Valley Meat Company, a Modesto, Calif. establishment, is recalling approximately one million pounds of frozen ground beef patties and bulk ground beef products that may be contaminated with E. coli O157:H7, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced this morning.

The products subject to recall bear the establishment number "EST. 8268" inside the USDA mark of inspection as well as a production code of 25709 through 01210. These products were produced between the dates of Oct. 2, 2009 through Jan. 12, 2010 and were distributed to retail outlets and institutional foodservice providers in California, Texas, Oregon, Arizona and internationally.

FSIS became aware of the problem on July 15 when the agency was notified by the California Department of Public Health (CDPH) of a small E. coli O157:H7 cluster of illnesses with a rare strain as determined by PFGE subtyping. A total of six patients with illness onset dates between April 8 and June 18, 2010 were reported at that time. After further review, CDPH added another patient from February to the case count, bringing the count to seven. FSIS is continuing to work with the CDPH and the company on the investigation. Anyone with signs or symptoms of foodborne illness should contact a health care provider.
