Sixty samples of raw cow milk were collected from four different locations in Madurai for their microbiological and chemical compositions analysis. The average levels of major chemical components were: fat (6.14%), crude protein (3.77%), lactose (4.25%), total solids (18.10%) and ash (0.80%). Microbiological enumeration revealed for the counts of total mesophilic aerobic bacteria, 5.84 log cfu/ml; bacterial endospores, 2.37 log cfu/ml; lactic acid bacteria, 4.46 log cfu/ml; coliforms, 2.76 log cfu/ml; Escherichia coli, 1.63 log cfu/ml and Staphylococcus aureus, 1.92 log cfu/ml. Listeria spp. were below detection level in all of the samples. The microbiological quality of raw cow milk was judged marginal and indicates the need for improved hygienic standards.
