单核增生李斯特菌Scott A和CA在23°C下承受2380 ~ 3400 atm的静水压力，副溶血性弧菌T-3765-1在680 ~ 1700 atm的静水压力。对于单核增生乳杆菌Scott A，与在磷酸盐缓冲盐水（100 mM, pH 7.0）中加压相比，在超高温处理（UHT）牛奶和原料奶中加压似乎提供了保护作用，并减少了细胞死亡。在23°C的UHT牛奶中暴露于3400 atm， 80分钟内杀死约106 CFU/mL的单核细胞增多l.s。在23°C的蛤汁中暴露于1700 atm， 10 min内可杀死约106 CFU/mL的副溶血性弧菌。
Listeria monocytogenes Scott A and CA, were subjected at 23°C to hydrostatic pressures ranging from 2,380 to 3,400 atm and Vibrio parahaemolyticus T-3765-1 from 680 to 1,700 atm. For L. monocytogenes Scott A, pressurization in ultra-high temperature-processed (UHT) milk and raw milk appeared to provide a protective effect and lessened cell death as compared to pressurization in phosphate-buffered saline (100 mM, pH 7.0). A population of about 106 CFU/mL L. monocytogenes was killed by exposure to 3,400 atm within 80 min at 23°C in UHT milk. A population of about 106 CFU/mL V. parahaemolyticus was killed by exposure to 1,700 atm within 10 min at 23°C in clam juice.
