The supermarket said its own brand Cookies and Cream product contains milk which is not mentioned on the label, and could be a possible health risk for anyone with an allergy or intolerance to milk or its constituents.
The recall covers all best-before dates on 176g packs.
Customers who have bought the biscuits and have an allergy or intolerance are advised not to eat them but to return them to a Tesco store for a full refund.
