A semi rolled-over and spilled about 11,000 salmon onto the highway. As the fish flopped around on the road, the truck driver was charged with DUI. But it turned-out he had ‘auto-brewery syndrome’, a condition in which his body makes its own alcohol. This condition is rare but has been identified many times. For a person charged with DUI (called ‘OVI’ in Ohio) who drank no alcohol, auto-brewery syndrome may be responsible.
