A 4 log reduction of L. monocytogenes inoculum was observed in
the olive homogenate of both cultivars after 30 min in industrial processed
olives, whereas in olives fermented by OSC in reduced salt brines
the population of the inoculated pathogenwas under the detection limit
after 10 h for both cultivars fermented in Brine A or Brine B. In green olives
Chalkidikis the population of L. monocytogenes was under the detection
limit after 8 or 10 h in olives fermented by OSC in Brine A or
Brine B, respectively. In industrial processed black Kalamata olives the
population of L. monocytogenes was reduced by 6 logs after incubation
for 8 h at 30 °C whereas in green olives Chalkidikis L. monocytogenes
was reduced by 6 logs after 2 h of incubation at the same temperature
