RACING Queensland has confirmed three harness and two thoroughbred trainers will appear before Stewards’ inquiries after their horses returned cobalt samples above the legislated threshold of 200 micrograms per litre in urine.

Thoroughbred trainer Jamie McConachy’s horse Vandalised returned a sample in excess of the threshold following its win in the Rockhampton Cup on 21 June 2014.

The other thoroughbred sample was returned by Len Treloar’s horse In The Sky Rocket at Doomben on March 29, 2014. Mr Treloar no longer holds a licence with Racing Queensland and has not been able to be contacted.

Harness trainers Shawn Grimsey and Trevor Lambourn had two horses each return samples above the threshold while Ken Belford had one sample.

Pacific Cruza (April 8, 2014) and Designer Style (April 14, 2014) returned positives for Mr Grimsey at Albion Park, while Mister Manhattan (August 6, 2014) and Ohoka Mach (April 30, 2014) returned positives for Mr Lambourn at Redcliffe.

Mr Belford’s horse Jessica Dale returned a sample above the threshold at Albion Park on September 20, 2014.

Racing Queensland stewards will now commence inquiries with the trainers as soon as practicable
