I have some store bought canned goods (Just started canning/prepping). Some dates on cans are not far off. Can I open and can again in mason jars to make these last longer? Is there a canning guide that tells how long certain foods will last?

eat it and buy new

by the time you buy a new lid you can almost buy new canned goods

good lids right now are 5 dollars a dozen

the date on the canned good is a best if used by date , it will be safe to eat till the can rusts or bloats , it will just diminish it taste and quality

those dates can usually if storage has been cool and dry extended by 3-4 years easily

you are going to loose taste and quality re-canning , unless you say have flats of tomatoes 2 years past the date and want to make chili then re-can , heat breaks down food , plain and simple the only way to re-can is to use a bunch more heat

your not likely to do better than the seal on those original factory cans

your looking at >50 cents a can to re-can just in supplies if you have clean jars , if you don't have jars a lot more it is Much cheaper to use it and buy new factory canned food.

Re-canning isn't going to extend the shelf life, and the heat of processing may well diminish the available nutrients in the food.

I'm with @GREENCOUNTYPETE: use the older dates in rotation, replace with fresh stock.

Re-canning won't set back the clock, as a matter of fact it will speed up the process. Feed it to the hogs or chickens, and buy or put up some fresh stuff

I'm pretty sure we had this discussion a few days ago with another new poster.

Not exactly the same circumstances but the same question.

I did a quick search, and yes I'm logged into my affiliate account- that link goes back to that. So if you buy it, I make a commission, and I get to put some more pennies in the jar to feed my horses. LOL
But I did find it under the search terms - USDA complete guide to canning for 2022 - Actually a whole page of stuff pertaining to that. I like physical books, myself. What if computers die? I'm sure they'll tell you to throw it out. They're always uber cautious like that. Me? I grew up with Grama water bath canning deer meat and I drank raw cows milk as a sickly preemie newborn. I'm obviously passed from this planet into the great beyond. LOL

Yes we did , different reason for the same thing I guess

let me say it again

Eat what you store , Store what you eat

rotate and use

if a can on the shelf gives you a warm fuzzy feeling , it won't when the contense is warm and fuzzy and inedible or worse.
