The sterilization of the livestock’s internal organs  by using high pressure

Here is a specific verification result: after E. coli, salmonella and golden staph were planted into beef liver, the liver was applied each pressure and then measured the survival number of them in it. In the case of 105~107CFU/g of germs, E. coli and salmonella could not be detected any more in 90 minutes (by 300MPa), 60 minutes (by 400MPa) or 30 minutes (by 500MPa), and golden staph in 30 minutes (by 600MPa).
