Amid an ongoing pet food recall, the U.S. Food and Drug Administration (FDA) is urging pet owners not to give their dogs and cats certain food products from two different brands. Both the brands, 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 issued an official withdrawal notice over the contamination. The FDA has urged Arrow Alliance, the maker of Darwin’s Natural Pet Products, to issue an official recall, though the company has yet to do so. No illnesses have been confirmed. Pet owners should check to make sure their products are not among the potentially contaminated items before feeding it to their pets, the FDA said. Neither Pet food recall 2024 In September 2024, the FDA issued notices about two different brands of pet food, urging owners not to feed it to their pets due to the risk of contamination with salmonella and listeria. The FDA announced that it discovered salmonella in five samples of raw dog food made by Darwin’s Natural Pet Products, manufactured by Arrow Reliance. A sixth sample contained both salmonella and listeria monocytogenes.  “As part of our outreach, we specifically communicated with customers who had already received product lots that were included in the FDA’s notice — about 3% of our customers nationwide. Only a limited amount of product had left our facilities, and the lots are not currently in distribution. Per our protocols, we had preemptively stopped shipping any potentially affected product lots earlier in the month, as soon as the FDA let us know it had taken samples for testing,” a spokesperson Gary Tashjian, founder and CEO of Darwin’s Natural Pet Products, tells TODAY.com in a statement in part. “Darwin’s is confident our meals are safe. As we’ve also shared with our customers, we commissioned independent, third-party testing using conventional methods, which found that all lots tested negative for listeria. The testing found small trace amounts of salmonella, which is inherent to poultry.” Meanwhile, Answers Pet Food voluntarily recalled three of its dog food products “out of an abundance of caution” when FDA samples found salmonella and listeria in several types of its food, the company said in a statement.
