Hi Michael, 

Our events calendar for food preservation workshops across the state does not currently have a tuna canning class listed, but I believe two of our offices are figuring out details for offering such a workshop. If you are on the central coast, you can contact Stormi Dykes (<personal data hidden>) for details on a tuna canning workshop she is planning for late summer in Newport. If you are in the Willamette Valley, you can contact Jennie Gilbert (<personal data hidden>) for details on a possible class in the Eugene area.

Best, 

Jared
