Horse meat has now been found in beef burgers on sale in Spain, an independent consumer group in the country has reported today (29 January).
It comes after it emerged last week that burgers on sale in one UK supermarket contained up to 29% horsemeat and others small amounts.
Irish officials now claim the contaminated meat that led to the UK scare had come from Poland.
Irish agriculture minister Simon Coveney announced the results of further testing by his department on Saturday (26 January).
The ABP Food Group — the company at the centre of the scare — has welcomed the news that the meat had come from a “third party continental supplier”.
And it denied rumours that the company’s Polish plant was responsible for the contaminated meat.
“We are relieved that the source of the problem has been identified,” said chief executive Paul Finnerty.
“The source of the contaminated meat from Poland is not related to ABP’s plant in Poznan. As with all parts of this group the plant does not process any horse meat.”
Many British food businesses have been affected by the scare, including Tesco, Waitrose and Burger King.
