Foster Farms is recalling approximately 39,747 pounds of frozen pre-cooked chicken products from its Farmerville, Louisiana, facility due to possible contamination with Listeria monocytogenes. The recall was announced September 25 by the USDA’s Food Safety and Inspection Service (FSIS).

The frozen Chicken Breast Grilled Strips product was produced on August 5, then shipped to retail warehouse locations in the states of California, Texas, Utah, and Washington. The following product is subject to recall: 3.5-lb. Plastic resealable bags containing frozen “Chicken Breast Grilled Strips.” The affected product packaging will bear the establishment number “P-33901” as well as a Best by Date of 08-05-15.

The problem was discovered during the company’s routine in-plant inspection. While some of the product was set aside and held, the product subject to this recall was inadvertently shipped. FSIS and the company have received no reports of illnesses associated with consumption of these products.

Consumption of food contaminated with L. monocytogenes can cause listeriosis, a serious infection that primarily affects older adults, persons with weakened immune systems, and pregnant women and their newborns. Less commonly, persons outside these risk groups are affected.

Listeriosis can cause fever, muscle aches, headache, stiff neck, confusion, loss of balance and convulsions sometimes preceded by diarrhea or other gastrointestinal symptoms. An invasive infection spreads beyond the gastrointestinal tract. In pregnant women, the infection can cause miscarriages, stillbirths, premature delivery or life-threatening infection of the newborn. In addition, serious and sometimes fatal infections in older adults and persons with weakened immune systems. Listeriosis is treated with antibiotics. Persons in the higher-risk categories who experience flu-like symptoms within two months after eating contaminated food should seek medical care and tell the health care provider about eating the contaminated food.
