Combined treatment with both listericidal agents phage P100 and LAE reduced the L. monocytogenes populations by 3 log CFU/cm2 (Fig. 2). However, similar to their single effects, the combined mixture of phage P100 and LAE also failed to inhibit the regrowth of L. monocytogenes in storage and L. monocytogenes counts reached to 4.7 log CFU/cm2 at the end of 28 days at 4 °C. On the other hand, the combined mixture of listericidal phage P100 and listeriostatic PL–SD yielded the initial reduction of L. monocytogenes counts by ~3 log CFU/cm2
and following 28 days storage at 4 °C the L. monocytogenes counts were still lower by 3 log CFU/cm2
compared to the starting
