When was the last time you cleaned out your refrigerator and freezer? How about your kitchen cabinets (or pantry, lucky you if you have one!)?

Some foods, think produce and dairy, “announce” their expiration dates. Lettuce and other greens wilt, fruit rots, and milk turns sour. What about packaged foods, though, whether in bottles, cans, boxes, or bags? Besides, what about those leftovers or prepackaged meats and fish in your freezer? How long can you really keep those?
