    Bacteriological quality and heavy metals in edible meat portion of Japanese threadfin bream (Nemipterus japonicus)
    (2007) Prasad, M.M.; Imam Khasim, D.; Bandyopadhyay, J.K.; Gupta, S.S.
    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

    Microbial quality of post-tsunami seafood of the Visakhapatnam coast
    (Society of Fisheries Technologis(India), 2006) Rao, B.M.; Gupta, S.S.; Surendran, P.K.
    Forty seafood samples comprising marine fish (28 spp), shrimp (4 spp) and squid (Isp) were collected from Visakhapatnam fishing harbour at regular intervals after the tsunami of 26th December 2004 and analyzed for microbiological and chemical quality. The microbiological and chemical quality of post-tsunami seafood was assessed and compared with pre-tsunami samples. The levels of total plate count (TPC), H2S producing bacteria, total volatile base nitrogen (TVBN) and peroxide value (PV) was within limits. With regard to indicator bacteria eoliforms, E.coli and coagulase positive Staphylococci the quality of post-tsunami seafood was poor, having levels higher than the maximum permissible limit in majority of the samples. Similar trend was noted in the pre-tsunami and post-tsunami seafood quality. Human pathogens, Salmonella and Vibrio cholerae were not detected in all the post-tsunami seafood samples. The results suggest that no major deviation in the seafood quality occurred during the post-tsunami period
