Three months after elevated levels of dioxin were found in organic eggs on an organic egg farm in Münsterland, Germany the authorities have identified a potential source.
“One researcher suggests that the source of contamination is a heating system that was until about ten years ago in one of the two affected stables," reported a spokesperson for the Borken Council and confirmed reports made last week.
"This heater could have caused PCB and dioxin-containing emissions. Because in close proximity to it, between the two houses, the highest PCB levels have been reported."
The expert believed that Polychlorinated Biphenyl (PCB) contaminated oil was used for the heaters.
Eggs from the farm in Velen were voluntary inspected in mid-May and elevated levels of dioxins and dioxin-like PCBs were detected.
