The cases involve tourists who are visiting Norway and permanent residents.
“Statistics from 2011 to 2014 show that over 70 per cent of the patients hospitalised in Norway with potentially severe poisoning have foreign origin, mainly from Asia and Eastern Europe,” says Kristin Opdal Seljetun, senior adviser at the Poisons Information Centre at the Norwegian Institute of Public Health.
Edible and poisonous mushrooms look alike
The reason may be that people from other countries have another foraging culture and they may pick mushrooms that are not considered to be edible in Norway. In addition there is a big difference between the local fungi that grow in different countries and continents.
“An edible mushroom in one country can be very difficult to distinguish from a very poisonous mushroom in Norway,” explains Seljetun.
