This study was undertaken to determine the microbiological flora of 66 raw material samples and 24 of mixed feed samples. Thirty-three raw material samples were taken from different farms just after harvesting and 33 from different factories before processing. Of mixed feed samples 12 were collected from factories and 12 from stores. The raw materials taken from storage contained higher moisture levels than raw materials taken from factories. Moisture levels were higher in corn than other raw material. Parallel to moisture levels, the total bacteria and mold counts were higher in raw material samples taken from storage, ranging from 5.43 to 6.40 and 3.51 to 4.60 (log10/g) per gram of diet with mean value of 5.913 (log10/g) and 4.055 (log10/g) respectively Total aerobic bacteria and mold counts were higher in corn than in other raw material. The bacterial and fungal counts and moisture levels in mixed feeds were significantly higher (P<0.05) in samples taken from stores. Results obtained in this study indicated that temperature, moisture levels and duration of storage are critical factors which affect the microbiological quality of fish feeds.
