Government expands travel warnings after surge in deadly fake alcohol poisonings

The United Kingdom's Foreign, Commonwealth and Development Office (FCDO) has warned that tourists visiting Ecuador, Japan, Kenya, Mexico, Nigeria, Peru, Russia and Uganda may face a risk of methanol poisoning from counterfeit or contaminated alcohol.

"The expanded list builds on existing guidance for countries including Thailand, Laos and Vietnam," the agency noted.

Methanol, an industrial chemical typically found in antifreeze and windshield washer fluid, is deadly to humans, according to health agencies.

The chemical is sometimes added to alcoholic drinks to cut costs. And because it's flavorless, odorless and colorless, poisoning is difficult to detect until symptoms appear.

Hamish Falconer, the British minister responsible for consular and crisis matters, said in a statement that "by the time travelers realize the danger, it can be too late.

"Methanol binds to the same receptors as alcohol and will give you the same elated feeling," the New Jersey-based physician said. 

"However, it is toxic to the body and will lead to death if consumed in modest quantities without treatment."

"It has a very high mortality rate and will require hospitalization and [intensive care] monitoring if consumed in high volume," he said.

"When traveling abroad, trust your instincts and know the source," the security strategist said.

"Most methanol poisonings happen when tourists buy or accept alcohol from unverified sellers or bars using counterfeit spirits."

By sticking to sealed bottles and reputable venues, tourists can stay safe from poisoning, Coursen advised.

"Cheap cocktails and unmarked bottles are a red flag," he said. "If a drink tastes harsh or chemical, don't finish it.
