Answer Each food and type of package has a different potential lifetime before it becomes unsafe or unpleasant to eat. In general, canned goods are intended to be used within two years, but most are safe for longer. Canned foods have been found that were scores of years old and had not become unsafe. Their quality does decline. Dry foods, like cereal, crackers, cookies, peanuts and potato chips do not usually become unsafe, but their packaging is generally not designed for prolonged storage - maybe six to twelve months. Soda in plastic bottles will lose some fizz after about six months. Water can probably be stored almost indefinitely. Canned meats and soups are like other canned foods. For canned foods to survive, the cans must be protected from corrosion. Low temperatures and low humidity generally prolongs storage life.
