The European Food Safety Authority has called on the food industry to further minimise non-dioxin-like polychlorinated biphenyls (NDL-PCBs) in food, because of health concerns about excess contamination.

A new comprehensive report on the problem notes that unlike with dioxin-like PCBs, the levels of non-dioxin-like PCBs have been lightly researched.

Although PCB production and use has been banned in the industrialised world since the late 1980's, their durability and improper disposal helps them enter the food chain. EFSA said it was hard to separate dioxin-like and non dioxin-like PCBs in the body, but warned some European consumers "may be exposed to considerably higher average intakes".
