Authorities have issued a public health alert for a frozen chicken product sold nationwide, over concerns it could contain lead.

Officials have warned dinosaur-shaped nuggets, part of Walmart’s Great Value range, could contain five times the amount of lead set as the interim reference level for children, though no amount is considered safe.

The affected product is labelled “Great Value Fully Cooked Dino Shaped Chicken Breast Nuggets,” the U.S. Department of Agriculture’s Food Safety and Inspection Service said in a statement.

The FSIS says that the chicken nuggets subject to the public health alert have a “best if used by” date of February 10, 2027.

Also, the 29-ounce bags affected by the warning are stamped with a lot code reading “0416DPO1215” and an establishment number of “P44164.”

The nuggets were produced on February 10, 2026, according to the FSIS.

The agency added that it is continuing to investigate the alleged contamination, which was spotted during a routine surveillance sampling carried out by a state partner.

The products have not been recalled as they have been taken off the market. However, the FSIS has urged shoppers not to consume the nuggets.

Instead, the statement advises that consumers should throw the product away or return it at the point of purchase.

A Walmart spokesperson told The Independent that the company is working with a supplier to investigate the issue.

“Health and safety are always a top priority,” the spokesperson said. “As soon as we were alerted to the issue, we moved quickly to issue a sales restriction and remove the product from sale in stores and online.

“We’re working with the supplier to investigate,” the spokesperson continued. “Customers who purchased the impacted items can return to any Walmart for a refund.”

Lead can be especially dangerous for infants, young children and pregnant women as it can harm developing brains and nervous systems, the FSIS said.

Exposure can lead to learning and behavior problems, as well as slowed growth and development in children. That can cause youngsters to have a lower IQ, a decreased ability to pay attention and underperformance in school.

Parents are advised to contact their healthcare provider if they suspect their child might have been exposed to lead, the CDC says.

In its statement, the FSIS urged families to check its public health alert frequently as more products could be added to the warning.
