Sainsbury's has issued a recall over health concerns with one of its products.

The supermarket giant is recalling its Taste The Difference Pesto Swirled Houmous because it contains milk which is not mentioned on the label.

The undeclared milk means the product is a potential health risk for anyone with an allergy or intolerance to milk.

This recall impacts the 200g pack size of the houmous, with use by dates of April 20, 22 and 23.

A spokesman for the Food Standards Agency (FSA) said: “Sainsbury’s is recalling the above product from customers and have been advised to contact the relevant allergy support organisations, which will tell their members about the recall.

“The company has issued a point-of-sale notice to its customers. These notices explain to customers why the product is being recalled and tell them what to do if they have bought the product.

“If you have bought the above product and have an allergy or intolerance to milk or milk constituents do not eat it. Instead return it to the store from where it was bought for a full refund.”

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If there is a problem with a food product that means it should not be sold, then it might be 'withdrawn' (taken off the shelves) or 'recalled' (when customers are asked to return the product).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