A recent foodborne illness resulting in the hospitalization of 20 people including one death is being linked to a home canned food. This is a stunning reminder that home canned foods have a real potential to cause severe illness. That does not mean you should not can foods at home but means that you must be using scientifically based methods. Start this season off right by reviewing credible research based information.
