Poisoning in Israel – like mushrooms after the rain? A new study reveals the patterns of poisoning from wild mushrooms in our country. The main victims: children up to the age of 6, and also men. And what is the space where most poisonings occur? No, we are not talking about dense forests – but rather the lawns that we all know

If you grew up in the 80s or 90s, you probably also watched the Smurfs’ plots. This cheerful group, which faces the harassment of the evil Gargamel, lives inside a red mushroom with white dots – which has become one of the distinct symbols of the well-known children’s series. The lesser-known fact about this series (even for its devout viewers) is that the same red mushroom, which for many children around the world was depicted as a rather lovable home – is no less than a fly artist (Amanita muscaria), a poisonous mushroom – eating it can cause, among other things, severe hallucinations.
So, although this red mushroom is not found in Israel, its 3 relatives from the amaranth family are among those responsible for the worst poisonings that have occurred in our country; Now, a new study presented at the first Israeli wild mushroom conference and published soon in KKL-Junk’s “Yer” magazine and Mycology magazine – expands the existing knowledge about poisoning in Israel: among other things, the study found that about 40 percent of poisonings occur among children up to the age of 6. These figures are also disturbing because the outbreak of the corona epidemic in 2020 – there was an increase in poisoning cases in Israel.
Israeli-mushroom relations
According to a survey by the Association for Wild Mushrooms in Israel, in our country there are close to 750 known species of mushrooms: 135 species of which are good for food, about 600 are on the range between edible under certain conditions and suspected of being toxic or about which there is a lack of information, 3 species contain hallucinogens ( psychoactive substances that may cause hallucinations) and 3 species – the spring artist (Amanita verna) the owner of the fleshy “hat”, the artist of death (Amanita phalloides) its spherical and matrilineal dome Godcrimson (Lepiota brunneoincarnata) with the brown “hat” – contain toxins (from the cyclopeptide group) that inhibit the mechanism of protein production in the body, damage mainly the liver and that their consumption can cause death.
The new study, conducted by Dr. Dalia Levinson, a mycologist (mushroom researcher) from the Shamir Research Institute and the student Aviad Gaon, Dr. Alona Bikatova from Kew Gardens in England, in collaboration with Prof. Didi Benator and Dr. Yael Luria from the National Institute for Poisoning Information in the Medical District Rambam, and which was presented at the first conference on wild mushrooms in Israel, organized by the Association for Wild Mushrooms in Israel, the Israel Society for Ecology and Environmental Sciences, KKL-Junk, the Shamir Institute, Miguel – a scientific research institute in the Galilee, the Faculty of Agriculture, Food and Environment and the Tel Hai Academic College – Examine the phenomenon of poisoning from wild mushrooms in Israel.
The study shows that 2020 was a turning point in Israeli-mushroom relations: with the outbreak of the Corona epidemic, more residents went out into the nature close to their homes, and the interest in collecting wild mushrooms grew. However, along with the interest – also came the poisonings. In addition, according to Levinson, various publications on social networks – by picking guides as well as by independent mushroom enthusiasts – have an effect on the trend in question. “The discovery of mushrooms is reminiscent of hunting, in that it arouses excitement, and also our curiosity and our sense of adventure,” she explains.
According to Levinson, the mushrooms themselves also added to the rising trend in question, because they had optimal conditions for them: in 2020 the precipitation reached us even when the weather was hot and humid – and all of this led to their increased appearance.
Toxic or non-toxic, that is the question
The new study found that in 2010-2020 there were 614 cases of poisoning from wild mushrooms. Compared to other countries, we are actually in a not bad situation: while only 0.17 percent of all inquiries about poisoning in Israel were due to eating a poisonous mushroom, in Switzerland, for example, it is 1.7 percent.
Of those 614 cases, 41 percent occurred among adults (over the age of 18), 39 percent occurred among children up to the age of 6, and 9 percent among teenagers aged 13-16. In addition, these cases were more common among men. According to Levinson, children tend to be curious and therefore they taste different things that come their way and on the ground, among others – mushrooms.
Apart from the artists and the crimson matriine who are responsible for the most serious poisonings – mushrooms of the types Sibit (Inocybe) in which there is a poison that causes, among other things, an increased secretion of saliva and sweat, constriction of the pupils and a drop in blood pressure, and summer leaf greening (Chlorophyllum molybdites) which causes severe disturbances in the digestive system – they caused the most common poisonings in Israel.
While most poisonings occur in the winter, since this is the season when most mushrooms emerge above the ground – the summer leafy green actually grows in the summer (as its name suggests), in grasses, and is therefore responsible for most cases of poisoning in the warm months. And if you are also used to the fact that the “correct” setting for picking mushrooms that turn out to be deadly is a forest, you might be surprised to learn that lawns – public and domestic – were the habitat that led to the greatest number of poisonings.
A fantastic mushroom
So how do you continue to collect but also protect yourself from poisoning? “Differentiating poisonous mushrooms from edible mushrooms cannot rely on smell, taste or cooking that will neutralize the toxins – because they contain substances that are resistant to heat,” explains Levinson. Therefore, she recommends not to collect without a qualified guide or without prior and in-depth knowledge. “Publishing the poisoning cases and raising awareness among the public about the dangers of collecting could help reduce the poisoning cases. In addition, it is important to keep children away from mushrooms that grow in lawns.”
However, and although their incorrect use may cause illness and even death – mushrooms are essential for all of us: they are responsible for the breakdown and recycling of natural substances, contribute to the growth of trees and plants and are used to produce various medicines, such as penicillin.

Due to all these – it would be appropriate if we protected them better from human harm. “Climatic changes such as dry years and accelerated urbanization processes that cause the reduction of natural areas – harm their distribution,” explains Levinson.
In addition, Israel is a semi-desert country, so the amount of mushrooms here is small compared to other regions. Therefore, the importance of nature reserves to protect the distribution of mushrooms is crucial. “Without nature reserves in Israel, where picking and gathering is prohibited – their situation would probably be worse,” says Levinson. “That’s why we need to guide the public to nature conservation and more modest gathering – so that the mushrooms will continue to grow here in the years to come.”
