Aussie trainer Danny O’Brien has fourth horse test positive for cobalt


Racing officials have confirmed that Australian trainer Danny O’Brien has had a fourth horse return a test with cobalt levels above the allowable limit.

Racing Victoria said yesterday they had received the positive test result from Racing Analytical Services Limited in respect of the horse Bullpit.

The results were from a post-race urine sample taken from Bullpit after the horse won the Jeep 55 Second Challenge Heat over 955 metres at Moonee Valley on December 19 last year.

The lab found that the urine sample contained cobalt – an essential mineral nutrient which affects multiple body systems and is toxic at high dosages – at a concentration above the allowable limit of 200 micrograms per litre.

The sample was tested at the Chem Centre in Western Australia and was confirmed by the Hong Kong Jockey Club Laboratory.

In mid-January, Racing Victoria announced that three horses trained by O’Brien – Caravan Rolls On, Bondeiger and De Little Engine – had tested positive for cobalt above the allowable limit.

The report from testing officials related to:

  • A pre-race urine sample taken from Caravan Rolls On when the horse ran eighth in the Group 3 Lexus Stakes over 2500m at Flemington on November 1 last year;
  • A pre-race urine sample taken from Bondeiger when the colt ran second in the Group 1 AAMI Victoria Derby over 2500m at Flemington on the same day; and
  • A post-race urine sample taken from De Little Engine when the gelding won the People@Work Handicap over 2300m at Sportsbet-Ballarat 21 days later.

O’Brien is a prominent trainer, with Caulfield Cup and Cox Plate wins to his credit.
