Fridge and Freezer Temperature

35 degrees Fahrenheit for fridge and lowest possible temperature for freezer. References: Life Hacker and U.S. Food and Drug Administration.

It does bother me a little that my refrigerator at home allows temperatures higher than the upper limit of 40 degrees Fahrenheit, where food can go bad much more quickly. Lesson learned here: if there are knobs to tweak, always figure out what they do first then set reasonable values.
