Isolation of Enteric Bacteria from Various Sources in Selected Poultry Farms in Kaduna State
This study was designed to isolate enteric bacteria from various sources in selected poultry farms in Kaduna state. One hundred and fifty samples of poultry feed, water and droppings from five poultry farms in Kafanchan, Zaria, Gonin-gora, Kamazou and Ungwan Television were examined for the presence of enteric bacteria. 30 samples were collected from each farm and were analysed using spread plate method. The culture media used were Selenite Feaces (SF) broth) and Bismuth sulphite agar. The
... hite agar. The contaminants isolated include Escherichia coli, Salmonella spp and Proteus mirabilis. The distribution of the isolates based on sample type were droppings (1.33%) and feed (2.67%). There was no significant difference in each of the samples (p>0.05). The percentage distribution of isolates based on location were: Kafanchan (0.00%), Zaria (0.00%), Kamazou (33.33%) for Salmonella and (16.67%) for Proteus mirabilis, Gonin-gora (50%), and Television (0.00%). The results showed that the poultry feeds and droppings from the poultry farms visited in Kaduna, Nigeria had bacteria contaminants. The presence of these bacteria may be a serious health concern as these organisms are involved in causing various diseases. Therefore, hygienic measures should be taken in processing and handling of the poultry products being sold to general public. The national and local health authorities should enforce the food hygiene regulations to reduce the spread of diseases caused by these enteric bacteria. Public enlightenment programmes on the modes of transmission of Salmonella, E. coli and P. mirabilis should be conducted by Human and Veterinary Public Health services. Further studies should be conducted to know the extent of distribution of these organisms in different areas of Kaduna State and the country at large.
