URBANA, Ill. - Preserving foods at home by canning is a great way to have fruits, vegetables, and meats year-round. A pressure canner is needed to process low-acid foods. Over time, calibration of a dial gauge on pressure canners can become inaccurate.
“If your pressure canner dial gauges are inaccurate, your foods may not reach the recommended pressure to be safely preserved,” explains Caitlin Huth, a University of Illinois Extension nutrition and wellness educator.
Testing of dial gauge pressure canner lids and gauges is recommended once a year for safety in the canning and preserving process. Before you start canning for the season, have your pressure canner tested at an Extension office near you.
