Left jars in canner overnight and re-processing - are they safe?

[Rockergirl]

Hi. I made a mistake and fell asleep before my canning round ended....I used a presto electric canner (I know there are debates on those, I've done tons of research and I'm comfortable using for the short run - I use both stove top and electric (this when doing larges batches and want several pots or small batches....) Anyway - I fell asleep. I only had 3 quarts that I was processing. Only one of them sealed (not sure why, could be leaving in the canner) - is the one can that sealed safe, even if it was left in an enclosed canner all night? It was not hot but really warm still when I woke up. Also, assuming they were safe, I reprocessed the other two.....since they were still really warm, I kept them in their original jars and only replaced the lids. They sealed. Are those safe, not boiling again, just going straight from staying overnight in the canner and reprocessing right away, before 12 hours? They got much darker in color the 2nd round....

I don't know the answer.
I thought I read that reprocessing within 12 hours was okay.
What are you canning?

Reprocessing Unsealed Jars​

If a lid fails to seal on a jar, remove the lid and check the jar-sealing surface for tiny nicks. If necessary, change the jar, add a new, properly prepared lid, and reprocess within 24 hours using the same processing time. Headspace in unsealed jars may be adjusted to 1½ inches and jars could be frozen instead of reprocessed. Foods in single unsealed jars could be stored in the refrigerator and consumed within several days.

So you are good.

It was chicken broth.

Perfect! Thank you! Do you happen to know whether it's safe after leaving jars in the canner all night? I was worried that maybe them sitting in a warm environment like that overnight might create some sort of weird bacteria? I guess if the 1st one sealed, it would be protected from that and when I reprocessed the other ones, any issue would be "cooked" out during the process....

I can't find an answer to leaving the jars in the canner overnight, on nchfp. Reddit has some discussion there. A few other canning blogs.

Leaving in the canner overnight can but does not always create a 'flat sour'.

Flat Sour

Flat sour is an unappealing off-flavour that canned goods, home or commercial, can develop. It's caused by keeping jars of just-processed food warm too long after processing.

This is created by heat loving thermo-type bacteria.
This is not risky to food safety, but you might want to taste it and see if it is good tasting to you. Safety wise, you are good.

Also, I don't have the approved electric canner but I'd feel safe using it with all the regular canner rules.

Perfect, thank you!!!!! I did wonder about the taste too, but knowing that it is at least safe, I feel safe tasting it. I'm pretty bummed I did this....I timed it and knew it would be a later session but told myself I was fine to stay awake....I won't do that again. That's the one problem with the electric canners. You have to wait about 1-1.5 hours of cool down time, before you can open the canner. Which is great in some ways but not when you are canning in the evening....

Great!
My old pressure canner takes about 45 minutes to cool down naturally when it is full.
At one point I canned 4 sessions in a day, dry beans to canned beans. It was exhausting and I fell asleep before taking the last batch out. I worried about it for a good long while, but they were fine.
