Microbial Quality Of Cow`s Milk From Different Sources in Khartoum North Locality

Abstract

This study was carried out to evaluate microbial quality of raw cow`s milk taken at different sampling points from farmers, groceries and milk vendors in Khartoum North. The results were as follows frames total viable count of bacteria was 3.65±0.03 cfu/ml, yeasts and moulds 0.897±0.03 cfu/ml, staphylococcus aureus 1.18±0.26 cfu/ml, total coliforms 5.11±0.60MPN/mL, E. coli 1.11±0.19 MPN/ml, Salmonella was not detected in the modern farm while detected in traditional farm. Groceries total viable count of bacteria was 4.78±0.92 cfu/ml, yeasts and moulds0.94±0.63 cfu/ml, staphylococcus aureus 2.05±0.84 cfu/ml, coliforms 18.5±0.97 cfu/ml, E. coli 1.89±0.27 cfu/ml, Salmonella was not detected in the supermarkets while was detected in traditional shops and all vendor. Milk vendors total viable count of bacteria was 6.47±0.97 cfu/ml, yeasts and moulds 2.95±0.97 cfu/ml, staphylococcus aureus 3.40±0.73 cfu/ml, coliforms 49.1±13.4 MPN/mL, E. coli 15.00±3.41MPN/mL. These result revealed that the microbes less pollution compared groceries this may be due to the milk man or good practices for milking on the farm. The milk vendors are the most contaminated samples this may be due to the milking environment or pots and milk, as well as the movement of vehicle traveling salesman milk it makes it more susceptible to microbes that may comes from dust and frequent conquest of pots and milk and there for entry of microbes.
