The Agriculture Minister Simon Coveney has said if there is fraudulent activity behind the horsemeat controversy, it will be fully exposed.
Simon Coveney made the remarks at a hearing of the Joint Committee on Agriculture in Leinster House this afternoon.
Burger production at two plants - Silvercrest and Rangeland - has been suspended after the detection of equine DNA.
Minister Coveney said the investigations showed that all implicated raw material ingredients are labelled as Polish products.
He says significant resources have been deployed - including the Garda Fraud Bureau - to investigate the incidents.
"Whether it's factories, processing facilities, meat traders or an original source of this meat, if there is fraudulent activity going on, it is our intention to fully expose that," he said, adding he believed the experience of the fraud squad would be very useful.
