Farmers are being 'strongly urged' to vaccinate sheep and cattle to protect them from the rapid spread of bluetongue. The UK's chief vet says vaccination is the only way to deal with the disease. There are now 130 cases, more than double the number this time last week. The vast majority are in England, with most in the South West. Wales has four cases, there are none in Scotland or Northern Ireland, and here cases means farms affected rather than individual animals with the disease. Bluetongue can make sheep and cattle lethargic and lame, it can cause birth defects or spontaneous abortions and it can be fatal. The disease is spread by midges, originally they were blown over from Europe but now they, and the virus, survive the winter here. This year's heatwave means the virus and midges are replicating much more quickly. It doesn't affect human or food safety. There is a vaccine but take up has been low. We ask the National Sheep Association why that is, and speak to the Chief Veterinary Officer who says scientists expect the virus to peak in September. Across much of England and Wales the heatwave and drought has meant an early harvest and poor yields, in much of Scotland things are different. There’s been hot and dry weather earlier in the summer but now it’s rain that's making things difficult. Presenter = Charlotte Smith Producer = Rebecca Rooney
