Abstract Monitoring the bacteriological quality with respect to microbial loads, faecal pollution, human bacterial pathogens, red halophilic bacteria and fungi and toxicological monitoring studies for the presence of histamine, heavy metals, pesticides and carcinogens in fish, fishery products and fishery environments ofAndhra Pradesh was carried out. Faecal Streptococci were detected in more than 80% of the samples. E. coli (20-60%), coagulase positive Staphylococci (15-70%) and Non 01
Vibrio cholerae ( 15-25%) were detected in some of the amples. Bacterial isolates from cultured fish did not show development of antibiotic resistance towards medically important antibiotics. Treatment of cured and sun-dried fish with sodium tri-polyphosphate controlled the growth of red halophilic bacteria. Aspergillus flavus, Aspergillus niger, Pencillium sp., and Mucor sp. were the dominant fungi isolated from salted and dried fish samples collected from Visakhapatnam coast. Fresh marine fishes from local markets had 2.4 mg to 8.4 mg of histamine per 1 OOg muscle. There was no noticeable change in histamine formation in 24 hour iced fish. Fish from inshore waters of Visakhapatnam where the water is exposed to oil pollution showed presence of naphthalene, acenaphthalene, phenanthrene and anthracene compounds. The level of benzopyrene in smoked edible flesh portions of shrimp was much lower than in smoked whole shrimp. Accumulation of Pb, Cd, Cu and Zn in most fishes was in the order liver > intestines > skin > muscle. Total Hg in the meat of shrimp being exported was very negligible and within tolerable limit.
