Horsemeat has been detected in frozen lasagne on sale in Germany and supermarkets have started removing the product from their shelves.
Real supermarket chain said it had withdrawn TiP frozen lasagne – the latest tainted processed food to figure in a Europe-wide scandal.
Other German retailers including Tengelmann and Rewe are now checking their processed beef products too.
The EU Commission is urging member states to conduct random tests for horsemeat.
All EU members should carry out DNA tests on processed beef for traces of horsemeat for three months from March 1, the health commissioner said on Wednesday.
