Microbiological quality assessment of raw milk and water samples from Noakhali district, Bangladesh
Keywords:water quality; milk contamination; total viable bacterial count (TVBC); total coliform count (TCC); yeast-mold count
This study was carried out to evaluate the microbial quality of raw milk and water samples taken at four different local shops in Maijdee area (Noakhali District), Bangladesh. Milk is a valuable food-stuff consumed on daily basis and is highly prone to bacterial contamination. Contamination with pathogenic microorganisms is most alarming for potable water and hence it is needed to detect the bacterial contamination in local drinking water. Microbiological quality of milk samples was analyzed using Total Viable Bacterial Count (TVBC), Total Coliform Count (TCC) and Yeast-mold Count techniques. Critical hygienic indicator for food and foodstuffs is total microbial load. Compare to four stores, store 3 shows the high contamination value in milk samples (TVC 12.48×105 cfu/ml, TCC 6.4×105 cfu/ml, yeast- mold count 3.48×102 cfu/ml and 4.85×102 cfu/ml) whereas store 1 is liable to water samples (TVC 12.09×105 cfu/ml, TCC 4.81×105 cfu/ml, yeast- mold count 2.7×102 cfu/ml and 2.24×102 cfu/ml). These outcomes accentuate applying and sustaining proper hygiene practice throughout the manufacturing and distribution to prevent health risks of the rural people.
