MICROBIOLOGICAL QUALITY OF GOAT MILK PRODUCED ON ALAGOAS STATE, BRAZIL

Abstract

The objective of this study was to verify the microbiological quality of raw and pasteurized goat milk and produced in Alagoas state, Brazil. Was carried out three interval collect of pasteurized and raw milk and the samples taken to the laboratory. All samples were subjected to aerobic mesophilic microorganisms counting, psychrotrophic microorganisms, determination of the most probable number (MPN) of total coliforms and thermotolerant microorganisms. For analysis, samples were plated on specific medium (Baird-Parker Agar Base himedia M043) and incubated at 37 °C for 24h. To Salmonella sp. detection was used plating the medium Salmonella Shigella agar. The presence of coliforms at 35 °C was detected in all samples as well as 45 °C except to first sample. To the pasteurized milk was found to coliforms at 35 °C and 45 °C in the second and third samples. Only in the second test was checked the presence of mesofilic bacteria. We have not found samples contaminated with microorganisms psychrotrophic, Salmonella sp. and Staphylococcus sp. According to the obtained results the quality of collected milk has unacceptable conditions of consumption compared to coliform counts, according to the parameters established by law.
