The nuggets included in the alert were sold in Pennsylvania, Delaware, Maryland, Massachusetts, New Jersey, New York, North Carolina, Pennsylvania, Virginia, and Washington, D.C.

The chicken nuggets “may be contaminated with extraneous material, specifically bone fragments,” the U.S. Department of Agriculture says.

The U.S. Department of Agriculture Food and Safety Inspection Service (FSIS) is issuing a nationwide warning for frozen chicken nuggets sold at Wegman’s after bone fragments were found in the products.
