The ideal temperature for your freezer is 0°F (-18°C) or lower. This temperature ensures that your food stays safely frozen and preserves its quality for an extended period. Freezing at or below this temperature stops most bacteria from growing and keeps food safe indefinitely, although long- term storage may cause freezer burn or changes in taste and texture
. It is recommended not to set the freezer temperature too low (colder than -18°C) because it can cause food to dry out and develop freezer burn over time, which affects quality
. Additionally, keeping your freezer about 75-80% full helps maintain a consistent cold temperature by retaining cold air, but avoid overpacking to allow proper air circulation
. In summary:
- Set your freezer to 0°F (-18°C) for optimal food safety and quality.
- Avoid setting it much colder than -18°C to prevent freezer burn.
- Keep the freezer reasonably full but not packed to ensure even cooling
