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.
This is because canned green beans have a much longer shelf life than do frozen green beans. Frozen green beans stay good between 12 and 18 months in the freezer. Experts say that low acid canned foods such as green beans are probably OK to eat up to 5 years.
