Tyson Foods is recalling nearly 15 tons of dinosaur-shaped chicken nuggets after customers reported finding metal pieces in the product.

According to The Guardian one individual in the U.S. is said to have suffered a minor mouth injury after eating the Fun Nuggets.

Tyson said November 4 that it was recalling 29,819lb (14.88 tons) of the Fun Nuggets “out of an abundance of caution. The Fun Nuggets being recalled were produced at one U.S. facility and shipped to distributors in nine U.S. states, including California, Illinois, Michigan and Ohio. They carry a “best if used by” date of September 4, 2024.

The U.S. Department of Agriculture’s Food Safety and Inspection Service said the problem was discovered after the company notified it that there had been consumer complaints reporting small metal pieces in the product.

This is not the first time Tyson has had to do a product recall for its meat products.

In November 2022 the company recalled 46 tonnes of raw ground beef products after customers reported finding “reflective mirror-like material” in the meat. In early 2019 the company recalled some of its chicken nuggets after consumers said they had come across small pieces of soft, blue rubber in them.
