Nearly £300m worth of market value has been knocked off the value of Tesco following reports that a number of its burgers were found to contain horsemeat
Tesco, along with rivals Lidl and Aldi were found to be selling burgers that contained horse DNA. Both Asda and Tesco have now cleared products off their shelves as the Food Standards Agency launched an investigation. In one Tesco product, 29 per cent of the 'beef' content was actually horsemeat. Suppliers in continental Europe are suspected of being the source of the horsemeat, a processing firm has claimed.
