ANSWER: In the United States, the AAFCO (Association of American Feed Control Officials) approves which ingredients may go into pet foods. They also approve the amount of each ingredient. The FDA regulates the processes and sanitation for pet food production. It is up to the FDA to inspect facilities and test for dangers. For more information visit their sites at www.aafco.org and www.fda.gov. It is important to note, however, that there are some loopholes for producers, and many times the FDA does not test facilities until after a problem arises. That is why many pet food companies monitor their own production.
