Canning is an excellent way to preserve leftover fruits and vegetables from your garden. Canning isn't without risks, however. Improper canning using unsterilized canning jars can be a recipe for a health disaster. According to the USDA, canned food may grow the bacteria Clostridium botulinum, which is the cause of a dangerous form of food poisoning called botulism. While using a pressure cooker is the recommended method of sterilizing jars, there is another safe method that is equally as effective.
