Milk is generally considered a complete diet with high nutritional value for all age groups. The present study focused on evaluating the fresh raw milk sold at outlets to determine its physicochemical composition, adulteration, and mycotoxin contamination. The dairy milk samples (n=20) collected from Nall, a nearby remote area of Khuzdar District, were analyzed using a Lacto-scan, Dairy Milk Adulterant Detection Kit, and Thin Layer Chromatography. The results regarding the physicochemical composition, including Total Fats, Solids-Not-Fat (SNF), Density, Sugar Contents (Lactose), Salt, Protein, Added Water, Freezing Point, Conductivity, and pH, showed a significant (P<0.05) difference among sales outlets. The overall mean percent values were 2.85±1.21, 6.31±1.72, 20.37±5.65, 3.43±0.96, 0.50±0.14, 2.32±0.62, 31.65±19.74, -0.39±0.12, 3.67±0.55, and 6.65±0.19, respectively. The results of the screening for adulterants revealed that the collected milk samples were found to be adulterated with detergent, sugar, and skim milk, with adulteration percentages of 10%, 30%, and 25%, respectively. However, adulteration with hydrogen peroxide, boric acid, starch, urea, carbonate, formalin, hypochlorite, sodium chloride, and pulverized soap was not observed. Aflatoxin M1 contamination above the permissible limits was evident in 5% of samples.
