Abstract

Nile fish genus (Oreochromis niloticus) production is graded on the highest of cultivation fish in Egypt. This study was aimed to screen microorganism related to cultivation fresh-water fish genus to see the microbiological safety of those wide distributed fish in Egypt. The mean viable microorganism count from fish fillets with the skin samples unconcealed five.6 ± 0.8 logs CFU/g. a complete of 11 (11) microorganism species were isolated and known including: E. coli, E. coli O157: H7, enterics enterica, Morganella morganii, Proteus genus Mirabilis, Proteus vulgaris, Enterobacter cloacae, Enterobacter cancerogenus, Hafnia alvei, Aeromonas hydrophila, Photobacterium damaselae. The frequency of incidences of the isolated microorganism indicated that Enterobacter cloacae had the very best frequency of occurrence (12%), whereas one isolate (2%) of enterics enterica, E coli O157:H7, and Aeromonas hydrophila were detected. These microorganism species are doubtless unhealthful to humans. Therefore, sanitary handling strategies and correct process are required before consumption of this fish.
