Table 1.
Reduction in viable cell counts after 1 min 400 and 600 MPa pressure treatment. Table shows the average reduction in log10 (cfu/ml) of selected L. monocytogenes strains after 1 min at 400 or 600 MPa pressure compared to untreated control samples (n = 6 to 9 treated/untreated samples per strain). Standard deviation is shown in brackets
