Plumpton Racecourse Cancels Sunday Meeting Following Equine Flu Outbreak
Plumpton racecourse in Sussex has been forced to abandon its scheduled jumps meeting this Sunday after a highly contagious disease outbreak was confirmed in a nearby facility. The decision comes as a precautionary measure to protect the wider thoroughbred racing population from potential infection.
The cancellation follows the discovery of equine influenza and EHV-4 in an unvaccinated non-thoroughbred horse located at a livery yard immediately adjacent to the racecourse. While the infected animal has been isolated, recent testing confirms it is still actively shedding the virus, posing a significant risk to other horses in the vicinity.
The Risk of Transmission
The proximity of the infected livery yard to the track’s stable area was a primary factor in the decision to call off the seven-race card. Equine influenza is notorious for its ability to spread rapidly through a population, often traveling through the air over considerable distances.

James Given, the British Horseracing Authority (BHA) director of equine regulation, safety and welfare, emphasized the contagious nature of the virus, noting that appropriate steps must be taken to minimize the risk of onward transmission. The decision to cancel the event received unanimous support from the BHA’s independent veterinary group.
Understanding the Pathogens: Equine Flu and EHV-4
To understand why this outbreak triggered an immediate cancellation, it’s important to look at the nature of the viruses involved:
- Equine Influenza: A highly contagious respiratory disease. Because it can spread via aerosolized droplets, it can move quickly through stables and transport hubs, potentially sidelining large numbers of athletes.
- EHV-4 (Equine Herpesvirus-4): This virus primarily causes respiratory infections in horses. While often less severe than EHV-1, it still contributes to respiratory distress and can impact a horse’s performance and health.
The fact that the affected horse was unvaccinated increased the likelihood of infection and the subsequent shedding of the virus, making the surrounding environment higher risk.
Safety and Coordination Efforts
The racecourse officials worked in close coordination with several entities to monitor the situation throughout the week. This collaborative effort included:

- The BHA’s regulatory and veterinary teams.
- Independent infectious disease experts.
- The management of the affected livery yard.
By maintaining regular communication and utilizing rigorous testing, officials were able to determine that the risk to the thoroughbred population remained too high to proceed with the event.
Key Takeaways: Plumpton Outbreak
- Event Status: Sunday’s jumps meeting at Plumpton is officially cancelled.
- Cause: Confirmed cases of equine influenza and EHV-4 in a neighboring livery yard.
- Patient: An unvaccinated non-thoroughbred horse that is still actively shedding the virus.
- Primary Goal: To prevent the spread of contagious respiratory diseases to the wider racing community.
Frequently Asked Questions
Is equine flu dangerous to humans?
No. Equine influenza is a species-specific virus that affects horses and does not pose a threat to human health.

Why cancel the event if the horse is isolated?
Because equine flu can be airborne and the livery yard is immediately adjacent to the racecourse, isolation alone was not considered sufficient to eliminate the risk of transmission to other horses entering the grounds.
How is this managed in the future?
Vaccination remains the most effective tool for preventing outbreaks. The BHA and veterinary experts continue to monitor disease patterns to implement rapid response protocols, such as the one seen at Plumpton.
Looking Ahead
While the cancellation is a setback for participants and fans, the prioritization of equine welfare is paramount. The racing community will continue to monitor the status of the isolated animal and the surrounding yard to ensure that the environment is safe for future fixtures. For the most current updates on rescheduled dates, stakeholders are encouraged to follow official Racing Post reports and BHA announcements.
