Home gardeners can enjoy fresh food throughout the year by canning their produce; but 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.

Illinois Extension is offering free dial-gauge testing. Reserve your 15-mintue time slot by calling 217-782-4617. Free testing can be arranged on other dates year-round by calling 217-782-4617.
