This study aimed to establish a diagnostic about quality of raw milk in a farm of Rio Pomba, Minas Gerais and to apply good agricultural practices. Samples of production ambient including teats, liners and hands of milkers were collected and it was evaluated the contamination degree of total coliforms, fecal coliforms, Escherichia coli and coagulase positive Staphylococcus. Also, raw milk samples from each animal, raw milk sample from the expansion tank and samples of water used on the farm for sanitization were collected to evaluate the physico-chemical and microbiological quality. Besides, those responsible for milking process were t rained in good agricul tur al practices. It was verified after training, reduction up to two log cycles into microorganisms groups evaluated onto hands of milkers and teats. For individual milk, after training, it was verified that 51% of samples were in agreement with Brazil Standard. In relation to raw milk samples collected into expansion tank, it was found that before and after training all evaluated parameters was in agreement with established standards, with reduction of microbial count in one log cycle after adoption of good agricultural practices. Of the eight water samples evaluated, only one showed satisfactory results. Water of bad quality can compromi se milk quali ty. Application of good agricultural practices on the farm promoted the improvement of the physical-chemical and microbiological quality of individual raw milk and of bulk cooled raw milk.Downloads
