In August 2026, the Animal and Plant Health Agency (APHA) confirmed the presence of the Shamonda virus in cattle on Jersey. The viral infection causes significant health issues for livestock including goats, sheep, and horses.
Why it matters
The virus can lead to reduced milk production and animal mortality, threatening the agricultural output of the region. This outbreak follows the identification of the virus in several European countries throughout 2026.
The APHA has confirmed the virus in Jersey, where dairy exports reached 4.1 million litres in 2025. Monitoring is ongoing as the virus spreads across Europe.
The players
Animal and Plant Health Agency
An executive agency responsible for safeguarding animal and plant health in the United Kingdom.
The details
Shamonda virus is transmitted primarily through bites from Culicoides biting midges. Infected cattle typically exhibit fever, lethargy, and diarrhea, which often results in reduced milk production and potential birth defects or abortions in calves. Because the virus does not spread through milk, dairy products remain safe for human consumption.
Timeline
2025: Jersey exported 4.1 million litres of milk products.
August 2026: APHA detected Shamonda virus in Jersey cattle.
The Home Front
This detection aligns with the broader 2026 European trend of Shamonda virus spread affecting livestock health. It highlights the vulnerability of regional agricultural sectors to vector-borne diseases that disrupt production levels.
Owners of livestock should monitor animals for signs of lethargy, fever, or diarrhea. Please report any suspected cases to the APHA at 03000 200 301, or 0300 303 8268 if located in Wales.
The takeaway
While the virus poses no risk to human health, it is a significant concern for animal welfare and agricultural stability. Keep the APHA contact number 03000 200 301 accessible to report any clinical signs of illness in your herd immediately.
