Elevated levels of environmental toxins have been found in perch, pike, whitefish, grayling, trout and Canadian char. According to Östersaund municipality, the levels are not acutely toxic but mean that you should not eat the fish too often. Therefore, the Urban Development Administration has proposed new dietary guidelines for these fish species, regarding fishing in Storsjön and Lillsjön. The Environment and Social Committee will decide on the new dietary guidelines at the committee meeting on 31 May.
Already in March 2021, Östersund municipality decided on dietary advice for perch and pike caught in Storsjön around Frösön and in Lillsjön. Test results then showed high levels of PFAS in perch and pike in these waters.
Östersund municipality only decides on dietary advice for the areas within the municipal boundary. Berg, Krokom and Åre municipalities decide on dietary advice in their municipalities.
