Microbiological Profile of the Traditionally Collected Industrial Raw Milk from the Milk Pocket Zones of Bangladesh

Abstract

The study was aimed to evaluate the bacteriological profile of the traditionally collected industrial raw milk from the milk pocket zones of Bangladesh. About 365 raw milk samples were collected from the milk tanker, who brought raw milk from the mother chilling centre where raw milk was chilled at 4°C following traditional method. All milk samples were subjected to perform standard plate count and total coliform count. The average standard plate count was found to be 4.37 x 10⁶ cfu/ml and the highest occurrence of standard plate count was found to be 6.70 x 10⁶ cfu/ml in October and the lowest (3.28 x 10⁶ cfu/ml) in March. The highest occurrence of total viable bacteria was found to be 5.64 x 10⁶ cfu/ml in autumn and the lowest was found to be 3.78 x 10⁶ cfu/ml in summer. On the other hand, the average of the coliform bacterial count was found to be 3.88 x 10⁵ cfu/ml with the highest (5.70 x 10⁵ cfu/ml) occurrence in May and the lowest (1.90 x 10⁵ cfu/ml) in January. Moreover, the highest occurrence of coliform count was found to be 4.84 x 10⁵ cfu/ml in rainy season and the lowest was 2.75 x 10⁵ cfu/ml found in winter.
