Tesco has recalled one of its food products as it poses a risk to anyone allergic to mustard. The supermarket giant has warned customers that its 300g Celery, Fruit and Nut Salad with a use-by date of December 2, contains mustard, which is not mentioned on the label.

It said in a notice issued today: "We are recalling a specific date code of Tesco Celery and Nut Salad 300g, due to the presence of mustard in the mayonnaise element of the product. Mustard is not mentioned on the product label, which may pose a health risk to anyone with an allergy or intolerance to mustard."

Tesco urged its customers to bring the product back to a store if they had purchased it. "If you have purchased the affected date code of the above product and have an allergy or intolerance to mustard, please return it to any Tesco store for a full refund," the supermarket wrote. "No receipt is required."

The Food Standards Agency (FSA) wrote: "This means the product is a possible health risk for anyone with an allergy to mustard."

The body added that Tesco has contacted the relevant allergy support organisations, which will, in turn, tell their members about the recall. The brand has also issued a point-of-sale notice to its customers.

The FSA said: "These notices explain to customers why the product is being recalled and tell them what to do if they have bought the product."

It added: "If you have bought the above product and have an allergy to mustard, do not eat it. Instead, return it to the store from where it was bought for a full refund.

"Sometimes there will be 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"Then it might be 'withdrawn' (taken off the shelves) or 'recalled' (when customers are asked to return the product).

"Sometimes foods have to be withdrawn or recalled if there is a risk to consumers because the allergy labelling is missing or incorrect or if there is any other food allergy risk.

"When there is a food allergy risk, the FSA will issue an Allergy Alert."
