I am not claiming this as a precedent or foundation rule for any other similar situations or for any one who may be reading this about their own stupidly left out pack of meat, but we tested it and have been fine. I will however cuation about 'on our cold kitchen floor for less than four hours near air conditioning' and 'left in a car trunk in august'. This was one very specific case.
Those of you who think this is dangerous will say we got lucky, those who felt the evidence suggested a very low likelihood of having a problem were right but could have been wrong. I think a cautious intelligent examination made us confident it was wortth a shot and now a large amount of sliced meat doesn't need to go to waste.
Thank you all regardlesss of your opinion.
