Association of American Feed Control Officials

The US body whose nutrient profiles decide what a pet food may call itself complete — it writes the model rules, it does not test or approve foods.

AAFCO is a voluntary association of state and federal feed regulators. It publishes nutrient profiles and model label rules that most US states adopt into law, which is how a phrase like "formulated to meet AAFCO nutrient profiles" ends up on a bag.

What that phrase does not mean is that AAFCO looked at the food. There is no AAFCO approval, no AAFCO seal, and no AAFCO laboratory. The claim is the manufacturer's, made against a published standard. The stronger version of the claim is the one that says the food passed a feeding trial rather than being formulated on paper — worth reading for, because it appears in the same small print.
