Sausage samples aretaken from four areas in Denpasar (North Denpasar, East Denpasar, West Denpasar, and SouthDenpasar). From each area, three traditional markets are selected and from each market 2merchants are chosen. The calculation of the number of Staphylococcus aureus is done byplatting method and by pour plate method. The results show that the highest number ofStaphylococcus aureus belongs to the North Denpasar region in the mount of 241,067 CFU/gwhile the lowest belongs to the region of West Denpasar with 71,233 CFU/g. These two resultsare significantly different with one another (P<0,05). The maximum limit of microbialcontamination in processed meats (sausages) for Staphylococcus aureus based on IndonesianNational Standard (SNI) is equal to 102 CFU / g.
