Safety of canned salmon

Asked September 6, 2018, 8:25 PM EDT

I usually can all of my salmon in jars. A couple of days ago I sealed my salmon in cans and pressure cooked it. On some of the cans I can push the lid or bottom down with my finger and it bounces back. Would this be caused by a bad seal?

When the lid or bottom can be pushed down and bounces back, a vacuum did not happen during the processing. This is not a shelf stable seal.
