Third of supermarket burgers contain horsemeat

Beef burgers for sale in Irish branches of Tesco were found to contain 29% horsemeat, after the Food Safety Authority of Ireland (FSAI) did a spot-check on beef products for sale in supermarkets.

The burgers, sold as Tesco Everyday Value Beef Burgers, were also found to contain pigmeat — even though pork was not mentioned on its label.

The investigation by food safety chiefs found that nearly a third of beef burgers for sale in supermarkets contained horsemeat while 85% contained pig DNA.
