Abstract:

ABSTRACT To evaluate the role of seafoods in the epidemiology of human listeriosis and the role of the processing environment as a source ofListeria monocytogenes in seafood products, 305 L. monocytogenes isolates were characterized by multilocus enzyme electrophoresis using 21 genetic loci and restriction enzyme analysis of total DNA. Forty-four isolates were recovered from patients in Norway; 93 were isolated from seafoods, seafood-processing environments, and seawater from 55 different producers; and the remaining 168 isolates originated from six seafood-processing plants and one transport terminal examined in detail for L. monocytogenes. The patient isolates fell into 11 electrophoretic types, with four of them being responsible for 77% of the listeriosis cases in 1992 to 1996. Isolates from Norwegian seafoods and processing environments showed great genetic diversity, indicating that seafoods and seafood-processing environments do not offer a niche for specificL. monocytogenes strains. On the other hand, isolates from individual processing plants were genetically more homogenous, showing that plants are likely to be colonized with specific subclones ofL. monocytogenes. The isolation of identical subclones ofL. monocytogenes from both human patients and seafoods, including ready-to-eat products, suggests that such products may have been possible sources for listeriosis cases in Norway.

Abstract:

The present study investigates the supply chain for seafood industries in Korea. Unlike previous studies, which analyze the supply chain from input users’ perspective only, the present study examines the supply chain from both input users’ (backward linkage) and input suppliers’ (forward linkage) perspectives. In doing so, this study utilizes structural path analyses (SPAs) to scrutinize the specific paths along which the effects of a shock to a seafood industry are transmitted in both backward and forward directions. This study executes these two types of SPAs (backward linkage and forward linkage SPAs) for three seafood industries in Korea that include wild fisheries, aquaculture, and seafood processing, thus depicting a more detailed and complete picture of the mechanisms through which the influences of the seafood industries spill over to the rest of the economy. One important finding is that our SPAs are able to identify a number of seemingly unlikely non-seafood industries that play a critical role in transmitting the effects of a shock to a seafood industry.

Abstract:

We use contingent behavior analysis to study the effects of pfiesteria-related fish kills on the demand for seafood in the Mid-Atlantic region. We estimate a set of demand difference models based on individual responses to questions about seafood consumption in the presence of fish kills and with different amounts of information provided about health risks. We use a random-effects Tobit model to control for correlation across each observation and to account for censoring. We find that (i) pfiesteria-related fish kills have a significant negative effect on the demand for seafood even though the fish kills pose no known threat to consumers through seafood consumption, (ii) seafood consumers are not responsive to expert risk information designed to reassure them that seafood is safe in the presence of a fish kill, and (iii) a mandatory seafood inspection program largely eliminates the welfare loss incurred due to misinformation.

Abstract:

This paper addresses the need to establish a fast, effective and reliable method for collecting fish and seafood consumption data at the village level. Two different approaches, a community participatory and a classical survey one were tested and validated against each other. Using fully structured questionnaire surveys also reliability of results obtained from household and individual interviews were compared. Furthermore, taking fresh fish consumption as an example, three different methods were assessed to approximate best per capita consumption. Approaches and methods are validated in terms of time and human resource requirements, and data quality by comparing data sets obtained in Polynesian and Melanesian communities. Adding efficiency criteria, adoption of household average consumption surveys is concluded to best combine reliable data and least time and financial requirements. Per capita fresh fish consumption was found to best estimated using a simplified WHO system that takes into account gender-age correction factors.

Abstract:

This study seeks to identify interproduct relationships between domestic catfish and a representative selection of imported seafood. In doing so, this study uses multivariate cointegration and structural analyses. Multivariate cointegration analysis suggests that six imported seafood product groupings form a common market with domestic catfish. Structural analysis reveals that 1) domestic and imported catfish are net and gross quantity substitutes; 2) domestic catfish and imported seafood are normal goods; 3) six imported seafood products are identified as gross quantity substitutes for domestic catfish; and 4) according to the derived Allais coefficients, interaction intensities of imported seafood for domestic catfish (from greatest to least) are as follows: tuna, shrimp, salmon, tilapia, catfish, and trout.

Abstract:

Background: Seafood is an important source of omega-3 fatty acids, which have been associated with improved oocyte quality and embryo morphology in some studies. However, seafood is also a source of persistent organic pollutants and heavy metals, which may adversely affect fecundity. Previous studies of seafood intake and fecundity have generated inconsistent results. Methods: In two prospective cohort studies of 7836 female pregnancy planners from Denmark (Snart Foraeldre, n = 2709) and North America (PRESTO, n = 5127), we evaluated the association of dietary intake of total seafood and marine-sourced long-chain omega-3 fatty acids (eicosapentaenoic acid, docosahexaenoic acid, and docosapentaenoic acid) with fecundability. Participants completed a baseline questionnaire on sociodemographics, behavioral factors, anthropometrics, and medical history, and a food frequency questionnaire. Pregnancy status was updated bimonthly for up to 12 months or until reported conception. We estimated fecundability ratios (FRs) and 95% confidence intervals (CIs) using proportional probabilities regression models, adjusted for energy intake and other potential confounders. We restricted analyses to women with ≤6 menstrual cycles of attempt time at enrollment. Results: Intake of total seafood or marine-sourced long-chain omega-3 fatty acids was not appreciably associated with fecundability in either cohort (≥200 vs. <50 g/week total seafood: FR = 0.94, 95% CI: 0.79–1.10 in Snart Foraeldre; FR = 1.00, 95% CI: 0.90–1.13 in PRESTO; marine fatty acids: ≥90th vs. <25th percentile: FR = 1.00, 95% CI: 0.85–1.18 in Snart Foraeldre; FR = 0.97, 95% CI: 0.86–1.09 in PRESTO). In PRESTO, where we collected additional data on seafood preparation, we observed an inverse association between fecundability and fried shellfish (≥10 g/week vs. none: FR = 0.77, 95% CI: 0.61–0.98), but not unfried shellfish (≥20 g/week vs. none: FR = 0.98, 95% CI: 0.89–1.07); in Snart Foraeldre, there was no association with total shellfish intake. Conclusions: We found little association between seafood intake and fecundability overall, but greater intake of fried shellfish was associated with reduced fecundability among North American participants.

Abstract:

Seafood provides n-3 long-chain PUFA (n-3 LC-PUFA), vitamins and minerals, which are essential to maintain good health. Moreover, seafood is a source of contaminants such as methylmercury, arsenic and persistent organic pollutants that may affect health. The aim of the present study was to determine in what quantities seafood consumption would provide nutritional benefits, while minimising the risks linked to food contaminants. Seafood was grouped into clusters using a hierarchical cluster analysis. Those nutrients and contaminants were selected for which it is known that seafood is a major source. The risk–benefit analysis consisted in using an optimisation model with constraints to calculate optimum seafood cluster consumption levels. The goal was to optimise nutrient intakes as well as to limit contaminant exposure with the condition being to attain recommended nutritional intakes without exceeding tolerable upper intakes for contaminants and nutrients, while taking into account background intakes. An optimum consumption level was calculated for adults that minimises inorganic arsenic exposure and increases vitamin D intake in the general population. This consumption level guarantees that the consumer reaches the recommended intake for n-3 LC-PUFA, Se and I, while remaining below the tolerable upper intakes for methylmercury, Cd, dioxins, polychlorobiphenyls, Zn, Ca and Cu. This consumption level, which is approximately 200 g/week of certain fatty fish species and approximately 50 g/week of lean fish, molluscs and crustaceans, has to be considered in order to determine food consumption recommendations in a public health perspective.

Abstract:

AbstractAttributes for two value-added seafood products derived from underutilized crawfish are analyzed using conjoint data from seafood restaurants in the southern region of the United States. Preferences for the products' form, price, and flavor attributes were tested. Statistical tests revealed that the attribute interactions were not significant, and part-worth utilities for all main effects were estimated using an additive preference model. Results indicate that the new crawfish products should be marketed as a high-quality fresh soup base or seafood stuffing, priced between 30% and 50% of the cost of fresh crawfish tail meat.

Abstract:

This study aims to determine the attributes that affect the level of customer satisfaction and the value of the level of customer satisfaction in the Bandar Djakarta restaurant of Alam Sutera of Tangerang City. The method used in this study is the method of importance-performance analysis to determine the attributes that affect customer satisfaction and the customer satisfaction index to determine the value of overall customer satisfaction. After all the data has been processed, the data will be analyzed descriptively. The technique used to take samples in this study is accidental sampling. Sampling was carried out for four weeks in July 2019 with a total of 85 respondents. The results of this study indicate that the attributes that make consumers feel satisfied are the variety of food, product taste, food hygiene, safety guarantees, the hospitality of the waitress, queuing time, room comfort and room cleanliness. While the attributes that make consumers feel less satisfied are the cleanliness of eating utensils and the speed at which food is served. The overall value of customer satisfaction is at 85,00.

Abstract:

Illegal, unreported, and unregulated (IUU) fishing is a serious global environmental crime. It can lead to the collapse of important fisheries and the destruction of marine habitats, and it also directly threatens the food security and economies of developing countries, affecting millions of people who depend on fisheries for survival. IUU fishing also undermines the sustainability of seafood stocks of many developed countries and directly impacts these countries’ legal commercial fishing industries. Several regulatory mechanisms have been put in place at international, regional, and country levels to address the problem, but the implementation of these regulations remains a challenge. This article examines the problem of IUU fishing and seafood fraud through the application of the crime script analysis technique to (1) describe IUU fishing and seafood fraud, (2) highlight the regulations designed to address IUU fishing and seafood fraud, and (3) offer recommendations that link piecemeal and grand crime prevention policy responses to strategies that could be used by practitioners to address these problems more effectively.

Abstract:

The United States is entering into a new era in which dwindling natural fisheries resources are forcing regulatory agencies to develop a more holistic approach to seafood safety and natural marine resource issues. Public health issues associated with seafoods can be grouped as (i) environmentally induced (i.e., natural or anthropogenic), (ii) process-induced, (iii) distribution-induced, or (iv) consumer-induced hazards. Similarly, loss of habitat and ecosystem degradation threaten the future viability of fisheries and have important ramifications for seafood safety. In the United States, large-scale legistlative efforts are underway to reexamine regulatory food control systems. The driving forces behind these efforts are the discovery of new emerging pathogens for which little information is available and dramatic improvements in analytic technology that allow for detection of low levels of microbial and chemical contaminants in foods. The global nature of seafood trading issues and the worldwide implementation of new preventative food safety programs such as hazard analysis for critical control points are driving some of the efforts to build new scientific bridges that will reevaluate current risk analysis strategies. New scientific bridges are needed to close the gaps between the scientific community and society concerning the effects of anthropogenic impacts on seafood safety and the heatlh of coastal habitats and associated fishery resources. The driving force behind this latter issue is the realization that the United States has lost over half of its original coastal wetlands areas. Protecting, conserving, and restoring the health and safety of our fisheries resources will require an integrated approach of food science and fishery science.

Abstract:

The article presents the results of the study conducted by the authors of the real trade assortment in the category "non-fish seafood". The purpose of this study was to conduct a research of the categorical assortment of non-fish seafood, determine its indicators, and analyze the assortment policy of three retail stores. The conducted research of the assortment of the category of non-fish seafood allowed revealing the real trade assortment in the examined stores. It is established that the category assortment of the Pyaterochka store is the closest to the rational one. The assortment policy of this store is characterized by the two main directions: the main one is stabilization, and the additional one is renewal. The Verny store has the highest stability coefficient, which indicates the main direction of the assortment policy — stabilization. It was found out that the basic depth of the category assortment for non-fish seafood reaches 38 brands and their modifi cations, and all stores present an assortment that is not repeated in the other examined stores.

Abstract:

Purpose The purpose of this paper is to explore consumer knowledge of seafood sustainability and how that knowledge influences the purchase of seafood products. Design/methodology/approach Using an online survey (n=1,319), the authors investigated Australian consumer knowledge of seafood sustainability and the drivers of purchase choice. Objective knowledge categories were developed through the qualitative analysis of unprompted, open-ended responses and compared with other surveyed measures of objective knowledge. The relationship between these knowledge categories and the importance of sustainability in the purchase decision was tested. Findings A significant group of consumers either had no knowledge of seafood sustainability (17.8 per cent) or gave an incorrect response (15.5 per cent), while 25.1 per cent demonstrated simple and 41.6 per cent complex knowledge. Further, the knowledge was positively related to importance of sustainability when making purchase decisions. Sustainability moved from the lowest ranked attribute for the no knowledge group to the highest ranked attribute for the complex knowledge group. Research limitations/implications The results show that the consumer knowledge about sustainable seafood cannot be assumed and that the level of sustainability knowledge influences the importance of sustainability in the purchase decision. Practical implications The results suggest that information-based strategies based on a universally shared definition of sustainability in the seafood industry designed to drive sustainable consumer behaviour for seafood must take the account of consumer knowledge. Originality/value This paper identifies and provides a classification framework for levels of consumer knowledge about sustainable seafood and demonstrates a positive relationship between knowledge and the importance of sustainability in consumer decisions with regard to purchasing seafood.

Abstract:

A prophage is a phage-related sequence that is integrated into a bacterial chromosome. Prophages play an important role in bacterial evolution, survival, and persistence. To understand the impact of Listeria prophages on their host genome organizations, this work sequenced two L. monocytogenes strains (134LM and 036LM), previously identified as lysogens by mitomycin C induction. Draft genomes were generated with assembly sizes of 2,953,877 bp and 3,000,399 bp. One intact prophage (39,532 bp) was inserted into the comK gene of the 134LM genome. Two intact prophages (48,684 bp and 39,488 bp) were inserted in tRNA-Lys and elongation-factor genes of the 036LM genome. The findings confirmed the presence of three corresponding induced phages previously obtained by mitomycin C induction. Comparative genomic analysis of three prophages obtained in the newly sequenced lysogens with 61 prophages found in L. monocytogenes genomes, available in public databases, identified six major clusters using whole genome-based phylogenetic analysis. The results of the comparative genomic analysis of the prophage sequences provides knowledge about the diversity of Listeria prophages and their distribution among Listeria genomes in diverse environments, including different sources or geographical regions. In addition, the prophage sequences and their insertion sites contribute to the genomic diversity of L. monocytogenes genomes. These data of prophage sequences, prophage insertion sites, and prophage sequence comparisons, together with ANIb confirmation, could be useful for L. monocytogenes classification by prophages. One potential development could be refinement of prophage typing tools for monitoring or surveillance of L. monocytogenes contamination and transmission.

Abstract:

This study is aimed at investigating the global trend in research activities involving seafood and antibiotics based on published research output articles. Peer reviewed articles published in the last two decades involving seafood and antibiotics were searched on the Scopus database using the search words “seafood” and “antibiotics’’. The retrieved data were then analyzed based on the total research outputs, countries and affiliation of authors, sources of funding, keywords used by the authors, citations and collaborations using both add-on analytical tool, Microsoft Excel and VOS viewer for data visualization. A total of 447 research outputs by 710 authors affiliated with 1173 institutions from 74 countries using 1051 keywords were obtained. Original research articles accounted for the highest percentage (87.7%) and published across 166 different peer-reviewed journals. Most of the original research articles were published in the International Journal of Food Microbiology 27(16.3%). Khan, A. A. from the Division of Microbiology; National Centre for Toxicological Research, United States, was the most productive author with 10 (2.2%) publications while the National Natural Science Foundation of China was the highest funding institution with 22 (4.9%) and the United States of America was the most productive with 91 (20.4%) research outputs followed by China with 70 (15.7%) research outputs. Over the last two decades (1999 – 2019), there has been an exponential (r2=0.91) increase in seafood and antibiotics related research activities. The majority of these research activities were from America, Asia and Europe. There is need for international scientific collaboration between the leading researchers and researchers from developing countries in seafood research to help mitigate food loss, enhance food security, and increase the productivity of early career researchers.

Full text

Abstract:

It is not suggested that any country is intentionally exporting seafood which does not comply with Codex seafood-safety guidelines/codes/standards. However, with an open access resource such as fisheries, there is vast potential for errors to occur along convoluted supply chains, spanning multiple countries, which may negatively impact the safety of edible seafood products imported into Australia. Australian importation policy and inspection procedures are founded upon a bedrock of trust in the integrity, reliability and safety of the global seafood supply chain. In order for seafood imported to Australia to be considered safe the non-mandatory international health standards, governed by Codex Alimentarius, for seafood must be predicated upon the most efficacious methods and stringently governed by each exporting provenance. Currently, tests for zoonotic parasites are not applied to imported edible seafood products on arrival into Australia. Therefore, this critical analysis is aimed at discussing the effectiveness of current testing protocols for zoonotic parasites in edible seafood advised by Codex Alimentarius which may impact the safety of the product imported into Australia.

This paper identifies factors that influence consumers' seafood safety perceptions and examines how these perceptions affect consumers' anticipated consumption when consumers are provided with additional information relevant to seafood. A recursive system of equations is specified describing consumers' safety perceptions as a function of past experience with seafood, recreational harvest activities, and risk-taking behavior, and describing the influence of safety perceptions on consumers' anticipated demand response to hypothetical information concerning seafood. A telephone survey of randomly selected Rhode Island consumers provided data for the analysis.

Abstract:

ABSTRACT With the expansion of e-commerce, an increasing number of Chinese consumers are turning to online markets to purchase foreign seafood. When buying seafood online, customers cannot physically evaluate the product, and the market Web page instead of the seafood label conveys all of the product information. However, specific regulations concerning the information presented on the Web page have not been created, which may foster seafood fraud and misdescription. Because mislabeling of seafood has become a widely reported issue in the Chinese offline market, the online scenario must be investigated comprehensively. This study focused on various seafood products that originated from 20 countries and were sold by one of the largest e-commerce companies in China. For each country, only the product with the greatest overall monthly transaction volume was selected, and 5 samples were purchased per product for a total of 100 samples. The Web page description (including the heading of the Web page and the description of the commodity) and the label of the received products were compared to evaluate the description consistency. DNA barcoding technology was used for seafood species identification, and the scientific names retrieved from the sequence analysis after consulting the Barcode of Life Data systems and GenBank were compared with the expected species, genus, and family to determine the description authenticity. Only 25% of the samples had consistent descriptions on the Web page and on the label of the received product. Most of the inconsistency originated from the geographical origin, and only four products (G10, G50, G19, and G69) had inconsistent species, genus, and family descriptions. Molecular analysis revealed that in 65% of samples the species was correctly described. The online seafood market presents challenges regarding seafood fraud and opportunities for seafood species substitution. HIGHLIGHTS

AbstractObjectiveEncouraging people to eat more seafood can offer a direct, cost-effective way of improving overall health outcomes. However, dietary recommendations to increase seafood consumption have been criticised following concern over the capacity of the seafood industry to meet increased demand, while maintaining sustainable fish stocks. The current research sought to investigate Australian accredited practising dietitians’ (APD) and public health nutritionists’ (PHN) views on seafood sustainability and their dietary recommendations, to identify ways to better align nutrition and sustainability goals.DesignA self-administered online questionnaire exploring seafood consumption advice, perceptions of seafood sustainability and information sources of APD and PHN. Qualitative and quantitative data were collected via open and closed questions. Quantitative data were analysed with χ2 tests and reported using descriptive statistics. Content analysis was used for qualitative data.SettingAustralia.SubjectsAPD and PHN were targeted to participate; the sample includes respondents from urban and regional areas throughout Australia.ResultsResults indicate confusion around the concept of seafood sustainability and where to obtain information, which may limit health professionals’ ability to recommend the best types of seafood to maximise health and sustainability outcomes. Respondents demonstrated limited understanding of seafood sustainability, with 7·5 % (n 6/80) satisfied with their level of understanding.ConclusionsNutrition and sustainability goals can be better aligned by increasing awareness on seafood that is healthy and sustainable. For health professionals to confidently make recommendations, or identify trade-offs, more evidence-based information needs to be made accessible through forums such as dietetic organisations, industry groups and nutrition programmes.

Abstract:

Abstract Background Maternal seafood intake during pregnancy and prenatal mercury exposure may influence children’s growth trajectories. Methods This study, based on the Norwegian Mother, Father and Child Cohort Study (MoBa), includes 51 952 mother-child pairs recruited in pregnancy during 2002–08 and a subsample (n = 2277) with maternal mercury concentrations in whole blood. Individual growth trajectories were computed by modelling based on child’s reported weight and length/height from 1 month to 8 years. We used linear mixed-effects regression analysis and also conducted discordant-sibling analysis. Results Maternal lean fish was the main contributor to total seafood intake in pregnancy and was positively but weakly associated with child body mass index (BMI) growth trajectory. Higher prenatal mercury exposure (top decile) was associated with a reduction in child’s weight growth trajectory, with the estimates ranging from -130 g [95% Confidence Intervals (CI) = -247, -12 g] at 18 months to -608 g (95% CI = -1.102, -113 g) at 8 years. Maternal fatty fish consumption was positively associated with child weight and BMI growth trajectory, but only in the higher mercury-exposed children (P-interaction = 0.045). Other seafood consumption during pregnancy was negatively associated with child weight growth compared with no intake, and this association was stronger for higher mercury-exposed children (P-interaction = 0.004). No association was observed between discordant maternal seafood intake and child growth in the sibling analysis. Conclusions Within a population with moderate seafood consumption and low mercury exposure, we found that maternal seafood consumption in pregnancy was associated with child growth trajectories, and the direction of the association varied by seafood type and level of prenatal mercury exposure. Prenatal mercury exposure was negatively associated with child growth. Our findings on maternal seafood intake are likely non-causal.

Abstract:

Abstract Discriminant function analysis (DFA) was used to classify the freshness quality of lean fish, fatty fish, and shrimp as either acceptable (Class 1), marginal (Class 2), or unacceptable (Class 3). Fresh and frozen survey samples were statistically classified following an initial precategorization using sensory, chemical, and microbiological indices as predictor variables. Computer elimination of nonsignificant predictor tests, p > 0.05, was used to optimize the test protocol. DFA correctly classified 98.5% of 67 preclassed lean fish samples (34 Class 1; 13 Class 2; 20 Class 3), 86.2% of 58 preclassed fatty fish samples (22 Class 1; 16 Class 2; 20 Class 3), and 98.7% of 79 preclassed shrimp samples (45 Class 1; 18 Class 2; 16 Class 3) by using all the quality indices. Computer selection of significant predictor indices at p < 0.05 yielded correct predicted classifications of 95.5, 81.0, and 97.5%, respectively. The number of tests required to effectively categorize quality were reduced from 15 to 3 for lean fish, from 13 to 3 for fatty fish, and from 11 to 6 for shrimp, with minimal losses in prediction accuracy and a substantial reduction in analysis time.

Abstract:

An inventory of the most part of sulfur-containing volatile compounds (SCVCs) present in seafood was carried out. These molecules constitute key compounds to understand and improve seafood quality. According to their nature, concentration and environmental parameters (temperature), they can move the overall seafood odor from desirable to rotten. Sulfury odors can also indicate problems in sanitary quality. Thus, it is essential to monitor the generation of these compounds to better control the organoleptic and sanitary quality of seafood. SCVC were divided in two categories: aliphatic compounds and cyclic compounds. Among cyclic SCVC, several families of compounds can be distinguished as thiophenes, thiazoles and their respective derivatives. The main pathways of formation of SCVC in seafood are investigated in order to better understand their presence in seafood aroma. Microbial mediated enzymatic reactions are mainly implied in the generation of aliphatic SCVC whereas Maillard reactions are involved in the generation of cyclic SCVC. A small part of SCVC could also derive from the environment by direct bioaccumulation of S-containing molecules or precursors. Then, the occurrence of SCVC in seafood is discussed according to the extraction methods, analysis methods — sometimes olfactometric methods and the species — the state and the average biochemical composition of the seafood matrix in which they were recovered. Finally, among the identified SCVC, the odorant properties of odor-active volatile compounds were investigated. Aromatic notes and odorant thresholds for odorant SCVC of seafood aroma are listed. Both pathways of formation and lists of SCVC linked to their odorant properties constitute important indicators to optimise seafood quality from an organoleptic and sanitary point of view.

Abstract:

Background: Seafood is the main source of long-chain n-3 polyunsaturated fatty acids (n-3 PUFAs) with beneficial health effects; however, findings on the association between the consumption of different types of seafood and type 2 diabetes mellitus (T2DM) are conflicting. Our objective was to perform a systematic review and meta-analysis examining the relationship between different types of fish/seafood and the risk of T2DM in adult populations. Methods: A systematic search of PubMed/Medline, Scopus, and Web of Science (ISI) databases was performed for cohort studies, published in English, before 1 September 2017. Multivariate adjusted relative risk (RR) estimates with 95% confidence intervals (CIs) for each category of seafood were pooled to examine the association. Results: Comparing the highest vs. lowest fatty fish intake categories indicated that there was a significant inverse association between the consumption of fatty fish and onset of T2DM (RR: 0.89; 95 % CI: 0.82, 0.98; I2: 0%, P = 0.54). However, after performing sensitivity analysis, we found that eliminating one study resulted in a non-significant association (RR: 0.93; 95 % CI: 0.80, 1.09). There were no significant associations between lean fish (RR: 1.03; 95% CI: 0.87, 1.22, I2: 51.0%, P = 0.08), seafood other than fish (RR: 0.95; 95% CI: 0.83, 1.10, I2: 71.2%, P = 0.002), fish products (RR: 0.96; 95% CI: 0.82, 1.13, I2:0%, P = 0.62), and fried fish (RR: 1.02; 95% CI: 0.83, 1.26, I2:71.2%, P = 0.06) and T2DM risk. Conclusion: The risk of T2DM was not associated with the intake of lean fish, seafood other than fish, and fish products. However, due to the low robustness of findings regarding protective roles of oily fish, more longitudinal studies are needed to clarify this association.

Abstract:

Abstract Background: Triphenylmethane dyes and metabolites are known or suspected mutagens and are prohibited in animals intended for human consumption. Despite toxicity, triphenylmethane dyes are used illegally as inexpensive treatments for fungal and parasite infections in aquatic animals. Objective: AOAC INTERNTIONAL Official Method 2012.25 for the LC-MS/MS determination of malachite green, crystal violet, brilliant green, and metabolites leucomalachite green and leucocrystal violet in seafood products was previously validated for finfish (trout, salmon, catfish, and tilapia) and shrimp, but had not been fully validated for other types of aquacultured products such as eel, molluscan shellfish, or frog or for processed seafoods. Methods: Method 2012.25 was applied to a wide scope of raw and processed aquaculture products including Arctic char, barramundi, eel, frog legs, hybrid striped bass, pompano, scallops, seabream, smoked trout, dried shrimp, and highly processed canned eel and dace products. The canned products contained oil, salt, sugar, flavorings, spices, sauces, and/or preservatives. Results: Dyes and metabolites were recovered with >85% accuracy and precision generally <20% relative standard deviation. The method detection limit was ≤0.60 μg/kg and LOQ was <1.0 μg/kg. Compounds were identified in 99% of 330 fortified and incurred samples. Conclusions: This study supports the use of Method 2012.25 for triphenylmethane dye residue analysis in a wide variety of aquacultured and seafood products. Highlights: Method 2012.25 performed well with results consistent with previous validation studies, regardless of presence of additional food ingredients or the type of processing.

Full text

Abstract:

Corporate social responsibility (CSR) in the seafood industry is on the rise. Because of increasing public awareness and non-governmental organization (NGO) campaigns, seafood buyers have made various commitments to improve the sustainability of their wild seafood sourcing. As part of this effort, seafood suppliers have developed their own CSR programs in order to meet buyers’ sourcing requirements. However, the CSR of these companies, many of which are mid-supply chain or vertically integrated, remain largely invisible and unstudied. In order to better understand how mid-chain seafood suppliers engage in sustainability efforts, we reviewed the CSR practices of the 25 largest seafood companies globally (by revenue) that deal with wild seafood products. Based on literature, existing frameworks, and initial data analysis, we developed a structured framework to identify and categorize practices based on the issues addressed and the approach used. We found companies implement CSR to address four key areas, and through various activities that fit into five categories: Power; Practices; Partnerships; Public policy; and Philanthropy. One of the biggest gaps identified in this study is the lack of accountability mechanisms, as well as robust and consistent accounting of impacts. Indeed, many companies express commitments without clear goals and structures in place to ensure implementation. Therefore, improvements in seafood company performance on social and environmental aspects may not only require creating a better business case for CSR, but also require ensuring that companies have the necessary processes and structures in place through public oversights and regulations.

Abstract:

This study aims to construct a theoretical framework to analyze the elements of the network structure and the relationship system within the seafood supply chain. The scope of the investigation is to evaluate how these elements influence the flow of products and the efficiency of the seafood supply chain and why these social interactions can create value and enhance competitive advantage. The model combines the resource- and knowledge-based view and the social network analysis applied to seafood supply chains. To demonstrate the application of the model, two theoretical examples and a real case study of the Mercado del Mar in Guadalajara, Mexico, are used. Primary data are obtained from semi-structured interviews, social network analysis metrics, and qualitative analysis. Findings are based on the analysis of theoretical examples and must be considered with caution. Nevertheless, the observations in the examples and case study provide new arguments to the relationship between the pattern of interrelationship and the efficiency of a supply chain. This study emphasizes the necessity of combining quantitative and qualitative analyses to understand and explain real-life supply networks.

Abstract:

The relationship between omega-3 polyunsaturated fatty acids (n-3 PUFA) from seafood sources (eicosapentaenoic acid, EPA; docosahexaenoic acid, DHA) or plant sources (alpha-linolenic acid, ALA) and risk of type 2 diabetes mellitus (DM) remains unclear. We systematically searched multiple literature databases through June 2011 to identify prospective studies examining relations of dietaryn-3 PUFA, dietary fish and/or seafood, and circulatingn-3 PUFA biomarkers with incidence of DM. Data were independently extracted in duplicate by 2 investigators, including multivariate-adjusted relative risk (RR) estimates and corresponding 95 % CI. Generalized least-squares trend estimation was used to assess dose–response relationships, with pooled summary estimates calculated by both fixed-effect and random-effect models. From 288 identified abstracts, 16 studies met inclusion criteria, including 18 separate cohorts comprising 540 184 individuals and 25 670 cases of incident DM. Consumption of fish and/or seafood was not significantly associated with DM (n = 13 studies; RR per 100 g/d = 1·12, 95 % CI = 0·94, 1·34); nor were consumption of EPA+DHA (n = 16 cohorts; RR per 250 mg/d = 1·04, 95 % CI = 0·97, 1·10) nor circulating levels of EPA+DHA biomarkers (n = 5 cohorts; RR per 3 % of total fatty acids = 0·94, 95 % CI = 0·75, 1·17). Both dietary ALA (n = 7 studies; RR per 0·5 g/d = 0·93, 95 % CI = 0·83, 1·04) and circulating ALA biomarker levels (n = 6 studies; RR per 0·1 % of total fatty acid = 0·90, 95 % CI = 0·80, 1·00,P = 0·06) were associated with non-significant trend towards lower risk of DM. Substantial heterogeneity (I2~80 %) was observed among studies of fish/seafood or EPA+DHA and DM; moderate heterogeneity ( < 55 %) was seen for dietary and biomarker ALA and DM. In unadjusted meta-regressions, study location (Asia vs. North America/Europe), mean BMI, and duration of follow-up each modified the association between fish/seafood and EPA+DHA consumption and DM risk (P-interaction ≤ 0·02 each). We had limited statistical power to determine the independent effect of these sources of heterogeneity due to their high collinearity. The overall pooled findings do not support either major harms or benefits of fish/seafood or EPA+DHA on development of DM, and suggest that ALA may be associated with modestly lower risk. Reasons for potential heterogeneity of effects, which could include true biologic heterogeneity, publication bias, or chance, deserve further investigation.

Abstract:

There is a paucity of data regarding prevalence and characteristics of adult seafood allergy in United States cohorts. This study was designed to determine the characteristics of patient-reported seafood allergy in a large allergy referral adult population. Retrospective analysis was performed of laboratory and clinical characteristics of seafood-allergic patients in three allergy clinics in the Texas Medical Center between January 1,1997 and January 30,2010. Of 5162 patients seen in this adult allergy referral population, 159 had physician-diagnosed seafood allergy with an average age of diagnosis of 50.2 (18–81 years) years. Shellfish allergy (59.1%) was more frequent than fish allergy (13.8%). Crustacean allergy (82.6%) was more frequent than mollusk allergy (7.2%). Shrimp (72.5%), crab (34.8%), and lobster (17.4%) were the most common shellfish allergies and tuna (28.6%), catfish (23.8%), and salmon (23.8%) were the most common fish allergies. One-third of seafood-allergic patients reported reactions to more than one seafood. Shellfish-allergic adults were more likely to experience respiratory symptoms than fish-allergic adults (p < 0.05). The likelihood of having anaphylaxis (32%) was not statistically different between shellfish- and fish-allergic subjects. Severe reactions were 12.9 times more likely to occur within the 1st hour of ingestion compared with nonsevere reactions (p < 0.005). The percentage of seafood allergy in this adult allergy referral population was 3.08%.

Abstract:

Field laboratories of the U.S. Food and Drug Administration collected and tested 11,312 import and 768 domestic seafood samples over a 9-year period (1990 to 1998) for the presence of Salmonella. The overall incidence of Salmonella was 7.2% for import and 1.3% for domestic seafood. Nearly 10% of import and 2.8% of domestic raw seafood were positive for Salmonella. The overall incidence of Salmonella in ready-to-eat seafood and shellfish eaten raw was 0.47% for domestic—one shucked oyster and one shark cartilage powder. The incidence in the 2,734 ready-to-eat import seafood was 2.6%—cooked shrimp, shellfish or fish paste, smoked fish, salted/dried fish, and caviar. The incidence in import shellfish consumed raw was 1% in oyster, 3.4% in clams, and 0% in mussels. The incidence in raw, import fish was 12.2%. Distribution of Salmonella in seafood on a regional basis indicated the incidence to be highest in central Pacific and Africa and lowest in Europe/Russia and North America (12% versus 1.6%). Data on a country basis indicated Vietnam to have the highest (30%) and Republic of Korea the lowest (0.7%). While the most frequent serotypes in import seafood were Salmonella Weltevreden (1st), Salmonella Senftenberg (2nd), Salmonella Lexington, and Salmonella Paratyphi-B (3rd, equal numbers for each serotype), the top 20 list included Salmonella Enteritidis (5th), Salmonella Newport (6th), Salmonella Thompson (7th), Salmonella Typhimurium (12th), and Salmonella Anatum (13th), commonly involved in foodborne illness in the United States. Because the incidence in the present study is based on only a small fraction of the seafood imported into the United States, efforts should be directed toward implementation of hazard analysis and critical control points to reduce the incidence of Salmonella in seafood without relying on testing for Salmonella.

The seafood industry has experienced a gradual increase in exports each year which has an impact on the high value of competitiveness in companies. PT. Nirvana Niaga Sejahtera is a seafood industry engaged in the tuna commodity export trade. The concept of competitiveness analysis and the best supplier selection used is the Five Forces Analysis concept based on five strength indicators which are incoming company threats, buyers, consumers, substitute product manufacturers, analysis of supplier strengths and AHP methods use expert choice 11 software to produce the company's best supplier. The results of the Five Forces Analysis model show that investor threats to new companies and the number of similar companies can affect the bargaining power of buyers and the quality of suppliers. The selection model using AHP produces alternative for supplier that are Supplier A (Toli-Toli) 0.385, Supplier B (Kendari) 0.322, Supplier C (Ternate) 0.279.

Abstract:

<p>In this research paper a Constant Market Share (CMS) approach was employed to learn export performance dynamics of Indian seafood (shrimps and cephalopods) in the major export destinations (EU, USA and select Asian countries), which accounts for a sizeable market for Indian seafood. The Constant Market Share model was used to disintegrate the growth in exports of seafood into market size effect, market composition effect and competitiveness effect. The analysis was performed for the seafood exports for a span of 12 years from the year 1996 to the year 2007, the period during which India had to face severe challenges from evolving food safety regulations in the EU and USA. The analysis was extended to account for the competitiveness at dis-aggregated commodity level. In the present study we observed enhanced competitiveness in the case of cephalopods while shrimp exports were less competitive. To a certain extent it shows that trade facilitating as well as trade restricting effects can coexist as an impact of strict food safety regulations.</p>

Abstract:

ABSTRACT Methicillin-resistant Staphylococcus aureus (MRSA) has been a global health concern since the 1960s, and isolation of this pathogen from food-producing animals has been increasing. However, little information is available on the prevalence of MRSA and its clonal characteristics in seafood and the aquatic environment. In this study, 267 seafood and aquatic environment samples were collected from three districts of Kerala, India. Staphylococcal protein A (spa) typing and multilocus sequence typing (MLST) was performed for 65 MRSA strains isolated from 20 seafood and aquatic environment samples. The MRSA clonal profiles were t657-ST772, t002-ST5, t334-ST5, t311-ST5, t121-ST8, t186-ST88, t127-ST1, and two non-spa assignable strains. Whole spa gene sequence analysis along with MLST confirmed one strain as t711-ST6 and another as a novel MRSA clone identified for the first time in seafood and the aquatic environment with a t15669 spa type and a new MLST profile of ST420-256-236-66-82-411-477. The MRSA strains were clustered into five clonal complexes based on the goeBURST algorithm, indicating high diversity among MRSA strains in seafood and the aquatic environment. The novel clone formed a separate clonal complex with matches to three loci. This study recommends large-scale spa typing and MLST of MRSA isolates from seafood and the aquatic environment to determine the prevalence of new MRSA clones. This monitoring process can be useful for tracing local spread of MRSA isolates into the seafood production chain in a defined geographical area.
