Why did my canned green beans spoil?

Your jars simply have acquired some mineral deposits. This happens either when you’re canning in hard water or when your canning pot/rack is starting to break down.

What happens if you pressure can too long?
Technically, pressure canned food is good as long as you have a solid seal on your jars. Whether that’s one year or ten years, the food inside will be safe to eat as long as that seal has remained. That being said, the flavor and nutritional profile will begin to degrade after a year on the shelf.
Can you reprocess canned green beans?
Canned food can safely be re-canned if the unsealed jar is discovered within 24 hours. To re-can, remove the lid and check the jar rim for tiny nicks. Change the jar, if necessary. Add a new treated lid and reprocess using the same processing time.

- A lid that has lost its seal.

If the cloudiness disappears the problem was probably residue from canning in hard water, and these jars may be used for future canning. However, if the cloudiness remains, it could be a sign of soft water etching or scratches remaining from use of metal utensils. These jars are more likely to crack during canning.
