Singapore - A second Singapore woman has gone into a coma after suffering acute food poisoning a day after the first victim's death, media reports said Tuesday.

Noraini Kasim, 59, is in a coma at a local hospital after having eaten from a local food stall last week.

Comatose Aminah Samijo, 57, died Monday in hospital, and Rosiah Samat, 38, lost her 2-month-old foetus in a miscarriage caused by a serious bout of diarrhea and bleeding brought on after eating the same food.

News reports said more than 110 people have been treated at Singapore's six main hospitals for food poisoning after eating at the stall, but it was not known how many more had sought treatment at private clinics and medical centres.

The Straits Times quoted doctors as saying that deaths from food poisoning were rare.

Police have classified Aminah's case as one of unnatural death and are investigating. The highly popular food stall is also under investigation. (dpa)
