Officials in a southwestern Spanish town say a mother, father and one daughter belonging to the same family have died from food poisoning, and have ordered an investigation into the deaths.

Local government spokeswoman Miriam Burgos told state broadcaster RTVE that a 13-year-old girl was the only family member to survive, having emerged Sunday from the intensive care unit of a Seville hospital after suffering from food poisoning.  Reporting from Alcala de Guadaira, 17 kilometers (10.5 miles) east of Seville, RTVE said in its afternoon news bulletin that neighbors of the family had said both parents were unemployed and were known to have accepted free food from local stores.
