The Food Safety and Inspection Service’s main worry is that consumers may have bags of the nuggets in their freezers and will not be aware that the packages were included in the recall.

“Consumers who have purchased these products are urged not to consume them,” the agency said. “These products should be thrown away or returned to the place of purchase.”

I’m a chicken nugget enthusiast, and this news disturbs me. Which ones should I avoid?

The Tyson nuggets, labeled Tyson White Meat Panko Chicken Nuggets, were produced on Nov. 26; have a “best if used by date” of Nov. 26, 2019; and were being sold at club stores nationwide in five-pound bags. Before that, the packages had been shipped to club store distribution centers in Arizona, California, Illinois, New Jersey and Utah. The packages being recalled have “P13556” inside their U.S.D.A. mark of inspection.

In total, Tyson is recalling more than 7,200 bags of chicken nuggets across the country. The list of where its packages were distributed will be posted on the Food Safety and Inspection Service website when available.
