Oven Canning - UNSAFE

Orange City, Iowa- Preserving food by canning in the oven has been a hot topic this summer. It seems everyone is looking for a shortcut to preserve food at home. 

Oven canning is NOT a safe shortcut. Katie Knobbe, nutrition and health specialist and a master food safety advisor for Iowa State University Extension and Outreach says, “Many individuals have shared they have tried, or have heard about, oven canning. 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.”  

Very often, a trusted and well-meaning friend or relative has shared information about canning in the oven as a simple way to can food. Others have found information off the internet promoting it as a “quick and easy” method.

Food “processed” in the oven will not necessarily be heated hot enough or long enough to produce a safe product.  Oven regulators may not be very accurate and the hot air in the oven may not circulate efficiently enough to heat the food in the jars. In addition, dry heat penetrates jars very slowly. Canning jars are not designed for dry heating either. Who would want to clean up that mess if they exploded? 

In addition, think of the wasted resources when finding out your food may not be safe to eat.  Knobbe adds, “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.”

Learn more about safe food preservation by participating in a Salsa Workshop on Sat., August 24 at the American Reformed Church in Orange City.  Participants will do hands on canning and leave with a jar of home canned salsa.  Online registration and pre-workshop ‘homework’ is required.
