Abstract

Abstract Issue Mushrooms are considered as ingredient of gourmet cuisine across the globe and mushroom poisonings can occur because of misidentification of a poisonous species as edible. Of the vast number of mushroom species, approximately 100 are toxic(**). Description of the Problem Mushroom poisoning is a public health problem. People should be educated about this poison as often there are no guidelines about the treatment of mushroom toxicity. Despite treatment, the prognosis can be mortal. In the Department of Hygiene and Health Prevention (ATS Val Padana, Italy) expert mycologists offer their consultation free of charge to people who pick mushrooms and register, for each consultation, quantity and toxicity of collected mushrooms. Results In 2018-19, 279 consultations were offered: 124(44.44%) in 2018, 155 (55.56%) in 2019. 58.42% of mushrooms were considered not dangerous for human health, without any difference among the two considered years (p = 0.167). 233.7 kg mushrooms were considered edible (mean 2.71, SD 16.44), 92.95 kg were considered dangerous and destroyed (mean 1.39, SD 6.99). The most identified species were: Agrocybe aegerita (11.47%), Armillaria Mellea (29.75%), Boletus edulis (6.45%), Macrolepiota venenata** (1.43%, N = 4), Xerocomus badius (2.51%), Lyophillum loricatum (1.79%), Agaricus Xanthodermus** (3.23%, N = 9). Intoxications occurred among people who did not refer to our mycology unit. Conclusions Mushroom poisoning represents a major health risk and as it's often consequence of misidentification, a free of charge consultation offered by experts is fundamental to avoid intoxications or deaths. Key messages Mushroom poisoning presents a major health risk. A free of charge consultation offered by experts is fundamental to avoid intoxications or deaths.
