Therefore, you want your refrigerator to be cold, but not so cold that it freezes things. The preferred temperature is somewhere between 35 and 38 degrees F (1.7 to 3.3 degrees C).Anything higher and foods will spoil too quickly (it also presents food poisoning problems, as described in several of the links below).If you have read How Food Preservation Works, then you know that the purpose of a refrigerator is to slow down the growth of bacteria. The purpose of a freezer is to stop bacteria completely by freezing them solid.
Average temperature of a refrigerator is 35 - 38 degrees and -18 Â°C (0 Â°F) for the freezer. A household refrigerator should be maintained between 34 and 40 degrees Fahrenheit-just above freezing to maintain food quality but low enough to inhibit bacterial growth.Ideally your refrigerator should be at the correct temperature (less than 4Â°C). When the fridge is very full, turn thermostat to Colder setting.reezer temperature should be maintained at minus 18Â°C. (Ice cream is a good indicator of freezer temperature: it should be firm.) Consult your fridge manufacturer's manual for advise on temperature control. Try not to keep opening the fridge door every few minutes.
