SAN FRANCISCO >>California-based chicken producer Foster Farms is recalling about 6,165 pounds of its ready-to-eat grilled chicken breast strips because the strips contain wheat and soy — known allergens — which are not listed on the labels of its packages, federal agriculture officials said.

The mislabeled packages were discovered when a customer complained, the U.S. Department of Agriculture’s Food Safety and Inspection Service said in announcing the recall Tuesday.

The problem occurred when labels for another chicken product that does not contain wheat or soy were inadvertently used, food safety inspectors and officials at Foster Farms said.

There have been no reports of adverse reactions from the sale of the mislabeled products, officials said.

The chicken breast strips being recalled were sold in 4.5-pound cases containing 12, 6-ounce trays of “Foster Farms Grilled Chicken Breast Strips Boneless & Skinless With Rib Meat 97% Fat Free,” with an identifying case code of “000606.”

The recalled product bears the establishment number “P-20923” inside the USDA mark of inspection and a use-by date of “JUN 22 2013” printed on each tray.

They were produced April 23 and were distributed to retailers in Arizona, California, Hawaii, Nevada, Oregon, Utah and Washington.

Based in Porterville, Foster Farms is a family-owned company that has been operating since 1939, according to the company’s website.

In a statement, Fosters Farms spokeswoman Lorna Bush said “food safety is, and always has been, our top priority.”
