In contrast, these numbers were realized after only 7 days incubation at 10 °C. In both cooked turkey and roast beef, the L. monocytogenes numbers exceeded the 2 log10 CFU/cm2 after 10 days and 3 days at 4 and 10 °C, respectively. Treatment of the cooked turkey with phage LISTEX™P100 reduced the L. monocytogenes counts by 2.1 log10 CFU/cm2 to a minimum level of 1.3 log10 CFU/cm2 after 2 days storage at 4 °C.
