How long are home canned green beans good for? If one put up some this July what would the expiration date be?

Properly put up, they're good till the seal breaks.

No expert but if properly done I would expect they would last until next July.

Until the lid rusts through. Honestly.

I personally have had them for 7 years. That's not normal, usually 3-4 years here.

I have some 10 years old I would not be afraid to eat.

I have eaten 3-4 year old with no problem. As long as seal is not compromised they will be safe to eat indefinitely. But, taste and texture can suffer over time. The way they are stored makes a difference, especially in long term storage. Sun and/or freezing are no good.

I wouldn't know. My family don't let them last that long.

As long the lids are seal they will last as long you want them. cool dry place helps to have them last very long. I am talk about years not months

Back in 1967 my older brother picked up several gallons of wild plums from what we called the plum thicket there on the home place( Remember the year as it was when he left for college). Mom canned the juice in gallon vinegar jars and made jelly out of all but one jar, which for some reason she forgot about. We found it in the mid eighties and it was still sealed. We opened it and as it still smelled good mom made jelly with it. The jar lids were thicker back then and had better sealing rubber on them in my opinion. This was just and interesting story. And no one cans in gallon jars now days.

I've got jars of grape jelly in my basement that are 8-10 years old still good. As others have said if lids are sealed and no rust your usually good to go. I'm actually going to go threw the jars of jelly here in next few days and sort them.. Have so many because my daughter was working at a friend of her's vineyard and got buckets of different types grapes. Ended up with more pints jelly than we would ever use and actually got tired of it. I've popped a few open and their still good. Some the sugar has started to go back to crystal in some though. I'm going to use them on bear bait and find something else to put in the jars.

Mine are 2 years old right now.

Until the lid seal is lost. Some food, like carrots, will lose a little of it’s color over a period of several years. A friend of mine had a quart jar of green beans on display in his kitchen that were canned in the 1930’s...they still looked great. I opened a jar of pickled beet last week that my wife canned in 2009.

In 1987, my uncle and I were preparing my grandparent’s house for an estate auction. In the basement we found several quarts of venison, with a piece of masking tape on the lid that were marked 58. My uncle fried that 29 year old venison for supper that night, tasted great.

keep them in a cool spot and check the seals often no problem especially with beans. Foods that are acidic in nature berries fruits and tomatoes be careful they they tend to compromise the lids faster. Myself I have went to blanching veggies and vacum package, faster and not as expensive.

My mother passed away in July of 1996. I have 2-3 quarts of her homemade mincemeat yet. I ate a quart of it a couple years ago and it was still great tasting. As stated above, if canned correctly, and still sealed, it should be fine. I've had store-bought canned veggies 10+ years old that were fine too.

I've got cans of sockeye salmon I put up 30 years ago using a pressure cooker and can sealer when in Alaska. The cans are not rusty or swollen, are they still good?

Green beans tell you when they are bad. Will smell bad and liquid will be cloudy. Lid will bulge. Jar may burst.

I have yellowfin tuna that is several years old without a problem Nothing in jar but tuna cooked at 11lbs for 100 minutes. I use sterile pint widemouth jars.

I would imagine if the seal is intact the contents would still be sterile and safe. However, palatable may be another issue as quality may have broken down with time. This may be particularly true if the jars were stored exposed to light and/or heat.

I wouldn't think light would be as hard on the canned goods as it is on jarred goods. In the jars there is a kind of greenhouse effect if left in the sun, as well as UV exposure.

Do you remember where you got the can sealer Paul? I've always wanted to put some stuff up in cans.

If not....you got some fine mink bait there Boss.
