How long does beef jerky last if it is dry canned?

Dry canning, a form of home canning or food preservation, should generally not be used for preserving meat including beef jerky, regardless of its low moisture content.

This is because dry canning creates the perfect conditions for the germination and subsequent toxin production of the deadly bacterium *Clostridium botulinum*. It's crucial to preserve low-acid foods like meat via methods like hot water bath canning or pressure canning, using scientifically tested recipes and safe processing techniques.
