ARCADIA, Ca. (CNN) – The company that runs a prominent horse racetrack in Arcadia, California, announced new safety measures Friday.
It’s in response to the deaths of 21 racehorses at Santa Anita Park since December 26th.
It was scheduled this weekend to host two races including the San Felipe handicap, an important prep race to qualify for the Kentucky Derby.
Nobody knows why so many horses have died while racing or training there.
Some people think an unusually rainy period may have affected the running surface.
Some of the new safety changes for the track include trainers must seek permission 24 hours in advance to “work” a horse.
More track veterinarians have been hired and a new position was created to oversee the well-being of horses and investigate horse injuries.
Santa Anita park has suspended racing at least through the weekend.
