Abstract
What is already known about this topic? Among all food poisoning, poisonings caused by wild mushrooms containing amanitin toxins have the highest case fatality rate. Amanitin toxins can cause acute liver function damage, and symptoms of the poisoning can include vomiting and diarrhea in early stages and progressive liver damage 2–3 days later. What is added by this report? Before 2019, there were about 1–2 cases of wild mushroom containing amanitin toxins poisoning each year in Zhejiang Province. In 2019, 10 cases were identified through disease investigation and toxin detection and biological identification in Shaoxing City, Zhejiang Province. All patients had a history of wild mushroom consumption. What are the implications for public health practice? In the summer, some people collect the wild mushrooms for consumption. In China, about 20 species of mushrooms can cause death, and most people lack the ability to identify which mushrooms are edible. To combat this, effective science popularization and prevention and control work will be able to reduce the occurrence of related poisoning events.
Highlights
From June 28 to July 15, 2019, 3 suspected poisoning events continuously occurred in Shaoxing City, Zhejiang Province, China
The Xinchang County CDC of Shaoxing City, Zhejiang Province, received an event report from a local hospital that 6 patients in a family went to a doctor with suspected food poisoning on June 29, 2019

Summary
From June 28 to July 15, 2019, 3 suspected poisoning events continuously occurred in Shaoxing City, Zhejiang Province, China. A total of 10 patients with different degrees of liver damage were found, and 1 patient died so the case fatality rate was 10%. The agencies for disease control and prevention formed a team to investigate this incident. Using a combination of epidemiological investigations, laboratory toxin analysis, and biological identification results of poisonous samples, the poisoning events were determined to be caused by the ingestion of a wild mushroom (Amanita rimosa) containing amanitin toxins. Through popular science publicity and education on wild mushroom poisonings and the prohibition of wild mushroom collection/consumption, similar poisoning events were reduced until the middle of August
