How long are canned goods good for?
My s/o insists that canned goods last forever. I've had old canned goods that have tasted like metal. He has some cans that are so old there is rust on the outside. I say 2-3 years and they need to go. How long will the food stay good and how long before it gets risky?
People, the older cans did not put an expiration date on.

There is typically a date code that is not readable. Copy it down and search on the product company's website of how to read the date code. All are different and depends on how acid the food is and if the inside of the can is coated.
A date code doesn't look like a date... it is a long list of numbers and letters... no way to figure them out with out help from the vendor. They do this for "recall" purposes and required to do it by law.
For instance :H7C21 LYxDD is 08/21/97 and will expire in 48 months.
H = the month, A=1, B=2, etc.
21 = the day
H7 = 97
As you can see, even if you knew the key, you woudn't know if that is 2007 or 1997
Here is an old place you can get an idea... for newer items you have to go to the manufacturer webiste. BTW, Tuna last for 5 years and some Corned Beef last forever.

Depends on what kind of foods. But generally just follow the (Use By:) date on the can not the (Sell By:) cuz they are two totally different definitions. Also if the top of the can is bulging or popping out it means bacteria has formed inthe food and is dangerous to the consumer u may get food poisioning or something you won't enjoy.
