Bacteria can multiply rapidly at room temperature, potentially leading to food poisoning. It is recommended to discard any cooked food that has been left out at room temperature for more than 2 hours to avoid the risk of illness. To prevent foodborne illness, always store perishable foods in the refrigerator promptly after cooking and consume them within a safe timeframe.
