In some Norwegian fjords, the concentration of hazardous chemicals in marine organisms are high. Eating fish or shellfish from these areas may be harmful. The Norwegian Food Safety Authority advices against the consumption of seafood from these fjords.
Advice against consumption of seafood from Norwegian fjords
Altogether the advice against consumption of seafood currently applies to about 30 Norwegian fjords. Reduced discharges of hazardous substances has improved conditions in some fjords, and in some cases it has been possible to reduce the area covered by the advice.
In other areas the levels of contaminants in fish and shellfish remain high, despite large reductions in discharges. Just a few advices have been completely lifted.
Advice against the consumption of marine fish liver
The Norwegian Food Safety Authority also advices those who fish for their own use not to eat fish liver caught close to the coast. The exception is cod that is caught in the open sea. This advice is based on surveys that show levels of dioxins and dioxin-like PCBs exceeding consumption limits in fish liver.
Advice against the consumption of fresh water fish
Due to the detection of high concentrations of mercury the Norwegian Food Safety Authority has introduced a nationwide advice against the consumption of fresh water fish. The advice concerns pike and perch larger than 25 cm. and big trout and char ( >1 kg). Pregnant women and breastfeeding mothers should avoid eating such fish. Others should not eat such fish more than once a month.
This advice concerns fish caught in rivers and lakes, and is based on several surveys of mercury in fresh water fish. Farmed fish is safe to eat, including spawning sea trout migrating from the sea to fresh water.
Advice against the consumption of scallops
Avoid eating great scallop's gland and kidneys from horse mussel. Surveys show that they contain high levels of lead and cadmium.
