Swiss supermarket chain Coop has found horsemeat in its own-brand lasagne, which was supplied by Comigel - the French food supplier at the heart of the scandal in Britain.
Growing revelations about the use of horsemeat in products labelled beef have raised questions about the safety of the European food supply chain and prompted governments to send out a European Union-wide alert.
Switzerland's Coop had already withdrawn the suspect lasagne from its freezers earlier in the week for tests, which confirmed today the products contained horse meat.
The news comes as Germany announced it was investigating a consignment of beef lasagne sent from Luxembourg to an unnamed retailer in North Rhine-Westphalia on suspicion it might contain horsemeat.
The EU is urging member states to carry out tens of thousands of tests in the wake of the horsemeat scandal - but who will foot the bill?
Romanians are smarting at accusations that abattoirs there put horsemeat into the food chain.
Poland's deputy chief veterinary officer says his investigation shows the country's meat products are "genuine beef" and alleges fraud.
