(Pixabay pic) PETALING JAYA: A mother and her nine-year-old son are believed to have died from food poisoning in Tawau, Sabah, after attending a wedding kenduri on Saturday. Masran Amin, 43, said his wife, Nazuah Pili, 36, and eldest child, Amran, experienced severe vomiting and diarrhoea several hours after returning from the kenduri which was held in the morning, Berita Harian reported. He had returned home from work to find them lying on a mattress in the living room, with both appearing weak. "I did not suspect anything at first, but my wife was frequently going to the toilet and vomiting before lying back down," he was quoted as saying. He said Amran barely moved as he laid on the mattress. Masran said his two other children also experienced suspected food poisoning but were treated at a nearby clinic. He said he also experienced food poisoning after consuming some of the food his wife had brought home from the kenduri. Nazuah and Amran were laid to rest last night after an autopsy was done. Tawau deputy police chief Champin Piuh confirmed that an investigation was underway.
