just a note of general agreement. fried, baked, grilled, steamed, microwaved oysters are all good.

raw ones are good too, but on some occasions can leave hep A markers in one's blood workup.

not that it hurts the liver all that much, but once the markers are there, they're there.

it also can come from dirty/affected well water, and various other sources.

dirty seafood from affected areas is a high probability likelihood.
