The Association of American Feed Control Officials (AAFCO)

The Association of American Feed Control Officials (AAFCO) is a 501(c)(5) membership organization of state, federal and international animal feed control officials who adhere to state and federal laws as they regulate animal feed products in the advancement of animal and public health and safety. For more than 110 years AAFCO members have cooperated on promulgating definitions for animal food ingredients that are scientifically proven to be safe for their specific animal species and intended use of an ingredient in an animal nutrition product. AAFCO develops and publishes ingredient definitions, label standards and laboratory guidance, and its annual Official Publication is relied on globally by animal food regulators and the animal nutrition industry as the authoritative guide to animal feeding ingredients approved for use in the United States.
