The Association of American Feed Control Officials (AAFCO) is a non-profit organization that establishes guidelines and standards for animal feed and pet food in the United States. It works with state and federal agencies to ensure that animal nutrition products are safe, effective, and labeled accurately. AAFCO does not regulate or test products itself but provides a framework for regulatory agencies to follow. AAFCO's primary role is to develop model regulations and definitions for animal feed ingredients. It also oversees the approval of pet food labels, ensuring they meet specific nutritional requirements. This helps consumers make informed choices about the food they provide for their pets.
