Answers Pet Food and Darwin’s Natural Pet Products, were found to have produced pet food that was contaminated with the bacteria salmonella and listeria, which can cause illness in pets that can then infect their owners.

ANSWERS Pet Food is voluntarily recalling several of its products due to potential salmonella and listeria exposure, according to the FDA.

The U.S. Food and Drug Administration (FDA) issued a recall of some of the Answers Pet Food products after they tested positive for Salmonella and Listeria monocytogenes (L. mono). The test of the unopened retail samples came after the administration received multiple consumer complaints of illness in dogs that ate the products.
