Jennie-O Turkey Store, a Hormel Foods Corp. subsidiary, is recalling about 54,960 pounds of frozen raw turkey burgers believed to be contaminated with Salmonella.

The U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced the recall Friday after 12 people were diagnosed with an illness caused by Salmonella.

Since December, people in Arizona, California, Colorado, Georgia, Illinois, Mississippi, Missouri, Ohio, Washington, and Wisconsin have been diagnosed with Salmonella Hadar infection.

An FSIS investigation linked the illnesses with Jennie-O Turkey Burgers and multiple patients reported eating the products before becoming sick.

Hormel is recalling 4-pound boxes of Jennie-O’s “All Natural Lean White Meat” turkey burgers bought at Sam’s Club stores. The recalled burgers have a use-by-date of Dec. 23, 2011, and include identifying codes of 32710 through 32780. The boxes contain a dozen individually wrapped burgers.

The turkey burgers can be returned to Sam’s Club for a full refund, according to www.hormelfoodsproductrecall.com.
