I am in the process of refreshing my canned foods so I am trying to eat all my older stuff, skipping the outliers like 2003 and 2004 foods, here are some best by dates on the regular products that I am currently eating that are all perfect.
Blackeye peas July, 2008.
Mixed vegetables March, 2010.
Green beans July, 2010.
Tomato sauce March, 2010.
Albacore tuna, January, 2011.
Corned beef January, 2008.
This is my normal treatment for these kind of things, although I live in a hot climate I have learned that for most canned goods, a few years past the “best by date” doesn’t matter in any way.
That matches up with our experience, although our climates differ. Everything gets stored inside the house at stable temps. Most of it will be good for a decade or more I expect.
