We analyzed 120 samples of milk samples and teatcupscollected in different periods from a dairy farm located in Auriflama, São Paulo State, Brazil. Microbiological analyses were carried out in accordance with the rules in force for determination of microorganisms in food and equipment. It was observed a high number of Staphylococcus aureus (76.6% of the samples). In 53.33% it was found coliform contamination by total coliforms, 35% by thermotolerantcoliforms and Escherichia coli . No samples presented Salmonella contamination. In the milk collected after cooling, in March, it was observed high mesophilic aerobic counts. Staphylococcus aureus and thermotolerants Coliforms were present in all samples analyzed. E. coli was isolated in samples of March and April. On the evaluation of swabs of teatcups , It was found E. coli and S. aureus . It is concluded and that the milk shall be collected from hygienic way, associated with mastitis control programs and hygiene equipment, mainly at the time of greatest rainfall,once the number of microorganisms increases and the refrigeration does not improve the quality of the product, it just keeps it. 2012 artículo científico 1900-9607 https://www.redalyc.org/articulo.oa?id=321428107002 pt http://www.redalyc.org/revista.oa?id=3214 Revista CES Medicina Veterinaria y Zootecnia application/pdf Universidad CES Revista CES Medicina Veterinaria y Zootecnia (Colombia) Num.1 Vol.7 |
