This study evaluated the incidence of enteriobacteriacea from poultry feeds. Four different feed types (starter, grower, finisher and layers feed) were ed from feed brands (Vital feed, Top feed and Crown feed). The predominant bacteria isolated were Bacillus sp, Staphylococcus aureus, Serratia sp, Escherichia coil, Samonella sp, Kiebsiella sp and Shigella sp. .The viable counts of the feed samples ranged from 2.6 x105to 5.6 x107. The total heterotrophic plate count for the various feed samples ranged from 2.9 x105to 8.3 x106. The total coliform plate count for the various feed samples range from 3.1 x107to 5.6 x107. The total salmonella and shigella plate count for the various feed samples ranged from 2.6 x105to 4.7 x106. Escherichia coli was the most frequently occurring isolate with the percentage occurrence of (23.5%), this was followed by Shigeila sp with a percentage occurrence of (17.6%), then Klebsiella sp and Staphylococcus aureus with the percentage occurrence of (15.7%), Bacillus sp and Salmonella sp with a percentage occurrence of (11.8%), whereas Serratia sp has the least percentage occurrence of (3.9%). The bacterial load of the samples tested indicated that feed samples from Crown feed were mostly loaded with bacteria 20 representing (3 9.2%), followed by samples from top feeds 17 representing (33.3%) and the least loaded were those from vital feed 14 representing (27.5%). The antibiotic sensitivity test reviewed that Ciprofloxacin (88.2% is the drug of choice following to the fact that it show high rate of sensitivity to the bacterial isolates tested, this is followed by 'Gentamicin (80.4%), Levofloxacin (74.5%), whereas the bacterial isolates showed high rate of resistance Ampiclox with the percentage resistance of (76.5%), followed by Chioramphenicol (66.7%), then Amoxil (62.7%) and moderately resistant to Streptomycin and Rifampicin (56.9%). From the result of this study, it is necessary to evaluate a feed safety by bacteriological examination of poultry feed to ensure safety and quality of feed to prevent poultry diseases and great economic losses.
