The latest fatality was a 19-year-old woman from Australia, confirms the country's Foreign Minister Penny Wong. The 19-year-old's same-aged friend has also died.
Thus, six people have died after the suspected methanol poisoning, which is believed to have occurred when guests drank alcoholic beverages at a hostel in the tourist town of Vang Vieng in Laos.
Among the deceased are also citizens from Denmark, the United Kingdom, and the USA.
Several countries have urged citizens in the country to be cautious about what they drink.
"Be careful when drinking alcohol, especially cocktails and drinks containing spirits that may have been adulterated with harmful substances," wrote the Swedish embassy on Thursday.
It is impossible to see, taste, or feel any difference between regular drinkable spirits in the form of ethanol and the dangerous methanol. But not everyone understands the risks, so in parts of Asia, for example, it is not entirely uncommon for tragedies to occur in connection with the use of cheap methanol in drinks.
