Two hours maximum. After that time, the meat should be re-heated or refrigerated. If the ambient temperature is very warm, reduce that to one hour.
No longer than 4 houres
i think it goes bad in like a whole 24 hours.
Provided it is in an airtight container (a plastic bag and/or a breadbin), up to a week.
you should never let it sit out on the counter. Take it out the day before and let sit in the fridge over night
