Canned goods: Most expiration dates on foods in cans range from 1 to 4 yearsâbut keep the food in a cool, dark place and the cans undented and in good condition, and you can likely safely double that shelf life from 3 to up to 6 years. Frozen foods: Theyâre much like canned goods: pretty much expiration-proof.
As long as the container remains intact, canned foods have a long shelf life even at room temperature. 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.
