Abstract

The study was conducted aiming at the isolation and identification of Salmonella and Escherichia coli (E. coli) from different brands of poultry feeds sold in Savar, Dhaka, Bangladesh. Seven different poultry feeds were subjected to microbiological analysis. All these samples were analyzed by culturing in different media such as nutrient broth (NB), nutrient Agar (NA), SS Agar (Salmonella-Shigella Agar), BGA (brilliant-green Agar), Mac Conkey, DHL and EMB (eosin methylene blue) media. Total bacterial colonies of all the samples were counted separately on the nutrient Agar media. Hence, bacteria were counted as 9.5×105 in the feed sample C (Layer) which was found to be the highest in number among the poultry feeds. Total viable count (TVC) of Salmonella and E. coli in the feed samples were as 0 to 6.75×104 and 0 to 3.05×104 respectively.  Both organisms were found in 71.43% and 57.14% of the analyzed feed samples, respectively. The highest number of Salmonella was found in sample C (Layer) feeds and that of E. coli was found in sample B (Grower) feeds. The widespread occurrence of Salmonella and E. coli in poultry feeds reinforces the need for effective control measures, hygiene in processing and handling of feeds.
