The Federal Meat Inspection Act of 1906 (FMIA) is an American law that makes it illegal to adulterate or misbrand meat and meat products being sold as food, and ensures that meat and meat products are slaughtered and processed under strictly regulated sanitary conditions. These requirements also apply to imported meat products, which must be inspected under equivalent foreign standards. USDA inspection of poultry was added by the Poultry Products Inspection Act of 1957. The Food, Drug, and Cosmetic Act authorizes the FDA to provide inspection services for all livestock and poultry species not listed in the FMIA or PPIA, including venison and buffalo. The Agricultural Marketing Act authorizes the USDA to offer voluntary, fee-for-service inspection services for these same species.
