Since the nineteenth century, canning has been one of the most common types of preservation techniques used in households. With advancing scientific discoveries, we now have come to the stage where we know how the canning can preserve food. By using established safe practices, various foodborne illnesses like, Botulism can be prevented.

For years, USDA approved canning techniques classes and workshops have been taught to our Maryland communities. With the growing demand in this area,  these classes/workshops are now an integral part of Grow It Eat It program developed by University of Maryland Extension.
