Abstract


One hundred twenty samples of raw and pasteurized milk collected from different points of a processing fluxogram in a type A mini processing milk plant were submitted to the countings of mesophylic microorganisms and to the survey of total coliformes, fecal conforms and Staphylococcus aureus. In spite of all analized samples showing to be negative in relation to the survey of S. aureus, the obtained results showed that 78 (75,0%) milk samples collected from the raw milk tank, as well as 6 (25,0%), 8 (33,3%) and 11 (45,3%) pasteurized milk samples collected from the storage tank, balance tank and outflow of the botteeling machine, respectively presented to be out of the legal microbiological standards.
