Food preservation and canning troubleshooting guide

Why didn't the lid seal? How do I keep my peaches from floating? Many problems with home canned products can be traced to use of other-than-recommended canning equipment or procedures. Current food preservation fact sheets and publications are available from the National Center for Home Food Preservation website.

If you are using recipes and/or procedures written before 1994, you are using outdated materials. For safety's sake, please update your methods.

Checking your equipment and reviewing current canning recommendations can go a long way towards preventing potential problems. This "troubleshooter's guide" may help you determine the cause of the problem and how you can prevent it from happening again.
