Tens of thousands of pounds of chicken nuggets are being recalled across the US, according to the Department of Agriculture. Tyson Foods is voluntarily recalling all five-pound bags of  the “White Meat Panko Chicken Nuggets” that were produced on Nov. 26, 2018, according to the Department of Agriculture’s Food Safety and Inspection Service.

A small number of consumers contacted the company to say they had found small pieces of soft, blue rubber in the nuggets, prompting the company to issue the recall,  a Tyson Foods spokesperson said in a statement. “Though the pieces have been found in a very small number of packages, no injuries have been reported with this recall.”

However, out of an abundance of caution, the company is recalling 36,420 pounds of product, the spokesperson said.

The company first became aware of the problem on Tuesday. Authorities are now urging people to double check if they’ve purchased the nuggets.

The affected products have a use-by date of Nov. 26, 2019, and a UPC of 0 23700 03558 5.
