Normative instruction nº 62 brought new standards to be followed by producers, proceeding to continue the improvement of milk quality in progress since Normative instruction nº 51. However quality improvement of milk did not occur as fast as expected. The aim of this work was to evaluate the impact of good practices on milk quality in 49 dairy farms located in Ivaiporã/PR, through collective lectures and training courses. A reduction of 88,05% in Total Bacterial Count (TBC) in 28 (57,15%) dairy farms that implemented the good practices was observed. From those farms, 23 (47,93%) presented TBC bellow maximum of 750.000 CFU/mL as required by legislation at the period of analysis, with average counts of 166.826,1 CFU/mL. As for Somatic Cell Counts (SCC), 83,57% of all farms began to produce milk according with the standard set to this item at the time of analysis. Significant variations were not observed in physico-chemical parameters of milk after practices implementation. Implementation of the proposed practices was sufficient to produce milk according with standards established by legislation.
