A Case of Group Mushroom Poisoning due to 'Chlorophyllum molybdites' / 日本農村医学会雑誌

ABSTRACT

We experienced a case of group mushroom poisoning. The victims were Chinese workers. They developed symptoms such as vomiting, diarrhea, and abdominal pain one hour after ingestion of wild mushrooms growing at a riverside. Generally, it is very difficult to identify quickly a species of wild mushroom. Therefore we were in trouble about the treatment because they might have taken deadly mushrooms, such as ‘Amanita versa’ and ‘Amanita virosa’. ‘Chlorophyllum molybdites’ looks like these mushrooms. In this case, the incubation period is different between Chlorophyllum molybdites and Amanita species, so we could know that the mushroom they had taken was not so dangerous. There are various folk believes about mushroom poisoning, but many of them are groundless. In this case, the Chinese workers also belived a wrong one. The problem is that a simple and easy method for distinguishing harmless mushrooms from poisonous one is yet to be established in society.
