Cocktails from a Fiji resort where seven people fell ill from a suspected poisoning incident did not contain methanol or illicit substances, authorities say.
Fiji Deputy Prime Minister Viliame Gavoka says a toxicology report of the pina colada mixture served at the five-star Warwick Fiji resort found the drinks weren't laced with illegal alcohol.
"After testing the ingredients of the drinks served to guests by the Fiji police force, I can confirm that no illicit substances or methanol were found in the ingredients or liquor samples," he told reporters on Wednesday.
Fijian police and its health department continue to investigate the matter.
Mr Gavoka also said all seven affected people, which includes four Australians, had been discharged from hospital and were recovered.
The group, aged between 18 and 56, was taken to hospital on Saturday after drinking the cocktails at the resort on the south coast of Viti Levu island.
"The findings that there is no evidence of alcohol poisoning is great news for Fiji," Mr Gavoka said.
Australian mother and daughter, Tanya and Georgia Sandoe landed back in Sydney on Monday evening after being released from hospital.
Mr Gavoka said the South Pacific nation was a safe and reliable destination for travellers.
"Fiji holds the highest standards when it comes to food, beverages and overall safety (and) the health and wellbeing of our visitors remains our top priority," he said.
The incident follows the death of two Australians in Laos, where they were among several victims of a suspected mass ethanol poisoning.
About one million Australians visit Fiji each year and tourism contributes significantly to the nation's economy.
