How can I prevent Vibrio vulnificus food poisoning?
The best way to prevent this type of food poisoning is to not eat raw oysters or other raw shellfish and to cook all shellfish (oysters, clams, mussels) thoroughly.
Boil shucked oysters for at least 3 minutes or fry them in oil for at least 10 minutes at 375°F (191°C). For shellfish in the shell, either:
- Boil until the shells open and continue boiling for 5 more minutes, or
- Steam until the shells open and then continue cooking for 9 more minutes.
Do not eat those shellfish that do not open during cooking.
You should also:
- Avoid cross-contamination of cooked seafood and other foods with raw seafood and juices from raw seafood. Don't prepare them in the same place. And don't use the same cutting board when preparing them.
- Eat shellfish immediately after cooking, and refrigerate leftovers.
- Avoid exposing open wounds or broken skin to warm saltwater or brackish water or to raw shellfish harvested from such waters.
- Wear protective clothing, such as gloves, when you handle raw shellfish.
