The evaluation of microbiological contamination of milk is one of the important parameters to determine their useful life, ensuring health of consumers. The objective of this study was to evaluate the microbiological physicochemical characteristics pasteurized milk sold in the municipality of Uberlândia and compare them with the standards established by law. It was analyzed 18 samples of three brands of pasteurized milk collected in the municipality of Uberlândia-MG, held at the Laboratory of Quality Control of Food Safety, Faculty of Veterinary Medicine, Federal University of Uberlândia (LCQSA / FAMEV / UFU ) in March and April of 2009. It was observed that the analysis of alkaline phosphatase, peroxidase, density and acidity showed normal values for all samples. For other physical-chemical analysis, the values were not satisfactory, 6 samples (33.33%) and 9 samples (50%) had results below the minimum required by law for fat and dry extract respectively. The total dry extract, 11 samples (61.11%) were with values outside the current standard. In the microbiological analysis for enumeration of aerobic mesophilic bacteria, 7 samples (38.88) results were above the maximum permitted by law, total coliform showed 13 (72.22%) and fecal coliform 8 samples (44.44%) were outside the permitted standard. It is concluded that in general the quality of type C milk sold in the municipality of Uberlândia-MG in the period examined was not satisfactory, or not as the rules especially the microbiological analysis.
