AHDB statement regarding bluetongue virus (BTV-3)

29 August 2024

Bluetongue virus (BTV) is a viral disease of ruminants transmitted by biting midges. There are a number of (sero) types of BTV that are recognised, the most common ones in Europe being BTV-3, 4 and 8, and they can have a devastating impact on livestock.

Unlike types 4 and 8, there is no licenced vaccine for BTV-3 in the UK.

The counties at greatest risk of being affected by midges blown over from northern Europe include Norfolk, Suffolk and Kent and those on the south coast from Kent to Devon.

While there is currently no evidence of the virus circulating throughout Great Britain, AHDB is aware of cases in East Anglia.

Opportunities to minimise risk on farm are limited, but attention to biosecurity remains critical – reducing environments that attract midges, such as dirty vehicles.

The disease does not spread animal-to-animal.

Bluetongue does not represent a risk to human health. It is, however, a notifiable animal disease.

Imports of animals from countries with BTV-3 are restricted and farmers wishing to import from other countries are advised to consult with their vets to determine the risks.

AHDB will continue to liaise closely with the Government and industry to monitor the evolving situation, including vaccine development and the implications for the GB livestock sectors.
