Does pressure cooking kill bacteria.

Bacillus cereus strains vary in their heat resistance, post-processing survival and growth capacity in foods. Hence, this study was carried out to determine the effect of cooking on the survival and growth of eight B. cereus spores in rice at different temperatures in terms of their toxigenic profiles and extracellular enzyme activity. Samples of rice inoculated with different B. …Cooking contaminated food at recommended temperatures destroys the vegetative cells of B. cereus. Heat-resistant endospores of this bacteria are more likely to survive cooking and start growing again (germinate) when the food is cooled gradually over an extended period of time. The emetic toxin (cereulide) is heat stable up to 121ºC (250ºF)Canning spaghetti sauce with meat using the water bath method is unsafe. Because meat is a low acid food, it can harbor bacteria. This bacteria is tough enough to survive the water bath canning method. Because of this, the only safe way to process spaghetti sauce that contains meat is with the use of a pressure canner.This makes it easier to use other cooking methods.
