Raw oysters are delicious, but can carry the pathogen vibrio vulnificus, which can be deadly, especially if you've already got a weakened immune system. Here are 7 myths about raw oysters from the FDA, so you have all the facts before you dive into that next raw oyster platter. 
 
MYTH: Eating raw oysters are safe if you drown them in hot sauce, which kills everything. 
FACT: Nothing but prolonged exposure to heat at a high enough temperature will kill bacteria.
 
MYTH: Avoid oysters from polluted waters and you'll be fine.
FACT: Vibrio vulnificus in oysters has nothing to do with pollution. Rather these bacteria thrive naturally in warm coastal areas (such as the Gulf of Mexico) where oysters live.
 
MYTH: An experienced oyster lover can tell a good oyster from a bad one.
FACT: Vibrio vulnificus can't be seen, smelled, or even tasted. Don't rely on your senses to determine if an oyster is safe.
 
MYTH: Alcohol kills harmful bacteria.
FACT: Alcohol may impair your good judgment, but it doesn't destroy harmful bacteria.
 
MYTH: Just a few oysters can't hurt you.
FACT: The seriousness of any case depends on many factors, including how much bacteria is ingested and the person's underlying health conditions.
 
MYTH: Avoid raw oysters in months without the letter "R" and you'll be safe.
FACT: While presence of Vibrio vulnificus bacteria is higher in warmer months, according to the Department of Health and Human Service's Centers for Disease Control and Prevention (CDC), a full 40 percent of cases occur during colder months from September through April.
 
MYTH: Raw oysters are an aphrodisiac and will cure a hangover.
FACT: There is no scientific evidence that either of these commonly held beliefs is true.
