As the oceans become increasingly polluted, this also affects the fish in the world’s oceans. The further up the food chain the fish are, the higher the PCB and heavy metal contamination. For example, sardines have lower levels than cod.
NORSAN oils are carefully purified from PCBs and heavy metals in Norway. Thus, the oils also show best values in this respect: Less than one fifth of the EU maximum limit and comparatively only 2% of the amounts contained in a portion (100 g) of cod.
