The aim of this study is to verify the microbiological and physicochemical quality of yoghurts marketed in the city of Rio Pomba, MG. Samples from seven brands were analyzed. For total and fecal coliforms, the samples presented below 2 CFU/g. In relation to analysis of lactic acid bacteria, only in one sample was found value greater than 107 CFU/g, according to current legislation. The marks range between 14.12% to 18.52% for ESD, of those five were above the limit recommended by current legislation (15% ESD). All samples heeded the standard set by the legislation for acidity (0.6 to 1.5g of lactic acid/100g). For proteins, four of them were out of limits established by law (minimum 2.9g/100g). Also, four samples presented starch in its composition. In relation to the count of filamentous fungi and yeasts, the samples are in accordance with the current legislation. Thus, a more efficient surveillance is necessary, given that part of the brands analyzed did not meet the standards set by legislation.
