raw oysters

The consumption of raw oysters is being discouraged in the New York area, thanks to the appearance of Vibrio vulnificus, aka, the flesh-eating bacteria. Although Vibriosis is (thankfully) very rare, it can also be very serious, even deadly. The exceptionally warm ocean temperatures this summer have allowed the bacteria to spread northward, where there has been one confirmed death from raw oysters and two others from skin infections. Is there anything to worry about here?
