Norway Reports First Cases of Bluetongue Disease in Livestock Since 2009

Sep 20, 2024

Norway reported Thursday dozens of confirmed and suspected cases of bluetongue, an insect-borne virus that is harmless to humans but can be fatal to sheep and other livestock, for the first time in the country since 2009.

The Norwegian Veterinary Institute said the virus known as bluetongue serotype 3, or BTV-3, was first detected in livestock in southern Norway on Sept. 6.

The institute said the cases followed outbreaks of bluetongue in several European countries. Cases have also recently been reported in Sweden, Denmark, Germany, the Netherlands and France. The disease is spread by midges and ticks that are typically found in warmer weather.

In Sweden, cases were reported this week along the country's west coast, and earlier this month, several cases in Denmark prompted zoos and animal parks to protectively vaccinate animals to try and contain the spread. The first case in Denmark was recorded in early August, on a Danish farm with sheep and cows near the German border.

Video: Swine Industry Advances: Biodigesters Lower Emissions and Increase Profits

Analysis of greenhouse gas (GHG emissions) in the Canadian swine sector found that CH4 emissions from manure were the largest contributor to the overall emissions, followed by emissions from energy use and crop production.

This innovative project, "Improving Swine Manure-Digestate Management Practices Towards Carbon Neutrality With Net Zero Emission Concepts," from Dr. Rajinikanth Rajagopal, under Swine Cluster 4, seeks to develop strategies to mitigate greenhouse gas emissions.

While the management of manure can be very demanding and expensive for swine operations, it can also be viewed as an opportunity for GHG mitigation, as manure storage is an emission source built and managed by swine producers. Moreover, the majority of CH4 emissions from manure occur during a short period of time in the summer, which can potentially be mitigated with targeted intervention.

In tandem with understanding baseline emissions, Dr. Rajagopal's work focuses on evaluating emission mitigation options. Manure additives have the potential of reducing manure methane emissions. Additives can be deployed relatively quickly, enabling near-term emission reductions while biodigesters are being built. Furthermore, additives can be a long-term solution at farms where biogas is not feasible (e.g., when it’s too far from a central digester). Similarly, after biodigestion, additives can also be used to further reduce emissions from storage to minimize the carbon intensity of the bioenergy.
