Hi Elizabeth,
OSU Extension has many publications available to learn about food preservation and safety. Remember to use up-to-date, tested recipes from reliable resources when canning. You can find our food safety and preservation resources at: https://extension.oregonstate.edu/food/preservation.
This page has a link to upcoming workshops and events throughout the state.

You can also contact our Polk County Extension office directly to find out what programs they have coming up.

Thanks for contacting Ask Extension.
