There’s an active recall on approximately 72,240 pounds of ready-to-eat meat products, according to the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS). This is due to a potential Listeria monocytogenes contamination.

At least 15 people have fallen sick as a result of eating contaminated ground beef, and health officials warn that the products may still be lurking in restaurant refrigerators.
