The British Horseracing Authority has urged trainers and racing yards to tighten their isolation and monitoring routines after a vaccinated thoroughbred linked to the Goffs Arkle Sale tested positive for equine influenza.
The case involves a racehorse based at a yard adjacent to licensed training premises near Bridgnorth in Shropshire. According to the BHA update, the horse arrived from the Goffs Arkle Sale at Kildare Paddocks, which took place from June 9 to 11, and reached the isolation yard on June 12.
The authority said the horse was transported to Britain on the same lorry as eight other thoroughbreds purchased at the sale. Those horses have since gone to a mix of licensed yards, pre-training yards and other premises, with the BHA contacting owners and those responsible for them to advise on testing and next steps.
BHA says infected horse remains in isolation
The infected horse was not showing clinical signs when it arrived, but symptoms developed late on Saturday evening and testing later confirmed the infection. The BHA said the horse had been, and remains, in isolation under recommended infection-control measures for a new arrival entering licensed premises.
No horses will be permitted to move to or from the affected yard or the neighbouring licensed premises until officials are satisfied there is no wider risk to racing.
The BHA also noted that the yard had a runner at Uttoxeter on Saturday, June 13, but said the risk of onward contamination is considered very low because of the biosecurity measures in place. Trainers who had runners at that fixture have still been asked to stay alert for signs of flu in horses who competed there.
The development follows earlier warnings around equine flu this spring, including the authority’s fresh guidance after a rise in UK cases and the separate local concern that left Plumpton waiting on test results before its May meeting.
Sale purchases told to follow isolation rules
The key instruction for trainers who bought horses at the Arkle Sale is straightforward: isolate new arrivals properly, check vaccination status, and monitor both new and established horses every day.
The BHA has advised yards to ensure any new horse entering the premises is fully vaccinated and isolated for at least 14 days before mixing with the main string. It has also reminded all racing yards that horses already in training must be vaccinated in line with the Rules of Racing.
The symptoms being flagged are the familiar but serious markers of equine influenza: a raised temperature above 38.5C, a harsh cough, nasal discharge, lethargy, poor performance or loss of appetite. Any concern should be raised with a veterinary surgeon and reported to the BHA immediately.
Why this matters for racing yards
Equine influenza is not just a veterinary issue in isolation. For racing, it becomes a movement, staffing and fixture-risk issue the moment a confirmed case touches the thoroughbred population or horses recently moving between premises.
The BHA has been careful not to overstate the immediate threat, but the message to yards is clear enough. Sales horses, pre-training moves and new arrivals all carry extra risk when the wider disease picture is active, and a quiet fortnight in isolation can be the difference between a controlled case and a disruptive chain of contacts.
It is also another reminder of the BHA’s wider regulatory role at a busy point of the Flat season, coming only days after its detailed explanation of the Benvenuto Cellini Derby non-runner ruling.
For now, the most important line is the simplest one: the confirmed case is being managed in isolation, the linked horses have been traced, and the sport has been told to keep its guard up.
