The Food Standards Agency has issued a warning over a Tesco Bran Flakes product because of undeclared milk and hazelnut.
The product, which is part of the supermarket's own-brand Free-From range, may contain a small amount of chocolate pillows that contain milk and hazelnut.
This makes the cereal a "possible health risk" as people with an allergy or intolerance to milk or hazelnut could unknowingly consume the product. Customers have been told that they can return the affected product to a Tesco store for a full refund, and no receipt is required.
