Two international markets, Canada and Oman, are to take in Irish beef and sheepmeat.
In the case of Oman, Irish sheepmeat will have full access to this market, while building on the existing access it has for Canada.
The opening of the Canadian market to European Union beef is part of an EU-wide deal brokered by the European Commission.
It follows an EU-wide audit process, in which Ireland was a leading participant.
Agriculture Minister Simon Coveney said: "I am delighted to see the re-opening of this potentially valuable market in Canada".
"This is a market with strong Irish links, which appreciates premium quality foods and should be a natural fit for Irish beef. It builds on the progress in accessing the US market earlier this year".
"Our role in showcasing Irish production systems as part of the EU audit undoubtedly played a key role in securing this access".
On Oman, Mr Coveney added: "The Gulf countries are one of the fastest growing segments of our export markets and Irish beef and lamb is much sought after there".
"I am particularly pleased that sheepmeat access is secured here as pursuing markets for this sector is a particular target for us".
There will also be no restriction on the age of cattle from which beef can be exported.
