What is the the temperature of a refrigerator?

Answer 1

The ideal refrigerator temperature range is 1°-4.5°C (34°-40°F) . Bacterial and mold growth are considerably slowed down at these temperatures, thus retarding food spoilage. Since water freezes at 0°C (32°F), this prevents fresh foods from freezing, although when the temperature is at the low end of the range, some areas in the refrigerator may be below the freezing point.

Food poisoning bacteria grow rapidly in moist, warm food, at temperatures between 5 and 63° C. Most don't grow at temperatures between 0 and 4°C. So food is safe for short periods in the refrigerator (normal temperature between 2 and 4°C). But bacteria are not killed by cold; they simply remain dormant, and when warm again they come to life, grow and multiply rapidly.
