Reser’s Fine Foods of Beaverton, Ore. is voluntarily recalling some refrigerated ready-to-eat products that could have been available to customers at Walmart.

The company reports the products were distributed nationwide and Walmart was one of the recipients that may have received foods contaminated with Listeria, an organism that can cause serious and sometimes fatal illness in children, the elderly or those with weakened immune systems.

According to the U.S. Food and Drug Administration, there are no confirmed illnesses associated with these products that were manufactured at the Topeka manufacturing facility and the recall is a voluntary action.

Consumers who purchased the products make take them back to the store for a refund, or simply discard the products.

The packages will be marked with a use-by date and followed by the plant identifier code “20.”

Some of the Reser’s products sold to Walmart include: Amish macaroni salad, mustard potato salad, redskin potato salad, regular potato salad, cole slaw, baked beans, jalapeno Marketside dip, spinach and artichoke Marketside dip and tuna salad.
