Abstract:
This study was conducted through ( Nov.2016) to evaluate the quality of
fresh fish Orechromis sp, Bagrus sp, Claris sp at almawrada fish market
based on sensory and microbial testing , Sensory examination using the
European scheme in this scheme the fish were classified in to four categories
depending the firshness of fish excellent quality (E) , very good grade (A) ,
good grad (B) grad, undesirable grad (C).And Microbial taste for the total
bacterial count and isolated pathological bacteria (Escherichia coli
,Salmonella) .
165sample were collected from almawrada fish market ,55 sample from
each species , drawn from 10 ton and total of 30 swabs samples were
obtained 10 samples from each species for microbial and analysis.
the result found that there was highly significant difference in sensory
evaluation between fresh fish Orechromis sp, Bagrus sp, Clarias sp. As the
average skin of fishes at respectively (1.5±7 , 1.8±.9 , 2.9±.9) and outer
slime ( 1.5±.8 , 2.2±1, 2.9±1) and eyes ( 1.8±.8 , 2.3±.9 , 2.9±.9 ) and gill
color ( 1±.7 , 2±.7 , 3±.7) peritoneum (1.7±.1 , 2.1±.9 , 2.9±.9) and gill odour
(1.1±.7 , 2±1 , 2.9±.7) the Clarias sp is beast quality, and the total number of
bacterial load for fresh fish Orechromis sp, Bagrus sp, Clarias sp
respectively at ( 5.9 ×105±.18×105c.f.u./g , 4.05×105±.31×105c.f.u./g,
4×105±.47×105c.f.u./g). Result indicates no significant difference in toatal
bacterial count from the studied ssp.
The result indicates tha salmonella and E.coli were isolated as Pathogenic
bacteria.
Generally the handling, preservation and procsing of fish is un hygienic
and un safe. The poor condition in almawrada fish matket should draw
attention of the public authority consider all this deviation which no doubt
well affect the environment and human health.
