Abstract

The goal of the present study was to verify the quality of refrigerated raw milk from dairy properties and also of refrigerated raw milk, pasteurized and Ultra High Temperature (UHT) milk from industries in Vale do Taquari in Rio Grande do Sul, Brazil. Physicochemical, microbiological and milk composition analysis were carried out, as established by legislation, in addition to total and thermotolerant coliforms and psychrotrophic counts in the three types of milk and mesophiles count in pasteurized milk and UHT milk from the industries. The collections took place in two industries and 33 dairy properties. Regarding the properties, two (6%) had milk with acidity above that established by legislation and three (9%) had milk with a total bacterial count (TBC) above the established. The milk from industry 1 presented acidity, TBC and density out of the established standards. The two industries and 53.2% of the properties had milk with somatic cell counts (SCC) above that determined by legislation. The milk from the industries showed higher amounts of SCC, TBC, psychrotrophic and total and thermotolerant coliforms than the milk from the dairy properties, and the milk from industry 1 showed higher amounts than the industry 2, in the microbiological parameters.
