The Irish Food Safety Authority has ordered the withdrawal and recall of all Irish pork products dating back to 1 September.
It follows the discovery of the dioxin PCB in pork at levels between 80 and 200 times the safe limits.
The contamination of the pork arose following the contamination of feed for pigs.
The contamination first came to light last Monday, but the positive tests in the pork was only confirmed this afternoon.
The public have been advised to destroy all pork products
purchased since September.
It is understood that contaminated feed was used at a total of 37 farms, 29 of which were pork farms and the other eight were beef farms.
But the FSA has advised that it is not necessary at this time to have a similar withdrawal of beef products.
The Taoiseach and Minister for Agriculture Brendan Smith, have attended crisis talks at the Department of Agriculture following the discovery of the toxic substance in slaughtered pigs.
The discovery has provoked concern in the farming community.
The pork industry is the fourth biggest in the agriculture sector and is worth around EUR400 million per year.
The movement of animals at some 30 farms has been restricted.
A major investigation has been launched by the Department of Agriculture and the Food Safety Authority.
Fine Gael's spokesperson on agriculture, Michael Creed described the discovery as potentially the biggest threat to the agri-food sector since the outbreak Foot & Mouth disease.
