Munch has issued a recall order on its Munch Chicken and Bacon Caesar wrap due to the possible presence of "undeclared fish".

This affects the product with use by dates up to and including Saturday, July 23.

A statement from the Food Standards Agency (FSA) confirmed the recall and warned customers not to eat the product.

In a statement on its website page, it said: "If you have bought the above product and have an allergy to fish, do not eat it. Instead, dispose of or return it to the store from where it was bought."

What is a product recall?

If there is a problem with a food product that means it should not be sold, then it might be 'withdrawn' (taken off the shelves) or 'recalled' (when customers are asked to return the product).

The FSA issues Product Withdrawal Information Notices and Product Recall Information Notices to let consumers and local authorities know about problems associated with food.

In some cases, a 'Food Alert for Action' is issued.

This provides local authorities with details of specific actions to be taken on behalf of consumers.
