The thing strangest about fasting is, that once you stop, each time you go to eat you question yourself if you should. It takes a few weeks before the habit of eating becomes "NORMAL". I stopped fasting, but still have plenty of fresh oranges to last another month+ and still drink 1 quart each night for my water source.
A quality well grown orange seems to store for 2-3 months before it will dry up. Maybe 1-2 oranges per case will mold and most likely were damaged in the handling process that allowed fungus to penatrate the natural oranges defenses.
