Elkcrazy8: I have always been told you have to let the meat "breathe" for a while to cool down before you put it in an airtight bag. Do you hang it first and let it chill down some before you seal it? I was told that if you didn't, it would spoil, but maybe that is because it seals in the heat if just hung in the air. In your situation, the water is chilling down the meat and taking the heat away through the plastic, so maybe the "breathing" period is unnecessary?
