The inside of your refrigerator does not have the same temperature everywhere . There is usually a separate bin for fruits and vegetables. These bins are generally not as cold as the main part of the refrigerator.
Neither is the storage space on the door. It is really convenient, though, to store things that are used often on the door.
Do remember foods in both the refrigerator and the freezer are (ultimately) perishable and need to be properly wrapped to make them last. My old friend Roger was a great cook, but his refrigerator looked like a chemistry experiment gone wrong. When storing leftovers, they should get wrapped in plastic wrap or tin foil. Most leftovers should be eaten within two to three days or tossed. No point in taking chances!
