Back ground and Objectives: Milk is a highly nutritious food that serves as an excellent growth medium for a wide range of microorganisms. Rapid, simple and inexpensive microbiological quality determination methods including Methylene Blue Reduction (MBRT) test could be commonly used as a quick method to assess the microbiological quality of raw and pasteurized milk. The aim of study is to determine quality of kids milk using Methylene Blue Dye Reduction Test Methods: A total of 37 samples comprising of kids milk collected at different levels of collection and processed. Accordingly 12 different milk samples from hypermarket, 8 different milk samples from unlicensed hawker (retail market), 11 different samples with additives from hyper market samples and 6 different samples with high price. Samples were collected. One ml of the Methylene Blue Thiocyanate solution added into a test tube then 10 ml of milk poured into test tube. Tubes incubated at 37 oC Results: Results showed that all types of milk that purchased from super market, local market and high price milk types shown no change of methylene Blue color appear on the base of time, that indicate very good quality of the milk. On the base of milk types with additive materials only one milk showed change in colour but after confirm test the colour remained blue and not changed. Conclusion: Methylene blue reduction test is rapid economic method that can be used for detection of milk quality. Approximately all the kids of milks that is purchased in our market and local markets showed sterility and the source contamination if take place may be by storage condition and transvers vehicle.
