Calories are no longer the only concern when it comes to consuming chicken nuggets. As CNN reports, Tyson Foods has recalled more than 36,000 pounds of its White Meat Panko Chicken Nuggets because they might contain rubber.

The 5-pound packages of frozen chicken nuggets may have been "contaminated with extraneous materials, specifically rubber," the Department of Agriculture's Food Safety and Inspection Service (FSIS) said yesterday. Tyson discovered the issue after receiving complaints from "a small number of consumers" who found soft, blue rubber in their food, the company said in a statement. Although the FSIS classifies the health risk as "high," there have been no confirmed reports of illness or injury yet.

The chicken nuggets that are subject to the recall were produced on November 26, 2018, and shipped to stores across the country. The affected packages bear the numbers "P-13556" and "3308SDL03" above a "best if used by" date of November 26, 2019. If you have a bag in your freezer, the FSIS recommends throwing them out or returning them to the store where you purchased them. You can also cut out the UPC and date code from the package and mail it to Tyson for a full refund.
