Resumo: | Current milk production includes a large diversity between systems, which generates difficulties in defining a microbiological standard. The adapted practical and hygienic-sanitary management methods are diverse and introduce great complexity into the production systems. Based on this scenario, the objective of this study was to evaluate the types of dairy production systems of western Parana and to quantify Staphylococcus sp in three critical points in the dairy cattle production systems: the milking machines, milkers’ hands, the cooling tanks and raw milk. A total of 35 samples of refrigerated raw milk were collected, and a questionnaire referring to hygienic and sanitary management was administered. All of the data were collected during the period from September to October 2012 and involved 35 properties in the municipality of Marechal Cândido Rondon – PR. From these data, five groups were formed based on cluster analysis (CHA). The multiple correspondence analysis (MCA) presented in the first two dimensions, CP1 (81.43%) and CP2 (36.87%), showed the relevance of the variables used, which are sanitary and production management methods, and contamination and control of mastitis, respectively (CP1 and CP2). We found average contamination with 9.9 x 101 CFU/cm2, 2.2x104 CFU/cm2, 28 CFU/ cm2 and 3.8x103 CFU/mL; for milking machines, milkers’ hands, cooling tanks and milk, respectively. The results reveal the presence of staphylococcal agent in dairy production systems regardless of the adopted hygiene and health management protocols. The guidance, planning and adaptation of hygiene and health management systems can significantly improve the microbiological quality of the milk produced, both qualitatively and quantitatively. |

A produção leiteira atual possui diversidade em seus sistemas existentes, ao gerar e proporcionar dificuldades em um padrão principalmente microbiológico. As práticas e manejos higiênico-sanitários adotadas são diversas e acarretam grande complexidade na evolução e melhora dos sistemas de produção. Com base nestes problemas, o objetivo do trabalho foi avaliar os tipos de sistemas de produção leiteiros da microrregião oeste do Paraná e quantificar Staphylococcus sp. em três pontos críticos na produção: ordenhadeira, mão-do-ordenhador, tanque de resfriamento e leite. Foram coletas 35 amostras de leite cru refrigerado conjuntamente com um guia semiestruturado referente ao manejo higiênico-sanitário existente, no período de setembro-outubro de 2012 no município de Marechal Cândido Rondon – PR. A partir destes dados (35 Sistemas de Produção Leiteiros), foram formados 5 grupos, conforme técnica de análise de clusters (CHA). A análise de correspondências múltiplas (ACM), apresentou nas duas primeiras dimensões, CP1 (81,43%) e CP2 (36,87%), importância para a explicação das variáveis utilizadas, sendo estas de produção e manejos higiênicos; e contaminações e controle de mastite, na devida ordem (CP1 e CP2). Foram encontradas contaminações médias de 9,9x101 UFC/ cm2, 2,2x104 UFC/ mão, 28 UFC/cm2 e 3,8x103 UFC/mL; para ordenhadeira, mãos dos ordenhadores, tanque de resfriamento e leite respectivamente. Os resultados encontrados revelam a presença do agente estafilococos nos sistemas de produção leiteiros, independentemente dos manejos higiênico-sanitários adotados. A orientação, planejamento e adequação dos manejos higiênico-sanitários podem melhorar significativamente a qualidade microbiológica do leite produzido, tanto qualitativamente quanto quantitativamente.
