After treatment， all patients were cured. The mushroom sample was identified as Amanita exitialis. The content of α-amanitin toxin detected in the remaining suspicious samples collected mushroom soup， boiled fruiting bodies， uncooked mushroom residual tissues， and no blood and urine samples were detected α- amanitin.ConclusionThis poisoning incident is caused by Amanita exitialis. The local villagers have weak awareness of food safety. It is necessary to strengthen the popularization of wild mushroom knowledge， establish a rapid detection technology system for mushroom poisoning， and reduce the occurrence of mushroom poisoning and death incidents.
