LONDON (AP) -- U.K. authorities say beef lasagna products recalled from British supermarkets by frozen-food company Findus have tested positive for more than 60 percent horsemeat.
The revelation comes after millions of burgers were taken off shop shelves earlier this month as it emerged that beef products from three companies in Ireland and Britain contained horse DNA.
The U.K. Food Standards Agency said Thursday that its tests on Findus's beef lasagna were part of an ongoing investigation into mislabeled meat and that there is no evidence the results pose a food safety risk.
But it advised people not to eat the lasagna and return them to the shops they were purchased from.
Findus had recalled its beef lasagna after its French supplier, Comigel, raised concerns.
