The Association of American Feed Control Officials (AAFCO) is a voluntary membership association of local, state and federal agencies. Our membership includes regulatory officials and those in the animal and pet feed industry that collaborate and communicate with one another in order to promote a safe feed supply through unified system-based regulation, feed ingredients standards and laboratory operations. AAFCO is the go-to resource for all U.S. animal feed regulatory information. We provide a forum for feed regulatory officials to come together and create model guidance to ensure that the regulation of animal feeds is as uniform as possible from state to state. Members and stakeholders collaborate to develop and provide ingredient definitions, label and feed ingredient standards and laboratory guidance in order to promote a safe feed supply. AAFCO also provides resources for the animal feed and pet food industries and feed regulatory information for livestock production farmers and ranchers, pet owners, veterinarians and other animal professionals.
