Can I cook it tomorrow (four days later) without poisoning anyone? Tue Jul 19 20:12:28 -0700 2005 0 Far Fegnuyan 1 1477155 Yes, it will bve fine. Cook it up. I just grilled sausages I bought on Sunday. They are fine and they would be more likely to go off than your steak. Tue Jul 19 20:16:47 -0700 2005 1477154 0 Candy 2 1477170 No, you won't kill anyone. And if the marinade is in anyway acidic, you will have denatured every protein molecule in that meat and it will have the mouth feel of Gerber's peas. Wed Jul 20 00:35:50 -0700 2005 1477155 0 dk
