The Department of Agriculture, Food and the Marine (DAFM) in Ireland is warning livestock farmers about the risk of the bluetongue virus, which has infiltrated new regions of Europe and Britain. This virus can affect ruminants and camelids, with sheep often showing more severe symptoms and mortality rates ranging from 30-70%. The virus is spread by infected midges most active from April to November. The DAFM has suspended the importation of live ruminants from Britain due to the disease, but permits imports from other EU countries with specific certification. However, there is concern that animals from Europe may not meet Ireland's certification requirements. A new variant of the virus, BTV-12, has been identified in a sheep in the Netherlands, for which there is currently no vaccine.
