Georgia-based food producer Tip Top Poultry on Thursday expanded its recent recall of ready-to-eat chicken products to include new ones sold at places like Aldi, Kroger, and Trader Joe’s.

The products, which include frozen, diced, and shredded chicken used in sandwiches, wraps, and salads, were found in some cases to be contaminated with listeria monocytogenes. All the affected products were from the same single production line, which has since undergone a thorough cleaning.

“Tip Top Poultry is shutting down this fowl cooking line until it identifies the source of any potential contamination and completely eliminates it,” the company said in an official statement.

The initial recall was issued on Sept. 28. It was expanded after the affected chicken was found to have been used in other products and potentially served at deli counters.

The contaminated product was produced between Jan. 21 and Sept. 24. An unknown amount was shipped to retailers in the U.S. and Canada, with retailers also including Food Lion, Giant, Dillons, IGA, Piggly Wiggly, and Harris Teeter.

The affected products bear the number “Est. P-17453” inside the USDA inspection symbol. Among the products are Duke Chicken Salad, Clean Eatz Baja Pineapple Chicken, SpringGlen Fresh Foods Chunky White Meat Chicken Salad, Nutrisystem Three Cheese Chicken, Private Selection Butter chicken Spring Rolls, and Trader Joe's Chicken Pot Pie.

Consumers who have bought any of these products are encouraged to dispose of them or return them to the store immediately.
