The cause of the tourists' illness over the weekend remains under investigation, Fijian Tourism Minister Viliame R. Gavoka said.

Seven tourists who were hospitalized in Fiji last weekend after drinking cocktails at a luxury hotel were not poisoned by tainted alcohol, officials there say. Fiji’s Tourism Minister Viliame R. Gavoka told reporters Wednesday that the results of a toxicology report showed “no evidence of alcohol poisoning.

The tourists suffered from nausea, vomiting, and "neurological symptoms" after drinking a cocktail at a resort, per Fiji's health ministry.
