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).
The ideal refrigerator temperature is 35Â°F (1.6Â°C). You're not hugging the danger zone like you would be at 40Â°F (4.4Â°C), and you're distancing yourself sufficiently from 32Â°F (0Â°C) that you don't freeze half the stuff in your refrigerator.
