Background: On May 31, 2024, Chaiyaphum Provincial Public Health Office (PPHO) received the notification of 5 suspected cases of Mushroom poisoning from Nong Bua Daeng Hospital. All of them sought for medical care at Nong Bua Daeng Hospital on May 29, 2024. Therefore, the operation team of Chaiyaphum PPHO investigated this event on June 2, 2024 in order to confirm the outbreak as well as the diagnosis, to determine the distribution and the risk factors of the outbreak, and to recommend the prevention and control measures.
Methods: A descriptive epidemiology study was performed to interview all patients, the medical team at Nong Bua Daeng Hospital, reviewed medical records and performed active case finding during 1 May–6 June 2024 in 5 6 7 and 19 village, Nong Bua Daeng subdistrict, Nong Bua Daeng district. We also conducted the laboratory study and the environmental study.
Results: The outbreak of mushroom poisoning occurred in Nong Bua Daeng Subdistrict, Nong Bua Daeng District, Chaiyaphum Province. Five confirmed cases of mushroom poisoning were identified. Two cases were male, while the remaining three were female. The median of age was 53 years (Min-Max=46-61 years). The Median of incubation period was 1 hour 52 minutes (Min-Max=1-3 hours). All cases experienced mild symptoms, including nausea, vomiting, dizziness, and headaches. The outbreak was caused by the consumption of scleroderma mushrooms. Lack of knowledge and experience in mushroom picking were identified as the main risk factors. Active case finding both in patients’ households and the community did not identify any additional cases.
Recommendations: Strengthen the network of village health volunteers to continuously monitor Mushroom poisoning cases in communities, especially during the rainy season each year, activate charcoal stockpiling in subdistrict health promotion hospitals, providing health education about mushrooms to community members. Additionally, further study the risk behaviors and confidence levels of people collecting mushrooms on Phu Khieo to gather data for preventing recurrence in this area and expanding preventive measures to other high-risk areas in Chaiyaphum Province.
