| Abstract | ||||
| Three hundreds and twenty fish samples from Tilapia nilotica and Clarias lazera as fresh water fish and Pagrus sp. and Solea sp. as marine water fishes were collected from Ismailia fish markets as 20 sample from each species/season. Count, isolation and identification of Enterobacteriaceae organisms as well histamine level were determined in the examined samples by means of thin layer chromatographic methods. Lowest levels of histamine were recorded from Pagrus sp., Solea sp., Tilapia nilotica then Claroas lazera. Average counts of AEnterobacteriaceae organisms isolated from muscles of Pagrus sp., Solea sp., Tilapia nilotica then Claroas Jazera. caught during autumn, winter, spring and summer were <102, <102, 2x103, 4x103, <102<102 x102 5x102, 103 <103, <102, 5x103 104 2x102, 2x103 104 and 104 respectively. Higher counts of Enterobacteriaceae were recorded during summer due to higher temperatures. Public health importance of histamine and isolated organisms were discussed. | ||||
