I had a container of cooked chicken pie filling in my freezer and after our son moved back in, he brought his pet snakes and stored their food (dead chickens and rats) in the bottom shelf of our freezer. The trouble is, they had started to defrost in the car while he was moving his belongings. I wasn't happy about them going in the freezer but I relented because of how much it would've cost him to replace it all. It wouldn't have been so bad except I later found the lid had lifted on the tupperware container the pie filling was in. I resealed it and put the container in a plastic bag as well, but I'm not game to eat it now. It could have been open for a few days or more. Would the pie filling be edible or would it be contaminated by the rotten dead animal smell in the bottom of the freezer and should I throw it out?
