This legislation, known as the Captive Primate Safety Act , amends the Lacey Act Amendments of 1981 to regulate activities involving nonhuman primates. It establishes a new definition for "prohibited primate species," encompassing all live nonhuman primates, including chimpanzees, gorillas, monkeys, and their hybrids. The Act makes it unlawful to import, export, transport, sell, acquire, breed, or possess these species in interstate or foreign commerce. However, the bill includes specific exceptions for entities such as zoos, wildlife sanctuaries, and registered research facilities. Individuals may also retain possession of animals born before the Act's enactment if they register them with the U.S. Fish and Wildlife Service within 180 days, refrain from breeding or selling them, and prevent direct public contact. The Secretary of the Interior is mandated to issue implementing regulations within 180 days of the Act's passage.
