The infection reportedly turned the sugars and starches he ate into ethanol, getting him drunk, Stuff.co.nz reported.
After the 61-year-old man showed up at a hospital reporting dizziness, it was found that his blood alcohol level was 0.37, which is enough to kill a person.
According to the report from the International Journal of Clinical Medicine, the man was suffering from condition known as gut fermentation syndrome, or Auto-Brewery Syndrome, and was likely infected with the yeast from something he ate or drank.
