| Outline of Final Research Achievements |
One hundred and forty-nine of Listeria monocytogenes (LM) strains isolated from the food and the food-processing plants were classified by genetic analysis (PFGE and MLST). We detected LM and free-living amoebae (FLA) in 81 swab samples obtained from the three lightly-pickled vegetables processing plants. As the result of this, we specified some genetic types of LM which were consistently detected from several foods processed by different manufacturers. Three swab samples from two different plants detected both LM and FLA, of which two samples were from packaging machines.
