The U.S. Food and Drug Administration is cautioning pet owners that samples of two Answers Pet Food products made by Lystn LLC tested positive for Salmonella, a third product tested positive for Listeria monocytogenes (L. mono), and a fourth product tested positive for Salmonella and L. mono.

The FDA collected and tested unopened retail samples of products after receiving three consumer complaints of illness in dogs that ate the products. The products are sold online and in retail locations nationwide. The FDA recommended that Answers Pet Food recall these products. To date, the firm has not initiated an adequate recall of the affected products.

The affected products are sold frozen in 4-pound (half-gallon) cartons. If consumers have any pet food on the list below, they are advised to throw it away in a secure container. Do not feed it to your pets. Do not donate the food. Clean and disinfect all pet supplies and surfaces the food or pet had contact with.
