Don't eat raw or undercooked oysters or other shellfish. Fully cook them before eating, and only order fully cooked oysters at restaurants. Hot sauce and lemon juice don't kill Vibrio bacteria and neither does alcohol. Some oysters are treated for safety after they are harvested.
How to Serve. You can top the hot oysters with a bit of butter, compound butter, your favorite barbecue sauce, or, for something tasty and a bit different, a dollop of pesto. You can also remove the top shell from the cooked oysters, add a bit of sauce to each, and return to the grill for a deeper flavor.

Vibrio is destroyed by cooking shellfish to an internal temperature of 145° F for 15 seconds. Eat only well-cooked shellfish, especially in summer months.
If you are at high risk, do not eat shellfish iced or "on the half shell." Only thorough cooking — boiling, heavy steaming, frying, broiling or baking — will kill Vibrio vulnificus.
No vaccine is available for norovirus. To prevent norovirus infection: While cooking shellfish can reduce the risk of norovirus illness, quick steaming or cooking until the shells just open may not be enough to protect against norovirus illness. Norovirus can survive cooking temperatures up to 140°F.
Signs and symptoms of Vibrio vulnificus infection can include: Watery diarrhea, often accompanied by stomach cramping, nausea, vomiting, and fever. For bloodstream infection: fever, chills, dangerously low blood pressure, and blistering skin lesions.
