In this article, we discuss regulations and practical issues in the shipping of live mice and mouse tissues, including spermatozoa, embryos, ovaries, and embryonic stem cells, and review work on microbial contamination of these biological materials. The importation paperwork for cryopreserved laboratory mouse tissues and cell lines is similar to that required for live animal importation to the United States (i.e., a pro forma invoice and declaration statements). Embryo transfer recipients in rederivation programs should be held in individually ventilated cages (IVCs 1 ) until testing shows that they are free of all unwanted microorganisms, including those listed in Appendix 3 of the Federation of Laboratory Animal Science Associations (FELASA) recommendations (Nicklas et al.
