Cooked hot dogs should not be left out at room temperature for more than 2 hours. Bacteria can multiply rapidly in the "danger zone" temperature range between 40°F (4°C) and 140°F (60°C), increasing the risk of foodborne illnesses. Therefore, it's important to properly store cooked hot dogs to ensure food safety.
If you need to keep cooked hot dogs for longer than 2 hours, it's advisable to refrigerate them promptly. Place the hot dogs in shallow, airtight containers or wrap them tightly in foil or plastic wrap before storing them in the refrigerator. When stored correctly, cooked hot dogs can be safely consumed within 3 to 4 days.
Remember to always use your best judgment and prioritize food safety. If the hot dogs have been left out at room temperature for an extended period or have an unusual appearance, odor, or texture, it's safer to discard them to avoid the risk of foodborne illnesses.
