Incidence of Salmonella and Campylobacter contamination in consumer products

The results of a study carried out over a 12-month period with the aim of examining the frequency of the pathogens are now available. Salmonella and Campylobacter in Icelandic fresh chicken products on the market. 

The premise of the study was that Iceland has now adopted most of the food rules and EU food legislation, so it is clear that the import of fresh meat products to Iceland could become a reality, but so far the government has banned such imports. Therefore, there was a need to gather data to assess the safety status of Icelandic fresh products on the market with regard to microbial contamination, and chicken manure was selected where the contamination of these pathogens is most prevalent.

Comprehensive data are available on frequencies Salmonella and Campylobacter in poultry farming in Iceland and at slaughter in recent years, but there has been a lack of information on the state of affairs in the consumer market. The study took 537 samples from May 2012 to April 2013 from the country's three largest producers. 183 consumer packages of whole chickens, 177 packages of breasts and 177 packages of wings were examined. All the samples in the study turned out to be negative for both Salmonella and Campylobacter. It is therefore clear that the situation in these countries is very good and as good or better than what is happening in other countries.

The report of the study can be found here.

The study was a collaborative project between Matís and Matvælastofnun (MAST).

Testing different types of impregnations and its effect on bio fouling

The use of copper oxide in the treatment paint of cow bags is highly criticized and has been banned in many places due to its negative effects on the environment. Within the European Union, the use has been grayed out due to these negative effects of the substance on the environment, but it has been difficult to ban it as no substances have been found that repel sediments as well from the sacs as copper oxide. In the Norðurkví project, there has been a project where an attempt has been made to find a substance that could replace the copper oxide, but no permanent solution has been found. The results of this experiment are presented in this report.

Usage of copper oxide in treating net ‐ bags in aquaculture is a controversial and has been banned in many countries due to its negative environmental impact. Within the EU, use of copper oxide has been put on a gray list but not banned because no substitute treating material has been found which has the same effect in keeping algae away from the nets ‐ bags. The North Cage project has been looking into finding alternative solutions to copper oxide, and the conclusion of this research is drafted in this report.

Preliminary project for research on the genetic composition of Icelandic herring compared to other stocks in the Northeast Atlantic: Biological diversity and processing properties / A pilot study on the multidisciplinary approach for the genetic stock identification of herring in the Northeast Atlantic: Biodiversity, functional and chemical properties

The purpose of the project was to:

· Develop a genetic analysis set with 20-25 genetic markers to assess the genetic composition and stock structure of herring in the Northeast Atlantic

· Use genetic makeup, milling and other biological factors to differentiate strains

· Study the relationship between stock units and the processing properties of herring

Knowledge of herring stocks is of great importance for the sustainable utilization and management of herring fisheries. A key factor for sustainable fisheries management and quota allocation is to know what stock units are in the fishing areas and how large they are. In this project, approx. 4,500 samples collected from nine possible stock units in the Northeast Atlantic in the years 2008 - 2012 (off Iceland, Norway, the Faroe Islands and Scotland). This extensive and extensive sample collection will then be used in further research projects. The results of a genetic analysis with 24 genetic markers showed that local herring stocks in fjords in Norway were significantly different from all other stock units. However, no significant differences were found for the possible stem units. Other more sensitive methods, such as DNA monopoly analysis (SNPs), may be able to differentiate between the strains, but this research has already begun in a new follow-up project. The biological information collected in the project did not differentiate between possible stem units. Studies of the Icelandic summer spawning herring and the Norwegian-Icelandic spring spawning herring showed differences in body color, water and fat content as well as stage of puberty and weight. No results have been obtained from the mill analyzes, but they will be published in connection with a doctoral project at the University of Iceland.

The aim of the project was:

· To develop a genetic approach based on 20-25 microsatellite loci to study the genetic variation of herring stocks in the Northeast Atlantic Ocean

· To use genetic, biological and otolith characters as discriminating parameters for stock identification

· To analyze physicochemical characteristics of different herring stocks

Sustainable fisheries management and quota decisions made by authorities are based on knowledge on fish stock structures and their sizes. Herring is a highly migratory fish species, and therefore it is likely to show low genetic differences among stocks. The mixed stock herring fishery creates considerable problems for the industry and the management of the stocks. In this project more than 4,500 individuals were sampled from 9 putative herring stocks in the Northeast Atlantic Ocean during the years 2008 and 2012. The sampling accomplished in the project is extensive and valuable for future research projects. The results of the genetic study based on 24 microsatellite genetic loci showed that the local Norwegian fjord stocks were significantly different from all other putative stocks. The other Northeast Atlantic herring stock units were not found to be significantly different. Power analyzes performed during this study revealed that sampling scheme, protocols and genetic design were sufficient to detect any level of genetic differentiation around 0.001. Therefore, a more sensitive type of genetic markers are needed for the problem addressed, such as SNPs (single nucleotide polymorphism) and that work has already started. Biological parameters alone did not have enough discriminating power for stock identification. The Icelandic summer ‐ spawning herring (ISSH) and the Norwegian spring ‐ spawning herring (NSSH) differed mainly in color and water / fat content. The herring from the two stocks were also found to be different in relation to maturity and weight. The methodology of otolith microstructure analyzes and their results will be published later in a PhD thesis at University of Iceland.

Fish anti-diabetic fish proteins

The purpose of this project was to screen for the bioactivity of peptides produced from three different fish species: cod (Gadus morhua), saithe (Pollachius virens) and char (Salvelinus alpinus). The proteins were hydrolyzed with four types of proteolytic enzymes, viz. Alcalase and Protamex from Novozyme and Protease M and Protease P from Amano enzyme, and their bioactivity studied. The peptides were also digested with digestive fluids containing digestive enzymes to examine whether digestion affected their bioactivity. The aim of the project was also to investigate the anti-diabetic effect of the peptides through chemical and cellular tests. The main results indicate that the peptides have a positive health effect, especially antioxidant activity and antihypertensive activity. At the same time, the antioxidant activity increased after digestion. It was difficult to measure the anti-diabetic effect of the peptides by cellular tests and it is necessary to develop this method better for further research on the anti-diabetic effect of bioactive substances. Overall, the project is an important part of acquiring knowledge of the composition and properties of fish peptides extracted from different raw materials with different enzymes. The methods that were set up will be used in the future to analyze and verify further bioactivity in products made from Icelandic seafood.

This AVS project was primarily aimed at screen for the peptide characteristics of three different fish species: Atlantic cod (Gadus morhua), saithe (Pollachius virens) and Artic charr (Salvelinus alpinus). The proteins were hydrolyzed using four different proteolytic enzymes: Alcalase and Protamex from Novozyme and Protease M and Protease P from Amano enzyme by measuring the bioactive properties of these peptides. Moreover, after analyzing the characteristics of these peptides, the goal was to apply simulated gastrointestinal digestion and compare the digested peptides to undigested peptides to see if there were increases in bioactivities. Finally, this project also focused on the anti ‐ diabetes properties by using in ‐ vitro chemical based assays and in ‐ vitro cellular based assays. In general, the project results indicate possible health benefits of the fish peptides, particularly good anti ‐ oxidant and anti ‐ hypertensive effects. Interestingly, there was an increase of antioxidant properties after applying simulated gastrointestinal digestion to the hydrolysates. However, cell ‐ based assays testing anti ‐ diabetes effects proved to be very challenging while chemical in ‐ vitro test did not show any anti ‐ diabetes properties of the fish hydrolysates. We suggest that more research efforts need to be directed towards the development of assays measuring anti ‐ diabetes effects.

Fish today!

Matís is launching a national campaign called Fishing day and is intended to make consumers more aware of the importance of fish consumption and fish-related products such as fish oil and other seafood. The aim of the campaign is to increase Icelanders' fish consumption, but the campaign is funded by the AVS fund.

Many are involved in this positive effort. There will be several 5-minute interludes on RÚV, where myths about seafood will be addressed and we will also prepare study material for primary and secondary schools on seafood handling, nutrition and cooking. The biggest factor, however, is in the form of an advertising campaign where the unique characteristics of each type of seafood are hammered out and consumers are encouraged to have fish in their food at least twice a week and of course to take fish oil.

The Fish Today campaign will formally begin this weekend and the opening ceremony will be held in Smáralind on Saturday 28 September between 12: 00-16: 00.

… And when the kids ask: "what's for dinner?", The answer is of course: "we are going to have Fish Day"!
