The sealed containers prevent contamination of food by organisms that can spoil the contents or cause illness to people. While canned foods do not change suddenly, slow changes do occur in the container and food quality may change over time. The storage life depends on a number of factors, including conditions of storage and the nature of food. As a general rule, the best shelf life will be obtained when canned foods are kept in a cool, dry place. For best results, it is recommended that your supplies of canned food are refreshed periodically.
