Bluetongue Disease Surges Among UK Sheep, Threatening Livestock Health

Surging Cases Amid Hot Weather

There has been a concerning rise in bluetongue cases among UK sheep, prompting farmers to take urgent measures. The viral disease, which is transmitted by biting midges (culicoides), has seen over 590 reported cases last week alone. This number marks a sharp increase from the previous week when only 115 cases were recorded.

The disease, while not necessarily fatal, can have severe effects on sheep health. Symptoms include high fever and swelling of the lips and tongue, with the latter turning blue due to restricted blood flow. According to the National Sheep Association (NSA), these midges thrive in conditions of hot weather and high humidity, which have been prevalent across parts of England.

Preventive Measures

• Farmers are advised to move their livestock away from low-lying or sheltered areas where midge activity is higher.
• Additionally, they should vaccinate vulnerable animals before dawn and dusk when the midges are most active.

The National Farmers' Union (NFU) vice-president, Robyn Munt, highlighted the challenges this poses: 'Bluetongue is continuing to spread at an alarming rate and is a significant concern for livestock farmers across the country.' Concerns and Confusion

• Farmers like Dominic Elson in Devon express frustration over perceived lack of preparedness from government bodies. He reported losing one of his ewes to bluetongue, an event that was particularly disheartening given its long-term presence on the farm.
• The Animal and Plant Health Agency (APHA) reported that the virus is circulating primarily in the south-west of England and parts of Wales, where recent hot and humid weather has favored midge populations. With several months of potential activity remaining, experts advise continued vigilance and vaccination as the most effective method to protect livestock.
