Abstract
A polluted marine environment may end in food chain and pose risk to public health. Fish and fishery products are at the forefront of food safety and quality improvement because they are among the most traded food commodities. The present study was designed to screen the seafood samples for the levels of sanitary and safety indicators, to study the presence of bacterial sea food pathogens of zoonotic importance by conventional and molecular methods and their antibiotic resistance pattern by phenotypic methods, to estimate the level of heavy metal concentrations from the sea food samples and to assess the compliance with food hygiene requirements by comparing with the prescribed standards by ICMSF and FSSAI.
Assorted sea food samples which includes fishes, prawns, crabs and squids were collected from three major landing centers of Chennai, Royapuram Pattinapakkam and Ennore. A total number of 433 samples were collected which include 138 prawns, 145 fishes, 90 crabs and 60 squids, and a total number of 190 seafood samples from Royapuram, 153 from Pattinapakkam and 90 from Ennore landing centres.
The levels of sanitary indicators viz. aerobic plate count, yeast and mould count and coagulase positive Staphylococcus aureus count were studied.The Aerobic plate count from the landing centres ranged from 1.0x106 to 5x107CFU per gram. The maximum range of aerobic plate count was observed in crabs (1.0 x106 to 5.0x107 CFU per gram) from Royapuram. The Yeast and mould from all the three landing centres ranged from 1.0x101 to 5x103 CFU per gram. The maximum levels reported in crabs (1.0 x 101 to 5.0 x103 CFU per gram) from Royapuram. The number of coagulase positive Staphylococcus aureus ranged between 1x101 to 1x102 CFU per gram. Highest count (1x102 CFU per gram) observed in fishes from Royapuram. The sanitary indicators observed in all the three landing centres were in the prescribed limits of FSSAI and ICMSF, except for crabs and squids. A very high Significance observed for the interaction between sanitary indicators and seafoods (P<0.001). Significant difference (<0.05) observed for the interaction between sampling site and seafood.
