Millions of Americans traveling abroad each summer for vacation may be unknowingly exposed to the lethal danger of methanol-laced alcohol. This toxic substance, often illegally added to spirits to increase alcohol content or as a cheaper substitute for ethanol, poses a significant health risk in popular tourist destinations.
Rachel Villarreal and her boyfriend Anthony Grigsby experienced this firsthand during a trip to Mexico City in January 2024. After accepting a free shot of pulque, a traditional Mexican alcohol made from agave, during a boat ride on the Xochimilco canals, Villarreal became severely ill. Within an hour, she experienced cramping and stomach pain, which worsened to include vomiting and body aches. Her condition deteriorated to the point where she lost consciousness and had to be rushed to the hospital. Doctors discovered traces of methanol in her blood, a substance known to cause brain swelling, organ shutdown, and breathing difficulties.
Villarreal was placed in an induced coma and intubated. She has since died and been resuscitated three times, undergone numerous surgeries including a tracheostomy, and required extensive rehabilitation to relearn how to walk and speak. The poisoning has forced her and Grigsby to leave their jobs and has led to ongoing battles with insurance companies.
Methanol is a colorless, tasteless, and toxic alcohol commonly used in industrial products like antifreeze. Its intentional addition to beverages, particularly in regions with less regulated alcohol production, is a growing concern. While sometimes a byproduct of improper distillation in homemade spirits, it is increasingly being used as a cost-cutting measure. According to Médecins Sans Frontieres (MSF), as little as two teaspoons of methanol can cause blindness, and a mouthful can be fatal. The fatality rate for untreated methanol poisoning is between 20-40%.
This issue is not confined to Mexico. Reports of methanol poisoning have surfaced in 80 countries, with 71% of documented cases occurring in Asia, a continent visited by millions of Americans annually. In 2024, a couple from the UK and South Africa died from methanol poisoning in Vietnam. In 2009, 25 people, including American tourist Rose Johnson, died in Bali after consuming methanol-contaminated rice wine. Indonesia has reported the highest number of methanol incidents globally in the past two decades.
Southeast Asia has also seen fatalities, with six foreign tourists, including American James Louis Huston, dying in Laos in 2024. In Costa Rica, 26 people died in the summer of 2019 after consuming alcohol tainted with methanol. IMAGE8
Mexico faces a significant problem with a counterfeit alcohol market, partly fueled by high taxes on spirits. Authorities recently seized a batch of tequila containing lethal levels of methanol, linked to five deaths and 28 hospitalizations. The UK's Foreign, Commonwealth and Development Office has issued a travel warning for Mexico due to the high risk of methanol poisoning. Since 2010, Mexico's health authority has seized over 1.4 million gallons of counterfeit alcohol. In 2017, a family from Wisconsin alleged that their 19-year-old daughter, Abbey Conner, died from a methanol-laced drink at a Cancun resort, leading to a wrongful death lawsuit against the establishment.

Ashley King, an actor and writer from Calgary, became legally blind at age 18 after a backpacking trip in Bali where she consumed a cocktail contaminated with methanol.

King suggests that tourists stick to sealed beverages like bottled or canned beer and wine, which are less likely to have been tampered with. "I think it's super important that people know that methanol poisoning exists and that it happens," King told the Daily Mail. IMAGE2
While international regulations are difficult to enforce, awareness and informed choices can help mitigate the risks. For Villarreal and Grigsby, the experience has profoundly altered their lives, making future travel to Mexico a distant prospect. Grigsby stated that if they were ever to return, they would abstain from drinking alcohol altogether.
