AAFCO does not regulate, test, approve or certify pet foods in any way.
AAFCO establishes the nutritional standards for complete and balanced pet foods, and it is the pet food company’s responsibility to formulate their products according to the appropriate AAFCO standard.
It is the state feed control official’s responsibility in regulating pet food to ensure that the laws and rules established for the protection of companion animals and their custodians are complied with so that only unadulterated, correctly and uniformly labeled pet food products are distributed in the marketplace and a structure for orderly commerce.
