Was obtained a diagnostic by an interview and in situ evaluation of management conditions and milk samples for laboratory analysis integrating the platform and microbiological counts, before and after of GMSP. The changes achieved were no significant （P 〉 0.05） for pH and density, but alcohol and foreign material were positive modified （P 〈 0.05） by GMSP in both hand and machine milking. The quantities of sediments were decreased （P 〈 0.05） in more than 50.0%. Decrease （P 〈 0.05） was observed in the counts of CFU mL1 （colony forming unitsl） in aerobic mesophilic, coliforms, Salmonella ssp. and Staphylococcus aureus with the GMSP. After GMSP Salmonella ssp. incidence was affected （P 〈 0.05） by hand （55.5%） vs. machine （61.5%） milking type; coliforms count and positive incidence in milk were affected （P 〈 0.05） in hand （81.5%） vs. machine （53.9%）. Therefore it was confirmed that the implementation of adequate sanitary and management practices, in both hand and machine milking, decreased the presence and incidence of microorganisms in milk with potential to produce disease in animals and humans.展开更多
