The expiration date on canned food items is usually printed on the top, bottom or side of the can. Canned foods have a very long shelf when stored properly.
On average, canned meats, tuna and vegetables have a shelf life of 5 years. Fruits and vegetables, including canned tomatoes, have a shelf life of 1.5 to 2 years.
Some canned foods may not have listed expiration dates. However, the cans may be stamped with a best-by date or sell-by date.
Over time, canned food can lose its texture as well as taste. Keeping canned goods in a cool and dry location aids in extending its shelf life. If canned foods leak or begin to bulge they should be discarded. Likewise, if the food gives off a foul odor or has changed in texture and color it should not be consumed.
