Victorian trainer Mitchell Freedman is under investigation after one of his stable’s horses returned an illegal cobalt level in a pre-race urine sample taken in June.
Racing Analytical Services Limited reported that a test taken from Pearl de Vere at Geelong Racecourse on June 28 detected cobalt at a mass concentration of 111 micrograms per litre in urine with the reserve sample showing 130 micrograms per litre.
The allowable limit for cobalt is a threshold of 100 micrograms per litre.
Stewards initially told Freedman of the irregularity on August 3 and Racing Victoria said on Thursday that the investigation was continuing,
Cobalt is an essential mineral nutrient which affects multiple body systems and which can be toxic at high dosages.
