An emergency supply of food should contain canned foods that have a longer storage life than fresh. Knowing which canned goods have the longest shelf life lets you know which foods you should replace or use in your food stores sooner than others. Having an emergency supply of canned foods on hand will only help in a disaster if the foods you have are still safe to eat.
