Abstract

Out of the total 232 analysed samples,12 (5,17%) were Listeriaspp positive., and
out of these latter ones 7 (3,02 %) Listeria monocytogenes stems, 4 (1,72 %) Listeria innocua stems and one (0,43 %) Listeria welshimeri stem were isolated. The presence of Listeriaspp was found in the analysed products in the following percentages: in pasteurised cows` milk 6,45 %, in cows` milk obtained from unpasteurised milk 4,25 %,in cream obtained from unpasteurised milk 6,66 %, and in fresh ewe`s curd 6,25 %. Listeria monocytogenes species was prevalent in the positive samples with a percentage of 58,33 %, while the other species were considered as having no pathogenic significance. Listeria monocytogenes was not isolated in the samples coming from pasteurised cows` milk and this makes us think that this thermal proceeding is efficient for destroying the listerias.
