COMPARATIVE ASSESSMENT OF MILK BORNE PATHOGENS AND THEIR ANTIBACTERIAL SENSITIVITY
AbstractMilk is considered as a highly nutritious and valuable human food, consumed by the people in a variety of different products. The present work is an effort to have a survey of number of bacteria present in different milk samples viz., Raw, Boiled, Pasteurized and Skimmed milk collected from local market of Haridwar and its adjoining areas by serial dilution method and the quality of milk assessed by MBRT. The highest mean count was detected in raw milk having 211±0.8 cfu/ml. Among the four types, boiled milk appeared as of best quality. The major microbial contaminants were found to be Bacillus sp, Staphylococcus sp, Streptococcus sp, E. coli and Micrococcus sp. During the present investigation the antibiotic sensitivity test was also performed against all the five genera isolated. It was found that inhibition zone of Chloramphenicol and Ofloxacin was maximum against Streptococcus sp. (24 mm) and Staphylococcus sp. (30mm).
