Lystn, LLC, doing business as ANSWERS Pet Food, has initiated a voluntary withdrawal of specific lots of their dog food formulas including Detailed Beef, Straight Beef, and Straight Chicken. This precautionary action follows test results by the U.S. Food and Drug Administration that revealed the presence of Salmonella and Listeria monocytogenes. Although no illnesses have been reported in connection with these lots, handling contaminated pet food can pose health risks to both pets and humans, especially if proper hygiene practices are not followed. The products in question, sold in 4lb cartons throughout the United States, should be safely discarded and surfaces sanitized accordingly. Consumers in possession of these products can contact the company for refunds and further information.
