At what point should I throw away my food storage and start from scratch?

Here's where we want to remind you that YOU ARE SMART! Storing food follows simple common sense. If a can of peaches has mold growing on the top, or if a can of tomatoes is bulging, that's a pretty good indication that the food isn't edible. If your food looks and smells fine, chances are pretty good that it is fine! If you're worried about things that you can't see or smell, just cook the food thoroughly (make peach cobbler!). Even dangerous micro-organisms can't survive the heat!
