Booker has been forced to recall a batch of Euro Shopper Milk Chocolate due to packaging error.
The batch may contain fruit and nut chocolate which is not mentioned on the label posing a health risk to those allergic to nuts.
Retailers are urged to check for batch code L512620 100g with a best before date of April 2012 and remove them from the shelves immediately.
The Food Standards Agency has issued an allergy alert and no other Euro Shopper batch codes or products are known to be affected.
Booker has apologised for the inconvenience caused and advised retailers with stocks of this product to return it to their local branch to obtain a replacement or full refund.
