According to the FDA, the safety window of warmed foods, especially meats, is roughly two hours. Beyond that the food reaches that perfect point for bacteria to go nuts.
With that said, I think a lot of us are guilty of letting food sit for way, way longer than we should, only to eat it later and be fine. Hell, I've left pizza out for a couple days straight during my college years. Assuming you have no conditions where as your immune system is naturally weak, I'd think you'd be fine.
