Investigations are under way to try to find out how beef burgers on sale in UK and Irish Republic supermarkets became contaminated with horsemeat.
Irish food safety officials, who carried out tests two months ago, said the products had been stocked by a number of chains including Tesco and Iceland stores in the UK.
But is eating horse meat really so bad?
One restaurant in Edinburgh has been serving it for years - the first in the UK to do so.
Speaking on The World at One, Fred Berkmiller, the chef-owner of L'Escargot Bleu, told presenter Martha Kearney that horsemeat is going down very, very well.
"We mainly do steak tartare with rump steak of horsemeat," he said.
