The US Food and Drug Administration has said that pet food manufacturers are not required to prove that their pet food products are safe for human consumption.

Pet food is a huge consumer market, and the FDA’s guidance was issued in response to a complaint filed by PetSmart in September.

The complaint said that the company violated the Food, Drug and Cosmetic Act by selling food containing ingredients that could be harmful to humans.

The FDA said in its statement that it will take enforcement action against PetSmart if it fails to follow the rules of the agency.

PetSmart said that it was reviewing the guidance and could take further action.

Pet foods are marketed in many different forms, including packaged meals, ready-to-eat meals, and frozen foods.

Some of the most popular pet food companies, including PetSmart, Kelloggs, and Nestle, also make dog and cat foods.
