Do not freeze cheese because it dries the cheese and alters its flavor.
Cheese keeps best in your refrigerator.
If your cheese should happen to get some mold on it, don't worry; surface mold on cheese is perfectly natural.
Simply trim off the mold and the remaining cheese is still edible.
Wrap or seal cheese as tight as possible to prevent mold growth, making sure that you use a new, clean piece of plastic each time.
Try not to touch the cheese, as this will also help reduce mold growth.
