Pathogenic bacteria in Finnish bulk tank milk

The aim of this study was to determine the occurrence of Listeria monocytogenes, thermophilic Campylobacter spp., Salmonella spp., stx-positive Escherichia coli (STEC), coagulase-positive staphylococci, Yersinia spp., and Bacillus cereus group in raw cow milk samples collected from bulk tanks at 183 Finnish farms. Additionally, the hygienic quality of the milk was studied by determining the total bacterial and Escherichia coli counts. Listeria monocytogenes was detected in 5.5% of the milk samples, with concentrations varying from  036-25.06.2013
