A RANGE of beefburgers sold by supermarket giant Tesco has been found to contain horse meat, according to a study.

The FSAI (Food Safety Association Ireland) say meat with horse DNA accounted for nearly 29 per cent of the meat in Tesco's Everday Value burgers - thought to have originated from two processing plants in Ireland – Liffey Meats and Silvercrest Foods – and the Dalepak Hambleton plant in north Yorkshire.

Burgers on sale in Dunnes Stores, Lidl, Aldi and Iceland was also found to have horse DNA.

The retailers have promised they are removing all implicated batches from sale.

Prof Alan Reilly, Chief Executive said the burgers pose no risk to public health.

He added: "Consumers who have purchased any of the implicated products can return them to their retailer.

"It is not in our culture to eat horsemeat and therefore, we do not expect to find it in a burger."

Tesco issued a statement on Tuesday night apologising to customers.
