Three of the UK's biggest supermarkets are warning customers the “gluten-free” products they bought may contain gluten.
Asda, Sainsbury's and Waitrose have all issued statements recalling certain products branded as gluten-free, ranging from pitta breads to pizza bases and pancakes.
On its website, Asda said:
It has been brought to our attention that Asda Free From 4 White Pitta Bread with best before code of either 26.06.2015, 30.06.2015, 02.07.2015 & 02.07.2015 may contain gluten, making it a possible health risk to anyone who is allergic or has an intolerance to gluten.
It asks anyone who has purchased these items to return them to their nearest store, where they will be given a refund.
Sainsbury's issued a similar call, specially requesting the return of pizza bases, multiseed and white pitta breads, coriander naan breads, syrup pancakes and sultana scones.
"As a precautionary measure, we are asking all customers who have bought these products to return them to their nearest Sainsbury's store, where they will receive a full refund,” it said.
"No other Sainsbury's products are affected by this issue, and we apologise for the inconvenience this may cause."
Waitrose asked shoppers to bring back its pitta breads, scones and gluten-free pancakes, all of which are “unsuitable for anyone who is allergic or has an intolerance to gluten”.
In all three cases, the recall applies to products labelled with specific sell-by dates.
