Resumo: Despite the ban on the consumption of raw milk in Brazil, in many regions there is still the commercialization of this product. In the city of Lavras, MG state, the marketed is common in many establishments, and their quality is questionable because there is no control by the producers, much less by merchants. Thus, this study was conducted to evaluate the physico-chemical, fraud detection and standard of raw milk marketed and consumed in Lavras. We analyzed 10 samples of milk collected from different points of sale, being held three repetitions for each. In each were analyzed: acidity, density, fat content, total solids and non fat dry matter, research of hydrogen peroxide, starch, formaldehyde, chloride and sucrose, determining the volume, cryoscopic index, protein content, peroxidase and alkaline phosphatase. In the analysis of cryoscopic index, (20%) had mean values outside the standard. As for fat content, we observed that 10% were below the minimum acceptable for raw milk in full. For all samples, the average values of density were within the recommended limits. For non fat dry matter content, (20%) were below regulatory standards and (30%) had medium acidity out of the track. Regarding the presence of starch, hydrogen peroxide, chloride, sucrose and formaldehyde, all samples were negative. It is stressed then the risk of consumption of this type, because there is no legislation and continuously monitored, thus facilitating possible fraud with unhealthy foods and do not guarantee the integrity of milk, as observed in this work. The results were analyzed by descriptive statistics and compared to official standards established by the legislation.
