are my food jars still safe ?

I read about the causes. about siphoning. But finally again last nite I pressure canned that pumpkin cubes....... about less than 5 minutes after removing from canner, I noticed one quart of the seven had several inches of water missing..... then this morning noticed most of them had some water missing. Did the hot pack... I did not notice it previously in the pints I pressure canned several days ago. and one of the quart jar failed to seal so I refrigerated that one....
like happened in some of my yellow and green beans and apples earlier in the season
so is the food still safe even though the top of the products are not totally immersed?
thanks all

Did you adjust your temperature much during processing?
Adjusting too quickly is one of the biggest causes of siphoning.


RE: are my food jars still safe ?

As long as the food was processed at the current recommended time and temperature and the jars are well-sealed, the food is safe even if there has been siphoning.

But, if you're experiencing siphoning with a wide range of canned goods, the real issue is why it is occurring and how to prevent it.


RE: are my food jars still safe ?

Agree the food is safe. It may discolor but you can pitch that. But siphoning isn't normal and needs to be eliminated. That are many discussions here about it and how to eliminate it.


RE: are my food jars still safe ?

The problem is probably because I did not read that you left them in the pressure canner the additional 10 min. once the pressure is down to zero. You do not open the lid, just remove the weight or counterweight. Then, set the timer for another 10 min. That will help with the siphoning issue.
