CALIDAD BACTERIOL ´ OGICA DE LECHE CRUDA DE CABRA PRODUCIDA EN MIRAVALLES, PUEBLA BACTERIOLOGICAL QUALITY GOAT RAW MILK PRODUCED IN MIRAVALLES,

In this study we determined the presence of Mesophilic Aerobic Bacteria (MAB), Total Coliform Bacteria (TCB) Fecal Coliform Bacteria (FCB) and the pathogen Salmonella. All of them were used as microbiological indicators to evaluate the best management practices and sanitation during the production process of raw goat’s milk. Milk samples were collected aseptically, each week, from cattle ranches in Miravalles Oriental, Puebla. Ten out of fifty five farmers were randomly selected. They used two types of management; grazing and feedlot. The data collected were analyzed by Analysis of Variance, the Nonparametric test of Kruskal-Wallis and Cluster Analysis. All samples of raw goat milk met the standards 92/46/EEC and NMX-F-COFOCALEC2007, with respect to the MAB. However, 50% of milk samples exceeded the microbiological limits established for TCB and FCB (NOM-243-SSA1-2010). These results were for milk samples from goats with feedlot management. In contrast, all samples successfully met these standards when collected from cattle herds that were grazed as did smaller heads. Finally, Salmonella was not detected in any sample of the raw milk.
