oysters

20. Oysters
Oysters that haven’t been properly stored at a proper temperature can contain a very toxic bacteria called vibrio vilnifucus. This bacteria is easily killed by keeping the oysters at a very low temperature (below 40 degrees Fahrenheit) or when cooked at high temperatures (above 140 degrees Fahrenheit). But if you eat an oyster that contains this bacteria, you could become violently ill, with severe digestive distress common and sometimes including liver damage.
