BackgroundIn Ethiopia, around 97% of the annual milk production is accounted by the traditional milk processing system using on-farm traditional milk processing materials that are generally poor in processing capacity, causing high product loss and risky for public consumption. A cross-sectional study was carried out in and around Gondar town, Amhara Regional State of Ethiopia from October 2014 to may 2015 with the objective to assess the bacteriological milk quality, possible hygienic factors and status of S. aureus as contamination of bovine raw milk. The study employed questionnaire survey and raw bacteriological load analysis and cow milk samples for isolation and detection of S. aureus from raw cow milk. Sixty (60) randomly selected dairy farms were interviewed for the survey-based study of farm hygienic practices and 72 raw milk samples [60 from directly from teats and 12 from collecting tanks (buckets) were aseptically collected and tested for bacteriological load analysis and isolation of S. aureus.
