Tyson Foods is voluntarily recalling over 132,000 pounds of chicken nuggets after customers report findings of a ‘foreign object’ in their nuggets.

U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) says the object is believed to be a hard plastic material ranging in size from 21mm in length and 6.5mm in diameter.

The explanation seems to be that the material most likely came from a round, hard plastic rod the company uses to connect a plastic transfer belt. All products do pass through a metal detector, but plastic would not be detected with this type of technology.

Five-pound bags of fully cooked chicken nuggets are one of the products Tyson is recalling. The “Best If Used By” date on the package is July 18, 2017, and the case code on the packages for this product are 2006SDL03 and 2006sdl33.

20-lb. bulk packages of Tyson’s “Spare Time” fully cooked panko nugget-shaped chicken break patty fritters with rib meat are also being recalled. These were distributed for institutional use in Pennsylvania. The production date was July 18, 2016, in addition the case code is 2006SDL03

Tyson Foods is urging consumers to avoid consumption and to either return products to the store or throw them away. At this point, no reports of adverse reactions with the products in question have been confirmed.
