Oranges--some info for you and info about the ANR Publications:
Oranges: Safe Methods to Store, Preserve, and Enjoy!
I was looking for safety cautions for handling, storing, and preserving oranges and came upon this very helpful UC ANR Publication. It is Publication 8199 and is available for download at:
There are many publications related to canning and food preservation at this link. Take a look and you might find some interesting reading and learn more about how safety methods that we as Master Food Preservers should instruct the public.
My goal for becoming a Master Food Preserver is to teach the public about food safety when canning and preserving. I hope to gain more understanding about food safety through resources such as UC ANR.
