Quick Answers

 

 

I'm moving out West and I'll be taking many home-canned foods with me. Will I have any problems with jar seals when I move them to a higher elevation?

 
As long as foods were properly canned and a good vacuum was achieved, you should not have any problems. If jars have a weak vacuum, they can lose their seal if moved to a higher elevation. If this occurs, discard the food.
