A pressure canner is a very important piece of equipment when it comes to home food preservation. Making sure it is working properly is a precaution that should be taken seriously. If the dial gauge on your pressure canner does not register correctly, you could be jeopardizing the safety of the food you just canned. To avoid any issues with the proper function of your pressure canner, you need to have it checked. OSU Extension, Darke County will check dial-type pressure canner gauges by appointment on June 6th, from 8:30-3:30 pm at the OSU Extension Office, Darke County.
