price, that represents $8.80 a day from that herd of 20 calves. If we calculate the cost of feeding each one at 20 cents in winter we would deduct $4 from the $8.80, leaving the producer with a net income of $4.80 a day. He would have to pay his rent and for sending the milk to town, and from time to time his cows go dry, so his income is really inadequate. If farmers are to be required to meet all kinds of expensive requirements, it will add more expense. I think, personally, it is desirable that the cattle should be housed in thoroughly sanitary stables, but that means an investment of considerable capital, and if the tuberculin test is applied it means also a certain amount to be written off at a loss; but it has a more serious bearing if it is applied suddenly and without warrant or compensation. A man may have his whole fortune staked on this herd, and if he is to have the test applied, having done nothing against the law, it may mean that half of his cattle will be condemned ; and it is not infrequent for half the cattle to go under the test, especially if housed under insanitary conditions. He faces a loss of half his herd with only what he can get from the butcher for the meat; maybe in some cases he will lose all. At any rate it means a serious loss to the producer. I don't think the producers or dealers should attempt to down the laws as to what test should be applied, but if we submit to certain tests we have a right to ask for proper compensation. It is not for us to determine whether the test is by the Government of Maryland or Virginia or the District, but it is fair that the people of the District should pay up a proper amount if they require it. If there is increased protection to the puWic, the producers must be properly com- pensated for it. If they have proper compensation, I don't think there is any objection to submitting to the test. Then if the test is continually applied after proper compensation is given, all that is required is that sufficient price is paid for the milk. A higher price will have to be paid by the consumer for a more valuable article. I therefore ask the commissioners to use their influence to obtain proper compensation for the producer of milk. If this business is made productive enough to the people in the neighborhood, there will be enough milk coming into Washington. Under present conditions it is not to be expected that any of the poor class of producers can attempt to meet the requirements in the District, but if they get compensation for the cattle condemned and get better prices they will in- crease the facilities, and there will be no friction between the health depart- ment and themselves in meeting the requirements. APPENDIX J. COMMUNICATION" FROM A. S. TRUNDLE, REPRESENTING THE DAIRYMEN's ASSOCIATION OF THE DISTRICT OF COLUMBIA, MARYLAND, AND VIRGINIA. The Dairymen's Association of the District of Colitmbia, Maryland, and Virginia, Washington, D. C, November 20, 1910. Mr. J. Louis Willige, Chairman. Dear Sir : In compliance with your suggestion, under date of November 18, would say the complaints lodged by me in behalf of the Dairymen's Association of the District of Columbia, Maryland, and Virginia were, first, that the health officer, in violation of law, has refused to issue permits to ship milk into the District of Columbia, although all sanitary requirements had been complied with ; second, that the health officer had in the absence of any possible author- ity cited members of this association to appear before him and show cause why milk claimed to have been sold by them contained so-called excessive numbers of bacteria (this in the absence of law or regulations to name any specific number) and had threatened to have them summoned in court; third, that in the opinion of this association the health officer had mislead the District of Columbia Commissioners, by making to them (this determined by their reply 362 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. to our complaints) statements tbat were misleading. To sustain these charges we offer the applications of producers for permits filed with the health depart- ment and not granted, copies of summons to dealers and to producers to appear as cited, and copies of letters and answers thereto as indicated in charge third, to all of which proof is to be found in the health office records, if such records are kept and filed as is the general custom and if such records have not been tampered with. A further claim, together with a request to the chamber of commerce, for investigation was to the effect that if such policies as indi- cated in charges first and second and the requirements of a compulsory tuber- culin test were to be carried out, such policies would drive producers and dealers out of business or would result in shipments to other markets, thus diverting money to other cities that should naturally come to Washington. A further claim that I wish personally to file is, that, in my opinion, if the health officer had a right to issue an order for the compulsory tuberculin test (which order was issued to take effect on November 3, 1910, and since rescinded), he has that right now and has had such right for 15 years or since the milk law of 1895. That if, as he claims, recent researches and advanced knowledge has convinced him that milk from cows not having stood the tuberculin test is dangerous to public health, he is not only violating the laws of Congress but his sworn obligations, and further, if, as I understand, he claims to have knowledge that death has ensued as a result from consumption of milk from cows not having undergone the tuberculin test, he stands to-day a confessed party to the cause of probable death and therefore a criminal in the eyes of the law. Please find inclosed list of members as asked for. Very truly, yours, A. S. Trundle, Chairman. P. S. I can but feel that we have not had ample opportunity to present to your committee many facts without a knowledge of which it is absolutely impossible for anyone to arrive at conclusions which would insure full justice to the cause and business we represent as concerns ourselves or the general public. A. S. T. APPENDIX K. COMMUNICATIONS FROM HEALTH OFFICER, DISTRICT OF COLUMBIA, DATED NOVEMBER 14 AND 23 AND DECEMBER 20, 1910. Commissioners of the District of Columbia, Health Department, Washington, November 14, 1910. Mr. J. Louis Willige, Chairman Committee on Milk Supply, Chamber of Commerce, Washington, D. 0. Dear Mr. Willige : As your committee has decided, I understand, to give no more public hearings, the following comments are submitted for consideration : As to the accuracy of the records of births and deaths in this department. — The allegation made by Mr. Trundle at the first hearing, and the correctness of which was denied by the health officer, was to the effect that the records of the department showed that more infants died than were born. Evidence that could not be disputed having been offered to show that the statement was incorrect, Mr. Trundle shifted his ground so as to make it appear that he had said that more people died than were born. It is not alleged that this shifting of ground was intentional, but possibly Mr. Trundle's original statement was unintentionally inaccurate. The fact that I have quoted accurately what he actually said is, I think, certain, since I recall the statement that one member of the committee remarked that it was hardly possible that a sufficient number of babies would be imported into the District during the year to make up the deficiency represented by the alleged excess of births over deaths. With respect to the Trundle- Childs difficulty. — The committee has not heard Dr. Childs's version of the affair, and in view of the fact that Trundle was found guilty while Dr. Childs was not, is sufficient evidence to show who was the culpable party. Dr. Childs is a very polite respectable colored physician THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 363 In this city, where he is now and for years has been practicing his profession. As there was no evidence whatsoever, beyond that of the aggrieved party", to show that Childs was in any way at fault in the matter, the health officer declined to detail another inspector to examine Trundle's place of business. To detail an inspector to inspect Trundle's place of business, out of the regular course of the department's work, would necessitate the making of similar details to every other dairyman who desired it, particularly for those who did not threaten inspectors with ice picks, but made the request in a proper way, and to do this would have disorganized the inspection force. Mr. Trundle's reference to the prosecution of a Mr. Estes, unsuccessfully, by Inspector Childs is unfortunate for Mr. Trundle's argument. Inspector Childs prosecuted Mr. Estes because Mr. Estes was maintaining a dairy without a license ; he was selling much milk and cream, and some butter, eggs, and cheese. A prosecution was instituted by Inspector Childs on direct orders from the health officer. And the defense was to the effect that the sale of milk and cream was a mere incident to some other business. Mr. Estes was acquitted, but subsequently, and while continuing the very same business, applied for and was given a permit to maintain a dairy. In so far as relates to the alleged delay in prosecuting Mr. Trundle for the sale of loto-grade cream. — The case referred to was promptly referred by the health department to the office of the corporation counsel for prosecution. Such delay as occurred occurred in that office and in the police court and not in the health department. The reason for the delay is therefore unknown to the health department, but such delay could probably have been avoided by Mr. Trundle had he demanded of the court prompt trial. Acquittal was presumably brought about in large part by the length of time that had elapsed between the collection of the sample and the prosecution, thus weakening the force of the evidence. , Respectfully, Wm. C. Woodwaed, M. D., Health Officer. commissioneks of the distkiot of columbia, Health Department, Washington, November 23, 1910. Mr. J. Louis Willige, Chairman, etc.. Chamber of Commerce, Twelfth and F Streets NW., Washington, D. C. Dear Me. Willige : Until the receipt of your letter of the ISth instant I had presumed that the inquiry sheets recently received from your committee were the same as had been sent out by the committee generally, and that the desired information had been given in the hearings. I readily see now, how- ever, that the inquiries recently received call for information that was not given at that time. The accompanying statement furnishes, I believe, the information which you wish, so far as it is possible for me to furnish it. If, however, there is any further information that you desire, please do not hesitate to call on me. Yours, very truly, . Wm. C. Woodward, M. D., Health Officer.

What amount of milk, in your opinion, is daily supplied to the District of Columbia ? Amount of milk per day sold in the District of Columbia, 19,000 gallons. 5. Should the retail price of milk sold in the District be increased, and to what price? Answer. It costs more to produce milk now than it did 10 years ago ; and if the price then paid was a fair one, the price now should be increased. A fair re- tail price for milk, however, can be determined only after information is at hand relative to the cost of production and distribution under intelligent economical businesslike management in this particular section of the country, and so far as I know no figures are available to show such cost. 6. Would this price, in your judgment, be prohibitive to the poorer classes to any extent whatsoever? Answer. This question is in part answered by the answer to question 5. I may add, however, that I know of no evidence to show that wholesome milk can not be sold at a price within the reach of what may be termed in a general way "the poorer classes." The burden of furnishing evidence to show that a fair price for milk would be prohibitive to such classes rests upon those who allege the fact ; but while there may have been allegations as to the occurrence of a prohibitive price, there have been no reliable figures to show that such a price would be necessary. It must be borne in mind, of course, that the adoption of more economical methods with respect to production and distribution will tend to offset increased prices otherwise necessary. 7. In your judgment, is the farmer receiving his proper share of the money derived from the production and sale of milk? Answer. Probably, I think, the farmer is not receiving his proper share of the retail price of milk, but, so far as I know, no farmer in this vicinity has ever produced any figures to show that that is the case. Until evidence to the con- THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 365 trary is shown it may clearly be presumed as long as farmers continue to pro- duce and sell milk that they are finding it profitable to do so. 8. In your opinion, is a uniform standard of wholesale and retail prices of milk practicable? Answer. I do not believe that a uniform standard of wholesale and retail prices of milk is desirable, but I do not understand just what is meant by the word " practicable " as used in this connection. I doubt very much whether the farmers in this vicinity are sufiiciently well organized to fix a uniform standard for the wholesale price of milk. The retail milk dealer, however, does appar- ently fix a uniform standard for the retail price of ordinary milk, and I think he comes very close to fixing the price that the farmer gets. 9. Are the existing freight and express charges for transporting milk reason- able, in your judgment? Answer. I am hardly qualified to answer this question. 10. State whether, in your judgment, the requirements of the health depart- ment, including the proposed tuberculin test, can be observed by the producers without increasing the wholesale and retail price of milk in Washington. Answer. The elimination of diseased cows from the dairy herds that would result from the application of the tuberculin test and the necessity for purchas- ing sound cows to replace the cattle thus eliminated would doubtless for a while justly result in an increase in the cost of milk, although it should result in no substantial increase. Only a single item in the cost of milk production would be increased by the application of the tuberculin test ; that is, the cost of the cattle. It costs no more to feed, house, and care for a well cow than it does to care for a sick one, and in the long run the well cow may be expected to have a longer productive commercial life than one that is diseased. Ultimately, as the number of tuberculous cows in the dairy country is reduced to a minimum, the cost of milk should return to substantially what it is at present, supposing, of course, that in the meantime events do not show that the present selling price of milk is, because of other factors, too low. 11. To what extent is compulsory pasteurization, in your opinion, practicable, and is such action under consideration by the health department? Answer. With proper restrictions as to the installation of apparatus and as to the keeping of records, there would seem to be no reason why compulsory pasteurization should not be practicable. The fact that regulations directed to this end might in some cases be evaded, notwithstanding a proper system of inspection, is no reason why such regulation should not be made and enforced as far as practicable. Laws against murder, embezzlement, housebreaking, and all other kinds of crimes and misdemeanors are very commonly evaded, not- withstanding a well-organized system of police protection, but that has never been set forth as a reason why such laws should not be kept on the statute books. The health department has for some time had under consideration the advisability of the compulsory pasteurization of all milk coming from cows not tuberculin tested and believes that with respect to that part of the milk supply pasteurization should be enforced. 12. Would compulsory pasteurization, in your opinion, have any effect in reducing the amount of milk daily supplied to the District, provided the retail cost of milk (and consequently the price received by the farmer) be increased, and to what extent? Answer. I can conceive of no reason why compulsory pasteurization should reduce the amount of milk daily supplied to the district. 13. What effect, in your judgment, would the enforcement of the tuberculin test have on the wholesale and retail prices of milk supplied to the District of Columbia in summer and in winter? Answer. This question seems to have been answered in answering question 10. The enforcement of the tuberculin test would not increase the price of land, the price of foodstuffs, the price of stable accommodations, the price of labor, the cost of transportation, or the cost of distribution. It would increase for a while a single item, to wit, the cost of cattle. For purposes of illustration, assume that a farmer has a herd of 100 cattle, worth $75 each, making the total value of his cattle $7,500. Interest on this capital at 5 per cent per annum is equivalent to $375. Assume now that the tuberculin test is applied, 20 per cent of the herd react and are killed, and 20 new cows are introduced, tuberculin tested, costing $100 apiece, or 33J per cent more than the value of the original herd before testing. If we disregard the increased value of the herd that has stood the test that arises out of the fact that it has done so, the value of the herd will then be as 366 THE MILK SITUATION IN THE DISTEICT OF COLUMBIA. follows: 80 cattle at $75 each, equivalent to $6,000; 20 cattle at $100 each, equivalent to $2,000; total value of herd, $8,000. The interest on this capital at 5 per cent per annum is equivalent to $400. Between the interest in the capital invested on the untested herd and the interest on the capital invested in the tested herd the difference amounts, therefore, to but $25 per annijm. This amount is distributed over the entire output of a herd of 100 cows for 12 months. It represents the increased cost to the producer of producing milk from tuber- culin-tested cattle. This amount would probably be materially reduced if not altogether eliminated by the increased period of usefulness of the tuberculosis- free cattle as compared with those infected with the disease otherwise in the herd. Viewing the matter in the light most favorable to the producer, the increased cost of producing milk from tuberculin-tested cows should not amount to more than a small fraction of a cent per gallon. Taking the herd of 100 cows, untested, worth $75 per cow, the gross value of the herd would be $7,500. Kill 20 per cent of these cows on account of tuberculosis, without remuneration of any kind to the farmer, and appraise the remaining 80 animals as still worth as much as the entire herd — $7,500. Replace the 20 animals that have been destroyed by 20 tuberculin-tested cows costing $100 per cow, or $2,000. The value of the 100 tuberculin-tested cows would then be $9,500. Five per cent on this invest- ment would amount to $475 per annum, or just $100 per annum more than the Interest charged on the untested herd. If then we presume that the average production for each animal in the entire herd is but IJ gallons per day, the pro- duction of the herd for the entire year will be 36,500 gallons, and the increased cost per gallon, representing the interest charge on the increased cost of the herd, would amount to one-fifth of 1 per cent Of course, if a larger percentage of the herd reacted, the net increase in the cost of production would be increased, but it does not appear likely that there will be any material increase. In view of the experience with respect to the testing of cattle in the District, however, it would appear that the figure taken for condemnations — 20 per cent — was extremely liberal. 14. Would the tuberculin test, as a matter of practice, require to be applied on the farm, or would it be practicable to establish testing laboratories within convenient reach of most farms supplying milk to the District of Columbia? Answer. As a matter of practice, the tuberculin test would ordinarily have to be applied on the farm. Some cattle might be tested in the hands of dealers, and possibly quarantine or testing stations might be established to economize with respect to the application of the test. 15. Would the enforcement of the tuberculin test, in your judgment, create a milk famine in the District of Columbia? Answer. If the test could be applied within a day or a week, and were so applied, a milk famine would undoubtedly result. If the application of the tests in the first instance were spread over a reasonable length of time, no famine would result. Under ordinary conditions, the routine application of the test would not diminish the milk supply. 16.

THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 367 17. To what extent, in your judgment, is the decrease in mortality due to the improvement of the milk supply? Answer. It is impossible to estimate the extent to which the decrease in the mortality of this District is due to the improvement of the milk supply. The fact that the decrease in infant mortality has been greater than the decrease in the mortality of the population as a whole, and the fact that there has been a very marked decrease in the infant mortality from diarrheal diseases, the decrease in the infant mortality beginning almost coincidently with the enforcement of the milk law of 1895, suggests very strongly the existence of a causal relation. The extent of that causal relation, however, as stated above, is impossible to determine. There have, of course, been many other factors at work tending toward the reduction of infant mortality. It should be noted in studying the figures given in the preceding answer that the decrease in the number of deaths of children under 1 year of age from all causes and the decrease in the number of deaths of children 2 years of age from diarrheal dis- eases have occurred, notwithstanding a general increase in the population. 18. Can you suggest any additional requirements for the betterment of the District's milk supply, and the safeguarding of public health? Answer. All milk should be tuberculin tested or else pasteurized. All milk should be properly cooled and kept cool. Arrangements should be made for the instruction of mothers in caring for their infants, and this can in no other way be done so well as in connection with the free distribution of proper milk to per- sons unable to pay for it and the distribution of milk at reduced prices to persons who are unable to pay the ordinary market price for a milk of proper quality. There are, of course, many other suggestions that might be made with respect to the improvement of the health of the District, but these seem to be those most directly connected with the subject now under consideration. 19. Have inspectors been cautioned to exercise patience and tact in the dis- charge of their duties? Answer. Inspectors have been told repeatedly that it is desired that they act primarily as instructors and advisers to persons producing and selling milk, dealing with those with whom they come in contact rather as persons who desire to do right and who are to be helped along than as persons who are un- willing to do right and have to be driven along. Inspectors have been directed to use compulsion only when compulsion was necessary. 20. Have there been many complaints filed of improper action on the part of inspectors in the performance of their duty? Answer. During the fiscal year ended June 30, 1910, there were approximately 10 complaints filed against inspectors in the dairy-farm and milk-inspection service, numbering in all 10 inspectors. None of these complaints were regarded, after investigation, as well founded. 21. Is the present force of inspectors sufficient to compel the proper observance of the existing and proposed regulations? Answer. No ; the present force can not compel proper compliance with existing regulations, and the necessity of applying the tuberculin test to dairy herds hereafter will still further diminish its capacity to accomplish that end. 22. Has a bacteriological laboratory recently been established for the health department? Answer. No; the health department had a bacteriological laboratory for many years. The bacteriological laboratory has. however, up to the early part of the current fiscal year been devoted exclusively to the contagious disease service, having been established and operated from funds appropriated exclu- sively for that service. The appropriation act for the current year, however, approved May 18, 1910, provided $500 for the equipment and maintenance of the bacteriological laboratory, and authorized the bacteriologist employed out of the contagious disease appropriation, under direction of the health officer, to undertake the bacteriological examination of milk and of other dairy prod- ucts and of the water supplies of dairy farms, whether such examinations be or be not directly related to contagious diseases. Since that time, therefore, the health department has undertaken the bacteriological examination of milk. 23. Have any attempts been made, to your knowledge, to secure legislation by Congress affecting the production, transportation, and distribution of milk, under the authority vested in the national legislation to regulate commerce between the several States? Answer. The act of 1895, relating to the production of milk in and for the Dis- trict of Columbia, was made by Congress, quite as much by virtue of its power to regulate interstate commerce as by virtue of its power to legislate for the District of Columbia. The food and drugs act of 1898, enacted by Congress for 368 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. the District of Columbia, regulated the sale of milk and cream In the District of Columbia, and having been enacted by Congress, would doubtless apply quite as well to " original packages " as to any other form in which the milk might be sold. The Federal food and drugs act of June 30, 1906, which is distinctly an interstate act, although it regulates local commerce within the District of Columbia, applies to milk and cream. 24. To what extent are milk products (including also prepared, condensed, modified, and powdered milk) regulated by the provisions of the pure food and drugs act? Answer. So far as the provisions of the act referred to are applicable to the products named, and generally speaking they are applicable to them quite as much as to other food products, the manufacture and sale of milk and milk products (including also prepared, condensed, modified, and powdered milk) is governed by the provisions of said act. 25. Kindly furnish copies, if practicable, or refer the committee to the milk law of 1S95, and any House or Senate bills or documents relating to legislation already in effect and contemplation, or regulations of the health department referring to the subject under investigation by this committee. Answer. A copy of the milk law of 1895, of the regulations promulgated by virtue thereof, of the act regulating the manufacture and sale of foods in the District of Columbia, enacted in 1898, and of the Federal food and drugs act of June 30, 1906, are inclosed herewith ; also copies of the bill now pending look- ing toward the improved regulation of the milk supply of this District. Yours, very truly, Wm. C. Woodward, M. D., Health Officer. Commissioners of the District of Columbia Health Department, Washington, December 20, 1910. Mr. J. Louis Willige, Chairman, etc.. Chamber of Commerce, Washington D. G. Dear Mr. Willige: I beg to acknowledge the receipt of your letter of the 24th ultimo, requesting certain information relative to the milk supply of this District. I regret very much that absence from the city has prevented a more prompt compliance with your request, and hope that the following information will meet your needs. 1. What routine, if any, is prescribed for procuring reports of communicable diseases among dairymen and dairy farmers, and their assistants. Answer. No routine has ever been laid out aimed at this particular end. The reporting of all cases of communicable diseases, with but few exceptions, within the District of Columbia, is required by law. These reports, however, do not state whether the patient or any member of the household is employed on a dairy farm or about a dairy. Such information is obtained by the inspector who visits the premises, and such visits are always made in connection with reported cases of typhoid fever, scarlet fever, and diphtheria, the diseases most likely to be communicated by milk. Outside of the District of Columbia, cases of communicable diseases are not reported to the health officer, whether they occur on dairy farms or not. The employment of any one who has been exposed to diphtheria, scarlet fever, erysipelas, smallpox, anthrax, or other dangerous contagious diseases, in or about the dairy or dairy farm, is forbidden by law. (See sec. 3, an act to regulate the sale of milk in the District of Columbia, etc., approved Mar. 2, 1895.) 2. Are there any restrictions against feeding " wet malt," or other brewery products, to milch cows? Answer. No effort has been made to restrict the feeding of dairy cows with any of the foods named. The only brewery product, however, that, to the knowledge of the health department, is used for milch cows, is wet malt. This, it is believed, can be safely fed until it has begun to sour; after it has begun to sour it is regarded as having spoiled, and its use would not be tolerated any more than the use of any other spoiled food for dairy cows. In the considera- tion of this matter, the committee must bear in mind the difference between wet malt and other brewery products on the one hand, and distillery waste on the other, so as to avoid coming to erroneous conclusions as to the views of various sanitary authorities with respect thereto. 3. Has the feeding of such products a prejudicial effect upon the milk of animals so fed? THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 369 Answer. I do not believe that it has yet been demonstrated that the feeding of fresh sweet brewer's grains has a prejudical effect upon the milk of animals so fed. Attention is invited, however, to the preceding answer. 4. With what average frequency are inspections of dairies and dairy farms made by the health department? Answer. By the term " dairy " is understood a place where the sale of milk and milk products is the principal part of the business carried on. There are in the District of Columbia 60 such places, independently of those located on dairy farms ; those located on dairy farms are inspected as a part of the dairy farm and therefore are not included in the following statement of aver- age frequency of inspection of dairies. The dairies of the District of Columbia, independent of those located on dairy farms, were during the year ended June 30, 1910, inspected on an average of 23.6 times. The dairy farms supply- ing milk to the District of Columbia were during the same year inspected on an average of 8.79 times each. 5. Is there any need for more inspectors under the present regulations? Answer. The number of inspectors of dairy farms should be increased. Be- cause of the distance between dairy farms in outlying districts, a considerable part of the time of any inspector is consumed in going from his headquarters to the various farms and from farm to farm. The proportion of his time that is practically lost in this way is, of course, increased in proportion as the size of his territory is increased, and with the large territories that individual in- spectors now have to cover a very large part of their time is lost in going to and fro. At least one new inspector is urgently needed, and more could be used with advantage. What, however, is most urgently needed is a competent officer of the health department to devote his entire time to the supervision of the food-inspection service. No salary has ever been provided sufficient to tempt into the service any veterinary surgeon or graduate of a dairy school willing to give up his entire time to the work of the office, as proper supervision of the food-inspection service practically requires. The men who have been assigned to this work have been, therefore, men not specially qualified or trained, and however willing they may have been to discharge the duties of their office, they have not always been capable of doing so when put to the test. As an illustration of the difference between the situation in Washington and else- where, it may be stated that New Orleans pays its chief food inspector $200 a month and allows him time for a reasonable amount o'f private work. The chief food inspector in the city of Winnipeg receives $2,000 a year. The most that the District of Columbia has ever paid for this service is $1,200 per annum. 6. What number of additional inspectors will probably be required if a low bacterial content, the tuberculin test, and compulsory pasteurization be required? Answer. It is impossible to answer this question with any degree of accuracy. Four additional employees, for instance, would be sufficient to supervise from a bacteriological standpoint the milk supply of this District in a very satisfactory way. One additional inspector, however, M^ould very much improve the present service, and two would improve it in proportion to the increase in the number of employees. While an increase in the number of employees assigned to the supervision of the milk supply from a bacteriological standpoint would not do away altogether with the necessity for the inspection of the farms, yet if it were permitted to fix an arbitrary bacteriological content and to insist that milk shipped into the District for sale or sold within the District show no greater number of bacteria than that allowed the necessity for the supervision of dairy farms would be very much reduced. A farmer or a dealer in milk can not produce and market a milk containing a small number of bacteria unless his premises and his methods are what may be designated as sanitary. A bac- teriologist examining the milk as it reaches the city and as it is offered for sale can tell quite as much regarding the conditions under which it has been pro- duced, from a general sanitary standpoint, as can the inspector on the farm. The bacteriologist can not, however, determine as accurately as can the inspector on the farm the condition of the dairy cattle, nor can the bacteriologist pick up as well as can the inspector who visits the dairy farm information concerning the presence of contagious diseases in the families of milk producers. It must be borne in mind, of course, that the isolation of disease germs in milk is exceed- ingly difficult, with the possible exception of the isolation of tubercle bacilli, and that the isolation of tubercle bacilli is a slow and somewhat expensive process, which can not well replace the physical and tuberculin testing of the dairy cattle. If all tuberculin testing is to be done by employees of the District government, three additional veterinary inspectors should be provided, for the present at least, when there is a very large number of untested herds to be 82444°— S. Doc. 863, 61-3 24 370 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. looked after. The number of inspectors required to supervise properly the pasteurization of milk would depend upon the number of pasteurizing plants established. Three would probably be a fair estimate for such work. The more important part of the supervision of the pasteurizing plant, it might almost be said, would rest with the inspectors charged with the bacteriological supervision of the milk supply. Generally speaking, therefore, it might be said that if a fixed bacterial standard be established, the tuberculin test required, and compulsory pasteurization insisted upon from six to ten additional in- spectors would be needed properly to supervise the work. 7. What number of dealers are at present purveying milk in the District of Columbia? Answer. The health department has no record of the numerous grocers and other keepers of stores other than dairies who are purveying milk. It is estimated, however, that milk is sold at 2,000 places within the District of Columbia. 8. What number of producers are at present furnishing the milk consumed in the District of Columbia? Answer. The number of licensed dairy farms at present is 1,142. 9. Will you kindly furnish, if possible, a statement of the prices paid to the dairy farmer and by the consumer for milk during the past several years? Answer. The price paid to the dairy farmer during the past five years has been practically unchanged at from 14 to 16 cents for the summer months and 20 to 22 for winter months. The consumer has paid in that time 32 cents in the summer time and 36 to 40 cents in the winter. These prices are per gallon. So-called " special " milk is being sold at 40 cents per gallon throughout the year. 10. What individuals or companies now maintain plants for pasteurizing milk consumed in the District of Columbia? Answer. George M. Oyster, jr., J. J. Bowles, W. A. Simpson, Belmont Dairy Co., J. W. Gregg (no holding device), Nathan Straus Laboratory, all in Wash- ington, D. C. ; Baltimore & Washington White Cross Milk Co., Frederick, Md. ; Tri-State Sanitary Milk Co., Cumberland, Md. ; International Milk Products Co., Cooperstown, N. Y., and the following creameries which ship only cream, so far as is known to this department : Chapin-Sacks Manufacturing Co., Buckeystown, Md., and Woodstock, Va. ; Rosemary Creamery Co., Adams, N. T. 11. Does any present requirement of the health department forbid the use of milk bottles or other receptacles for holding coffee, tea, paint, coal oil, molasses, vinegar, gasoline, etc.? Answer. Section 6a of an ordinance to prevent the sale of unwholesome food and the distribution of medicinal and poisonous substances in the District of Columbia provides as follows: " Sec. 6a. That any person in the District of Columbia who receives milk or cream for sale shall, immediately after emptying the receptacle in which such milk or cream has been received, thoroughly rinse such receptacle so as to free the same from all remnants of milk and of cream, or shall cause such receptacle to be so rinsed ; and no person in said District shall put or, having power and authority to prevent, permit to be put into any receptacle which is commonly used for the storage or delivery of milk or cream for sale anything which is filthy or offensive or any refuse matter of any kind. Any person violating the provisions of this section shall, upon conviction thereof, be pun- ished by a fine not exceeding $25 for each and every such offense." (Commis- sioners' Regulation of Apr. 21, 1903.) The health department has prosecuted persons who have failed to rinse the receptacles in which milk or cream .has been received, such prosecutions being against, as the regulation quoted above will indicate, persons who have received milk or cream for sale. Cases in which householders have used the receptacles in which milk or cream has come into their possession for pur- poses suggested by the question propounded by the committee have not been prosecuted by the health department, for the simple reason that the health department does not obtain knowledge of such offenses, and the milk dealers who do obtain knowledge of such offenses have never appeared to enter com- plaint against their customers. 12. What is the temperature maintained in household refrigerators in the Dis- trict of Columbia? Answer. The health department is unable to answer this question. 13. In what respect, if any, is the drinking of sour milk deleterious? Answer. The drinking of sour milk is ordinarily not injurious to health. The milk that seems to do harm is not milk that is actually and manifestly soured, but milk that is more or less advanced in the process of souring. Whether this is due to the fact that up to a certain point disease-producing THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 371 organisms multiply in milk, whereas at a later period by reason of the changes produced by the ordinary milk bacteria such disease-producing organisms are either killed or inhibited in their action, or whether the injurious effect that seems to follow in many cases from the drinking of old and partially soured milk results from changes in the process of souring that follow its ingestion, is not clear. 14. Has the health department expressed any views as to the desirability of compulsory pasteurization? Answer. Yes. In the present state of the production and sale of milk com- mercially, pasteurization seems to be the only way of safeguarding the public health against milk-borne diseases. There will, however, probably always be some use for raw milk, either as a medicinal agent or for culinary purposes, or for use by the exceptional individual, similar to the individual who now without any physical necessity uses raw meat and raw eggs, and therefore there appears to be no reason why the sale of raw milk should be forbidden. 15. Has a bacteriological laboratory been recently established in connection with the health department, and on what date? Answer. This question was answered, it is believed, in the answers previously submitted to the committee. Briefly, however, a bacteriological laboratory has. not been recently established in connection with the health department, but such a laboratory has been used by the department for some years past. Until the beginning of the current fiscal year, however, that laboratory was devoted exclusively to the contagious-disease service, because it was maintained from the appropriation provided for the maintenance of that service. With legisla- tion enacted by Congress at its last session it became possible to use this laboratory for other purposes, and with the beginning of the fiscal year its use for such other purposes, notably for milk work, was begun. 16. Are additional or better facilities desired for this laboratory? Answer. The laboratory is in need of additional room. It is possible to operate it on its present basis only by the detail of a sanitary inspector to assist the bacteriologist, and in order to obtain an inspector to do this work it has been necessary to train him. There should be provision for an assistant bacteriologist, with salary and prospects suflicient to bring into the service a generally trained bacteriologist, say with an initial salary of $1,500 per annum, with some assurance of promotion in event of giving satisfactory service. Pro- vision should be made for the more general supervision from a bacteriological standpoint of the milk supply of the District, by providing for from one to four minor assistants in the bacteriological laboratory, and if such assistants be provided it will be necessary to have additional equipment as well as addi- tional space. 17. In your judgment will the specification of 500,000 bacteria to the cubic centimeter suffice as a maximum indication of acceptable milk, or should this number be decreased, and if so to what figure? Answer. In the present state of the production and vending of milk, 500,000 bacteria per cubic centimeter represents a fair standard. Good raw milk should contain not in excess of that number, but it will hardly be practicable during the summer season to prosecute for every sample of milk that contains a number in excess of the standard suggested. In the case of pasteurized milk, a bacterial standard should be fixed not in excess of 50,000 per cubic centimeter. If bacterial standards are to be fixed by law, it might be well to provide gen- erally that no milk should be sold having a higher bacterial content than that claimed for it by the vender, so that the producer and vender of special grades of milk who claims for such milk a bacterial count not in excess of say 10,000 per cubic centimeter could not with impunity sell to his customer milk contain- ing a greater number. 18. Can you refer the committee to a statement of the present requirements of the health department as to stabling cows, etc.? Answer. A copy of the regulations of the department relative to the stabling of cows is inclosed herewith. 19. Can you conveniently furnish copies of all orders of the health department at present in operation governing the production and sale of milk? Answer. The production and sale of milk is governed rather by laws and regulations, copies of which have already been furnished the committee, than by orders of the health department. Orders of the health department are gen- erally directed to the employees of the department, and thereupon departmental interpretations of existing laws and regulations. Copies of all such orders can not be easily furnished, but if the committee desires copies of such orders relating to any particular feature of the milk-inspection work, copies of such orders will be made and furnished. 372 THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. The department staads ready to furnish the committee with any other infor- mation in its possession which the committee believes will be of service to its work. Respectfully, Wm. C. Wooodward, M.

The health department believes that if a cow is suffering from tuberculosis her entire value as a dairy cow is gone. If she is suffering from an Inflammatory disease of the udder as well as from tuberculosis, she becomes even a greater danger to the herd. And If she Is furthermore otherwise diseased or out of condition or dirty she becomes even a more serious menace to public health. For these reasons the above system of scoring has been arranged so that an individual cow may count against the score of the entire herd more than would have been allotted to her had she been in perfect condition. All cows stabled with the dairy herd or found in the milking line will be scored as part of the herd.

Sec. 4. That the examinations of specimens of foods and drugs shall be made in the Bureau of Chemistry of the Department of Agriculture, or under the direction and supervision of such bureau, for the purpose of determining from such examinations whether such articles are adulterated or misbranded within the meaning of this act ; and if it shall appear from any such examination that any of such specimens is adulterated or misbranded within the meaning of this act, the Secretary of Agriculture shall cause notice thereof to be given to the party from whom such sample was obtained. Any party so notified shall be given an opportunity to be heard, under such rules and regulations as may be prescribed as aforesaid, and if it appears that any of the provisions of this act have been violated by such party, then the Secretary of Agriculture shall at once certify the facts to the proper United States district attorney, with a copy of the results of the analysis or the examination of such article duly authenticated by the analyst or officer making such examination, under the oath of such officer. After judgment of the court, notice shall be given by publication in such manner as may be prescribed by the rules and regulations aforesaid. Sec. 5. That it shall be the duty of each district attorney to whom the Secre- tary of Agriculture shall report any violation of this act, or to whom any health or food or drug officer or agent of any State, Territory, or the District of Columbia shall present satisfactory evidence of any such violation, to cause appropriate proceedings to be commenced and prosecuted in the proper courts of the United States, without delay, for the enforcement of the penalties as in such case herein provided. Sec. 6.

Sec. 9. That no dealer shall be prosecuted under the provisions of this act when he can establish a guaranty signed by the wholesaler, jobber, manufac- turer, or other party residing in the United States, from whom he purchases such articles, to the effect that the same is not adulterated or misbranded within the meaning of this act, designating it. Said guaranty, to afford pro- tection, shall contain the name and address of the party or parties making the sale of such articles to such dealer, and in such case said party or parties shall be amenable to the prosecutions, fines, and other penalties which would attach, in due course, to the dealer under the provisions of this act. Sec. 10. That any article of food, drug, or liquor that is adulterated or mis- branded within the meaning of this act, and is being transported from one State, Territory, District, or insular possession to another for sale, or, having been transported, remains unloaded, unsold, or in original unbroken packages, or if it be sold or offered for sale in the District of Columbia or the Territories, or insular possessions of the United States, or if it be imported from a foreign country for sale, or if it is intended for export to a foreign country, shall be liable to be proceeded against in any district court of the United States within the district where the same is found, and seized for confiscation by a process of libel for condemnation. And if such article is condemned as being adulter- ated or misbranded, or of a poisonous or deleterious character, within the meaning of this act, the same shall be disposed of by destruction or sale, as the said court may direct, and the proceeds thereof, if sold, less the legal costs and charges, shall be paid into the Treasury of the United States, but such goods shall not be sold in any jurisdiction contrary to the provisions of this act or the laws of that jurisdiction : Provided, however, That upon the pay- ment of the costs of such libel proceedings and the execution and delivery of a good and sufficient bond to the effect that such articles shall not be sold or otherwise disposed of contrary to the provisions of this act, or the laws of any State, Territory, District, or insular possession, the court may by order direct that such articles be delivered to the owner thereof. The proceedings of such libel cases shall conform, as near as may be, to the proceedings in admiralty, except that either party may demand trial by jury of any issue of fact joined in any such case, and all such proceedings shall be at the suit of and in the name of the United States. Sec. 11. The Secretary of the Treasury shall deliver to the Secretary of Agriculture, upon his request from time to time, samples of foods and drugs which are being imported into the United States or offered for import, giving notice thereof to the owner or consignee, who may appear before the Secretary of Agriculture, and have the right to introduce testimony, and if it appear from the examination of such samples that any article of food or drug offered to be imported into the United States is adulterated or misbranded within the meaning of this act, or is otherwise dangerous to the health of the people of the United States, or is of a kind forbidden entry into, or forbidden to be sold or restricted in sale in the country in which it is made or from which it is TH!e milk situation in the district of COLUMBIA. 381 exported, or is otherwise falsely labeled in any respect, the said article shall be refused admission, and the Secretary of the Treasury shall refuse delivery to the consignee and shall cause the destruction of any goods refused delivery which shall not be exported by the consignee within three months from the date of notice of such refusal under such regulations as the Secretary of the Treasury may prescribe : Provided, That the Secretary of the Treasury may de- liver to the consignee such goods pending examination and decision in the mat- ter on execution of a penal bond for the amount of the full invoice value of such goods, together with the duty thereon, and on refusal to return such goods for any cause to the custody of the Secretary of the Treasury, when demanded, for the purpose of excluding them from the country, or for any other purpose, said consignee shall forfeit the full amount of the bond : And provided further, That all charges for storage, cartage, and labor on goods which are refused ad- mission or delivery shall be paid by the owner or consignee, and in default of such payment shall constitute a lien against any future importation made by such owner or consignee. Sec. 12. That the term " Territory " as used in this act shall include the insular possessions of the United States. The word " person " as used in this act shall be construed to import both the plural and the singular, as the case demands, and shall include corporations, companies, societies, and associations. When construing and enforcing the provisions of this act, the act, omission, or failure of any officer, agent, or other person acting for or employed by any corporation, company, society, or association, within the scope of his employ- ment or office, shall in every case be also deemed to be the act, omission, or failure of such corporation, company, society, or association as well as that of the person. Sec. 13. That this act shall be in force and effect from and after the first day of January, nineteen hundred and seven. Approved, June 30, 1906. APPENDIX N. COMMUNICATION FROM CHIEF OF BUREAU OF CHEMISTRY, UNITED STATES DEPARTMENT OF AGRICULTURE, REFERRING TO PROSECUTIONS UNDER FEDERAL PURE-FOOD LAW. United States Department of Agricultube, Bureau of Chemistry, Washington, D. C, December 2, 1910. The Washington Chamber of Commerce, Washington, D. G. Gentlemen : In further reply to your inquiries respecting standards for milk, I am transmitting, in accordance with your request of November 18, additional data bearing specifically upon the question which your committee is so carefully considering. Attached to this is also a memorandum prepared by the assistant chief of this bureau. Dr. W. D. Bigelow, and copies of certain notices of judg- ment obtained as a result of prosecutions secured against interstate shipments of milk. I need not assure you again how earnestly this bureau is endeavoring to coop- erate with you in your efforts to secure a proper milk supply. In this connection I beg to say that the ordinary pasteurized milk of commerce is a dangerous article — far more so than the so-called raw milk. I may say that as many as 54,000,000 organisms per cubic centimeter have been found in milk alleged to have been pasteurized 24 hours after the pasteurization is said to have been accomplished. Pasteurized milk is only to be tolerated when certified by an independent official as to the efficiency of pasteurization and the suitability of it for consumption. Respectfully, H. W. Wiley, Chief. 382 THE MILK SITUATION IN THE DISTEICT OF COLUMBIA. memorandum fob dr. wiley. United States Department of Agriculture, Bureau of Chemistry, Washington, D. C, Decemher 1, 1910. In the inspection of milk shipped into interstate commerce the bureau adheres to the standards promulgated by the Secretary of Agriculture respecting the composition of milk. No prosecutions are actually brought, however, for the shipment of milk which very nearly complies with those standards. Prosecutions have been successfully maintained for the shipment in interstate commerce of milk shown by chemical analysis to be adulterated, as, for instance, by skimming, by the addition of water or ice, or by the addition of formaldehyde. Prosecutions have also been maintained for the shipment of badly contaminated milk on the ground that it was filthy, decomposed, and putrid, and contained filthy, decomposed, and putrid material. This question is judged by its bacteriological condition. There are now pending in the court, or preparing for the courts, about 170 cases of violations of the food and drugs act by shipping adulterated milk and cream. The following notices of judgment, copies of which are attached hereto, refer to cases which have already been prosecuted : N. J. 5, 37, 81, 88, 125, 132, 185, 206, 214, 219, 223, 228, 229, 241, 264, 265, 267, 268, 273, 285, 287, 307, 308, 312, 331, 335, 336, 338, 347, 370, 419, 420, 421, 423, 425, 430, 437, 445, 446, 451, 460, 479. 484, 485, 502, 503, 510, 512, 513, 514, 515, 517, 521, 522, 523, 524, 525, 526, 527, 528, 538, 557, 558, 586, 587, 588, 590, 607, 628, 629, 632, and 638. W. D. BiGELOW. APPENDIX O. SUGGESTIONS CONCERNING SANITARY ARRANGEMENTS FOR DAIRY FARMS. By Ed. H. Webster, Chief of Dairy Division, Bureau of Animal Industry, United States Department of Agriculture. [Reprinted from Bulletin No. 56, Hygienic Laboratory, United States Public Health and Marine-Hospital Service, pp. 570, 571.] Twenty-one Suggestions. THE cows. 1. Have the herd examined frequently by a skilled veterinarian. Promptly remove any animals suspected of being in bad health. Never add an animal to the herd until certain it is free from disease, especially tuberculosis. 2. Never allow a cow to be excited by hard driving, abuse, loud talking, or unnecessary disturbances ; do not unduly expose her to cold or storms. 3. Clean the entire body of the cow daily. Hair in the region of the udder should be kept short. Wipe the udder and surrounding parts with a clean, damp cloth before milking. 4. Do not allow any strong flavored feed, such as garlic, cabbage, or turnips, to be eaten except immediately after milking. 5. Salt should always be accessible. 6. Radical changes in feed should be made gradually. 7. Have fresh, pure water in abundance, easy of access, and not too cold. THE STABLES. 8. Dairy cattle should be kept in a stable where no other animals are housed, preferably without cellar or storage loft. Stable should be light (4 square feet of glass per cow) and dry, with at least 500 cubic feet of air to each animal. It should have air inlets and outlets, so arranged as to give good ventilation without drafts of air on cows. The presence of flies may be reduced by dark- ening the stable and removing the manure as directed below. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA, 383 9. The floor, walls, and ceilings of the stable should be tight, walls and ceil- ings being kept free of cobwebs and whitewashed twice a year. There should be as few dust-catching ledges and projections as possible. 10. Allow no musty or dirty litter or strong smelling material in the stable. Store manure under cover at least 40 feet from the stable in a dark place. Use land plaster daily in gutter and on floor. THE MILK HOUSE. 11. Cans should not remain in the stable while being filled. Remove the milk of each cow at once from the stable to a clean room ; strain immediately through cotton flannel or absorbent cotton; cool to 50° F. as soon as strained; store at 50° F. or lower. All milk houses should be screened. 12. Milk utensils should be made of metal, with all joints smoothly soldered, or, when possible, should be made of stamped metal. Never allow utensils to become rusty or rough inside. Use milk utensils for nothing but handling, stor- ing, or delivering milk. 13. To clean dairy utensils, use pure water only. First rinse the utensils in warm water ; then wash inside and out in hot water in which a cleansing mate- rial has been dissolved ; rinse again ; sterilize with boiling water or steam ; then keep inverted in pure air that may have ready access, and sun if possible, until ready for use. MILKING AND HANDLING MILK. 14. The milker should wash his hands immediately before milking and should milk with dry hands. He should wear a clean outer garment, which should be kept In a clean place when not in use. Tobacco should not be used while milking. 15. In milking be quiet, quick, clean, and thorough. Commence milking at the same hour every morning and evening and milk the cows in the same order. . 16. If any part of the milk is bloody, stringy, or unnatural in appearance, or if by accident dirt gets into the milk pail, the whole mess should be rejected. 17. Weigh and record the milk given by each cow. 18. Never mix warm milk with that which has been cooled, and do not allow milk to freeze. 19. Feed no dry, dusty feed just previous to milking. 20. Persons suffering from any disease, or who have been exposed to a con- tagious disease, must remain away from the cows and the milk. 21. It is needless to say that the shorter the time between the production of milk and its delivery, and between delivery and use, the better will be the quality of the milk. APPENDIX P.

APPENDIX U. RESOLUTION OFFERED BY MR. LEVER, OF SOUTH CAROLINA, AUTHORIZING THE COMMITTEE ON AGRICULTURE, HOUSE OF REPRESENTATIVES, TO INVESTIGATE TO WHAT EXTENT TUBERCULOSIS IS PREVALENT AMONG DAIRY AND FARM ANIMALS IN THE DISTRICT OF COLUMBIA, ETC. [H. Res. 605, Sixty-first Congress, second session.] Whereas it appears from the official reports issued by the Department of Agri- culture, particularly during the past two years, that the alarming prevalence of tuberculosis in the human family in all parts of the United States and the District of Columbia and the prevalence of typhoid fever and other diseases which endanger the public health are due to a considerable extent to the con- sumption of milk and cream obtained from diseased cows and to the consump- tion of butter produced from milk and cream which contain tubercle bacilli and typhoid bacilli ; and "Whereas it is stated in said official reports that typhoid bacilli will remain alive and ^-irulent in butter manufactured from milk infected with such bacilli for a period of at least one hundred and fifty-one days, and that during this period of time these bacilli are ready to multiply whenever placed in suitable environment ; that tubercle bacilli may remain alive and virulent in ordinary salted butter fully one hundred and sixty days after its manufacture from milk and cream infected with such bacilli; and further that more than one sample out of every twenty samples of commercial or market milk from vari- ous dairies supplying milk to the city of Washington were, by application of the tuberculin test, recently found to be infected with tubercle bacilli, thereby causing great danger to the public health; and Whereas it is also stated that ten per centum of all dairy cows in the United States are infected with tuberculosis ; and Whereas it is also stated in said official reports that the financial loss which is chargeable to the prevalence of tuberculosis among farm animals amounts to no less than twenty-three million dollars annually and is dangerously on the increase : Therefore be it Resolved, That the Committee on Agriculture of the House of Representatives be, and it hereby is, authorized and directed to investigate and ascertain the condition of milk, cream, cheese, and butter offered for sale or transportation in the District of Columbia ; report to the House of Representatives its find- ings as to the extent to which tuberculosis and other diseases are com- municated to the human family by the sale of such infected articles of food, and to what extent tuberculosis is prevalent among farm and dairy animals in the District of Columbia, and report to the House of Representatives the reason for the failure to enforce the pure-food law as it affects butter and butter products in the United States. 394 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA.

Dear Sir: The department is in receipt of your letter of the 28th instant, requesting to be advised whether it is contemplated to prepare a circular along THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 401 the lines of Circular 114 of the Department of Agriculture, with reference to milk supplied to employees in this department during luncheon hour. In reply thereto I beg to inform you that as the quantity of milk taken by the employees of this department amounts to almost nothing, no action in this respect is con- templated. Respectfully, O. J. Field, Chief Clerk. Smithsonian Institution, Washington, December 8, 1910. Deab Mr. Willige : In reply to your communication of November 28, with reference to establishing a restrictive standard for the milk supplied to em- ployees at the lunch hour, there has been )io order issued by the Institution or its branches in this connection. Very truly, yours, O. D. Walcott, Becretary. Mr. J. Louis Willige, Chairman Special Committee, The Washington Chamber of Commerce, Washington, D. G. Office of the Public Printer, Washington, December 1, 1910. Sir: This will acknowledge receipt of your communication of the 28th instant, making inquiry as to the rules governing the sale of milk to employees in the Government Printing Office. In reply, I have the honor to advise that dealers to whom permits are issued by the Public Printer authorizing them to sell milk in the Government Printing Office are first required to furnish satisfactory evidence that they have been authorized by the health department of the District of Columbia to sell milk. Any deviation from this practice has not up to this time been contemplated. Respectfully, Saml. B. Donnelly, J. Louis Willige, Esq., Washington Chamber of Commerce, Washington, D. Public Printer. Building and Grounds, Library of Congress, Office of the Superintendent, Washington, D. C, January 4, 1911. Mr. J. Louis Willige, Washington Chamber of Commerce, Washington, D. C. My Dear Sir : Your letter of November 28, 1910, addressed to the Librarian of Congress, on behalf of a special committee of the Washington Chamber of Commerce, on the subject of milk supplied to the Library of Congress em- ployees, was referred to me as the officer in charge of the Library Building. It is my duty to explain that the delay in my reply has been due somewhat to the unusual nature of the question and uncertainty as to the scope and application of Circular No. 114 of the Bureau of Animal Industry of the Department of Agriculture to which it refers. Now that I have been able to read it rather carefully, I am prepared to state that I feel quite sure that should the Government departments issue an order regulating the quality of the supply of milk furnished to the lunch rooms and employees in their several buildings the Library of Congress would do likewise, and, furthermore, that should the Department of Agriculture issue such an order the Library of Congress would follow it as far as practicable. Yours, very truly, Bernard R. Green, Superintendent. 82444°— S. Doc. 863, 61-3 26 402 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA, APPENi:)IX AA.

ORDER OF DISTRICT COMMISSIONERS FOR COMPULSORY TUBERCULIN TEST- ING OF CATTLE WITHIN DISTRICT OF COLUMBIA, PROMULGATED NOVEM- BER 27, 1909, TOGETHER WITH AMENDMENT OF MARCH 5, 1910. United States Department of Agriculture, BUREAU of animal INDUSTRY. order of THE commissioners OF THE DISTRICT OF COLUMBIA FOR THE SUPPRESSION and prevention of tuberculosis in cattle. Executive Office, Commissioners of the District of Columbia, Washington, November 26, 1909. Ordered: The Commissioners of the District of Columbia having learned that tuberculosis, a communicable disease, prevails among the cattle in the District of Columbia and adjacent States, do hereby, pursuant to law, authorize and direct the follovping measures for the prompt suppression and to prevent the spread of bovine tuberculosis within the District of Columbia and to adjoining States ; Section 1. It is hereby ordered that no cattle shall, in any manner, be re- moved from the District of Columbia except upon written permission from the Chief of the Bureau of Animal Industry or the health officer of the District of Columbia, which removal shall only be granted for cattle which have success- fully passed an official tuberculin test, or are for immediate slaughter at an establishment at which United States meat inspection is maintained. Sec 2. Any person, firm, or corporation desiring to bring any cattle into the District of Columbia, except as provided in section 3, paragraph (c), shall first make application and obtain a permit from the Chief of the Bureau of Animal Industry or from the health officer of the District of Columbia. The said, application shall be in writing, stating the number, sex, and the age of the cattle, whether over or under 6 months old, the exact place, date, and time at which it is desired to enter said cattle, and their destination within the District of Columbia, together with a declaration showing clearly the purpose for which the cattle are desired to be entered, whether for immediate slaughter, feeding, or breeding purposes, or for milk production. Sec. 3. (a) Cattle offered for entry into the District of Columbia must be accompanied by a permit, as provided in section 2, and must be identified by an official veterinarian of the Bureau of Animal Industry or of the health depart- ment of the District of Columbia, and must be appropriately tagged before entrance is permitted, except as provided in paragraph (c) of this section. (6) Cattle over 6 months old, foi purposes other than inunediate slaughter, unless accompanied by a satisfactory certificate of tuberculin test by a vet- erinary inspector of the Bureau of Animal Industry or an official veterinarian of the health department of the District of Columbia or of the State from which THE MILK SITUATIOISr IN THE DISTRICT OF COLUMBIA. 403 brought, must be imrnediately taken after identification, as provided in para- grapb (a) of this section, to a place designated by the Chief of the Bureau of Animal Industry or health officer of the District of Columbia, and there quar- antined apart from all other cattle until officially tuberculin tested and dis- posed of in accordance with these regulations : Provided, That no indemnity shall be allowed for such cattle as shall be slaughtered on account of their being deemed to be tuberculous. When accompanied by certificate of tuberculin test, as herein provided, the said certificate must show the place and the date, within thirty days of being offered for entry, of inspection and tuberculin testing, also temperature chart, description of the animal or animals, age, markings, and tag numbers, if tagged. (c) Cattle for immediate slaughter may enter the District of Columbia if tagged in accordance with paragraph (a) and without the tuberculin test, on condition that the tag therein provided for shall remain attached to the hide * until removed in the presence of an employee of the Bureau of Animal Industry or of the health department of the District of Columbia, to either of whom it shall be delivered. The owner of the animal at the time of slaughter is hereby required to notify the Chief of the Bureau of Animal Industry or the health officer of the District of Columbia, stating the place where the hides will be found. If shipped in cars and consigned direct to an establishment having United States meat inspection, cattle for immediate slaughter may enter the District of Columbia without complying with section 2 and section 3, paragraph (a) : Provided, hoivever, That the consignee shall keep a complete record of each animal received, date of receipt, its place of origin, railroads traversed, name of shipper, and butcher class to which each animal belongs, a-nd shall report the same before the slaughter of any such animals to the Chief of the Bureau of Animal Industry through the veterinary inspector stationed at that establishment. id) Cattle under 6 months old for purposes other than immediate slaughter, when not accompanied by certificates as indicated in paragraph (6), may be brought into the District of Columbia as provided in paragraph {a), but said cattle must be accompanied by affidavits by the breeder or feeder and by the owner or shipper, said affidavits to state that tuberculosis has not been known to exist on the premises, during tlie six months immediately preceding the offer for entry, upon which said animals have been kept. Sec. 4. Cattle over 6 months old already within the District of Columbia shall be inspected and tuberculin tested by a veterinary inspector of the Bureau of Animal Industry or of the health department of the District of Columbia. Cat- tle under 6 months old shall, in the same manner, be inspected, and when deemed necessary shall be tuberculin tested, said inspection and tuberculin testing to be repeated annually, or at such times as the Chief of the Bureau of Animal Industry or the health officer of the District of Columbia may direct. All such cattle shall be oflicially tagged " U. S., B. A. I,," with a serial number, or " U. S., B. A. I., Reacted," with a serial number. Sec. 5. All cattle already within the District of Columbia which are deemed to be tuberculous, either as a result of physical examination or the tuberculin test, shall be slaughtered within a time and at a place designated by the Chief of the Bureau of Animal Industry or the health officer of the District of Colum- bia, and shall be subject to official post-mortem inspection, and the carcass of any such animal shall be disposed of according to the meat-insi^ection regula- tions of the Bureau of Animal Industry. All such cattle shall be appraised before being slaughtered, the owners to be indemnified, as hereinafter provided, from any available appropriation made by Congress for the Bureau of Animal Industry of the United States Department of Agriculture for carrying out the provisions of the act of May 29, 1884, except as specified in section 8 of these regulations : Provided, That no liability shall be incurred under these regula- tions by the United States Department of Agriculture in excess of the funds available from the aforesaid appropriation of Congress, and whenever the Chief of the Bureau of Animal Industry shall deem it necessary or advisable, because of the lack of funds for the aforesaid purpose, he shali notify the health officer of the District of Columbia to that effect, and thereafter no liabilities shall accrue against the United States on account of any act done or permitted under these regulations. Sec. 6. (a) The health officer of the District of Columbia shall designate or request the Chief of the Bureau of Animal Industry to designate an appraiser, who shall appraise each animal within five days prior to the date of slaughter, basing the amount upon the class and market value of the animal at the time of the appraisal, whether for breeding purposes or for meat or milk production. 404 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. Animals reacting to the tuberculin test but not exhibiting any physical evi- dence of tuberculosis shall be appraised without considering the presence of a diseased condition, but animals exhibiting any physical evidence of tuberculosis shall be appraised as diseased animals. The amount of appraisal shall not in any case exceed the sum of seventy-five dollars for a purebred and registered animal, or the sum of fifty dollars for a grade or nonregistered animal. If the amount of appraisal of any animal, as determined by the appraiser designated, is not satisfactory to the ovi^ner or owners of such animal, a written notice of such fact, setting forth the reasons for complaint, shall be forwarded upon the day of appraisal to the health oflicer of the District of Columbia. The amount of the appraisal shall then be determined by arbitrators, one to be appointed by the health officer of the District of Columbia or the Chief of the Bureau of Animal Industry and one by the owner or owners of the animal or animals. If the said arbitrators are not able to agree as to the amount of appraisal, a third arbitrator shall be appointed by them, whose decision shall be final. Arbitrators shall be paid at a rate of compensation not to exceed five dollars per diem and necessary expenses. Compensation for the arbitrator appointed by the owner, and the third arbitrator, if appointed, shall be paid from the fund of the United States Department of Agriculture if the decision made is against the arbitrator appointed by the health officer or the Chief of the Bureau of Animal Industry, but if the decision is in favor of such arbitrator the owner shall pay the compensation of the arbitrator appointed by him, and the third arbitrator, if appointed. (6) Following the appraisal of animals, in accordance with paragraph (a) of this section, the amount of reimbursement shall be determined by the results of post-mortem inspection according to the following rules : Rule 1. If any animal is found, upon post-mortem inspection, not to be affected with tuberculosis, the carcass and other edible portions shall be passed for food, and the owner shall sell the same, including all accompanying parts, for a reasonable price, which price shall be deducted from the amount of appraisal, and the balance, if any, thus remaining, shall be paid from any fund available for that purpose. Rule 2. If any animal is found, upon post-mortem inspection, to be affected with tuberculosis, and the lesions are such that the carcass and parts of the carcass are passed for food, the owner shall sell the same, including all ac- companying parts, for a reasonable price, which price shall be deducted from eighty per centum of the amount of the appraisal, and the balance, if any, thus remaining shall be paid from any fund available for that purpose. Rule 3. If any animal, upon post-mortem inspection, is condemned for offal, the owner' shall sell the hide for a /reasonable price, which price shall be de- ducted from forty per centum of the amount of the appraisal, and the balance, if any, thus remaining shall be paid from any fund available for that purpose. Sec, 7. Any premises upon which there have been kept animals affected with tuberculosis shall be disinfected promptly after the removal of such animals, and in a manner satisfactory to the Chief of the Bureau of Animal Industry or the health officer of the District of Columbia, said disinfection to be at the expense of the owner or owners of the premises or of the owner of the animals. Sec. 8. Any owner, shipper, or common carrier bringing any cattle into the District of Columbia in violation of these regulations will be liable to prosecu- ton, and the cattle shall be immediately removed, at the owner's expense, from the District of Columbia. Such cattle, however, may remain in the District of Columbia if inspected and tuberculin tested under the following conditions: The owner or owners shall first sign an agreement providing for the inspection and tuberculin test by a veterinary inspector of the Bureau of Animal Industry or of the health department of the District of Columbia, and if any one or more of the said animals should then be deemed tuberculous, that he or they will cause such animals to be slaughtered in accordance with the specifications of section five of these regulations; and further, that no claim for reimburse- ment for any loss which might be thus sustained will ever be made against the United States Department of Agriculture, or any other branch of the United States Government, or the District of Columbia, or any officer or department thereof. Sec. 9. Any person violating any of these regulations, or entering cattle by fraudulent means, or using false or fraudulent tags, or interfering in any way with the work of any official, or using any false or fraudulent means to enable any cattle to pass the tuberculin test, shall be punished by a fine of not more than forty dollars nor less than five dollars.

By the American Veterinary Medical Association, in annual meeting assem- bled, at Chicago, 111., in the month of September, in the year 1909, the follow- ing gentlemen were constituted an international commission to study the methods of the control of bovine tuberculosis and to submit a report to the association on the occasion of its next annual meeting: J. G. Rutherford, Leonard Pearson, V. A. Moore, Hon. W. D. Hoard, Frederick Torrance, E. C. Schroeder, M. H. Reynolds, Hon. W. C. Edwards, C. A. Hodgetts, M. D., J. R. Mohler, Louis F. Swift, and J. W. Flavelle. The commission met in Buffalo, N. Y., on the 15th day of December. 1909, and elected as chairman Dr. J. G. Rutherford, of Ottawa, Canada, and as secretary Dr. M. H. Reynolds, of St. Paul, Minn. Owing to the death of Dr. Leonard Pearson and the inability to act of Mr. Louis F. Swift, the president appointed in the stead of these gentlemen, respec- tively. Dr. M. P. Ravenel, of Madison, Wis., and Mr. T. W. Tomlinson, of Denver, Colo. Later, at the request of the commission, the president appointed Mr. J. J. Ferguson, of Chicago, 111., as representative of the United States packing industry, and Dr. J. N. Hurty, of Indianapolis, Ind., as representative of the medical health officers of the United States. The President of the American Veterinary Medical Association: < Owing to the great economic and sanitary significance of animal tuberculosis to the live-stock industry of America and the many and varied factors which must of necessity be accounted with in formulating successful measures for its eradication, the American Veterinary Medical Association, at its meeting in Chicago in September, 1909, appointed the international commission on the control of bovine tuberculosis. The commission was instructed to study the problem of tuberculosis among cattle and to report at the next meeting of the association upon reasonable and economically practicable methods or systems to be recommended to both officials and live-stock owners for eradicating this great scourge of domesticated animals. It is recognized that tuberculosis is widely prevalent among cattle and other animals, and that the frequency with which this great evil occurs is increasing rather than declining. As tuberculosis is one of the strictly preventable infec- tions, there is good ground for the belief that through the formulation and enforcement of proper regulations the disease may eventually be entirely suppressed. The commission has held four meetings, as follows : Buffalo, N. Y., December 13 and 14, 1909 ; Detroit, Mich., March 1 and 2, 1910 ; Ottawa, Canada, May 19, 20, and 21, 1910; Madison, Wis., June 27 and 28. 1910, all of which were well attended, very few of the members having on any occasion been absent. The commission begs to present as a result of its labors the following report, which. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 407 although brief, will, on examination, be found to comprise the principal points essential to the promulgation of a comprehensive and practical policy, such as may reasonably be adopted by any governmental body interested in the control of bovine tuberculosis. It is quite unnecessary, in view of the extensive knowledge already possessed by all who are familiar with the efforts which have hitherto been made to secure control of bovine tuberculosis, to dwell at any length upon the importance of the subject or upon the conditions which led to the formation of the commission. In view of the personnel of the commission as selected by the American Vet- erinary Medical Association, and of the fact that so much information on the subject has been made available through the work of similar bodies in other countries and the researches of scientific and practical men in America and else- where, the commission has not deemed it necessary to take any evidence either from expert witnesses or others. The members fully understood that the purpose which their appointment was intended to serve was less the acquisition of new knowledge regarding bovine tuberculosis than the careful study of the knowledge already available and of the thoughts and opinions of those most entitled to speak with authority on the subject. The conclusions reached in this report are therefore simply the outcome of an earnest and thoughtful consideration of the various modern aspects and phases of the problem, with the object of crystallizing public opinion and so clearing the way for legislative action. They realized also that they could deal with fundamental principles only and that the details of any policy which they might outline must in each case be worked out by the duly authorized and responsible representatives of the com- munity immediately concerned. They nevertheless deemed it essential to study closely the history of the various efforts hitherto made by such countries throughout the world as have attempted to legislate on the subject. This naturally led to the gradual elimination of all methods other than such as might reasonably be adopted by any community desiring in full light of present-day knowledge to undertake the control of bovine tuberculosis. It was felt, in view of the prevalence of the disease, especially in some locali- ties and among certain classes of cattle, the difficulty of providing a sufficient number of trained officials and the large economic questions involved, to say nothing of the enormous expenditure, that it would be unwise, for the present at least, to seriously discuss a policy of universal compulsory testing and slaughter. Such a policy might perhaps be adopted with advantage by a small com- munity or one in which the disease existed to a very limited extent, but, speak- ing generally, especially in view of past experiences in this line, it was thought better to omit it entirely from the recommendations of the commission. All other methods of dealing with bovine tuberculosis which have been recom- mended or tried in various communities were thoroughly discussed, with the object of discarding weak points and adopting such features as might be deemed worthy of a place in the official findings of the commission. Every phase of the subject was in this way fully and freely considered, it being thought best to cover the whole ground as completely as possible before coming to a definite decision on any one point. In order to still further minimize the risk of omitting from the deliberations of the commission any phase of the question four committees were appointed at the first meeting to deal, respectively, with : (1) Education and legislation, (2) Location of tuberculosis. (3) Dissemination. (4) Disposition of tuberculous animals. The appointment of these committees proved to be of the greatest possible Talue in concentrating the energies of the various members on those branches of the subject with which they were most familiar, and their reports presented at subsequent meetings enabled the commission to reach satisfactory conclu- sions much more rapidly than would otherwise have been the case. As a means of furnishing information as to the reasons for these conclu- sions and the manner in which they were reached, the commission would rec- ommend that the reports of the committees should be published as an appendix to this report. The commission recognizing after careful study that the tuberculin test is the fundaiflental factor in any policy having for its object the control of 408 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. bovine tuberculosis, decided that a pronouncement to that effect should prop- erly occupy a foremost place. Based on the information contained in the reports of its committees and on such other information as was brought out in the general discussions of the commission, the following resolutions were adopted for presentation to the American Veterinary Medical Association. Resolution 1. — Dissendnation. As a general policy to be observed all contact between tuberculous and healthy cattle and between healthy cattle and stables, cars, etc., which may contain living tubercle bacilli sliould be prevented. To accomplish this, the following specihc recommendations are made : 1. There should be no sale or exchange of animals affected with tuberculosis except for immediate slaughter or for breeding purposes under official super- vision. 2. That the managments of live-stock shows should give preference to cat- tle known to be free from tuberculosis, either by providing special classes for such cattle or in some other practical way, and should also take every pre- caution to prevent contact between such animals and those not known to be free from disease. 3. All live-stock shippers should take every precaution to see that cars fur- nished are thoroughly cleansed and disinfected before use. Resolution 2. — Tuberculin test. 1. That tuberculin, properly used, is an accurate and reliable diagnostic agent for the detection of active tuberculosis. 2. That tuberculin may not produce a reaction under the following conditions : (a) When the disease is in a period of incubation. (b) When the progress of the disease is arrested. (c) When the disease is extensively generalized. The last condition is relatively rare and may usually be detected by physical examination. 3. On account of the period of incubation and the fact that arrested cases may sooner or later become active, all exposed animals should be retested at intervals of six months to one year. 4. That the tuberculin test should not be applied to any animal having a temperature higher than normal. 5. That any animal having given one distinct reaction to tuberculin should thereafter be regarded as tuberculous. 6. That the subcutaneous injection of tuberculin is the only method of using tuberculin for the detection of tuberculosis in cattle which can be recommended at the present time. 7. That tuberculin has no injurious effect on healthy cattle. Resolution 3. — Evidence from tuberculin test. That a positive reaction to tuberculin in any properly conducted test, official or otherwise, in any animal in any herd shall be considered evidence sufficient upon which to declare the herd to be infected. Resolution 4. — Compulsory notification. That this commission recommends the passage of legislation providing for the compulsory notification by owners and by veterinarians of the existence of tuberculosis in a herd, whether such existence be made known by detection of clinical cases or by the tuberculin test. Resolution 5. — Location through slaughter. This commission recognizes that the discovery of tuberculosis in animals slaughtered for food purposes furnishes one of the best possible means of locating the disease on the farm, and therefore recommends the adoption of some system of marking, for purposes of identification, all cattle 3 years old and over shipped for slaughter. THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 409 As tuberculosis of hogs is almost invariably due to bovine infection, this recommendation should also be made to apply to hogs of any age shipped for slaughter. It is further recommended that the discovery of tuberculosis in animals coming under Government inspection should be used whenever identification is possible as a means of locating infected herds and premises. All such cases should be reported to the proper authorities for control action. Resolution 6. — Disposition of tuherculous animals — The convniission plan. 1. As a general policy in the eradication of tuberculosis the separation of healthy and diseased animals and the construction of a healthy herd are recommended. In order to accomplish this the following recommendations are made: (1) If the herd is found to be extensively infected, as shown by the tubercu- lin test or clinical examination, even the apparently healthy animals in it should be regarded with suspicion until they have been separated from the reacting animals for at least three months. If, after the expiration of this time, they do not react to the tuberculin test, they may be considered healthy and dealt with accordingly. It is recommended that a herd extensively infected should not be treated by the method of general separation, but that the construction of a new herd from the offspring only is advisable. (2) If the herd is found, by either or both of the above methods, to contain a relatively small proportion of diseased animals separation of the diseased animals from the healthy animals and the construction of a sound herd from the healthy animals, and the offspring of both, is advocated. As a working basis in carrying out these principles, we advise : (a) That herds containing 50 per cent or more of diseased animals be treated as coming under section 1. (&) That herds containing under 15 per cent of diseased animals be treated as coming under section 2. (c) That herds falling between these figures be graded according to the option of the owner. (d) That it shall be the prerogative of the owner to reject either plan and have his herd dealt with by removal and slaughter of diseased animals, with or without compensation, according to the public policy in operation. 2. That when by any means the officials properly charged with the control of tuberculosis become aware of its existence in a herd to which a policy of slaughter and compensation can not reasonably be applied, such herd must be dealt with by the owner, under Government supervision, on the principle of the separation of all sound animals from those affected. Such separation must be effected by treating the whole herd as diseased, and rearing the calves sepa- rately, either on pasteurized milk or the milk of healthy cows, or, when the number of those affected is so small as to warrant such a course, by the appli- cation to the whole h^rd, from time to time, under official supervision, of the tuberculin test, and the entire segregation of all animals found to react. In the event of any owner refusing or neglecting to adopt either of the above methods, his entire herd to be closely quarantined and sales therefrom to be entirely prohibited. 3. That a policy of compensation be recommended as useful and usually necessary as a temporary measure. 4. That, when slaughter is necessary, in order to avoid economic loss, every effort should be made to utilize as far as possible the meat of such animals as may be found fit for food, on being slaughtered under competent inspection. 5. The details of commission plan will be found fully set forth in the ap- pendix to this report. Resolution 7. — Prevention. 1, That, with the object of preventing the spread of infection, persons buying cattle for breeding purposes or milk production should, except when such pur- chases are made from disease-free herds which have been tested by a properly qualified person, purchase only subject to the tuberculin test. In order to assist in the proper carrying out of this suggestion the commission recom- mends that official authorities should adopt such regulations as will prevent the ©Qtry to their respective territories of cattle for breeding purposes or milk production unless accompanied by satisfactory tuberculin-test charts. 410 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 2. That all milk and milk by-products used as food should be properly pae* teurized unless derived from cows known to be free from tuberculosis. Resolution 8. — Control of tuberculin test. That this commission recommends the passage of legislation which will pre- vent the sale, distribution, or use of tuberculin by any persons other than those acting with the full knowledge or under the direction of official authorities. Resolution 9. — Education, As a clear knowledge of the cause and character of tuberculosis among ani- mals, the modes of dissemination and its significance as an economic and as a public-health problem underlie an intelligent adherence to the principles that must be observed in all efforts for eradication, as well as the establishment of proper cooperation in the great work between physicians, veterinarians, live- stock owners, legislators, and the public generally, it is recommended that a widespread campaign of education be undertaken. To accomplish this end it is recommended that first of all a simple pamphlet on bovine tuberculosis be written, in which the language used shall be of such character that every person of average intelligence shall be able to read it without being mystified by technical terms or phrases. This pamphlet should be published with the indorsement of the American Veterinary Medical Association and the special indorsement and consequent authority of the International Commission on Bovine Tuberculosis Control. Resolution 10. — PuUicity. In concluding its work the commission desires especially to appeal to the press — metropolitan, agricultural, and local — to join in the work of extending as much as possible among the people the conclusions here arrived at. The vital importance of the life of farm animals to the welfare of all classes of society needs no argument in its support. The aim and sole purpose which has actu- ated this commission has been to arrive at the soundest conclusions possible in the light of the best knowledge obtainable. Resolution 11. — Legislation. It is recommended that legislation regarding the control and eradication of tuberculosis among domestic animals be made uniform ; that the laws of the United States and Canada and other American countries for the admission into America of animals from without be made stringent and as much alike as possible; and that the laws governing the interstate and interprovincial move- ment of cattle and that between different American countries be harmonized. The laws governing interstate and interprovincial movement of cattle should be of such character that every State and every Province will be free in its eradication work from unnecessary difficulties due to the existence of the disease in other States and Provinces. Legislation is especially required to prevent the various frauds which inter- fere with the satisfactory use of tuberculin as a diagnostic agent for tubercu- losis, as well as for official supervision over all tuberculin sold to be used by veterinarians and others. Resolution 12. — Sanitation. In the eradication of tuberculosis it should be kept in mind that, in addition to protecting animals against exposure to tubercle bacilli, it is desirable to make them as resistant to infection as possible. This can be done by stabling them in clean, disinfected, and properly ventilated and lighted barns, giving them abundant clean water and nutritious food, a sufficient amount of daily exercise in the open air, and attending generally to those conditions which are well known to contribute to the health of animals. . The daily removal of manure from stables and water-tight floors and good drainage in stables are urgently recommended. Young stock particularly should be raised as hardy as possible, and should be accustomed to liberal exercise and living in the open. Resolution 13. — Immunization. That as none of the various methods for the immunization of animals against tuberculosis have passed sufficiently beyond the experimental stage the com- mission is unable to indorse any of these for practical use at the present time. THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 411 Resolution 14. — Animal tuberculosis and public health. "While the members recognize that the subject with which this commission is primarily intended to deal is the control and eradication of tuberculosis among animals as an economic problem they can not feel satisfied without declaring their recognition of the fact that tuberculosis among animals is also an im- portant public-health problem. Considered as such, the eradication of tuber- culosis among animals should have the approval and support of all those persons who are interested in curtailing human sufCering and prolonging human life. Resolution 15. — General statement. The members of the commission wish it to be clearly understood that they recognize the limitations of a report necessarily based on actual and not on theoretical conditions. They fully realize that in the event of the policy of which their recommendations form the framework, being anywhere adopted even in its entirety, much greater benefit will be derived, at least for some time, from its educative than from its executive features. The control, to say nothing of the eradication of bovine tuberculosis, is impossible of achievement, without the hearty cooperation of the men who are actually engaged in the cattle industry. In order to secure this cooperation it will doubtless be necessary in most communities to carry on an active and prolonged educational campaign. It is apparent that in the dissemination of practical and reliable information regarding the disease it will be possible to employ a very large variety of methods. Many of these methods, such as bulletins, lectures, and actual demonstrations of disease, having already been found valuable will doubtless continue to be largely used. It must not be forgotten, however, that in this, as in any other educative process, a measure of disciplinary control is essential to success. Needless to say such control can be secured only by the passage of legislation which, while clear and comprehensive, must at the same time be sufficiently conservative to avoid exciting alarm or arousing antagonism on the part of owners especially of valuable herds. The best law ever framed can be made an utter failure by stupid or inju- dicious administration, while on the other hand the most drastic legislation can be rendered acceptable, if enforced with reasonable tact and diplomacy. Provided, therefore, that these qualities, combined with integrity, thorough- ness, and determination, are available for administrative purposes the mem- bers of the commission are convinced that the enforcement of a law based on their recommendations will prove to be by far the most powerful and effective educational agency which could possibly be employed. In concluding its report the commission would suggest that the association should make such provision as may be necessary to carry on the work, either by continuing the commission as at present constituted or with such changes. in the personnel as may be considered desirable.

RESOLUTIONS ON PASTEURIZATION OF MILK ADOPTED BY THE NATIONAL ASSOCIATION FOR THE STUDY AND PREVENTION OF TUBERCULOSIS, AT ANNUAL MEETING HELD MAY 2 AND 3, 1910. 1. Resolved, That a thorough, efficient, and continuous official supervision of dairies and herds and of the milk from the dairy to the consumer is of the first Importance in securing a clean and pure milk supply, which is essential to public health. 412 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 2. Resolved, Tliat the production and handling of millv under such satis- factory sanitary conditions as to insure its complete reliability (i. e., the pro- duction of what is known as certified milk) at the present time unfortunately increases its cost to such an extent as to make the use of such milk for general consumption impracticable. 3. Resolved, That the efficient pasteurization of the general milk supply (ex- cepting certified milk) when supplementing dairy inspection and applied to milk from inspected dairies and done under official supervision is desirable for the destruction of the ordinary micro organisms of fermentation and putrefaction and as an additional protection against possible infection by typhoid fever, scarlet fever, diphtheria, tuberculosis, and possibly some other specific infectious disease. 4. Resolved, That pasteurization of milk for sale should not be permitted except under official supervision and on conditions definitely prescribed by com- petent sanitary authorities; and should not be permitted as a method for the preservation of old or dirty milk. 5. Resolved, That milk intended for infant feeding should be considered apart from that intended for general consumption ; and should be certified milk when obtainable. 6. Resolved, That in the opinion of this association it has been proven, ap- parently, that a small percentage of the cases of nonpulmonary human tuber- culosis, especially tuberculosis of the lymph nodes in children under 5 years of age, is due to infection by tubercle bacilli of bovine origin. APPENDIX AE. EESOLUTIONS ADOPTED BY BOARD OF DIRECTORS, ASSOCIATION FOR PREVEN- TION OF TUBERCULOSIS, DISTRICT OF COLUMBIA, DECEMBER 27, 1910. At a meeting of the board of directors of the Association for the Prevention of Tuberculosis, held December 27, 1910, the following resolutions, presented by Dr. George M. Kober and seconded by Mr. Emile Berliner and Dr. G. Lloyd Magruder, were unanimously adopted. Whereas it has been shown by indisputable evidence that numerous epidemics of typhoid fever, scarlet fever, diphtheria, and various throat diseases have been traced to contaminated dairy products, also that a considerable proportion of the cases of tuberculosis occurring in children under 5 years of age is the result of infection with the bovine tubercle bacillus, and that the mortality among infants fed upon cow's miik is very high : Therefore be it Resolved, That the United States Congress be requested to investigate the relation of dairy products to the public health with a view of enacting re- medial legislation ; be it also Resolved, That in the opinion of this association the tax of 10 per cent upon oleomargarine is an unjust discrimination against a wholesome article of food.

APPENDIX AI. COMMUNICATION FROM GEN. GEORGE M. STERNBERG, DATED OCTOBER 9, 1907, CONCERNING PRACTICABILITY OF SHIPPING MILK IN CANS AT LOW temperature. October 9, 1907. My Dear Dr. Magruder : While at the Jamestown Exposition as a member of the jury of awards I was especially interested in the model dairy exhibited by the Virginia Polytechnic Institute ( Blacksburg, Va. ) , under the direction of Prof. William Saunders. The milk used within the exposition grounds is all sup- plied by this dairy and all shipped from Blacksburg, which, I understand, is about 300 miles distant. This milk is pasteurized and refrigerated before being shipped, and is shipped in tin cans having a felt jacket. It is quite cold when it arrives, and, indeed, has ice in it from the refrigeration practiced before ship- ping. I was glad to know that it is quite practicable to ship milk a long dis- tance without the use of refrigerator cars, maintaining it at so low a tempera- ture that bacteria will not develop in it. I have no doubt you can obtain full information with reference to this matter by writing to Prof. Saunders, or, better still, by paying a visit to his model daii-y at the exposition. Very sincerely, yours, Geo. M. Sternberg. APPENDIX AJ. COMMUNICATION FROM CHIEF OF UNITED STATES WEATHER BUREAU, DATED DECEMBER 29, 19 06, CONCERNING THE FORMATION OF NATURAL ICE DURING WINTER SEASONS IN VICINITY OF WASHINGTON, D. C. United States Department of Agriculture, Central Office of the Weather Bureau, Washington, D. C, December 29, 1906. Dr. George L. Magruder, No. 4 Jackson Place NW., Washington, D. C. Dear Sir: In regard to the formation of natural ice in this vicinity during the winter season I beg to say that on examining the records of daily minimum temperatures in this city for the last 30 years I find but one winter, viz, that of 18S9-90, during which ice could not have been gathered from ponds in this vicinity. The winter of 1889-90 was by far the warmest that has been experi- enced in the last 50 years. The mean daily temperature for the month of January, 1890, was nearly 4° above freezing; for February, 3° above, and for December, 1889, it was 4° above. In ordinary winters there is no reason why a fair crop of ice from 4 to 8 inches in thickness can not be harvested. The tendency among farmers and others who gather their own ice is to wait until the ice attains a thickness of about 8 inches, and thus sometimes fail to gather a crop, since in warm open winters ice rarely forms a greater thickness than 3 to 4 inches. Last winter, it may be remembered, was mild and open, and there was some fear expressed of a failure in the ice crop. Notwithstanding the open season, ice formed to a thickness of 3 to 4 inches in this vicinity, and a fair crop was harvested. In order to insure a crop each year, it is imperative that an artificial pond be created if no natural one is in existence, since failure will occasionally be met if dependence for an ice supply be wholly placed upon running streams. Very truly, yours, Willis L. Moore, Chief United States Weather Bureau. 416 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA, APPENDIX AK. REPORT BY UNITED STATES CONSUL T. H. NORTON OF ADDRESS BY PROF. HEMPEL ON TREATMENT OF MILK BEFORE GERMAN ASSOCIATION OF SCIENTISTS AND PHYSICIANS. German Milk Handling. | scientific discussion of how purer product may be attained. Consul T. H. Norton, reporting from Chemnitz, says that the most important address on the protection of health at the seventy-ninth annual meeting of the German Association of Scientists and Physicians, held at Dresden in September, was that on the " Treatment of milk " by Prof. Hempel. A part of the consul's summary follows: The importance of the question in Germany is evident, for the latest sta- tistical data show that the Empire produces annually 5,020,000,000 gallons of cow's milk, valued at $405,000,000, and 15,850,000 gallons of goat's milk. Com- parison may aptly be made with Germany's annual production of pig iron, valued at $232,500,000, or her annual coal output, valued at $404,600,000. It is a serious question, in view of the brilliant successes in the field of serum-therapy, whether we should not abandon entirely the current methods of treating milk by heating, so as to destroy possible germ growth, in favor of a process based upon the introduction of protective bacterial agencies, capable of neutralizing or nullifying the action of disease germs, if present. It is, however, beyond all dispute that milk from healthy animals, collected under conditions of scrupulous cleanliness, is a better and safer food than milk which has been heated to the point at which germ life is destroyed. IMPROVEMENT IN TRANSPORTATION. Intimately connected with the attainment of the hygienic dairy ideal is the problem of the transportation of milk. The larger the size of a city, the longer must be the average haul of its milk supplies, the greater the possibilities of deterioration. Furthermore, in most German cities admirably constructed dairy stables, with every possible adjunct for cleanliness and ventilation, have been erected at great expense. Their original value and their maintenance, with the highey urban charges for labor, fodder, bedding, etc., all involve a very marked addition to the normal cost of milk produced in the country dis- tricts, and constitute a tax, levied for the purpose of delivering fresh milk with the least loss of time, to the consumer. A change to more healthful and economic methods involves the distinct or- ganization of milk traffic on the German railways on such a basis that well- cooled milk shall be transported in refrigerator cars attached to express trains. It likewise presupposes the proper agencies for the distribution, under similar temperature conditions, of such milk to consumers after reaching a city. Neither of these conditions exists as yet in Germany. The excellent arrange- ments for insuring cleanliness in urban dairies have not yet been supplemented by provision for preserving milk at a low temperature until it passes into the consumer's possession, often a half day, and even an entire day, after leaving the cow. Dr. Hempel concludes that the only satisfactory solution of the milk problem in Germany is to be reached by governmental requirements and inspection at each stage along the following lines: FUNDAMENTAL RULES. " First. Dairy cows must be absolutely free from tuberculosis and be subject to frequent examination and tests by competent inspectors. " Second. They must pass the day, when the weather permits, in the open air and in pastures. " Third. They must have an abundance of good fodder, be under good care, and be cleaned each day. " Fourth. Milking should take place in a special milking room, kept scrupu- lously clean. A milker careless about personal cleanliness would respond to the stimulus of such an environment. THE MILK SITTJATIOISr IIST THE DISTRICT OF COLUMBIA. 417 " Fifth. Udders should be carefully and thoroughly washed with pure water immediately before milking and dried with clean towels. " Sixth. Milk, as soon as collected from a cow, should be rapidly cooled to a point but little above that of freezing water. In summer ice or refrigerating apparatus must be used. In winter running cold water, in pipes or the like, can be employed for the purpose. " Seventh. Milk must be kept at this low temperature during transportation and until delivered to consumers, who then become responsible for the continu- ance of the conditions described until the liquid is required as an article of food." The address closed with a forcible plea for the installation on all railways of refrigerator cars, first, to meet the needs of the milk traffic, and, second, to facilitate the transportation, of fresh meats, fish, fruits, flowers, etc. In con- nection with this brief summary of Dr. Hempel's strong presentation of the present status of the milk problem in Germany a few comments may be made. PROBLEMS TO BE SOLVED. The question of the satisfactory transportation of milk by rail for long dis- tances has been fairly well solved in the United States, wherever milk cars, constructed after the model of those used by the well-known Walker-Gordon Co., have been introduced. Greater distances have necessarily stimulated American ingenuity to a more prompt solution of existing problems in all the phases of transportation than has been the case in Europe. From a personal examination of urban dairy management in Germany I am convinced that but little remains to be done there in the matter of cleanliness, although probably the Danish practice in this respect could serve even still better as a model. It is undeniable, however, that much missionary work must be done in the United States to bring about adequate recognition on the part of the public and its representatives of the tremendous importance of carrying out fully the new fundamental rules so clearly and succinctly enunciated by the famous German chemist. Legislative action in the United States can probably not go beyond prescribing regulations for the manner in which milk shall be collected, transported, and delivered. There still remains a serious question as to the conditions under which milk is kept before being used in households too poor to buy ice or too ignorant to use it intelligently. Especially is it important in cities and during the heated term. Philanthropic effort has endeavored to lessen dangers in this connection by furnishing sterilized milk at cost price. It is now generally recognized that other and more serious dangers may be incurred in resorting to sterilization by heat. ADVANTAGES OF FROZEN MILK. Can not Dr. Hempel's thesis be carried a step further? Why not transport and deliver milk in the frozen condition? Exhaustive experiments have shown conclusively that 'pure milk, when frozen, preserves its original properties un- changed for weeks. Frozen specimens kept for over a month in a refrigerating room showed on thawing absolutely no alteration in taste, while the fact of a considerable diminution in the number of bacteria present was clearly estab- lished. Important also is the circumstance that while frozen the cream re- mains evenly diffused throughout the solidified mass, which is not the case when milk is kept at a low temperature in the liquid state. To attain such results it is essential that pure, fresh milk, as soon as collected from an animal, should rapidly be cooled to the freezing point. Dirty and contaminated milk, as well as milk in which the lactic fermentation has begun, after being frozen curdles upon melting. To effectively meet the prevalent conditions in the tenement districts of cities or the needs of infants when carried on journeys, or even the requirements of a ship's commissariat, fresh milk could be frozen in the proper containers by submerging them in brine chilled far below the melting point of ice. When the milk has not only been frozen, but cooled still further to the temperature of the surrounding liquid, the flasks or other containers can be removed, inclosed in felt protectors, and conveyed to the consumers. Frozen milk prepared under such conditions will remain in the solid form for a day or more before the temperature of the entire mass can rise to the melting point. An analogous State is that of ice harvested and housed during a very cold season. As is 82444°— S. Doc. 863, 61-^3 21 418 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. commonly knowa, its keeping qualities are far superior to those of ice gathered during a mild winter. The economic realization of such a project would involve the establishment of small refrigerating plants in connection with dairies of some size, or of larger plants, preferably adjacent to railway stations, able to chill the com- mercial milk supply of an entire district when brought to the place of ship- ment after previously being cooled to the melting point of ice. Refrigerating cars are obviously unnecessary for the transportation of milk in this form, unless unusually long distances are to be traversed. The compara- tively small cost of freezing and chilling the milk supply of a city would be more than offset by economy in transportation, by the utilization of remote and Inexpensive pasturage, and by the removal of one of the greatest causes of in- fant mortality. APPENDIX AL. COMMUNICATION ADDRESSED TO MR. D. S. HORTON, REQUESTING INFORMA- TION CONCERNING COST OF INSTALLATION OF PLANT FOR PASTEURIZING district milk supply. December 3, 1910. Mr. D. S. HoETON, Secretary Sheffleld Farms, Slatoson Decker Co., New York City. Dear Sir : The special committee of the Washington Chamber of Commerce appointed to investigate the present milk situation in the District of Columbia desires to trespass further upon your courtesy with the request that you will kindly advise it, if practicable, of the approximate cost of the large pasteuriz- ing plant which, it is understood, has recently been installed in New York City by your company. It is wished to ascertain with some degree of accuracy, if possible, what would be the cost of a plant with sufficient capacity to pasteurize the entire milk supply of Washington City, which is understood to amount to practically 20,000 gallons per day. Of course the cost of building and, indeed, the cost of equipment may vary to some extent here as compared with New York City, but the information would at least serve as an indication of what might be expected to be the cost of a plant with that capacity installed in this city. Any indication as to the approximate cost of operating such a plant (mainte- nance and labor), if furnishable, would also be welcomed by our committee. Thanking you in advance for your courtesy, I am, Very truly, yours, , Chairman. APPENDIX AM. ClOMMUNICATION FROM MR. LOTON HORTON, GIVING ESTIMATE OF COST OF ADEQUATE PLANT FOR PASTEURIZING MILK SUPPLY FOR DISTRICT OF COLUMBIA. Sheffield Farms-Slawson Decker Co., Neio York, December 12, 1910. Mr. J. Louis Willige, Willige, Gibbs cC- Daniel, Washington, D. C. My Dear Mr. Willige : Your letter was handed to me by my son, and he stated that he had had some communications with parties in Washington on the milk question, but wished me to answer your letter. It is rather a dithcult question to answer in order to give you any really positive knowledge of what you are seeking. First, I will inform you of our ideas, and possibly it may be of some benefit to you. It is needless for me to say that I have for many j^ears advocated scientific pasteurization of milk, and to confirm my ideas I have just returned from a trip abroad, where I visited eight different countries, and there was nt.'t one city of 200,000 inhabitants that I visited, including Italy, Denmark, and Holland, where they were not pasteurizing a great portion, and in some cities practically all of the milk that they received. I am also pleased to state that THE MILK SITUATION IN THE DISTEICT OF COLUMBIA. 419 wbere pasteurization is rigidly carried out they have not been visited with the epidemic of typhoid and scarlet fever for many years, caused through milk. We are at the present time building the second largest pasteurizing plant in this city. The one now in the course of construction, which iwssibly will be done in three months longer, has a capacity of pasteurizing 100,000 quarts of milk in 6 hours and making 100 tons of ice in 24 hours, besides cooling all the milk that comes in the plant. Ice should be looked upon as more or less of a by- product that can be manufactured by large milk-pasteurizing plants and brew- eries. To carry on either you certainly have to have a certain amount of refrigeration, and you practically have to keep them going night and day. By adding more units to your refrigerating than you require for the milk business it keeps everybody employed for the 24 hours, and with all conditions favorable, ice at $1.80 per ton, delivered to the dealer, would net a plant of these conditions $1 per ton net, which will go a long way toward paying the Interest on the whole investment. Now, as to building one in Washington, I will just recommend a few things tg consider first. Be sure and get on the railroad, so that you can switch the milk and the coal and what other articles you need direct into your plant. Be sure and have plenty of good, cold water. I would recommend artesian wells. The colder the water is the less amount of refrigeration it requires to cool the milk and also lessens the expense of manufacturing ice. If you could buy a good-sized plot of ground for $50,000, it would cost you to put up the proper kind of a building $175,000, and for your machinery of all descriptions, both ice, electricity, and milk machinery, possibly $150,000. I should think with the proper machinery installed, and as Washington is a great consumer of ice, that you could make enough on your ice to pay at least 4 per cent on the whole investment, and all it would cost you for the pasteurization, particularly if you did not bottle it all, would be a very trifling sum. If I can be of any service to you, and you visit my office, I will show you the plans that we have laid down in this new operation. If you should decide to build such a plant it would be good judgment to visit several plants to get the most economical and scientific methods of handling the milk, as there can be great economics worked out by so doing with proper construction. Yours, very respectfully, Loton Hobton. APPENDIX AN. PRIVATE PASTEURIZING PLANTS IN OPERATION IN DISTRICT OF COLUMBIA.

APPENDIX AQ. REPORT OF SPECIAL COMMITTEE APPOINTED BY DISTRICT COMMISSIONERS ON DISPOSAL OF STEIAUS PASTEURIZING LABORATORY, WASHINGTON, D. C. December 7, 1910. The DiSTEiCT Commissioners. Gentlemen : The committee appointed by you " to investigate the practicabil- ity of continuing the Straus pasteurization plant," after full discussion and due deliberation, reports as follows: In our opinion the pasteurization plant established in this city through the generosity and public spirit of Mr. Nathan Straus has served a most useful purpose in presenting prominently before the public the dangers of impure and raw milk as a food, especially for infants. The present plant should, in the judgment of the committee, be continued in operation by Mr. Straus or some THE MILK SITUATION IN THE DISTRICT OP COLUMBIA. 425 other pliilanthropic agency until such time as provision may be made for fur- nishing an ample and safe supply of pasteurized and modified milk through commercial channels under the direct supervision of the District health department. In the judgment of the committee it is not practicable for the District gov- ernment to undertake the management of such plant, vehich at all events could not be done without special authority from Congress and an appropriation made for the purpose. It occurs to the committee that the proposal of Mr. Straus offers a splendid opportunity for the conduct of investigations under the Department of Agri- culture or the Public Health and Marine-Hospital Service, v^^ith a view to making a practical demonstration of the value of pasteurized and modified milk as food for infants. The authoritative settlement of this question would be of immense value not only to our community, but to the entire country. In the event that for any reason it is not possible to have the operations of the Straus Laboratory continue, it is believed by the committee that existing agencies, such as the Diet Kitchen, the Citizens' Relief Association, the Associ- ated Charities, and the Instructive Visiting Nurse Society, should be encouraged by the contribution of additional, funds to continue the splendid work which is now being done by them. The activities of these charitable agencies are being exerted not only in directing and furnishing proper food for infant feeding among the poorer classes, but also in disseminating information generally with regard to the proper care of infants. It is recognized in this connection that these agencies should exercise scrupulous care in restricting the distribution of free infant food to such families as ai-e not pecuniarily able to pay for it. The milk dispensaries now in operation under existing auspices should be gener- ously supported by the public in enlarging their existing stations, and in increas- ing the number of depots from which milk may be dispensed. The committee is impressed with the great desirability of securing prompt and adequate legislation, as recommended by the District Commissioners, for providing a clean, pure, and wholesome milk supply for the Nation's capital. Pending the enactment of such legislation, the committee strongly recommends that the District authorities insist that the inmates of foundling asylums, hos- pitals, and other charitable institutions, wholly or in part supported by public funds, be supplied with milk coming within the classifications recommended by the Washington milk conference appointed by the District Commissioners in 1907. For this purpose the health ofiicer should be required, as a result of inspection, to publish a list of dairies from which the milk supply is drawn, giving the average rating of each dairy, the chemical composition, and the bacterial content of the samples. It is understood that this information is already in the possession of the health department, but provision is not made at present for its publication. The committee avails itself of this opportunity to express its hearty approval of the recommendation recently made by the health oflicer for the appointment of a corps of six visiting nurses for the public schools, whose duty it shall be to give instruction with regard to the physical well-being of the children in their homes, and during the summer months to give special attention to the prevention of infant mortality. Respectfully submitted. George M. Sternbekg, Chairman. APPENDIX AR. BILL TO AUTHORIZE THE ACCEPTANCE BY THE UNITED STATES OF THE GIFT OF THE NATHAN STRAUS PASTEURIZED- MILK LABORATORY.

During the latter part of the summer a roof garden built on the roof of the dispensary building was opened for the use of small children, and many, ou bright days, took advantage of this auxiliary. The dispensary clinic is in charge of a physician, who is present at the dispensary daily, except Sundays and holidays, for about two hours. In May, when the work began to. get heavy, a neighborhood woman was employed to help with the children and distribute the milk. Later in the summer the need for more professional service was felt, and an arrangement was made with the Instructive Visiting Nurses' Association by which the dispensary had the entire use of the services of a nurse for three months. This nurse, in addition to helping in the clinic, visited cases needing attention outside of dispen- sary hours. Appended to this report is a copy of the constitution of the present organi- zation, the separate reports for the five months, and a copy of a circular distributed to mothers in southwest Washington, giving some simple and plain instructions in the care of infants. Would it be amiss, in closing, to strike a more personal note? The writer wishes to bear witness to and express his great appreciation of the untiring efforts of his two associates [Mrs. J. P. S. Neligh and Miss Eugenia Bray] on the original board of management of the dispensary. Without their wise counsel, their never-failing patience, and ready encour- agement in the face of adversities, and their ever willingness to take upon their own shoulders the greatest burden of the work, the dispensary could never have had an existence, the great work it is to-day doing would never have been begun, all our efforts, indeed, would have come to naught.
