More than 4.5 million pounds of chicken has been recalled.
According to the United States Department of Agriculture, Pilgrim's Pride, the nation's largest chicken producer, is recalling the chicken because it might be contaminated with "extraneous materials" including plastic, wood, rubber and metal.
The products — sold under Gold Kist Farms, Pierce and Sweet Georgia brands — include 10-, 20- and 30-pound bags of chicken nuggets, patties, breakfast patties, tenderloins and popcorn-style products.
The USDA said the problem was discovered after customers found plastic in bags of chicken nuggets. The Food Safety and Inspection Service investigated and found more affected products.
So far, no injuries have been reported, but customers shouldn't eat the potentially tainted products.
