Just to get a different perspective on Vibro vulnificus, those who have had serious problems with it either have a damaged immune system (cancer treatment, certain leukemias, being my age or older, etc.), liver disease, or a few other mostly uncommon conditiions. Most young, healthy people can handle it without even knowing they were even exposed.

On the other hand, eating raw oysters, even if you are healthy, is begging for other trouble. I have had hepatitis A and really serious gastroenteritis at different times of my life from eating those delicious nuggets. After I learned a few things about what drifts down onto the oyster beds from the through-hull fittings on oyster boats, I eat only steamed, fried, etc. oysters and refuse to think about it.
