Asda has withdrawn the affected packs from sale. In addition, the company has contacted the relevant allergy support organisations, which will tell their members of the withdrawal. Notices have been displayed in stores, explaining to customers why the packs have been withdrawn. Anyone who has bought an affected pack can return it to an Asda store for a full refund without their receipt.

No other Asda products are known to be affected.

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 Then it might be 'withdrawn' (taken off the shelves) or 'recalled' (when customers are asked to return the product). Sometimes foods have to be withdrawn or recalled if there is a risk to consumers because the allergy labelling is missing or incorrect or if there is any other food allergy risk.

In such situations the Agency will issue an Allergy Alert. It is also possible to subscribe to an email alert system to receive automatic messages whenever Allergy Alerts are issued. Click on 'Get alerts' in the box at the bottom of this page to find more details.

You can get details of all the latest allergy alerts as soon as they're issued by getting the details sent as a SMS text message direct to your mobile phone.

To sign up to this free service, simply send the text message ‘START ALLERGY’ to the number 62372. To unsubscribe, just text 'STOP ALLERGY' to the same number.

You can also subscribe to our Really Simple Syndication (RSS) feed for food and allergy alerts.
