Abstract

This study was conducted to investigate contamination of drinking water in selected dairy farms in Sudan based on bacterial isolation and total viable count. A total of 50 farms were examined. The farms were from five areas in Khartoum State namely Shambat, Alsamrab, Alhalfaia, Helat Koko and Helat Kogaly. Ten farms from each area were examined. A total of 50 drinking water samples (one from each farm) were collected. All water samples were examined for bacterial viable count and cultured to isolate common bacteria present. Sixty three bacterial isolates were recovered from all samples. The isolated bacterial genera were Bacillus, Corynebacterium, Enterobacteria, Staphylococcus, Streptococcus, Actinobacillus, Campylobacter, Moraxella, Aeromonas, Cardiobacteria, Pseudomonas and Branhamella. All water samples examined showed moderately high viable count. The mean viable count from the 10 farms in each area was 12X107, 37X106, 22X106, 22X106 , 20X106 (cell/ ml) for Shambat, Helat Kogaly, Alsamrab, Alhalfaia and Helat Koko areas respectively. Most of the examined farms were with bad hygiene specially surround drinking water troughs. It could be concluded that drinking water quality in selected dairy farms was poor.
