Estimation of Mercury Intake from Consumption of Fish and Seafood in Russia

Data on the mercury concentration in freshwater and marine fish and seafood on the territory of Russia are presented. The level and pattern of the fish and seafood consumption in various regions of Russia are found from the analysis of open statistics. Regions with the maximum and minimum consumption of fish products are established. Mercury intake from these products in a human organism is calculated. It is shown that at the current level and pattern of the diet in Russia fish cannot be a source of high mercury concentrations in a human organism.

At-Home Consumption of Fish Products in Malaysia: An Analysis of Household Expenditure Survey Data

ABSTRACT Expenditures on fresh fish, shellfish, and processed fish for home consumption are investigated for households in Malaysia. A sample selection system is estimated to account for observed zero expenditures and improve statistical efficiency of estimates. Results of marginal effects, segmented by ethnicity, indicate that household size and age of household head are associated with expenditures for all three fish products across ethnic groups. Location, urbanicity, and education are associated with expenditures on certain types of fish products among ethnic Malays and Chinese only. Policy recommendations include targeting larger households with lower prices for bulk purchases and consuming households in older age groups. Efforts to promote regularity of fish product purchases should be directed toward urban Malay and Chinese households seeking convenient cooking methods, while measures to boost fresh fish consumption could be concentrated among higher-educated Malay households, given their unexpecte...

Econometrics in the Fishing Industry Management

The mission of fishing companies is satisfying the social needs in such valuable and vital food as fish and fish products. The main goal of the companies is guaranteeing food security. For the effective management of fishing industry there should be the understanding and scientific assessment of the factors influencing the specified goals. In research by the means of the multiple regression equation it has been found that the level of fish and fish products consumption in Ukraine depends directly on their import. It is shown that the country is losing its potential in fishing industry as well as its ability to support food security. The necessity of extreme supporting measures is noted in the research within the scope of governmental policy regarding the fishing industry management.

Pyrosequencing as a Tool for Rapid Fish Species Identification and Commercial Fraud Detection

The increased consumption of fish products, as well as the occurrence of exotic fish species in the Mediterranean Sea and in the fish market, has increased the risk of commercial fraud. Furthermore, the great amount of processed seafood products has greatly limited the application of classic identification systems. DNA-based identification allows a clear and unambiguous detection of polymorphisms between species, permitting differentiation and identification of both commercial fraud and introduction of species with potential toxic effects on humans. In this study, a novel DNA-based approach for differentiation of fish species based on pyrosequencing technology has been developed. Raw and processed fish products were tested, and up to 25 species of fish belonging to Clupeiformes and Pleuronectiformes groups were uniquely and rapidly identified. The proper identification based on short and unique genetic sequence signatures demonstrates that this approach is promising and cost-effective for large-scale surveys.

Detection of antibiotics in feed and farmed fish

Background The consumption of fish products bring significant health benefits, therefore the demand for fish is greatly increased and this request is satisfied by farmed fish. Several studies have reported the presence of pharmacological residues as antibiotics in farmed fish with potential hazardous to the consumer. Use of Crystal Violet (CRI), Gentamicin (GE), Fluoroquinolones (FUQ), Chloramphenicol (CLO), Malachite Green (MG), Furaltadone (FU) and Furazolidone (FZ) is banned by Reg. CE 37/2010 for the severe effects on consumers. Aims The aim of our study was to evaluate the presence of antibiotics banned in the EU in fish muscle and in feed used for their feeding. Methods The sample extraction was carried out by specific ELISA Kits-BioScientific. Detection of antibiotics was carried out by use of a microplates reader Thermo scientific. Results All antibiotics tested were identified in feeds.The mean concentration of ?antibiotics, is 40.44 ppb. In feed prevails use of GE, CRI and CLO (respectively with average of 31.84; 4.05 and 3.67 ppb).The fish tissues showed a positivity to all drugs investigated with a mean concentration of CLO, CRI, VM, FU and FZ respectively of 0.57; 2.05; 0.45; 0.29 and 0.09 ppb. With a mean ? of 3.45ppb. Conclusion Our data showed that feeds used for fish feeding are contaminated by antibiotics banned and this contamination is detected in the muscle of farmed fish. In fact the 50% of farmed fish are used in the production of fish meal, primary component of the feed, hence occurs the bioaccumulation of drugs in the muscle of farmed fish.The consumption of farmed fish therefore may represent a risk to consumers that must be managed by strengthening of targeted checks for the fish- feed quality.

Consumption of Fish Products across the Lifespan and Prostate Cancer Risk

ObjectiveTo examine whether fish and fish oil consumption across the lifespan is associated with a lower risk of prostate cancer.DesignThe study was nested among 2268 men aged 67–96 years in the AGES-Reykjavik cohort study. In 2002 to 2006, dietary habits were assessed, for early life, midlife and later life using a validated food frequency questionnaire. Participants were followed for prostate cancer diagnosis and mortality through 2009 via linkage to nationwide cancer- and mortality registers. Adjusting for potential confounders, we used regression models to estimate odds ratios (ORs) and hazard ratios (HRs) for prostate cancer according to fish and fish oil consumption.ResultsAmong the 2268 men, we ascertained 214 prevalent and 133 incident prostate cancer cases, of which 63 had advanced disease. High fish consumption in early- and midlife was not associated with overall or advanced prostate cancer. High intake of salted or smoked fish was associated with a 2-fold increased risk of advanced prostate cancer both in early life (95% CI: 1.08, 3.62) and in later life (95% CI: 1.04, 5.00). Men consuming fish oil in later life had a lower risk of advanced prostate cancer [HR (95%CI): 0.43 (0.19, 0.95)], no association was found for early life or midlife consumption.ConclusionsSalted or smoked fish may increase risk of advanced prostate cancer, whereas fish oil consumption may be protective against progression of prostate cancer in elderly men. In a setting with very high fish consumption, no association was found between overall fish consumption in early or midlife and prostate cancer risk.

MARICULTURE DEVELOPMENT IN INDONESIA: Prospects and Constraints

Mariculture is an important component of Indonesian fisheries and aquaculture production, directly contributing an estimated US$ 320 million in 2008. Because most mariculture production is focussed on producing for export markets, mariculture production is an important source of foreign earnings for the Indonesian economy. This paper reviews the current status and prospects for continuing development of mariculture in Indonesia. Currently the major mariculture commodity in Indonesia is seaweed for carrageenan production. Seaweed production accounts for 98% of total Indonesian mariculture production and 84% of value. The other major commodity groups are marine finfish and pearl oysters. Commodities being developed for mariculture in Indonesia include abalone and spiny lobsters. Prospects for continued development of mariculture in Indonesia appear positive. Indonesia has several advantages for mariculture development, including many potential mariculture sites, a stable tropical climate, and does not suffer from cyclonic storms. The Government of Indonesia is planning to increase aquaculture production substantially over the next four years, including mariculture production. Globally, demand for seafood products is expanding due to increasing population and increased per capita consumption of fish products. Constraints to the continued development of mariculture in Indonesia include: limited seed supply, particularly of species which cannot be economically produced in hatcheries, such as spiny lobsters; need to develop more efficient production systems for some marine finfish; the need to improve environmental sustainability by improving feeds and reducing environmental impacts; and market issues relating to environmental sustainability.

Fish products available in Polish market – Assessment of the nutritive value and human exposure to dioxins and other contaminants

Chemical analyses were performed on one hundred and twenty of the most popular varieties of fish products (smoked fish, salted fish, and marinated fish) of the fish market in Poland. The contents of the nutritive substances of fish products (protein, micro- and macronutrients, vitamins A 1, D 3, E, and fatty acids) and the chosen contaminant (toxic metals – mercury, cadmium, lead, arsenic; dioxin/furans – PCDDFs; dioxin-like PCB – dl-PCBs; seven congeners of polybrominated diphenyl ethers – PBDEs; organochlorine pesticides – ΣDDT, HCB, ΣHCH and marker polychlorinated biphenyls – PCB 7) levels were determined. It was confirmed that fish products are a good source of digestible proteins, iodine, selenium, and vitamin D 3. The fundamental nutritive benefit of processed fish lies in its highly beneficial fatty acid composition, which is what imparts them healthy nutritive qualities. The high content of long-chain polyunsaturated fatty acids (LC-PUFAs), which is not noted in other food products, is particularly important. The majority of contaminants studied were present in low levels. The possible threats, particularly in the case of pregnant/nursing women and young children, can pose the levels of dioxin/furans (PCDD/Fs) and dioxin-like (dl-PCBs) in smoked Baltic salmon and smoked sprat, elevated in a relation to particular requirements concerning the content of sum of PCDD/Fs and dl-PCBs in fish (8 pg WHO-TEQ g −1). The health benefits and risks stemming from consumption of fish products were determined according to the Provisional Tolerable Weekly Intake (PTWI) for chosen contaminants (Cd, Hg, As, PCDD/Fs + dl-PCB) and the quantity of ingredients that render a fish diet healthy based on data from the EFSA Journal [EFSA (European Food Safety Authority), 2005. Opinion of the scientific panel on contaminants in the food chain on a request from the European Parliament related to the safety assessment of wild and farmed fish. EFSA J. 236, 1–118]. In regard of high content of LC-PUFAa and other nutritive ingredients, fish products available in Polish market may be considered as healthy food. However, many authors point at contaminants (methylmercury, PCDD/Fs) occurring in fish and fish products as on potential health problem, and emphasize that the amount of that hazardous substances should be limited in human diet.

Anisakid larva in the viscera of a farmed Atlantic salmon ( Salmo salar)

Parasitic nematodes of the family Anisakidae occur in the visceral cavity and surrounding tissues of many marine fish species at a prevalence as high as 100% in wild salmon samples. Human consumption of fish products containing these parasites can result in the zoonotic disease anisakiasis, and Anisakis simplex is most commonly associated with human disease. Previous studies of farmed salmon have found no anisakids in viscera or muscle, presumably because formulated feed production renders parasite larvae nonviable. However, among farmed Atlantic salmon ( Salmo salar) examined by histopathology as part of a provincial government auditing program in British Columbia, Canada, 1 of 894 (0.11%) had an anisakid larva partly embedded in the wall of an intestinal cecum. Skeletal muscle is not examined as part of the government's program, but other studies have correlated anisakids in the viscera and muscle. Using anisakid prevalence in viscera as an estimate of its prevalence in muscle, the risk ratio of anisakid parasites in commercial product is 570 times less in farmed than in wild Atlantic salmon.

Variability of fish consumption within the 10 European countries participating in the European Investigation into Cancer and Nutrition (EPIC) study.

To describe and compare the consumption of total fish (marine foods) and the fish sub-groups - white fish, fatty fish, very fatty fish, fish products and crustacea, in participants from the European Investigation into Cancer and Nutrition (EPIC) study. Cross-sectional analysis of dietary intake using a computerised standardised 24-hour recall interview. Crude means, means and standard errors adjusted by age, season and day of the week were calculated, stratified by centre and gender. Twenty-seven redefined centres in the 10 European countries participating in the EPIC study. In total, 35 955 subjects (13 031 men and 22 924 women), aged 35-74 years, selected from the main EPIC cohort. A six- to sevenfold variation in total fish consumption exists in women and men, between the lowest consumption in Germany and the highest in Spain. Overall, white fish represented 49% and 45% of the intake of total fish in women and men, respectively, with the greatest consumption in centres in Spain and Greece and the least in the German and Dutch centres. Consumption of fatty fish reflected that of total fish. However, the greatest intake of very fatty fish was in the coastal areas of northern Europe (Denmark, Sweden and Norway) and in Germany. Consumption of fish products was greater in northern than in southern Europe, with white fish products predominating in centres in France, Italy, Spain, The Netherlands and Norway. Intake of roe and roe products was low. The highest consumption of crustacea was found in the French, Spanish and Italian centres. The number of fish types consumed was greater in southern than in northern Europe. The greatest variability in consumption by day of the week was found in the countries with the lowest fish intake. Throughout Europe, substantial geographic variation exists in total fish intake, fish sub-groups and the number of types consumed. Day-to-day variability in consumption is also high.

Benign thyroid disease and dietary factors in thyroid cancer: a case-control study in Kuwait.

We conducted a population-based study of 313 case–control pairs in Kuwait to examine the aetiology of thyroid cancer, the second most common neoplasm among women in this and several other countries in the Gulf region. Among the demographic variables, individuals with 12+ years of education had a significantly reduced risk of thyroid cancer (OR=0.6; 95% CI: 0.3–0.9). The average age at diagnosis (±s.d.) of thyroid cancer was 34.7±11 years in women and 39±13.4 years in men. History of thyroid nodule was reported only by cases (n=34; 10.9%; lower 95% CI: 12.0); and goitre by 21 cases and four controls (OR=5.3; 95% CI: 1.8–15.3). There was no significant increase in risk with history of hypothyroidism (OR=1.8) or hyperthyroidism (OR=1.7). For any benign thyroid disease, the OR was 6.4 (95% CI: 3.4–12.0); and the population attributable risk was about 26% (95% CI: 21.1–30.9). Stepwise regression analysis showed that high consumption of processed fish products (OR=2.2; 95% CI: 1.6–3.0) fresh fish (OR=0.5; 95% CI: 0.4–0.7) and chicken (OR=1.7; 95% CI: 1.2–2.3) were independently associated with thyroid cancer with significant dose-response relationships. Among the thyroid cancer patients who reported high consumption of fish products, a large majority also reported high consumption of fresh fish (98%) and shellfish (68%). No clear association emerged with consumption of cruciferous vegetables. These data support the hypothesis that hyperplastic thyroid disease is strongly related to thyroid cancer; and that habitual high consumption of various seafoods may be relevant to the aetiology of thyroid cancer. The association with chicken consumption requires further study.British Journal of Cancer (2002) 86, 1745–1750. doi:10.1038/sj.bjc.6600303 www.bjcancer.com© 2002 Cancer Research UK

The uptake metabolism and biological half-life of benzo[ a]pyrene in different tissues of sea bass, Dicentrarchus labrax

The disposition of polycyclic aromatic hydrocarbons in aquatic organisms is of interest from the viewpoint of both animal and human health. The kinetics of uptake and metabolism of benzo[ a]pyrene (BaP) were studied in various tissues of the marine fish, sea bass, upon intraperitoneal injection of the compound. A decrease in radioactivity occurred in all tissues and the calculated half-lives were 12.4 days for fat, 6.5 for kidney, 5.1 for intestine, 4.8 for gallbladder, 4.5 for spleen, 2.9 for muscle, 2.4 for whole body, 2.3 for gonads, 2.3 for gills, and 2.2 for liver. The kinetics of distribution of radioactivity between alkali and hexane tissue extracts were determined in order to assess the overall metabolic potential of various organs. The liver, intestine, gills, and kidney displayed a relatively high metabolic potential in comparison with the spleen, muscle, gonads, and fat. The significance of the observations with respect to understanding mechanisms of toxicity is briefly discussed. Attention is specifically drawn to the presence of a fairly active metabolism or metabolite redistribution system in the muscle and the potential for exposure of blood cells to metabolites via hydrocarbon transformation processes in the spleen. This in vivo study, in which hydrocarbon disposition was studied in various tissues, also supports the hypothesis that polycyclic aromatic hydrocarbons should not bioaccumulate to any significant degree in fish and that exposure of humans to such compounds through the consumption of fish products can be expected to be minimal.

A review of the U.S.S.R. fishing industry

Abstract Since World War II the Soviet Union has increased the output of its fishing industry nearly tenfold. To achieve this the USSR had to shift operations from inland and coastal waters to the open seas. The process of converting the fishing industry from being based primarily on inland waters and on individual fishermen to operating in coastal waters and organizing state-planned and controlled enterprises was started before WWII. The postwar period saw the Soviet Union reach further and further into the oceans of the world. She rapidly increased her fleet capacity by construction at home and in other communist countries. Investments in the fishing industry increased from 1 4 of one per cent of the total investments in the country in pre-war years to 1% during the 1966–70 Five Year Plan. As a result, the size of individual units increased. The Soviet fleet acquired large modern processing mother ships, operating far away from home bases, and trawlers equipped with processing and freezing facilities. An increasingly higher proportion of the catch was caught and processed far from home. the fastest growth occurred during the sixties. In 1961 31.7% of all vessels had refrigeration facilities, in 1970 63.2%. The catch per vessel increased from 248 MT in 1960 to 681 MT in 1970; on fishing and processing refrigeration vessels it had reached 11,350 MT. The newly built fleet units have encountered difficulties in finding depleting resources of fish. In 1959 to catch 1 MT of fish in the open seas the average distance covered by the fleet was 1655 miles, by 1966 the distance had increased to 2881 miles. The increase in the size of the fishing fleet and of its processing capacities had led to an increase in the consumption of fish products in the USSR from 6.7 kg in 1913 to 18.5 kg in 1976. Furthermore, during the decade 1966–1975 alone, the Soviet Union exported about 1.5 billion dollars worth of fishing industry products. The rapid growth of the world output of sea products has brought about a change in the attitude of various nations to sea resources. One after another, coastal states have declared 200-mile economic zones, placing countries with large fishing fleets in a difficult situation. The Soviet Union is one of the countries most effected by the new restrictions. She will have to re-deploy her fishing fleet, partly into her own coastal waters and partly to foreign economic zones on the basis of new agreements or joint ventures. In spite of the difficulties faced, the Soviet Union plans to increase the output of her fishing industry during the current Five Year Plan (1976–1980) by 0.785 million MT. However, this increase is to be considerably less than during the previous Five Year Plan, when it amounted to 2.529 million MT.
