The best known pasteurized animal product is pasteurized fresh milk, where pathogenic (zoonotic) microorganisms (such as agents of Tuberculosis, Brucellosis or Listeriosis), if present, are destroyed, but spoilage bacteria may have survived. Pasteurized milk has therefore to be kept under refrigeration. In the meat sector, cooked ham in sealed and afterwards mildly heat treated plastic pouches, or sausages heat treated in casings, are examples for pasteurized products. The internal temperatures, for sensory reasons, should not exceed 72-78°C (see Fig. 118, 120). Refrigerated storage is therefore mandatory after processing.
