A Central California meat company is recalling more than 58,000 pounds of ground beef that may contain small pieces of plastic.

The U.S. Department of Agriculture says the problem was discovered during an inspection that was prompted by customer complaints.

The recalled meat from a Central Valley Meat Company in Hanford was intended for use by the National School Lunch Program.

The products are labeled "Est. 6063A" inside the USDA Mark of Inspection.

The products were produced on April 1, 2013, and can be further identified by case code "6063A3091A" or "6063A3091B."

The products were shipped to distribution centers in Arkansas, California, Montana and Texas and were intended for use by the National School Lunch Program.
