      Pasteurized cow’s milk stalls with the concept of street vendors become one of the culinary tourism destinations in Surakarta City. Sanitary and hygiene efforts are sometimes difficult to be handled for micro, small and medium enterprises (MSMEs) such as street vendors, and milk adulteration is likely to occur. This study aimed to evaluate the physico-chemical and microbiological quality of pasteurized cow’s milk sold at street milk stalls in Surakarta City. Samples were obtained from 30 milk stalls across five sub-districts in Surakarta City with 2 replicates. Parameters observed included physical properties (alcohol, pH, acidity, and density), chemical composition (moisture content, dry weight, fat, and protein) and microbiological quality (Total Plate Count and Enterobacteriaceae). Analysis of data was carried out using analysis of variance (ANOVA) unidirectional pattern, followed by Duncan’s new Multiple Range Test (DMRT) to evaluate differences in quality between shops. The results showed the mean of each physical parameter were alcohol negative; pH 6.67; acidity 0.12%; and density 1.0219 kg/l. The average chemical composition of pasteurized milk was : 91.83% moisture content; 1.88% fat; 6.30% lean dry weight; and 2.05% protein. Meanwhile, on microbiological parameters, the average TPC was 4.46 log CFU/ml and Enterobacteriaceae was 0.41 CFU/ml. The results showed that the pasteurized milk between the stalls showed a very significant difference (P<0.01) on all physico-chemical and microbiological parameters tested except the alcohol parameter (P>0.05). The conclusion of this study is that pasteurized milk sold by Surakarta street vendors is safe for consumption due to low microbiological values, but was not within the standard of nutritional requirements according to SNI and the best physico-chemical.
