The meetings at Huntingdon, Doncaster, Ffos Las and Chelmsford have therefore been abandoned. In a statement on their website, the BHA said: “The British Horseracing Authority (BHA), with unanimous support of the BHA’s industry veterinary committee, has taken the decision to cancel racing at all British racecourses on Thursday 7 February 2019. This is following the BHA being informed this evening by the Animal Health Trust of three confirmed Equine Influenza positives from vaccinated horses in an active racing yard.
