Central Valley Meat Company in Hanford, Calif., is recalling more than 58,000 pounds of ground beef that may contain small pieces of plastic.
Products affected by the recall include 40-pound cases containing 10-pound chubs of "Fine Ground Beef" with the establishment number "Est. 6063A" inside the USDA Mark of Inspection. The products can be further identified by case code "6063A3091A" or "6063A3091B." The products were produced April 1, 2013.
The U.S. Department of Agriculture made the discovery during an inspection that was prompted by customer complaints.
There have been no reports of illnesses or injuries linked to the recalled meat.
The Los Angeles Unified School District is not affected by the recall. Long Beach Unified School District says all products were checked after the USDA sent them an alert, and they do not have the recalled product.
The meat was shipped to distribution centers in Arkansas, California, Montana and Texas.
