Horse meat found in Tesco burgers - North Lincolnshire stores withdraw them from the shelves
Supermarket chain Tesco, which has stores in Scunthorpe, Brigg, Ashby and Barton, has withdrawn burgers from shelves after it emerged they contained horse meat.
Tests showed that its Value burger actually contains 29 per cent horse meat.
Tesco has apologised and said it has withdrawn the burgers from its shelves.
The discovery was made by an Irish food safety expert, with the highest level of horse meat found in the Everyday Value beefburgers.
The affected burgers were made at two sites in Ireland and one in North Yorkshire.
Burgers from Aldi and Lidl also tested positive, but Aldi has said its products are only available in Ireland.
Whilst not being illegal to buy or sell horse meat, not declaring every ingredient on a food label can lead to prosecution.
