McDonald horses return positive swabs
Four positive swabs have been returned by three recent winners from Clinton McDonald’s Caulfield stables, Racing Victoria has announced.
The results were received on Tuesday in a report from Racing Analytical Services Limited (RASL).
Post-race urine samples were taken from the McDonald runners – Mr Crane, Carleton and Shabtis in November.
The four samples were each shown to contain free and conjugated 3-Methoxytyramine at a concentration in excess of 4.0g/ml, therefore making it a prohibited substance in accordance with the Australian Rules of Racing.
3-Methoxytyramine is a by-product of dopamine which is a substance produced in the brain and exerts effects on the nervous system.
Mr Crane tested positive twice after samples were taken from him after wins at Echuca on November 3 and Seymour 16 days later.
Carleton provided a sample after his win at Echuca on November 3 as did Shabtis who won at Seymour on November 19.
Racing Victoria said McDonald was initially informed of the irregularities from Mr Crane and Carleton at Echuca on December 4 and from Shabtis and Mr Crane at Seymour on December 10.
McDonald was advised of RASL’s confirmatory findings on Tuesday and that RVL stewards were continuing their investigation.
