UK chief veterinary officer, Christine Middlemiss, has today (Tuesday, September 17) set out further measures to mitigate the spread of bluetongue virus (BTV) serotype 3 (BTV-3), following 70 confirmed cases of infection.

BTV is primarily transmitted by midge bites and affects cattle, goats, sheep, goats, deer and camelids, such as llamas and alpacas, with case numbers now increasing dramatically in northern Europe.

The disease is damaging and can reduce milk yield, cause sickness, and reduce reproductive performance. In the most severe cases, it can cause death with all of these outcomes impacting farmers’ incomes.


New measures

  • A restricted zone (RZ) in Kent has been extended to cover the entire county and will now also cover East Sussex;
  • An extended restricted zone (RZ) will replace the temporary control zone (TCZ) in force in the East Riding of Yorkshire and parts of Lincolnshire;
  • East Riding and Lincolnshire have also been designated high-risk counties which means that keepers not covered by the new zone will be eligible for free testing. Keepers will also be eligible to vaccinate their animals using the new general licence.

This comes as the Secretary of State permitted the use of 3 unauthorised bluetongue serotype 3 (BTV-3) vaccines subject to license within the UK.

The vaccines can reduce some of the clinical signs experienced by animals with the disease, however they do not prevent infection.

All keepers of susceptible animals in the restricted zones will need to follow strict rules on animal and germ cell product movements.

These restrictions mean that susceptible animals cannot be moved out of the zone without a specific licence. A general licence to move animals to designated abattoirs is also available. Movements within a zone are also permitted.

Middlemiss said: “As the number of bluetongue cases continues to rise in England and northern Europe, we are taking prompt action to mitigate the spread of the disease.


“I urge farmers within bluetongue control zones to adhere to restrictions and remain vigilant to prevent the disease spreading to their herds.


“We appreciate the impact restrictions can have on farmers and are committed to working with everyone affected. We will continue to keep control zones under review as our understanding of the disease picture develops.”
