Abstract
One hundred and fitly samples of Japanese threadfin bream (Nemipterus japonicus) were screened for bacteriological
quality and for content of heavy metals. Out of 150 samples, 40.7% had the count above the stipulated limits for TVB
(5.7 log cfulg-) The samples harboured 28,7% of faecal conforms which were present in the range of 2-3 log cfu/g,
while 32 and 6% of the samples contained 3-4 and 5 lug cfu/g of the sample. Fecal Streptococci was present in 4N-.
at 2-3-log cfu/g and 29,3% at 3-4 log cfu/g. The samples contained coagulase positive Staphylococci, E, coil, Salmonella
and V cholera (Non 01) at 14.7, 44, 10 and 14%, respectively. The samples showed a significant decreasein TVB
(3-4 log cfu/g of the sample), faecal coliforms and faecal Streptococci during 2 months storage at -18±1°C. Pathogenic
bacteria were also not present alter the 2 months storage. The samples were free from hazardous levels of heavy metals.,
like Cd, Cu, Hg and Pb
