Readers of a certain vintage might remember that almost 40 years ago Irish Meat Packers (IMP) finally decided to exit beef processing. The decision was hardly a surprise to farmers; the business had been struggling for years.IMP was a co-op, an arm of Cork Marts, and the decision was a serious reputational blow to the co-op movement, still reeling from the collapse of the other farmer-owned meat processor, Clover Meats, in 1984.
