Bluetongue Disease: Disease Control
Mr. Hoyle: To ask the Secretary of State for Environment, Food and Rural Affairs what mechanisms are in place to (a) prevent and (b) monitor the import and spread of bluetongue disease in summer 2009. 
(a) As of 3 November 2008, all of Great Britain became a single confluent protection zone for Bluetongue serotype 8 (BTV-8). Animals can be moved freely within this protection zone, and to and from other BTV-8 protection zones in Europe provided that they meet the generic import/export requirements and are accompanied by an Export Health Certificate which has been signed by an official veterinarian.
With specific regard to imports, DEFRA conducts post-import tests on all susceptible animals imported from continental Europe, for all Bluetongue serotypes. From 1 April 2009, this was increased to double testing to ensure that disease is picked up in both its early and late stages. DEFRA also urges industry to consider the risks and check the health and vaccination status of animals when sourcing any animals, from within the UK or abroad.
Spread of BTV-8 is additionally controlled through the use of vaccine. DEFRA underwrote 28 million doses of BTV-8 vaccine in 2008, enough for all susceptible animals in England. 12 million of these doses formed the supply at the start of 2009. This along with free market vaccine supplies from the three manufacturers authorised to market vaccine in the UK, Intervet, Merial and Fort Dodge should meet the demand for BTV-8 vaccine in 2009.
