Abstract:
Objective:To describe a systematic approach on identification of poisonous mushroom by investigating two cases of Omphalotus guepiniformis poisoning in Jianyang district, Nanping, Fujian province. Methods:Two incidents of food poisoning on 10 migrant workers were investigated. The remaining suspected mushroom samples were collected and the same fresh mushroom specimens were also collected in the following field investigations from the same dead tree and fallen trunk. These mushroom specimens were identified based on morphological and phylogenetic analyses.Results:On November 24 and 26, 2018, 8 and 2 migrant workers from Jianyang District, Nanping ate wild mushrooms and developed acute nausea, vomiting, abdominal pain and other symptoms within 10 to 90 min after consumption. They were diagnosed as mushroom poisoning, with gastroenteritis as the main manifestation. Further analysis showed that the more poisonous mushroom were consumed, the shorter latency and longer duration of nausea and vomiting were resulted. After admission, gastric lavage, catharsis, acid preparation, gastric protection, fluid replenishment and other symptomatic support treatments were given in time, all patients were discharged in 1-3 d. Based on morphological and phylogenetic analyses, the samples were identified as O. guepiniformis. Conclusions:The two incidents were caused by accidental consumption of O. guepiniformis. Awareness education about poisonous mushroom should be provided to migrant workers to prevent more such poisoning incidents in the future.
