Abstract
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
