Detection of Bacterial Contamination of Some Traditional Frozen Fish in Some Local Markets in Tikrit City

Abstract

Abstract This study was aimed to investigate bacterial contamination in frozen fish form samples collected from some local markets in several neighborhoods of Tikrit city. Thirty samples of frozen fish were collected for two types of fish common carp and fish fillet, laboratory bacterial isolation and diagnosis showed Staph. aurues samples constitute highest proportion of isolations which followed by Aeromonaus hydrophyla, E.coli, Psudomonas. Spp and Salmonella ( 7,6, 5 and 3) isolations. Bacterial number of isolations has been calculated where it showed a variant in number of bacterial colonies, Staph. aurues which recorded the highest rate in colonies number. Chemical analyses to estimate the amount of protein and fat showed 9.43, 7.31% of protein and 3.9, 8.66 % fat, so as to moisture was high in both carp and elephant fish 80.5, 75.72% and ash 2.31, 7% in carp and fish fillet, respectively. The results of current study shows there are an inverse relationship between both used fish in study and the moisture in the fish.
