how cold should your freezer be
A freezer temperature of 0 degrees Fahrenheit or -18 degrees Celsius is recommended for food storage. However, when freezing food, -10 degrees Fahrenheit or -23 degrees Celsius is recommended.
The ideal temperature of a freezer should be around 0 degrees. The temperature should never get above 5 degrees.
It is recommended that your freezer stay at 0 degrees. Any higher than 5 degrees will shorten the shelf life of your frozen foods.
