Manischewitz dark chocolate coins are being recalled because they may include undeclared milk, according to the U.S. Food & Drug Administration.

The FDA says people who have an allergy or severe sensitivity to milk, run the risk of serious or life-threatening allergic reaction if they consume these products. The agency says a limited number of bags labeled as “Dark Chocolate Coins” contained milk chocolate coins, which contains milk allergen that is not declared on the label.

Only Manischewitz Dark Chocolate Coins .53 oz packages with Lot Code 2283 may potentially have gold (dairy) coins in the “dark-chocolate tagged” bag. The display box UPC is 072700200356.

The Manischewitz Dark Chocolate Coins were distributed to stores nationwide, predominately located in the New York, New Jersey and Connecticut regions, during the weeks of Sept. 26 through Nov. 28.

The FDA says there are no reported illnesses or injuries to date, but Manischewitz is asking consumers to throw out the chocolate coins and reach out to customer service for a refund.
