The horseracing community in Newmarket is tonight being informed that four positive tests for equine influenza have been returned this evening in vaccinated thoroughbreds at the yard of a licensed flat trainer in Newmarket.

The affected yard is that of Simon Crisford, who has been named in order to ensure that the Newmarket community is aware of the yard at which an infection has been identified. No non-urgent journeys should be made to this yard – including by the media – and anyone who wishes to travel to the yard is advised to first contact the trainer’s office.

This yard is one of the 174 which has been required to undergo testing due to the fact that runners from the stable competed at the fixture at Newcastle on 5 February, which had been identified as a potential risk fixture. At the moment the affected horses are all contained within this yard.

The Newmarket community – including licensed trainers, veterinary surgeries, farriers, racing school and all other relevant bodies – are being advised to continue to show increased vigilance in biosecurity. Full guidance is available through the NTF website: https://www.racehorsetrainers.org/publications/pdfs/cop.pdf

This information is being relayed to the Newmarket community immediately in order to ensure that appropriate action can be taken ahead of any morning activities. The BHA will be in further contact with Newmarket trainers tomorrow morning.

A further update will be issued as early as possible tomorrow. This will include further details of action that is being taken off the back of this incident, and how the process will operate for the decision which will be made tomorrow evening regarding whether it is possible to resume racing on Wednesday 13 February.
