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.
