FOUR mushroom farmers were recovering in hospital in Pursat province after drinking poisoned rice wine on Monday, police officials said yesterday. Chhon Chhorn, director of medical examination for the provincial police, said officials were investigating the source of the tainted wine. “According to another worker, before the four victims were transferred to hospital, they were dizzy, wanted to vomit, and had blurry vision after drinking the wine for 10 minutes,” he said. Last month, a wine seller was arrested in Pursat province after wine that he had sold caused the deaths of six people and injured 15 others.
