Australia has warned travelers against drinking spirits made by a Laos distiller, following the deaths of six foreign tourists from suspected methanol poisoning in the Southeast Asian country.

Authorities in Laos have reportedly banned the sale and consumption of a vodka and whisky brand after six tourists died from suspected methanol poisoning in Vang Vieng earlier this month. An Australia travel advisory published on Friday said the Southeast Asian country has banned Tiger Vodka and Tiger Whisky.

The U.S., Australia and U.K. have issued warnings for travelers in Vang Vieng after several tourists died in a suspected methanol poisoning outbreak.

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

The US State Department issued a warning to travelers to be “alert to the potential risk of methanol poisoning.” But what is methanol, and how do you avoid it?

Six tourists from Australia, Denmark, the United States, and the United Kingdom died in Laos due to methanol poisoning. In response to these tragic events, the country's authorities banned the sale and consumption of a specific brand of vodka and whiskey.
