All freezers should be in the 0 to 8 degrees Fahrenheit (approximately -18 degrees to -13 degrees Celsius) range. However, when you first turn on the freezer, or put a lot of food into it, it may take up to 24 hours for the freezer to reach this temperature range.
Normally a domestic freezer is best set to â18 Â°C (0 Â°F) or colder, as that's what the expiration dates for many food items are based on. It's also a requirement for freezers in restaurants, supermarkets & other places that sell food (at least here in Europe) to maintain a temperature of at most -18 Â°C.A general purpose domestic fridge should be at around 1-4 Â°C (so, just above the freezing point, and below 5 Â°C).n order to keep food out of the Danger Zone, your fridge must be set between 32-40Â°F (0-4Â°C). Your freezer must be below 32Â°F (0Â°C). I keep mine as cold as it will go. Keep your freezer efficient by half-filling it with bottles of water.
