Methanol poisoning has been thrust into the spotlight following recent tragic incidents, including the deaths of two Melbourne teens in Laos. Methanol, a highly toxic form of alcohol, is often mistaken for ethanol—the type of alcohol found in beverages—due to its similar appearance and smell. Here’s what you need to know to stay safe.

What Is Methanol?

Methanol is a colorless, flammable liquid used in industrial products like windshield cleaning, antifreeze, and fuel. Unlike ethanol, the alcohol in beer, wine, and spirits, methanol is highly toxic and cannot be safely consumed.

When the body processes methanol, it produces formaldehyde and formic acid, both of which are toxic and can lead to severe symptoms, including:

• Abdominal pain
• Chest pain
• Blurred vision or blindness
• Seizures
• In severe cases, death

Can You Test for Methanol in Drinks?

Currently, there are no home tests or portable devices widely available to detect methanol in drinks. However, laboratory techniques can identify methanol with precision.

Methods Used in Labs

1. Gas Chromatography–Mass Spectrometry (GC-MS):
   • Separates chemicals based on size and volatility.
   • Used to distinguish ethanol from methanol.
   • Expensive and not portable.
2. Sodium Dichromate Test:
   • Mixes the liquid with sodium dichromate and sulfuric acid.
   • Methanol produces a pungent, irritating smell, while ethanol gives off a fruity aroma.
3. Magnetic Resonance Spectroscopy:
   • Places the liquid in a strong magnetic field to identify chemical characteristics.
   • Commonly used for analyzing home-brewed alcohol.

Emerging Technology

Researchers in Switzerland are developing a portable smartphone-based methanol detector, similar to a breathalyzer, which can detect methanol vapors. While promising, this technology is not yet commercially available.

What to Do Without a Test

In regions with less stringent quality controls, methanol contamination can occur unexpectedly. If you don’t have access to testing methods, follow these precautions:

1. Choose Trusted Sources

• Drink only at reputable bars or establishments.
• Avoid homemade or unregulated alcohol.

2. Stick to Sealed Containers

• Only consume beverages from sealed bottles or cans that you open yourself.

3. Be Aware of Symptoms

• Early symptoms of methanol poisoning include:
  • Nausea and vomiting
  • Abdominal pain
  • Vision disturbances (blurred vision, seeing spots)
  • Drowsiness
• Severe cases can lead to blindness, seizures, or death.

4. Seek Medical Attention Immediately

If you suspect methanol poisoning, go to the hospital immediately. Early treatment can significantly improve outcomes.

Why Methanol Poisoning is Dangerous

Methanol poisoning can have devastating effects on the body, particularly due to the toxic breakdown products it creates. According to experts:

• Symptoms can develop within hours to days of exposure.
• Treatment often involves administering ethanol or fomepizole, which block methanol’s toxic metabolism.

Final Thoughts

Methanol is undetectable without proper testing, making it crucial to take preventive measures. By drinking from trusted sources and being vigilant about symptoms, you can reduce the risk of methanol poisoning. Organizations like Doctors Without Borders and Red Frogs offer resources and advice for travelers.

Remember, if in doubt, seek medical help immediately—the earlier, the better. Methanol poisoning is a serious public safety issue that requires awareness and caution.
