The father of an Australian teenager who died from suspected methanol poisoning while on a backpacking holiday has issued a plea to the Laos government to fully investigate his daughter’s death and ensure such incidents don’t happen again.

Six travelers have died from suspected methanol poisoning in Vang Vieng, Laos. Most of these incidents occur in Asia, according to Doctors Without Borders.

The problem with methanol poisoning is that it looks very much like alcohol poisoning. And delays in treatment can be fatal.

The Lao government is "profoundly saddened" by the deaths of foreign tourists from drinking alcohol contaminated with methanol and pledged to prosecute those responsible. Two Danes, two Australians, a Briton and an American have died after visiting Vang Vieng,
