Mushroom Poisoning Outbreaks - China, 2021.

Mushroom poisoning is one of the most serious food safety issues in China. Most poisoning incidents resulted from eating mushrooms causing gastroenteritis and psycho-neurological disorder from which patients usually could fully recover. Most deaths resulted from species causing acute liver failure and rhabdomyolysis, and the remaining deaths were attributed to acute renal failure and hemolysis. In 2021, the total number of investigations was 327 from 25 provincial-level administrative divisions, involving 923 patients and 20 deaths, and the overall mortality was 2.17%. Overall, 74 poisonous mushrooms causing 6 different clinical syndromes were successfully identified, 15 of which were newly recorded in China as poisonous mushrooms. Considering the potential huge risks for collecting and eating wild mushrooms, we strongly advise not collecting and eating unfamiliar wild mushrooms. Promoting knowledge about poisonous mushrooms is essential and urgent to reduce mushroom poisonings. Precise species identification timely after mushroom poisoning is important for appropriate diagnosis and treatment. Many deaths were ascribed to delayed hospitalization.
