Batches of a popular lager 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 cans of Jeremy Clarkson's brand Hawkstone products. 

It is feared two beers — Hawkstone Black and Hawkstone Spa Lager — may contain hidden traces of wheat and pose a risk to anyone with an allergy or intolerance to gluten.

The Cotswold Brewing Company, which manufactures the product, said the recall affected all batches of both products.

These include Hawkstone Black 440ml cans with the barcode 5060158980567 and Hawkstone Spa Lager 330ml Cans with the barcode 5060158980482. 

They added: 'If you have bought the above product and have an allergy or intolerance to wheat, do not consume it. 

'Instead return it to the place where purchased where a full refund will be given. 

'Customer safety is of paramount importance to The Cotswold Brewing Company Limited and we take all issues regarding the production of our products extremely seriously. 

'For more information, please contact [email protected] or call 01451 824488.' 

British safety regulator, The Food Standards Agency (FSA), which issued the alert, also said: 'The company has also 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 any of the above products and have an allergy or intolerance to wheat or gluten, or with coeliac disease, do not consume them.' 

Coeliac disease is an auto immune 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.
