The Norwegian Veterinary Institute (NVI) received in late August 2013 material from the first case of diseased rainbow trout from a hatchery showing unfamiliar signs of disease. Samples from the second case were received in October and a third case was detected at the beginning of November 2013. Samples from what until now seems to be the most recent hatchery affected by this disease were received in January 2014. Fish affected by this disease were sized from 30 – 100 g. Mortalities have, according to information submitted been moderate in exception from one of the affected farms where the mortality has been rather high in some of the units.
FunTox is the name of a new scientific platform at the Norwegian Veterinary Institute. The platform is part of the Institute’s long-term commitment to excel within appointed areas, including moulds in a «One Health» perspective.
In January 14-17 in Institute of Food Safety, Animal Health and Environment „BIOR” together with bilateral cooperation partners Daugavpils University and Norwegian Veterinary Institute were implemented a project No.PV2013/011 „Organization od visit to promote collaboration Norwegian partners for project preparation within thematic area of health – prevalence of zoonozes, risk for human health and prevention”.
Consumers in hospitals, airplanes, canteens, and even in some households may have limited choice other than convenience foods. The safety and quality of convenience foods rely significantly on the performance of food business operators. Food manufactures encounter challenges to make the right trade-off decisions on safety, quality, and cost, in a timely manner, when unintended changes occur during production, transport or storage.
To provide as complete a picture as possible of the health situation in Norwegian fish-farming, this annual report is based on diagnostic data from the Norwegian Veterinary Institute laboratories in Harstad, Trondheim, Bergen, Sandnes and Oslo as well as information gathered from fish-health services along the entire coastline. Information is also gathered from other research institutions and the Norwegian Food Safety Authority. www.vetinst.no/eng/Publications/Fish-Health-Report
Pigs react to swine flu like humans. This makes them usefuel in experiments which will find out how the virus attacks the respiratory tract in humans.
Flavobacteria cause huge losses in fish farming worldwide. Researchers are now surveying the variation found amongst these bacteria to better control the disease.
New findings on the interaction between an influenza-related virus and the host provide a significant contribution to understanding disease mechanisms behind the serious fish disease Infectious salmon anemia (ISA).
In an experiment where Viral Hemorrhagic Septicemia Virus (VHSV) was transmitted to Norwegian herring, almost half of the infected herring died. Although these results cannot be transferred directly into nature, they suggest that the virus may have an impact on mortality rates in Norwegian herring stocks.
Transmission of infection from neighbouring fish farms is the main way that the viral disease Infectious Salmon Anaemia (ISA) spreads during epidemics.
