Determination of The Microbial Quality of Hawked Pasteurized Cow Milk and Packaged Yogurt Products Sold in The Commercial Area of Federal Polytechnic Damaturu

Abstract

Bacterial load of selected hawked pasteurized cow milk and packaged Yoghurt products sold at the
commercial area of Federal Polytechnic Damaturu were determined. Three samples each of pasteurized
cow milk and packaged Yoghurt were randomly purchased from the commercial area and were put into
sterile plastic containers and transferred to the laboratory for analysis. The samples were analyzed using
prepared Nutrient agar media. Colonies formed were counted using colony counter and Gram staining
was conducted. The result revealed higher bacterial colony count in the cow milk samples. Sample 2A
is having 72x104Cfu/ml and the least colony count is obtained from sample 9 having 24x103cfu/ml,
respectively. Gram staining revealed majority of the samples are Gram negative. This indicates that
must hawkers of pasteurized cow milk are ignorant of the importance of personal hygiene and
sanitation. Therefore, it is recommended that the pasteurized cow milk hawkers be sensitize and
educated on the importance of personal hygiene and sanitation.
