A listeria food poisoning outbreak that has killed three people and led to one pregnancy loss is linked to newly recalled heat-and-eat chicken fettucine alfredo products sold at Kroger and Walmart stores.

The chicken dishes could be linked to a possible outbreak strain of listeria associated with three deaths and one fetal loss.

The U.S. Department of Agriculture said Tuesday that FreshRealm is recalling chicken Alfredo products that may be tainted with Listeria monocytogenes. All products made before Tuesday are affected.
