Perdue recalled hundreds of thousands of frozen ready-to-eat chicken breast nuggets and tenders for possible metal contamination, the Food Safety and Inspection Service said.

The affected items are the 22-ounce simply smart organics breaded chicken breast nuggets, the 29-ounce chicken breast tenders, and the 22-ounce butcherbox organic chicken breast nuggets. All of the bags have a “Best If Used By” date of March 23, 2025, FSIS, an agency of the U.S. Department of Agriculture, said in a news release on Friday.

The recall includes about 167,171 pounds of the frozen ready-to-eat products.

“FSIS is concerned that some product may be in consumers’ freezers,” the agency said. “Consumers who have purchased these products are urged not to consume them. These products should be thrown away or returned to the place of purchase.”

Perdue Foods LLC said in a news release that “a foreign material was identified in a limited number of consumer packages.” FSIS said metal was found in the products and was discovered receiving consumer complaints about metal wire embedded in the food.

“We determined the material to be a very thin strand of metal wire that was inadvertently introduced into the manufacturing process,” said Jeff Shaw, Perdue’s senior vice president of food safety and quality. “Out of an abundance of caution, we decided to voluntarily recall all of these packages of products.”

There have been no confirmed reports of illness or injury, FSIS and Perdue said.
