In Lampang, five Myanmar construction workers collected poisonous mushrooms to cook and share. They then suffered dizziness, fainting, diarrhea, cramps, bloating, and chest tightness. One person has died, and four others have been admitted to hospital. The mushrooms are suspected to be White Rangak mushrooms.
The incident involved five Myanmar workers hired for construction in Ban Bo Silam, Village No. 6, Pong Tao Subdistrict, Ngao District, Lampang Province. On the evening of 30 May, they gathered wild mushrooms and cooked them together. By the morning of 31 May, they began showing symptoms of mushroom poisoning, including dizziness, fainting, diarrhea, cramps, bloating, and chest tightness. They were taken to Ngao Hospital, but their condition did not improve by 3 June, so they were transferred to Lampang Hospital.
The latest update on the afternoon of 5 June 2026: the village headman of Ban Bo Silam and colleagues visited the patients at Lampang Hospital and learned that one of the five, Mr. Mong Phiu, aged 28, had died. The other four, including Mrs. Suayla, 30, the wife of the deceased, remain weak and experience difficulty breathing; doctors are using oxygen support.
Mrs. Jing, 46, suffered hepatitis but has been gradually improving after treatment. Meanwhile, Mr. Tor, 32, and Mr. Jai Jeng Pu, 50, have mostly recovered, only experiencing mild fatigue.
According to those who gathered mushrooms with the deceased Mr. Mong Phiu and Mr. Tor (a craftsman), Mr. Tor confirmed the mushrooms resembled those he regularly collected and ate in Chiang Mai. They found them behind the village and each picked two bags. Mrs. Jing cooked the mushrooms, which she said were similar to ones she had often eaten, known in Shan language as “Peacock mushrooms.” Based on photos shown, these are believed to be White Rangak mushrooms. The cooking involved only ordinary seasonings plus tomatoes and garlic, with no other additives. After cooking, the stew was divided into two bowls: one bowl was shared between Mr. Mong Phiu and his wife, and the other was shared by three people.
Mr. Mong Phiu and his wife began experiencing abdominal pain, vomiting, and diarrhea from 2 a.m. on 31 May. The other three developed symptoms around 6 a.m. Friends took all of them to Ngao Hospital for treatment until 3 June, when they were transferred to Lampang Hospital. As of now, Mr. Mong Phiu has died, and the other four remain hospitalized at Lampang Hospital.
