The ham salads contain Newly Weds Foods breadcrumb products, which have been recalled by the Food and Drug Administration out of concern they may be contaminated with listeria monocytogenes.

A popular ham salad has been recalled. This recall was confirmed on Sunday, and stems from concerns that the products in question might be contaminated.

The U.S. Department of Agriculture’s Food Safety and Inspection Service issued a public health warning for Reser’s Fine Foods Ham Salad and Molly’s Kitchen Ham Salad over listeria contamination fears.
