The Minister for Agriculture says the investigation into how horsemeat got into burgers made and sold here is onto something and it appears to be a labeling and tractability issue.

Simon Coveney says there is no evidence to suggest that either of the 2 plants at the centre of the burger controversy knowingly imported horsemeat.

Silvercrest Foods has suspended production until further notice.

Food labeling regulations

Mr. Coveney said yesterday that a lack of respect for proper food labeling regulations may have lead to the horse meat controversy.

More than 10-million burgers have been withdrawn from sale since the Food Safety Authority of Ireland (FSAI) announcement on Wednesday.

Minister Coveney said it is too early to assess the damage done to Irish food exports.

Minister Coveney says more test results are expected this evening and over the coming days.

He was speaking to Breakfast here on Newstalk.
