Whether you're preserving your own harvest or you've purchased locally grown fruits or vegetables, canning, freezing and drying can be effective ways to serve foods that taste harvest-fresh at a later date. To ensure that the products you serve are safe, it is important to follow tested guidelines for safely preserving foods by these methods. Cooperative Extension offers both information and hands-on, small group training in a variety of home food preservation topics.
