The Occurrence and Antibiotics Sensitivity Profile of Salmonella and Escherichia coli in Commercial Poultry Feeds in Minna, Niger State
The study was conducted to determine the presence of Escherichia coli and Salmonella pathogens from different brand of commercially available poultry feeds in Minna metropolis. A total of 60 samples from three poultry feeds namely; Starter, finisher and layers were aseptically collected and analyzed using standard microbiological techniques. All samples analyzed were cultured on Nutrient agar media by spread plate’s technique and subsequently on selective media for total bacterial count. Total viable count (TVC) of Salmonella and E. coli recorded in the feeds were as follows: starter 3.47cfu/g, finisher 4.84 cfu/g and layers 9.02 cfu/g. There was a significant (p<0.05) trend in the overall percentage distribution of Salmonella and E. coli contamination across the feed’s category, with the higher distribution recorded in layers 100% and finisher while, starter had (66.6%) distribution. The overall result of antibiotics susceptibility tests of Salmonella and E. coli revealed the sensitivity of (53.8%), and resistant of (46.1%) in E. coli while, Salmonella had (38.4 %) sensitivity and (61.5%) resistant to all antibiotics tested. Thus, all the poultry feeds were found to be contaminated with bacteria which may pose a public health risk to human. Therefore, the occurrence of Salmonella and E. coli in poultry feeds reinforces the need for effective control measures, hygiene in processing and handling of feeds.
