Irish Taoiseach Enda Kenny said the government was committed to resolving the horsemeat crisis as the scandal spread to more processors. The Republic's fraud squad has been called in to help agriculture authorities track down the source of the mislabelled meat. He said:
"This is a matter of reputation, obviously we cannot afford to have that. [...]It is a matter that needs to be sorted out and it will be sorted out."
His comments come as experts warned investigations will continue for some time. Professor Alan Reilly, whose research exposed the first case of contamination, said:
"We are no longer talking about trace amounts... We are talking about horse meat. Somebody, some place is drip-feeding horsemeat into the burger manufacturing industry. We don't know exactly where this is happening."
All checks by Irish and UK authorities have shown the contaminated or mislabelled meat has come from Poland, either directly, or through traders in the UK or one trader in Ireland.
