INCREASED LEVELS OF DIOXINS IN IRISH PIG MEAT;THE DUTCH CONNECTION
A very high level of dioxins in pork imported from the Netherlands and discovered in France was traced back to an incident in Ireland. The incident was, caused by the use of oil containing PCBs for drying bakery waste. Levels in pooled samples of pork varied between 3 and 138 pg TEQ/g fat, and showed a dioxin and PCB pattern that indicated a highly chlorinated PCB mixture as the source. The pattern in pork differed from the pattern in the bread crumbs due to the selective metabolism of 2,3,7,8-TCDF and 1,2,3,7,8-PCDF. The ratio between indicator-PCBs and dioxins was around 2000-4000, being 10-20x lower than observed during the Belgian incident in 1999. This made the use of indicator-PCBs as a marker virtually impossible due to the required detection limits; only highly contaminated items would be identified. The incident once again shows the need for chain wide screening of feed and food for dioxins and PCBs. Evaluation of this crisis also raises questions about the safety evaluation of products that are as contaminated as during this incident.
