This work had as main objectives to characterize two bacteriocins produced by lactic acid bacteria (LAB) previously isolated from non-fermented seafood, in order to evaluate their potential as new food protective agents. The two bacteriocinogenic isolates were identified by Polymerase Chain Reaction (PCR) using genusand species-specific primers, and confirmed by 16S rDNA sequencing, as Enterococcus faecium and Pediococcus pentosaceus. The antimicrobial spectrum of each strain included several indicator microorganisms, some of them also isolated from seafood. Growth of Listeria innocua, L. monocytogenes, Staphylococcus aureus, Bacillus cereus and other LAB species were inhibited, although no inhibition of Gram-negative microorganisms was observed. Proteolytic, but not lipolytic or glycolytic enzymes, completely inactivated the antimicrobial effect of both cell-free supernatants confirming the proteinaceous nature of the inhibitors. The antimicrobial activity was maintained after treatment with NaCl, SDS, Triton X-100, Tween 20, Tween 80 and EDTA after 2 h or 5 h of exposure and both bacteriocins were stable over a wide range of pH and temperatures. Production of bacteriocin by E. faecium (bacALP7)was detected initially at exponential phase and reached a maximum activity of 25...

Dissertação para obtenção do Grau de Mestre em Tecnologia e Segurança Alimentar; The population from countries surrounded by the Gulf and Arabian Sea depend on fisheries. Industry is growing and discharges by desalination plants and refineries lead to the presence of heavy metals which accumulate in the environment and seafood. The aim is to review seafood contamination with cadmium, arsenic, lead and mercury in Saudi Arabia, Oman, Kuwait, United Arab Emirates, Bahrain and Qatar and estimate the consumer exposure to these metals. All samples of molluscs and crustaceans tested for arsenic (As) showed concentrations above maximum permitted levels, Qatar and UAE being the most contaminated. All samples from Kuwait contained lead (Pb), cadmium (Cd) and mercury (Hg). Bahrain samples contained Pb above permitted levels. On the coast of Oman and Qatar shellfish showed concentrations of Cd above permitted levels. The EWI for As from shellfish is above the PTWI for all samples. For Cd, all except shellfish from Oman, Bahrain and KSA entail a EWI above the PTWI. None of the samples, except from Kuwait, provide Pb above the PTWI and for Hg, only the clam, mussel and crab contain higher amounts. Four locations in the UAE contained fish with Cd above permitted levels. Tuna fish from KSA had higher levels of Cd and Pb. Highest levels of Hg could be found in fish from Kuwait. Bahrain and Qatar showed the highest levels of As. Hg EWI exceeded for the UAE...

Functional food presents specific physiological properties, supplies nutrients and can be naturally found in formulated food or added to it. Seafood plays an important role in human diet, representing the largest stock available of w-3 polyunsaturated fatty acids, especially eicosapentaenoic (EPA) and docosahexaenoic (DHA). Scientific researchers have intensified their studies on fatty acids due to their importance in preventing and/or curing diseases, especially cardiovascular and inflammatory ones. This review describes the most important aspects of w-3 fatty acids found in fish, as well as their roles in the mechanism involved in the prevention and control of diseases.

In recent years, increasing attention has been focused on the safety of foods, and in particular on the intervention methods to reduce and eliminate human pathogens from fresh product, especially fresh seafood. Traditional technology utilizes water with or without a sanitizing agent to wash fresh seafood. Chlorine is the most widely used sanitizing agent available for fresh product, but it has a limited effect in killing bacteria on seafood surfaces. An alternative treatment is being sought to improve food safety. Many research and industrial trials are underway to validate the use of ozone in the food industry. This article intends to show a clean technology to be applied in seafood industry and to show that many studies must be done to demonstrate the best concentrations and the best methods of ozone applications in diverse seafood species, so that the governments of all the countries can approve their application in the fishing industry.

An on-line method for Cd and Pb pre-concentration and simultaneous determination in acid digested seafood by inductively coupled plasma optical emission spectrometry (ICP OES) was developed. The on-line pre-concentration was based on the complex formation of the analytes with the ammonium salt of O,O-diethyldithiophosphate (DDTP) and using the Amberlite XAD-4 resin as a solid support in a homemade column. Different conditions of the flow injection system, such as solutions flow rates, nebulizer pressure and eluent concentration were optimized. Three certified reference materials of lobster hepatopancreas, dogfish liver and fish protein, three samples of fish muscle and three samples of shrimp were digested with HNO3, H2O2 and H2SO4 in a microwave system under reflux. DDTP was added in the solutions obtained, and the mixture was injected in the FI system. Calibration curves for Cd and Pb were obtained using the standard solutions in the concentration range 0.05-0.5 µg mL-1 in the digestion medium, submitted to the same pre-concentration procedure. The quantification limits (3.3 x LOD) for 5 min of pre-concentration time were 0.005 mg kg-1 Cd2+ and 0.1 mg kg-1 Pb2+ in the sample of fish or shrimp in natura, considering 1.0 g of the sample in a final volume of 50 mL. The agreement of the obtained concentrations with the certified ones (Student t-test...

The present study was conducted to determine the virulence and cytotoxicity of Aeromonas hydrophila strains isolated from seafood samples collected from 5 major fish markets in Chennai, Tamil Nadu, India. Among 73 A. hydrophila strains isolated from fish and shrimp samples, 86.3% exhibited haemolysis, 78.1% produced slime, 98.63% produced protease and also demonstrated cytotoxicity on Vero cells. Cell shrinkage, detachment and rounding of Vero cells were recorded as cytotoxic changes. Only one strain did not show haemolysis, slime production, proteolytic activity and cytotoxicity on treatment with Vero cells. Positive correlation was observed between proteolytic activity and cytotoxicity irrespective of haemolytic activity of the strains. These results demonstrated the presence of wide spread, pathogenically characterized, cytotoxic seafood borne A. hydrophila in Chennai.

Background: Fish and seafood provide important nutrients but may also contain toxic contaminants, such as methylmercury. Advisories against pollutants may therefore conflict with dietary recommendations. In resolving this conundrum, most epidemiologic studies provide little guidance because they address either nutrient benefits or mercury toxicity, not both. Objectives: Impact on the same health outcomes by two exposures originating from the same food source provides a classical example of confounding. To explore the extent of this bias, we applied structural equation modeling to data from a prospective study of developmental methylmercury neurotoxicity in the Faroe Islands. Results: Adjustment for the benefits conferred by maternal fish intake during pregnancy resulted in an increased effect of the prenatal methylmercury exposure, as compared with the unadjusted results. The dietary questionnaire response is likely to be an imprecise proxy for the transfer of seafood nutrients to the fetus, and this imprecision may bias the confounder-adjusted mercury effect estimate. We explored the magnitude of this bias in sensitivity analysis assuming a range of error variances. At realistic imprecision levels, mercury-associated deficits increased by up to 2-fold when compared with the unadjusted effects. Conclusions: These results suggest that uncontrolled confounding from a beneficial parameter...

Part I of this article introduces the American seafood and shellfish industry and provides some background data on the composition of the market as well as consumption patterns in the United States. Consideration is given not only to the domestic commercial supply, but also to a significant import segment of the market as well as recreational fishing and harvesting. Part II addresses the various risks to seafood and shellfish consumers. Again, though risks across the entire industry are addressed, particular attention is given to those risks specific to the shellfish industry. The risks discussed range from those inherent to different types of seafood to health hazards of purely human origin. Both the level of threat and the seriousness of these different health hazards are presented and analyzed. Current means of risk identification and reduction are examined briefly throughout this section. Part III begins a more specific examination of past attempts at health and safety regulation of the shellfish industry. This portion of the article provides the historical context of current shellfish safety programs while documenting the development and ultimate demise of previous attempts at industry regulation. The section begins with the creation of the National Shellfish Sanitation Program (NSSP) in 1925 and continues through its merger into the International Shellfish Sanitation Conference in 1998. Along the way...

Demand for high levels of quality and safety in fish production obviously require high standards in quality assurance of raw materials and process control. Satisfying this demand in turn requires appropriate analytical tools for analysis both during and after production. Desirable features of such tools include speed, ease of use, minimal or no sample preparation, and the avoidance of sample destruction. These features are characteristic of a range of spectroscopic methods including mid-infrared (MIR) and near-infrared (NIR) spectroscopy. This article reviews some of the recent technical applications of infrared (IR) spectroscopy to determine and monitor composition and other quality characteristics in raw fish, fish products, and seafood.; Daniel Cozzolino and Ian Murray

Cyanobacteria (blue-green algae) are abundant in fresh, brackish and marine waters worldwide. When toxins produced by cyanobacteria are present in the aquatic environment, seafood harvested from these waters may present a health hazard to consumers. Toxicity hazards from seafood have been internationally recognised when the source is from marine algae (dinoflagellates and diatoms), but to date few risk assessments for cyanobacterial toxins in seafood have been presented. This paper estimates risk from seafood contaminated by cyanobacterial toxins, and provides guidelines for safe human consumption.; Vanora Mulvenna, Katie Dale, Brian Priestly, Utz Mueller, Andrew Humpage, Glen Shaw, Graeme Allinson and Ian Falconer

BACKGROUND: Several agencies recommend seafood to be consumed 2-3 times per week. In Australia, there is a lack of nutrient composition data for seafood species and it is not known whether including different seafood species in a diet would provide sufficient long-chain omega 3 fatty acids (LC n-3 PUFA) to meet various national recommendations. OBJECTIVE: To utilise recent nutrient composition data for major Australian seafood groups (n=24) with the addition of two tuna options (total n=26) to: (1) determine whether including these species into a diet based on the Australian Guide to Healthy Eating (AGHE) will achieve LC n-3 PUFA recommendations [Adequate Intake (AI: 160 mg/d men, 90 mg/d women)], Suggested Dietary Target (SDT), 500 mg/d Heart Foundation (HF) recommendation and (2) determine the weekly number of servings of seafood to meet recommendations using either lower fat (n=23, <10% total fat) or higher fat (n=3, ≥10% total fat) seafood. DESIGN: Two simulation models incorporated all 26 species of seafood or only lower fat seafood into a diet based on the AGHE. Two further models identified the number of servings of lower or higher fat seafood required to meet recommendations. RESULTS: Including 2 and 3 servings/week of any seafood would enable 89% of women and 66% of men to meet the AI. Including only lower fat seafood would enable 83% of women and 47% of men to meet the AI. Half a serving/week of higher fat seafood would enable 100% of men and women to meet the AI. CONCLUSIONS: Including the recommended 2-3 servings of seafood/week requires at least some higher fat seafood to be consumed in order for most men and women to meet the AI. Further messages and nutrition resources are needed which provide options on how to increase intake of LC n-3 PUFA...

Food lipid major components are usually analyzed by individual methodologies using diverse extractive procedures for each class. A simple and fast extractive procedure was devised for the sequential analysis of vitamin E, cholesterol, fatty acids, and total fat estimation in seafood, reducing analyses time and organic solvent consumption. Several liquid/liquid-based extractive methodologies using chlorinated and non-chlorinated organic solvents were tested. The extract obtained is used for vitamin E quantification (normal-phase HPLC with fluorescence detection), total cholesterol (normal-phase HPLC with UV detection), fatty acid profile, and total fat estimation (GC-FID), all accomplished in <40 min. The final methodology presents an adequate linearity range and sensitivity for tocopherol and cholesterol, with intra- and inter-day precisions (RSD) from 3 to 11 % for all the components. The developed methodology was applied to diverse seafood samples with positive outcomes, making it a very attractive technique for routine analyses in standard equipped laboratories in the food quality control field.

Fish production has increased in Brazil, mainly the fresh-water aquaculture. However, refrigerated fish presents a relatively short shelf-life (approximately 12 days). In view of the increasing demand for fresh products, there is the need of shelf-life lengthening through a combination of methods in order to minimally expose the product to adverse conditions. The use of the modified atmosphere packaging presents the following advantages: lengthening of the products' shelf-life by 50 to 400%, reduction of economic losses, cost reductions by distributing the product over great distances with the need of fewer shipments and the supply of a better quality product. The purpose of this work was to review and discuss the major effects of the modified-atmosphere packaging, especially carbon dioxide (CO2), on seafood preservation, as well as on the survival and growth of seafood pathogenic organisms.

A precise, simple and rapid method is described for the determination of inorganic arsenic [As(iii)+As(v)] in seafood products. The inorganic species were isolated from the matrix by microwave-assisted distillation and determined by hydride generation atomic absorption spectrometry (HGAAS). The microwave and chemical parameters were optimized in order to obtain quantitative inorganic arsenic recoveries. The analytical features of the method are as follows: detection limit 10 ng g(-1) (dry mass) or 2 ng g(-1) (fresh mass); precision (RSD) 4%; recoveries 106 +/- 3% for As(iii) and 113 +/- 4% for As(v). Under the optimized conditions, arsenobetaine, arsenocholine and tetramethylarsonium ion added to samples of seafood were not distilled; however, minor species were distilled and were detected in various percentages: 109% monomethylarsonic acid; 11% dimethylarsinic acid; 0.2% trimethylarsine oxide. The concentrations expressed as arsenic contributed by these species would imply a mean overestimate of inorganic arsenic of about 24 ng g(-1) dry mass (dm). The concentrations of inorganic arsenic found in natural seafood samples ranged between 0.053 and 1.145 mu g g(-1) (dm) (mean moisture content 78%). The procedure was compared with an alternative methodology in which acid digestion-solvent extraction-HGAAS was used for the determination of inorganic arsenic. A Student's t-test for paired samples of the data obtained by the two methodologies showed no significant differences (P -value 0.66).; Comisio´n Interministerial de Cienc´ıa y Tecnolog´ıa (CICyT)...

A method for the selective quantitative determination of inorganic arsenic [As(III) + As(v)] in seafood was developed. In order to do so, various procedures for the solubilization and extraction of inorganic arsenic quoted in the literature were tested. None provided satisfactory recoveries for As(III) and As(v) in real samples. Consequently, a methodology was developed which included solubilization with HCl and subsequent extraction with chloroform. The arsenic was solubilized in 9 mol 1(-1) hydrochloric acid. After reduction by hydrobromic acid and hydrazine sulfate, the inorganic arsenic was extracted into chloroform, back-extracted into 1 mol 1(-1) HCl, dry-ashed, and quantified by hydride generation-atomic absorption spectrometry (HG-AAS). The analytical features of the method are as follows: detection limit, 3.07 ng g(-1) As (fresh mass); precision (RSD), 4.0%; recovery, As(III) 99%, As(v) 96%. In the optimized conditions, other arsenic species-dimethylarsinic acid (DMA), arsenobetaine (AB), arsenocholine (AC) and tetramethylarsonium-ion (TMA(+))-were not co-extracted. However, different percentages of minor species were extracted with chloroform: monomethylarsonic acid (MMA) 100%, and trimethylarsine oxide (TMAO) 3-10%. Real samples and reference materials of seafood (DORM-1...

Fish products have become the most traded food commodities worldwide but wild fish stocks face ever-increasing pressure from rising demand (Smith et al., 2010). Over 75% of the world’s fisheries are currently either fully or over exploited (FAO, 2014). Developing sustainable fisheries is critical if seafood is to remain available for future generations. Global Value Chain (GVC) analysis frames these challenges holistically by linking global and local scales in order to elucidate operations and relationships throughout the international supply chain. In this study we employ the GVC framework to analyze the production of mahi mahi (Coryphaena hippurus) from Ecuador and Peru that is exported to the United States. Information was collected from stakeholder interviews and analyzed in conjunction with trade and production data. This information was then used to construct product flow patterns, characterize governance structures, and provide insights for potential economic and environmental improvements. The importance of mahi mahi as an export commodity to small-scale fishers in developing countries combined with its highly migratory life history typify many of the challenges facing modern global fisheries. Peru and Ecuador together produce the highest volumes of mahi mahi globally. Nearly 60% of all mahi mahi imported into the United States comes from these two countries. In this analysis...

Cotugna, Nancy; Background: Seafood is an excellent source of essential omega-3 polyunsaturated fatty acids (PUFA) in the diet. The 2005 Dietary Guidelines for Americans (DGA) advocate the intake of two servings of fish per week noting a link with potential cardiovascular health benefits. Many health organizations, including American Heart Association and the American Dietetic Association, concur with this recommendation. Objective: The purpose of this study was to advance our understanding of consumer perceptions and reasons for current decisions regarding seafood consumption. It is important to identify differences in characteristics of those who eat the recommended amount of seafood and those who do not, in order to promote seafood consumption to the population as a whole to meet the national recommendations. Design: This secondary data analysis of a nationwide Internet survey compared current seafood eaters who consume the DGA recommended amounts (CSE-R) with those not meeting recommendations (CSE-NR), former seafood eaters (FSE) and non-seafood eaters (NSE), to further clarify the knowledge, attitudes and perceptions of consumers with regard to seafood. Statistical analyses included cross tabulations of consumption groups with demographic variables and individual items found in questions on attitude...

This article examines the historical trends of Tokyo’s marine seafood consumption and tensions over how to promote urban sustainable consumption. Despite overwhelming evidence that global fish stocks are depleting, the Tokyo Metropolitan Government has not advanced an agenda to directly support sustainable seafood consumption. In this vacuum national government policies, increasing wealth, changes in preferences and private initiatives have promoted the consumption of ever larger amounts of seafood. Notwithstanding these forces, however, consumption patterns since the 1970s have changed in unpredictable ways. The per capita proportion consumed of prized, high trophic level and high status seafood, such as carnivorous fish, is declining while the consumption of other types of seafood from lower trophic levels is increasing. Moreover, seafood prices seem to play little role in these trends. Despite their great wealth and the forces that are promoting increased consumption, those living in Tokyo cannot overcome the biophysical limits posed by increasing depleted marine stocks. These results suggest an urgent need to begin implementing policies that will help lower seafood consumption at the local...
