Batches of a popular chocolate snack have been urgently recalled over fears they could be dangerous to those with severe allergies.
Food safety watchdogs stuck a 'do not eat' alert on health brand Myprotein's double chocolate and caramel gooey filled cookie.
It is feared the sweet treat may contain hidden traces of wheat and pose a risk to anyone with an allergy or intolerance to gluten.
THG Nutrition Limited, which manufactures the product, said the recall affected all batches of its 75g single cookies and box of 12 cookies.
All have best before dates of between June 17, 2025 to July 16, 2026.
In a separate statement, Myprotein said: 'Out of an abundance of caution, we're voluntarily recalling the double chocolate and caramel gooey filled cookie, due to the presence of an undeclared allergen, wheat.
'If you purchased the product from one of our retail partners, please return the product or bring your receipt to the point of purchase or local store for a full refund.
'It's important to note that only a very small portion of Myprotein products are produced externally.
'The vast majority of Myprotein products are made in-house at our own state-of-the-art facilities. This ensures full control over quality and safety across our product range.
'Your safety is our top priority, and we're working closely with our manufacturing partner to understand how this happened and to make sure it doesn't happen again.'
The Food Standards Agency (FSA), which published the alert, issues recalls when problems are spotted with food that means it should not be sold.
It also said: 'If you have bought the above product and have coeliac disease, and/or an allergy or intolerance to wheat or gluten, do not eat it.'
'THG Nutrition Limited is recalling the above product from customers and has contacted the relevant allergy support organisations, which will tell their members about the recall.
'The company has also issued a recall 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.'
Coeliac disease is an autoimmune condition where sufferers cannot digest gluten. It is thought to affect around one in every 100 people.
For sufferers of coeliac disease or any other condition which makes them gluten intolerant, an allergic reaction can cause symptoms ranging from rashes to trouble breathing and even unconsciousness.
Among those who have coeliac disease, the immune system mistakes substances found inside gluten as a threat to the body and attacks them.
This damages the surface of the small bowel, disrupting the body's ability to take in nutrients from food.
It's not entirely clear what causes the immune system to act this way, but a combination of genetics and the environment appear to play a part.
