Increase in mushroom poisoning cases reported in Norway as inquiries surge

This year has seen a notable increase in mushroom poisoning cases, with 14 severe incidents reported so far, according to Poison Information. A significant number of these cases involve the highly toxic “spiss giftslørsopp” (death cap mushroom), which can harm the kidneys. There has been a surge in inquiries about mushrooms, with 464 individuals reaching out for advice in September alone.

Christian Haga, a senior advisor at Poison Information, emphasized the importance of educating oneself about mushrooms before foraging. In the past decade, the average annual cases of moderate to severe mushroom poisoning stood at nine, but already this year, 14 cases have been recorded—with the mushroom picking season still ongoing.

Haga noted that many of the calls received involve concerns about the dangerous death cap mushroom, which has been commonly found this year, often growing alongside popular edible mushrooms like the chanterelle. He pointed out that many inquiries stem from confusion between these types.

With September not yet over, inquiries have already surpassed last year’s figures, which amounted to 431 for the entire month. Haga forecasts a record high for this year, anticipating that more inquiries will continue to pour in.

The lack of knowledge about local mushrooms appears to make individuals from multicultural backgrounds particularly susceptible to poisoning. One of the most concerning mushrooms is the toxic white fly agaric, which can easily be mistaken for edible varieties found in other countries. Haga expressed concern for those who pick mushrooms without adequate knowledge, urging better understanding of this seasonal activity to prevent further incidents.
