Low-acid foods, such as vegetables and meats, require pressure canning. Food preserved by canning or bottling is at immediate risk of spoilage once the can or bottle has been opened. Lack of quality control in the canning process may allow ingress of water or micro-organisms.
Pressure canning is the only safe home canning method for meats and low-acid foods. This method uses a pressure canner — similar to, but heavier than, a pressure cooker. A small amount of water is placed in the pressure canner and it is turned to steam, which without pressure would be 212 °F (100 °C), but under pressure is raised to 240 °F ...

Salt-curing processes were developed in antiquity [9] in order to ensure food safety without relying on then unknown anti-bacterial agents. The short shelf life of fresh meat does not pose significant problems when access to it is easy and supply is ...
The purpose of IMF foods is to achieve a water activity that the food can be stored safely without refrigeration. However, the food is not sterile. Staphylococcus aureus is a microorganism of concern as it can grow and produce specific enterotoxins in water activities of 0.83-0.86 under aerobic conditions. [2]
