A Doncaster Racecourse spokesman said: “Following today’s announcement we will be working with BHA and Animal Health Trust to make sure that our racecourses take every measure to maintain high levels of biosecurity.”
The spokesman added that they are unsure when racing may continue as more tests are ongoing.
Infected horses are believed to have raced on Wednesday, possibly infecting other horses.
Doncaster’s race was only one of four races cancelled. Huntingdon, Doncaster, Ffos Las and Chelmsford races were also scheduled for Thursday.
