In general, high-acid canned foods such as tomatoes, grapefruit and pineapple can be stored on the shelf 12 to 18 months; low-acid canned foods such as meat, poultry, fish and most vegetables will keep 2 years -- if the can remains in good condition and has been stored in a cool, clean, dry place.
Storing foods in high temperatures can make them spoil, even while sealed.
Even if they are a few years old, the quality may not be as good, but as long as they were properly processed to start with, they will still be safe.
