The results showed that the incidence of salmonella in the examined samples of minced beef, meat block, breast meat ,thigh meat ,flesh of T.niloticus and flesh of M.cephalus were 35%, 25%, 20%, 30%, 15%and10% respectively.While serotyping of Salmonellae isolated from the examined samples were S.Enteritidis,S.Typhimurum and S.Virchow in block meat While in minced meat,they were S.Enteritidis,S.Typhimurum , S.Virchow and S.Heidberg inaddition to in chicken meat samples ,they were S.Enteritidis,S.Typhimurum , S.Virchow and S.Kentucky in breast meat and S.Enteritidis,S.Typhimurum and S.Kentucky in thigh meat . Salmonella strains isolated from mugil cephalus were S.Enteritidis,S.Typhimurum from T.niloticus were S.Enteritidis, S.Virchow and S.Infantis.Also enterotoxin gene were isolated from S.Enteritidis,S.Typhimurum,S.Kentucky and S.Virchow also could isolate hilA gene from S.Enteritidis,S.Typhimurum,S.Kentucky , S.Virchow and S.Heidelberg. FimH were isolated from S.Enteritidis, S.Typhimurum,S.Kentucky , S.Virchow ,S.infantis and S.Heidelberg.
