Knott’s Fine Food, Inc. of Paris, Tenn., has voluntarily recalled its 3-ounce Chicken Salad Sandwiches with expiration dates of 1/29/13 and earlier because they may be contaminated with Listeria monocytogenes. The recalled products were distributed to 35 retail locations in western Tennesse, western Kentucky and northern Mississippi. It comes in a 3-ounce black wedge with a clear plastic film enclosure. The UPC code is 0-11984-01132-6. All expiration dates of 1/29/13 and earlier are subject to the recall. Expiration dates are located on an orange sticker on the plastic enclosure. No illnesses have yet been reported in connection with this recall. However, due to the time it takes to trace illnesses back to a food source, it is impossible to say whether the product has caused illnesses at this time. The problem was discovered by the Tennessee Department of Agriculture during routine testing, which found one chicken salad sandwich to be contaminated with Listeria.
