Question: how long does it take for food to go bad at room temperature?
Answer: The "2-hour rule" states that perishables left at room temperature for more than two hours should be discarded. If the food is being kept in an area that is 90 degrees Fahrenheit (32.2 degrees Celsius) or above, leftovers should be refrigerated to 40 degrees Fahrenheit (4.4 degrees Celsius) or below within one hour.
