Abstract: Four brands of commercial poultry feeds (Vital, Top, Pfizer and Guinea) were subjected to microbiological analysis. Each of the four brands had four feed types namely Starters, Growers, layers and finishers feed. All these samples were analyzed by plating unto nutrient, Mc conkey and Potato Dextrose agars. Bacteria isolated from the samples are Staphylocuccus aureus, Bacillus subtilis, Pseudomonas aeroginosa, Proteus vulgaris, Erwinia sp., Enterobacter aerogenes, Micrococcus sp. and Escherichia coil while the fungal isolate were Penicillium sp., Rhizopus, Aspergillus and Cladosporium sp. The bacterial load of the feeds was in the range 1.13�108-3.0�107 with the Top Feed giving the highest number of bacterial contamination. Guinea, Vital and Pfizer feeds had the lowest number of contamination. The feeds were found to be contaminated and could pose potential health problems to the birds and humans.
