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.
Practically âBest beforeâ dates are often simply suggestions for consumers, but they donât indicated when the food will turn inedible. This means that canned meat, for example, may have an average shelf life of 7 years, but have a âBest beforeâ date of 1 year after canning. Itâs still perfectly edible on the 7th year. And as we already mentioned, its life is much longer if stored properly.
