HIGH PRESSURE PASTEURIZATION is cold pasteurization in pure water; it uses ultra-high pressure purified water to keep seafood both shell and pathogen free. HPP is used in several segments of the food industry to inactivate foodborne pathogens such as Salmonella, Listeria monocytogenes, E.coli, Campylobacter species, and other vegetative pathogens. In the oyster industry, HPP provides an approved process for the inactivation of Vibrio bacteria which provides a high risk from the consumption of raw oysters and other shellfish. HPP helps producers increase food safety and extend shelf-life.
