Toxicology tests on the ingredients of drinks consumed by seven tourists who fell ill in Fiji showed “no methanol or illicit substances,” authorities on the South Pacific island said Wednesday.

A toxicology report into the suspected alcohol poisonings at Fiji's Warwick Resort that left four Australians critically ill has found no traces of methanol.

Health Ministry permanent secretary, Dr. Jemesa Tudravu says they cannot confirm at this stage whether methanol poisoning was involved in the incident at Warwick Fiji Resort over the weekend. Dr. Tudravu confirms that two of the seven guests were in serious condition and remain admitted at the Lautoka Hospital.

The Fijian government says testing has shown methanol poisoning was not the cause of an incident which saw four Australians and three others hospitalised.

Toxicology tests in Fiji have ruled out alcohol poisoning from a hotel bar's cocktails as the cause of a mystery illness that sent seven guests to hospital, the Pacific nation's government said on Wednesday.
