Determination of undesirable substances in fish and fish products
The National Institute of Nutrition and Seafood Research (NIFES) has determined the content of certain undesirable substances in marine oils for human consumption and in selected fish and fish products. The results show low levels of the contaminants in mackerel and a generally low level of dioxins and dioxin-like PCBs in oils for human consumption. Of 25 samples of eel, 12 had a level of dioxins and dioxin-like PCBs which exceeded EU’s upper limit for these substances.
