摘要：The zoonotic Listeria monocytogenes is mainly transmitted to human trough the food-borne route. This bacterium is often
found in the environment of food processing plants. In the period
2002-2004 it was studied the occurrence of Listeria monocytogenes. in 9 dairy
processing plants in 5 counties of Moldova territory. The aim of the study was
to identify the major sources and route for the dairy products contamination.
Among the 196 analysed samples of dairy products, 20,4% were identified as being
contaminated with Listeria spp., from which 3.57% with Listeria monocytogenes.
The highest frequency of Listeria monocytogenes contamination was registered in
raw milk (10.53%) and brining maturated cheeses (9.67%). There were analyzed 254
surface swabs. In 29.92% of samples it was noticed the presence of Listeria spp,
from which Listeria monocytogenes in 6.3%, especially in the raw milk reception
area (8.7%) The examination of working persons revealed that Listeria
monocytogenes was most frequently isolated from feces comparing with nasal
secretions and hands. This study indicates that Listeria monocytogenes is
commonly in the dairy industrial environment including food handlers. Correct disinfection
and hygiene will prevent or at least diminish cross-contamination of the
food-products.
