NORMAN — The Cleveland County Extension Office, 601 E. Robinson St. in Norman, will check dial pressure canner lids for free.
Those interested can call 321-4774.
The canner dial must maintain accuracy and if it is off more than two pounds, it must be replaced.
If a product is underprocessed because the dial reads too high, spoilage or foodborne illness can result.
Individuals with weighted pressure canners must check the gaskets or sealing rings, the vents and safety valves each year.
The same must happen for dial gauges.
Only glass jars that have been tempered for heat and cold should be used in home canning.
The two-piece lid, consisting of a flat disc with sealing compound around the outer edge and a separate metal screw band, is the most common type of lid available.
Don’t use canning recipes older than 1988.
