The milk samples (Raw and Boiled) were collected from various vendors of Hoshiarpur and Ludhiana district. Three different samples of Pasteurized milk samples were taken from the market. These samples were evaluated for their quality by determining Standard Plate Count (SPC) and Coliform count. The bacterial colonies ranged from 0.7×104 cfu/ml to 6×106 cfu/ml in boiled milk. Methylene Blue reduction test (MBRT) had also been performed to check microbial quality of the samples and Sample 1 (both raw and boiled) was reported to be poor.

The study was undertaken with an objective to evaluate a rapid PCR based method for detection of adulteration of buffalo milk in cow milk at minimum level of detection. This method utilizes primers targeting the mitochondrial encoded 12S rRNA gene as the target for species identification. PCR assay involve use of three different primers. Reverse primers specific for cow and buffalo complementary to the gene fragment of 12S rRNA along with the common forward primer. The cow specific primer, along with the common forward primer, yields a cow specific amplicon of 346 bp in the 12S rRNA gene.
