Now is the perfect time to ensure your pressure canner is working properly!
The USDA recommends pressure canners with dial gauges be tested annually. Why? Testing the gauge tells you whether your gauge is working properly. An accurate gauge is necessary to make sure your home canned foods are safe. Only dial gauges need annual testing. Weighted gauges stay accurate unless they are damaged.
Pressure canning is the only recommended method for canning meat, poultry, seafood, and vegetables. The risk associated with these low-acid foods is botulism poisoning, if they are not processed properly. Only pressure canning will allow food to be heated to and held for a specified time at 240 degrees Fahrenheit which is hot enough to destroy the bacterial spores that emit toxins.
Free Gauge Testing Available

Dial gauges like this one need to be tested every year to ensure accuracy.
Weighted gauges are usually designed to “jiggle” several times a minute or to keep rocking gently when they are maintaining the correct pressure. Weighted gauges like this one do not need tested.
Always check rubber seals and safety plugs regularly for wear and cracks and replace if necessary.
