How do you keep hot dogs safe to eat?

• These times assume the fridge is at 40°F or colder and the freezer at 0°F.
• Freezer times are for best quality. Food kept frozen at 0°F stays safe indefinitely; it just loses flavor and texture over time.
• Perishable food shouldn't sit at room temperature for more than 2 hours (1 hour above 90°F).
• Smell and looks don't tell you about the bacteria that make people sick, so go by the time, not by a sniff test.
