Gold Coast trainer Marcus Wilson has been disqualified for 12 months on two cobalt related charges.
Queensland Racing Integrity Commission stewards heard cobalt was detected in urine samples taken from Steering at the Gold Coast on November 19 and Lyra at Ipswich on December 16.
Earlier this year, evidence was taken from Wilson and staff from the QRIC Racing Science Centre.
At a resumed inquiry, Wilson was charged with two counts under AR 178 which covers bringing a horse to a racecourse with an illegal substance.
Wilson pleaded guilty to both charges and his legal representative made detailed submissions regarding penalty.
He was disqualified for 12 months.
Wilson can seek an internal review or take the matter further to the Queensland Civil and Administrative Tribunal.
