How Many Years Can Canned Food Last?

Canned food is a convenient and economical way to stock pantries and make meals. Many people wonder how long canned food can be safely stored before it needs to be thrown away. The answer depends on the type of food, the storage conditions and how it was canned.

Most canned foods have an expiration date stamped on them. This date is an indication of when the food was packed for sale, not necessarily when it should be used by. Generally, high-acid foods like fruits, tomatoes, and pickles will last between 1-4 years from the date of packing; low-acid foods like meats and vegetables can last up to 5 years or more.

Proper storage is also important for maximising shelf-life. Canned food should always be stored in a cool, dry place out of direct sunlight. If cans become dented or damaged in any way, they should not be consumed as this could lead to bacteria growth.

The method of canning also affects shelf-life; double seam cans are believed to have a longer shelf-life than single seam cans because they create an airtight seal that is less likely to break down over time.

Conclusion:

When properly stored, canned food can last up to 5 years or more depending on the type of food inside and how it was canned. While most canned goods will have an expiration date marked on them, this is only an indication of when it was packed for sale; if it remains unopened and stored in optimal conditions, it can remain safe for consumption for many years beyond this date.
