Investigation and analysis of Galerina sulciceps poisoning in a canteen

Guizhou Province in China has an abundant resource of wild mushrooms, including numerous poisonous species which contain various toxins. The mortality rate from wild mushroom poisoning has been high in this area in recent years. Galerina sulciceps is a dangerously toxic mushroom which can be fatal if ingested.

we report on an epidemiological investigation of G. sulciceps poisoning which occurred in Duyun City of Guizhou Province. The characteristics of this species, its toxicity, observed clinical features, laboratory data, treatment modality, and prognosis were investigated in order to provide a reference point for the prevention and treatment of this kind of mushroom poisoning.

Thirteen employees showed toxic symptoms after ingesting wild mushrooms the previous day in a company canteen. Clinical manifestation varied from gastroenteritis to hepatic and renal dysfunction. Most of the 13 patients presented with nausea, vomiting, abdominal pain, diarrhea, and elevated levels of biochemical indices of hepatic and renal function, during which transaminase concentration peaked within 48-72 h. At 48 hours post-ingestion, all patients had hemodialysis, in addition to supportive care for hepatic and renal injury with oral Silibinin and Shenshuaining. All acute renal injury had resolved by day 10, and liver transaminases had trended toward normal in all patients and they were discharged. At follow-up in 30 days, both liver and renal function had completely recovered in all.

This poisoning occurs as a result of unintentional consumption of G. sulciceps, which is relatively rare in mushroom poisonings. All patients recovered fully after timely diagnosis and treatment. To prevent wild mushroom poisoning, the best preventive measure is to educate the public not to gather and eat any unidentified wild mushrooms.
