How long can home fries stay out in room temperature and still be safe to eat when sealed in a plastic take out container?

Home fries are tastiest and safest when eaten right away.

Everything Dr. Potato has learned points to this…bacteria grow rapidly at temperatures between 40°F - 140°F. In general, cooked fries should be discarded after two hours if left at room temperature. A sealed container with fries will certainly accelerate the temperature and humidity that fuels bacteria growth, so figure even less time for safe consumption.
