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.
