"It is the first time that king crabs in Norway have been analyzed for undesirable substances in such a large scale," said Mette Kristin Lorentzen, FSA.
Around 230 crabs from 23 different positions in the Barents Sea were investigated. Legs and claws were examined for both heavy metals and organic pollutants, and the results showed low levels.
"All samples were below the limits set and it shows that it is safe to eat," said Ms Lorentzen.
NIFES also examined ten different marine oils for heavy metals, organic pollutants and Salmonella. The oils that were examined included six samples of fish oil, three samples of seal oil and one sample of krill oil.
"All were below the EU limits for dioxins and dioxin-like PCBs and Salmonella was also not detected, showing that the oils are safe," said Ms Lorentzen.
