Home Food Preservation

Home canning is an art and science that has been practiced for more than a century. With new scientific discoveries and technological developments, we now know principles involved in the canning process. Because of these scientific discoveries, USDA has created recommendations for the process of home canning. These practices, if followed diligently, can help home canners avoid many dreadful foodborne illnesses, even Botulism.

In order to encourage such sound practices, the Extension Educator conducts home canning classes. The classes not only involve knowledge delivery but also hands on experience of recommended canning practices. Follow the event calendar on the website for the scheduled classes.
