Dial pressure canner gauges need to be tested once a year. Over time, a dial gauge’s calibration can become inaccurate and show an incorrect pressure. If the pressure is even slightly lower than recommended, the internal temperature of the food will not be high enough to kill all the bacteria, and harmful toxins can build up and cause illness or death.

To get your pressure canner dial gauge tested, drop off your lid at the Livingston, McLean or Woodford County Extension office. Once the lid is tested, you will be contacted about the results and for pick up.

Pressure canner testing is available at other Extension offices around the state as well. For more home preservation resources, visit the state Nutrition and Wellness page.
