what should the temperature of a freezer be

The recommended temperature for a freezer is at or below 0°F (-18°C) . This temperature range is cold enough to keep food frozen and preserve it until it is ready to be cooked or reheated. Freezing food stops most bacteria from growing, and at this temperature, bacteria growth can be slowed down. However, the temperature of a freezer may need to be adjusted by a few degrees to account for factors like location, humidity, or outside temperatures. It is important to keep the freezer door closed as much as possible, especially during a power outage, to maintain the temperature. If the door stays closed, a freezer can keep food at an acceptable temperature for around 48 hours. It is also recommended to keep the freezer around 75-80% full to help retain cold air, but not packed, as food may block the internal air vents, making it harder to distribute cold air.
