stick it on extra hot and microwave off all those germs
a lot of these food products are heated and reheated and reheated so if it's your turn for poisoning, then so be it (it comes with the territory), but 8 hours won't do it really if you got it from a place that seemed to have "okay" standards.
i leave stuff out all the time (up to 2 days) but there's typically got to be something wrong with the food for it to harm you.
