The Human Milk is considered the most complete food for the newborn, to promote the collection and distribution with certified quality, the Ministry of Health in the public policy scenario promotes breastfeeding and expansion of the Brazilian Network of Human Milk Bank which was created to ensure certification and the quality of human milk from collection to distribution, it is responsible for the selection, physicochemical and microbiological evaluation, providing an innocuous product and respecting their role as food. To contribute to the scientific evidence this study was to evaluate the microbiological quality of samples of human milk from milk bank in São Carlos / SP, through analysis and quantification in petri dishes by solid culture of mesophilic, psychrophilic, thermophilic, Staphylococcus spp. filamentous fungi and leveduriform and most probable number (MPN) of total and fecal coliforms through presumptive test and confirmatory, as well as verification of physical-chemical parameters of pH, acidity ° Dornic and energy content (K) correlating the variables in the microbiological quality by descriptive statistical analysis and linear correlation Pearson. Of the 29 analyzed samples and unfit for consumption, revealed the presence of 17.24% of psychrophilic, 27.59% of thermophiles, 55.17% of mesophilic, 41.38% of filamentous fungi and leveduriform absence of Staphylococcus spp, for coliform group was the presence of 82.76% presumptive phase and 54.16% for total coliforms and 33.33% for fecal coliforms in the confirmatory phase, pH values and K showed no variation, as for acidity was microbial growth between 3 ° to 15 ° Dornic, the correlation of physical and chemical variables was detected. The results presented in analyzes suggest that was deficient in good manufacturing practices, impairing the microbiological quality of human milk.
