The sterile samples of pork were placed in polyamide-polyethylene pouches and inoculated with three-strain composite of C. jejuni (inoculum ca 10⁶ CFU x g^-1). The inoculated samples were sealed under vacuum and subjected to 200, 300 and 400 MPa of hydrostatic pressure for 5, 10 and 15 min. The number of surviving C. jejuni per gram was determined by the ten-fold dilution method followed by plating on Karmali agar. D₁₀ values were calculated. This work has shown that for reduction C. jejuni in vacuum-packed pork by 6 log units the application of 200 MPa for 46.15 min or 300 MPa for 4.27 min or 400 MPa is needed.
