Fresh oyster shelf life.

Part of our gang here home was at the gulf last week & brought home 2 bushels of them in the shell. He got home last Saturday & we had plans for a Sunday shucking. Things came up, then the holidays, & now the feed is scheduled for tomorrow.

Not this guys first time with these, & I know he keeps them iced down well. He, I, & a few others know to throw away any that have opened. But I'm still a bit guarded over the meal. Food poisoning ain't fun, been there.

Any advice or suggestions on the situation?
