There are distinct differences between the regulations as they apply to veterinary pharmaceuticals, medical devices, and veterinary biologics. Veterinary product regulations in the United States are primarily regulated through three agencies, the FDA-CVM, USDA-CVB or EPA depending on how they are categorized.
Veterinary pharmaceuticals, including feeds, devices, and supplements are regulated under and/or subject to regulations per the Food and Drug Administration – Center for Veterinary Medicine (FDA-CVM).
Veterinary biologics, which include vaccines, diagnostic kits, and immune modulators are regulated by the United States Department of Agriculture – Center for Veterinary Biologics (USDA-CVB).
