The cobalt crisis that is sweeping Australian racing has exposed deep rifts in the equine veterinary community.

The Racing NSW inquiry into trainer Sam Kavanagh’s cobalt positive has resulted in allegations levelled at Dr Tom Brennan and his practice, Flemington Equine Clinic, that they supplied highly concentrated compounded cobalt, took cash payments and were involved in standover tactics.

In other evidence at the NSW hearing, FEC vets were said to have injected the preservative formaldehyde as a routine treatment for bleeders.

Such allegations again bought the licensing of veterinarians by racing authorities into the spotlight.
