A California company is recalling approximately 72 pounds of tongue and blood sausage because of mislabeling and an undeclared allergen. The product contains hydrolyzed soy protein, which is not declared on the label, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced Thursday. Soy is a known allergen.

Mattern Sausage of Orange, CA. was alerted to the problem during a routine label assessment by FSIS personnel. The problem may have occurred because of a change in ingredient formulation.

No illnesses have been reported.

The recall includes 4-lb to 8-lb chubs of “MATTERN SAUSAGE TONGUE AND BLOOD SAUSAGE” with the establishment number “EST. 7696” inside the USDA mark of inspection on the package label. The product was produced on Sept. 6, 2011, and was shipped to sandwich shops near Orange, CA. 

Consumers with questions about the recall should contact the company’s president, Mike Mattern, at 714-628-9630.
