Okay... so my question is in regards to say a plate of cooked food. How long does it stay good for at room temperature. I understand IDEALLY it should be put in the fridge to save for later. But there are those certain circumstances where that is not possible. So say I go out to lunch (12 noon) and I have leftovers I save until after work are they still good 5 or 6 hours later when they have been left at room temperature? I don't want to poison myself KWIM LOL. So what should I do? How long does food last like that? What is the longest amount of time cooked food can safely be left at room temperature?Like 'pizza', 'ribs', 'chicken', 'hamburgers' etc...

Each food has a different time limit. It also depends on how it's cooked. For proper safety, it should never be left out more than an hour.
