After multiple consumer complaints, the U.S. Department of Agriculture has issued a public health alert for some Wegmans chicken nugget products warning they may contain “extraneous material.” The frozen chicken nuggets were sold in Pennsylvania and seven other states, as well as the District of Columbia, according to a Jan. 27 notice.

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 are being recalled in Massachusetts and seven other states and the District of Columbia due to possible bone fragments.
