Comprehensive environmental review following the pork PCB/dioxin contamination incident in Ireland

Abstract

In December 2008 the Irish Government made a decision to recall all Irish pork and bacon products from pigs slaughtered in Ireland since September 1 2008 as a result of polychlorinated biphenyl contamination identified during routine monitoring of Irish pork products. 30 000 tonnes of returned product were subsequently destroyed, as well as 170 000 pigs and 5700 cattle, with a cost to date to the Irish exchequer in excess of €120 million, as well as reputational damage to the Irish agriculture and food industries. The source of the contamination was traced to an animal feed production facility which was using the hot gases from the combustion of contaminated fuel oil to dry animal feed. This review examines the events which led to the contamination of the feed, the associated environmental monitoring investigations that followed, and also the lessons learned from this incident.
