Attached is an article about an oyster−related illness linked to ocean warmng. An outbreak of illness among cruise ship passengers in Alaska in 2004 led to the detection of disease−causing oysters about 620 miles farther north than they had ever been found before, possibly as a result of warming ocean waters.
I raise this because I always thought that oysters harvested that far north could not possibly carry the risk of disease that oysters harvested from the southern regions, including the Chesapeake Bay or the Gulf, have. It doesn't look like you can count on anything raw to be safe coming from the sea any more. Lord only knows what the pump-out of water from NOLA will do to the ecosystem and fishing industry down there over the next few years.
