How should low-acid foods be canned?

Low-acid foods require processing in a pressure canner to reach temperatures high enough to destroy botulinum spores. The heat of a pressure canner (about 240–250°F / 115–121°C) plus the appropriate processing time ensures safety for foods like vegetables, meats, and other non-acid items. You must follow the canner’s instructions for time and pressure, and adjust for altitude, to guarantee a safe seal and proper heat penetration. Water bath canning can’t reach the necessary temperatures for these foods, and methods like microwave canning or non-canning devices aren’t safe or appropriate for ensuring sterility and proper processing.
