Bluetongue outbreak reported in Denmark as affected herds rise significantly

In the past two weeks, the bluetongue virus, which affects livestock such as cattle, sheep, and goats, has seen an outbreak in Denmark. The number of affected herds has grown from one to sixteen, and the Danish Veterinary and Food Administration assesses a high risk of further spread across the country. As summer comes to an end, questions arise about the virus’s future. Will it diminish as temperatures drop, or could it worsen? Although bluetongue does not infect humans, concerns linger regarding its impact as consumers.

The bluetongue virus was first detected in Denmark in August, marking the first occurrence since 2008. The initial case was found in a cattle and sheep herd in Tønder Municipality, and by August 22, outbreaks had been confirmed in several municipalities, including Aabenraa, Esbjerg, and Varde. The risk of transmission increases with rising temperatures, as the virus spreads through biting midges.

According to Mette Kirkeskov Sie from the Veterinary and Food Administration, the bluetongue outbreak may persist until late November. Infected animals cannot be slaughtered, and Danish exports, including live cattle and bull semen, are impacted due to the loss of the bluetongue-free status. The effect on consumer prices remains uncertain but could be significant if the number of sick animals increases.

Importantly, the bluetongue virus poses no health threat to humans, as it cannot be transmitted through consumption of meat from infected animals. Vaccination may still be a worthwhile investment for livestock welfare, especially with expectations of the virus’s returns next year.
