Bacteria are the most important microorganisms to the food processor. Most are harmless, many are highly beneficial, some indicate the probable presence of filth, disease organisms, spoilage and a few cause disease.asteurization, the destruction of vegetative cells of disease-producing microorganisms, consists of a temperature of 140Â°F for 30 minutes, or about 161Â°F for 16 seconds. Yeasts, molds, and the vegetative cells of spoilage bacteria also die at pasteurization temperatures.
