Hamburger patties sent to schools throughout the country are being recalled due to a "possible foreign matter contamination."

The USDA's Food Safety and Inspection Service has issued a recall on over 20,000-lbs of ready to eat beef patties from AdvancePierre Foods, Inc. that were produced on November 30, 2018.

The patties may contain a foreign matter, specifically a soft purple plastic.

According to the FSIS' recall, the contamination was brought to their attention just this week after several complaints of purple plastic in the product came from two separate consumers.

Now officials are concerned about other packages of the patties that may still be in freezers at schools across the country.

The potentially contaminated beef came in 14.06-lb. cases containing three bags with 30 pieces for a total of 90 portions of “CN FULLY COOKED FLAMEBROILED BEEF PATTIES CARAMEL COLOR ADDED” with case code 155-525-0 and package code 8334.

The products also bear establishment number “EST. 2260E” inside the USDA mark of inspection.

And while the patties were distributed to schools, it resulted from a commercial sale and was not part of food provided by the USDA for the National School Lunch Program.

No injuries or illnesses have been reported in connection with this recall, but the shipments of patties were sent to schools nationwide, so any school that thinks they may have been affected should take measures to remove the meat immediately.

The FSIS recommends discarding all affected beef patties and contacting your healthcare provider if you think you have consumed any of the recalled meat.
