This was the message from Teagasc Director, Professor Gerry Boyle. He said this while speaking at a recent address to the Seanad Committee on the Brexit debacle.
Mr. Boyle says the feedstuff supply chain is in line to take the biggest hit as the main port for feed importation lies across the border in Derry.
Gerry Boyle, pictured right centre above, also added that the main imports of dairy produce usually make their way across the border from the North. This is so products like raw milk can be processed further.
Mr. Boyle also noted that many farmers living on the border still rely on meat processors north of the border, especially in the pig industry.
Teagasc estimate that Brexit could eventually lead to income reductions of up to 35% in the cattle sector and up to 20% in other sectors.
Teagasc economist, Dr Kevin Hanrahan, also spoke to the committee, telling them it is unclear as to which route the UK are going to take in its future agricultural policies but suggested it could go back to the old model of importing from colonies.
Both mean seemed rather pessimistic of options facing the industry post Brexit, and pointed out many ways in which we could be affected.
