Former Bord Bia ceo Aidan Cotter has been appointed chairman of the new Slaney Foods and Irish Country Meats (ICM) joint venture.
The appointment comes just three months after he stood down from his role at the State-backed food marketing agency.
The Slaney Foods and Irish Country Meats (ICM) joint venture is a 50:50 partnership between Larry Goodman's ABP Food Group and the farmer-owned Fane Valley Group. The JV includes Slaney's international beef business and sheep meat specialist ICM.
The European Commission gave the deal the green light last October despite objections from the IFA and other farming organisations.
Both Slaney and ICM have stated that the new merger will not alter the day-to-day running of either company.
At Bord Bia Mr Cotter led the creation and roll-out of the Origin Green campaign.
Cotter is not the first high profile food industry person to move to work in the meat processing industry on retirement in recent years.
The former Secretary General of the Department of Agriculture Tom Moran was appointed to the board of Elivia, the second largest beef processor in France, in 2015 by Dawn Meats, which acquired a 49pc stake in the firm.
