Pressure Canner Testing Clinic | Marshall-Putnam

Pressure canning is important when canning low-acid foods, particularly meats and vegetables. Illinois Extension recommends home canners have their dial-gauge pressure canners tested at least once each year to see if the needle is accurate. Over time, the needle on a dial-gauge pressure canner can become inaccurate. If the dial-gauge is not measuring the correct pressure, foods inside the pressure canner may be under-processed, which increases the risk of serious illness from botulism.

· We offer free testing for dial-gauge pressure canners.

· Testing often takes about 15 minutes per canner

· During testing clinics, you can stop in or drop off lids with gauges ahead of time

· It’s well worth the visit to know what the gauge reads
