What is the canning temperature range in Fahrenheit?

• A. 212 to 250
• B. 100 to 140
• C. 180 to 210
• D. 250 to 300

Answer: (A)

Canning safety relies on heating foods to temperatures high enough to kill harmful microbes and their spores. At sea level, the boiling point of water is 212°F, which is the standard heat reached in water bath canning. For foods that need a higher level of safety, pressure canners raise the internal temperature to about 240–250°F by increasing the pressure. So the range that covers both common methods is 212–250°F. The lower end reflects the boiling point used in water bath canning, while the upper end reflects the higher temperatures achieved in pressure canning to ensure safety.
