ABSTRACT
Animal diseases are an important factor inhibiting world trade and hampering the free movement of both live animals and animal-derived products. The foot-and-mouth disease outbreak in Denmark in early 1982 provides an example of the impact of animal disease on trade. The entry procedures for animals from Mexico and Canada are generally less strict than those for animals from overseas nations because Mexico and Canada have animal disease situations relatively similar to ours. Since animal semen is as much a potential disease threat as live animals, it must be subjected to strict standards for collection, handling, and shipping. More research is needed to determine the diseases to which embryos are immune. The animal health requirements of foreign countries vary, reflecting the particular animal disease part of the world. Testing and certification are performed by private veterinarians accredited by us who normally conduct their tests on the farm or cattle ranch.
