Sainsbury's, the UK retailer, has issued its third product recall in a week with the announcement of a labelling error on its own-brand mushroom risotto.

According to an alert from the UK's Food Standards Agency, the product contains wheat gluten and chicken that were not included in the ingredients list.

The error means that the product could be a health risk to those with an allergy to wheat or those who are gluten intolerant, the FSA said.

The 400g packs of Sainsbury's Italian Mushroom Risotto being recalled have use-by dates of up to an including 14 September 2008.

The recall follows two similar announcements earlier this week. Sainsbury's recalled some of its Taste the Difference Steak and Ale pie because it contained celery, which was not mentioned on the ingredients list.

Earlier this week, Sainsbury's recalled an own-label confectionery product after pieces of metal were found in a batch.
