Seven foreigners in Fiji were hospitalized on suspicion of poisoning after drinking pina coladas in the bar of a five-star resort, local authorities said.

Five are tourists, one from the US and the rest from Australia, aged between 18 and 56. Two others are foreigners living in Fiji, according to local media reports citing the Ministry of Health.

Initial investigations are ongoing and no further cases have been reported, authorities said.

Sydney resident David Sandoe told the Australian Broadcasting Corporation (ABC) that his daughter Tanya and granddaughter Georgia were among those affected. But he added that they returned home and were doing “very well” considering what happened.

“It’s very difficult to take a call at 11 o’clock at night … and your daughter says they’ve been poisoned and are in the hospital,” Mr. Sandoe said, adding that Georgia had suffered a seizure.

The ABC previously reported that a 56-year-old Australian woman was being medically monitored in hospital and a 19-year-old Australian woman had suffered “serious medical episodes”.
