More than 18 tons of cooked chicken prepared a little over a week ago are being recalled by a Georgia company because they may be contaminated with listeria. The US Agriculture Department says the potential problem was discovered when a private laboratory reported a positive result for listeria monocytogenes on Wednesday. The food was sent to warehouses in Georgia and Arkansas, and some could have gone to retailers. The recall, by K-D Acquisitions One Braselton, covers 14 pound boxes of "Tyson, Fully Cooked Chicken Breast Filet Fritters with Rib Meat, 3806" and 20-pound boxes of "Spare Time, Fully Cooked, Chicken Breast Fillet Fritters with Rib Meat, 3806." No Tyson Foods plant produced the recalled chicken. The chicken was produced on July 13th.
