Wild mushroom foraging is pretty common in Eastern Europe. Warnings about it in elementary school was why I was scared of eating mushrooms for a decade (admittedly a rather childish overreaction ;). Every few years I will hear about someone getting severely ill. Context: growing up in Bulgaria in the 90s and 00s.
in other words something like 30% of population goes foraging for mushrooms at least once a year and once a year someone dies. It's so rare that they write about it in the newspaper
