Does pressure cooking kill bacteria.

Many species of spore-forming bacteria are associated with food spoilage (Gould, 2006; Stragier and Losick, 1996).Bacterial endospores, especially Bacillus species, are the inactivation target in various forms of food processing. One of the most important microorganisms as significant pathogens in humans or involved in quality damage, …Mold spores die at temperatures of around 140-160 degrees Fahrenheit or at temperatures below freezing. Water boils at 212 degrees Fahrenheit. So, naturally, boiling water is at a sufficient temperature to kill mold spores. Cooking in an oven, pressure cooker, or any other cooking machine will kill mold spores as long as it reaches at least 140 ...Temperatures between 40°F - 140°F allow rapid growth of bacteria, yeast, and molds. 95°F. Maximum storage temperature for canned foods. 50 to 70°F. Best storage temperatures for canned and dried foods. 32°F. Temperature water freezes. 32 to 40°F. Cold temperatures permit slow growth of some bacteria, yeasts, and molds.Bacteria produce toxins that make people sick, it’s not just the existence of bacteria themselves. Bacteria grow in ideal conditions (if they have food, moisture, the right temperature and acidity). You can kill bacteria by cooking, but you cannot cook out the toxins they leave behind in the food either by growing or dying there.
