Foram submetidas às contagens de microrganismos mesófilos, Staphylococccus coagulase positiva, e às determinações do número mais provável (NMP) de coliformes totais e de coliformes fecais, 60 amostras de leite cru comercializado clandestinamente nos Municípios de Botucatu e de São Manuel, Estado de São Paulo, Brasil. Os resultados obtidos evidenciaram a ocorrência de 41 (68,3%) e 50 (83,3%) amostras com contagens de microrganismos mesófilos e de coliformes totais, respectivamente, acima dos limites máximos estabelecidos pelo Ministério da Saúde para o leite pasteurizado tipo C. Evidenciaram, ainda, a presença de 30 (50,0%) e 11 (18,3%) amostras contaminadas por cepas de Staphylococcus coagulase positiva e por coliformes fecais, respectivamente. Apenas 5 (8,3%) amostras mostraram-se dentro dos referidos padrões legais.<br>Sixty raw milk samples commercialized without due authorization in the counties of Botucatu and S. Manuel, State of S. Paulo (Brazil), were submitted to mesophilic microorganism and coagulase-positive Staphylococcus and most probable number of total coliform and fecal coliform counts. Forty-one (68.3%) and 50 (83.3%) of the samples were found, respectively to contain mesophilic microorganisms and total coliforms above the maximum limits established by the Health Ministry for type C pasteurized milk. Thirty (50.0%) and 11 (18.3%) of the samples were found, respectively, to the contaminated by coagulase-positive Staphylococcus and fecal coliforms. Only 5 (8.3%) samples were found to comply with the required legal standards. The results showed the unsatisfactory hygienic and sanitary conditions of the raw milk and suggest the existence of great risk to the health of the consumers, especially when the product is taken without being boiled.
