A total of 54 (23 of ovine and 31 of goat) bulk tank milk samples from 10 farms in the Czech Republic were collected in years 2013 - 2014. The sampling was done at regular time intervals during the whole year, with five to eight samples collected from each of the 10 dairy farms involved in the study. All milk samples were collected into sterile sampling bottles and transported in a cooler sampling case to the laboratory for immediate examination. Farms were randomly selected to cover the whole area of the Czech Republic. The prevalence and characteristic of <em>Escherichia coli, Staphylococcus aureus</em>, <em>Salmonella</em> spp., <em>Campylobacter</em> spp. and <em>Listeria monocytogenes</em> was studied. Raw cow's milk can be contaminated by <em>E. coli</em> intramammarily during clinical or subclinical mastitis and either directly through animal feces or indirectly during milk collection through farm employees or the milking equipment. <em>E. coli </em>was detected in 90.3% of the goat milk and 95.7% of the ovine milk samples. The genes encoding Shiga toxins 1 and 2- (<em>stx</em><sub>1</sub>, <em>stx</em><sub>2</sub>) were not detected and no STEC was identified. The <em>Eae</em> was the detected in 3 (4.6%) isolates.<strong> </strong><em>S. aureus</em> was detected in 9 (29.0%) samples of goat milk and 8 (34.8%) samples of ovine milk. A total 12 (57.1%) enterotoxin positive <em>S. aureus </em>were obtained; 6 (28.6%) were positive for the production of<em> sec</em> encoding enterotoxin SEC; in 4 (19.0%) isolates the gene <em>seh </em>was detected; 2 (9.5%) isolates were proven positive for <em>seg</em> (4.8%) and combination <em>seg </em>and <em>sei</em> (4.8%). The presence of MRSA was not detected in the tested samples in our study. <em>L. monocytogenes</em> was detected in 1 (3.2%) samples of goat milk and 1 (4.3%) samples of ovine milk. The serotype (1/2a, 1/2b) was detected in our study. <em>Campylobacter </em>spp. and <em>Salmonella </em>spp. were not isolated from any of the samples. These results form the basis for determining the microbiological quality standards for goat and ovine milk.</p></td></tr></tbody></table> <!--[endif] --> |
