An Ohio company is recalling one lot of its trademark crustless sandwiches because they may be contaminated with Listeria monocytogenes.

Pierre Foods of Cincinnati announced the voluntary recall of one lot — 320 cases — of Pierre™ pb jamwich, crustless peanut butter and strawberry jam sandwiches after Listeria monocytogenes was detected in one product sample.

Following discussions with the U.S. Food and Drug Administration, Pierre Foods  said it elected to recall the product to ensure consumer safety. It said the plant where the product was manufactured has operated for 19 years with no food safety recalls or other serious problems.

There have been no reported illnesses associated with the sandwiches.

The sandwiches, which are sold in a 12-count red carton in the freezer section of grocery stores. were distributed to Giant-Carlisle stores in Maryland, Pennsylvania, Virginia and West Virginia. The product is stamped “Best if purchased by 03-11-2011” in the lower right hand corner. The UPC code is 7599921368.

Consumers with the “Best if purchased by 03-11-2011” product in their freezer can return it to the place of purchase for a full refund. Consumers with questions may contact the company at 1-800-982-7091 from 8 a.m. to  5 p.m. EST.

Listeria monocytogenes can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.
