The USDA’s Food Safety and Inspection Service (FSIS) has issued a public health alert for frozen, dinosaur-shaped, ready-to-eat chicken nuggets sold at Walmart stores because they may be contaminated with unsafe levels of lead.  Guidelines from the Food and Drug Administration provide an interim reference level (IRL) for lead

Guidelines from the Food and Drug Administration provide an interim reference level (IRL) for lead of 2.2 micrograms. The amount of lead found in these nuggets could be as much as five times higher than this IRL for children.

A recall was not requested because the products are no longer available for purchase. However, FSIS is concerned that some product may still be in consumers’ freezers.

You ate them already. Sorry.
