Man Arrested for DUI at Four Times Legal Limit Despite Not Drinking

Auto-brewery syndrome, also known as ABS, is a rare condition that can cause a person’s body to produce alcohol internally, leading to impaired driving abilities without actually consuming alcohol. This unique case was recently highlighted in The New York Times, shedding light on a condition that may be more common than previously thought.

The story featured a brewery worker in Belgium who was stopped by authorities for suspected drunk driving. Despite having a blood alcohol level four times the legal limit, it was later discovered that he was not under the influence of alcohol from drinking, but rather due to his body’s natural fermentation process.

ABS occurs when fungi in the gastrointestinal tract convert ingested carbohydrates into ethanol, mimicking the effects of alcohol consumption. This can lead to symptoms of intoxication such as impaired coordination and memory loss, even without actual alcohol consumption.

The man in question faced multiple DUI charges before being diagnosed with ABS by medical professionals. Following a strict diet and receiving medical treatment, he was acquitted of the charges. This case highlights the importance of recognizing and addressing uncommon medical conditions that can impact driving behavior.

While ABS is rare, recent research suggests that it may be underdiagnosed in others. The potentially dangerous implications of this condition were seen in a case where a woman in New York registered a blood alcohol level of 0.40 during a routine traffic stop, a level that can be fatal. With only a few dozen diagnosed cases worldwide, more awareness and understanding of ABS are necessary in the automotive industry to ensure road safety.
