Special dietary advice on fish consumption expanded to cover sea trout

19.5.2009

<div>Sea trout is one of the fish species covered by the so-called dioxin derogation granted to Finland and Sweden. </div>

Evira has in 2008 carried out analyses of the contaminant levels (dioxins and PCB as well as brominated fire retardants and organic tin compounds) of fish in the seven most important sea trout rivers in Finland (Rivers Kymijoki, Vantaanjoki, Kemijoki, Iijoki, Aurajoki, Tornionjoki and Merikarvianjoki).

For only one fish sample caught from River Merikarvianjoki, the levels of dioxin and PCB in sea trout were below 8 picograms WHO-TEQ per gram of fresh weight, which is the maximum level set by the EU.

The concentrations of brominated flame retardants and tin compounds used in antifouling paints were low. Lake trout was not included in the study, because the dioxin loads are clearly lower in lakes than in the sea.

According to the recommendations of the National Nutrition Council, fish should be eaten at least twice a week and different fish species should be varied. Furthermore, Evira has issued a special recommendation, that children, young persons and adults of fertile age may eat Baltic herring once or twice a month, if the herrings are larger than 17 cm in length. The same special recommendation also applies to salmon caught from the Baltic Sea.

On the basis of the before mentioned analysis results, Evira considers it appropriate to include also sea trout in the same category with salmon and large herrings. The special fish consumption recommendations will be updated accordingly.
