The best way to check for pet treat recalls is to check with the United States Food and Drug Administration. It maintains a searchable current listing of all recalled pet foods and treats on its website, fda.gov.
Some third-party websites, such as the American Veterinary Medical Association's website at avma.org, also reprint the FDA's list to help pet owners keep track of recalls. You can also sign up for recall alerts by email from websites such as DogFoodAdvisor.com. The Humane Society of the United States also includes information about recalls in its weekly email newsletter.
If you think a recall may affect your treats, check the packaging carefully to see whether the recall covers your specific lot number. If so, immediately stop feeding them to your pet and contact your veterinarian for advice. Do this even if your pet is not yet showing any symptoms. Call the manufacturer for advice as well. If you think that a treat has made your pet sick but there is no recall information, you can report it directly to the FDA through your state's Consumer Complaint Coordinator. Try to keep a sample of the treats available in case it is needed for testing, but be sure to keep it in a place where there is no chance of animals getting it.
