Abstract

During four-years period (1996-1999) qualitative-quantitative analyses of microorganisms in cow's milk through producing and processing stages were investigated. 840 samples (672 samples of raw and 168 samples of pasteurised milk) were analyzed in total. Analyses showed that total count of microorganisms varied among the samples. It ranged from 2.2 x 105 to 4.9 x 107 per 1mL of raw milk and from 2.3 x 104 to 4.3 x 104 per 1mL of pasteurised milk. Folowing species were isolated from raw and pasteurised milks: Staphylococcus aureus, S. epidermidis, S.saphrophiticus, Proteus vulgaris, P. mirabilis, P. morgani, P. rettgeri, Streptococcus faecalis, S. agalactiae, S. disgalactiae, S. uberis, S. bovis, Escherichia coli. 597 raw milk and pasteurised samples do not comply with current bosnian regulations. Among this number 34.37% contained Escherichia coli, 26.17% Staphylococcus, 21.89% Streptococcus and 7.28% Proteus species.
