I know I'm going to get in trouble but I just had to put in my two cents. I smoked a turkey before Christmas. It was heavily smoked and we served about half on Christmas eve. I put the rest in two bags and froze one and ate on the other till new years eve and I ground it up and made a cheese ball with it. We had twenty people tasting and loving the cheese ball and not one got sick. By the way the left over cheese ball is on my desk right now and I am eating it on celery sticks.
I think people have gotten extremely wasteful. My grandmother cooked pork chops for dinner and left the remaining chops out on the table till breakfast and she never once got sick. I keep everything in the fridge at least a week before tossing it to the dogs. They never get sick on left overs either and love our leftovers. I believe your eyes and nose can tell you when it is time to toss things out.
