Will bottled feta cheese go bad if not refrigerated?

The information I uncovered says yes you do have to refrigerate cheese in oil after it's open. Place the sliced pieces of cheese into a glass jar, cover with a neutral oil like sunflower if you are doing this yourself with a wheel of cheese. Then wax paper and a rubber band for the top. If you are buying cheese already in oil, make sure the top is replaced with the wax paper and rubber band once the seal is broken.
