Oven canning is unsafe

Preserving food by canning in the oven has been a topic of discussion this summer. However, oven canning is not a safe shortcut, according to Barb Fuller, nutrition and health specialist and a master food safety advisor for Iowa State University Extension and Outreach.

“Many individuals have shared they have tried, or have heard about, oven canning,” said Fuller. “Just because a jar is sealed doesn’t mean the food inside is safe to eat. I’ve had people say to me ‘I haven’t gotten sick from it.’ I tell them they are probably very lucky. Botulism is a big concern.”

When canning, use research-based methods and tested recipes for SAFE home food preservation. Iowa State University Extension and Outreach is a source of this information. Go to www.store.extension.iastate.edu for publications and recipes.

“People spend a great deal of money, time and energy canning food. It is disheartening to tell someone their (improperly) canned food could make someone they love very sick,” said Fuller.
