Mitch Freedman cobalt positive confirmed

Trainer Mitch Freedman is the latest Victorian horseman to have a horse in their care return an elevated reading to the prohibited substance cobalt.

A pre-race urine sample was taken from Pearl De Vere before finishing fourth of eight runners in a 1200-metre fillies and mares Benchmark 64 at Geelong on June 28.

Racing Analytical Services Limited (RASL) had detected cobalt within the sample at a mass concentration of 111 micrograms per litre in urine. The Racing Chemistry Laboratory then tested the reserve portion of the sample and detected cobalt at a concentration of 130 micrograms per litre in urine.

The expanded measurement uncertainty for cobalt determination at 100 micrograms per litre is 10 micrograms per litre at greater than 99.7 per cent confidence.

Cobalt is an essential mineral nutrient that is toxic at high dosages and is a prohibited substance in excess of 100 micrograms per litre in urine as per the Australian rules of racing.

Racing Victoria stewards initially informed Freedman of the irregularity on August 3 and on Thursday he was advised of the confirmatory findings, with stewards set to continue their investigation.

Six Victorian trainers have had sanctions imposed for breaches of cobalt rules since 2018.
