Four trainers face charges for cobalt use following crackdown from stewards
Racing Victoria stewards have continued to clamp down on the use of the prohibited substance cobalt with four stables charged with offences on Thursday.
Father-daughter training duo Terry and Karina O'Sullivan face nine charges after three of their horses returned readings above the 200 micrograms per litre in urine threshold in 2015 and 2016.
Of the nine charges, three are for the administration of a prohibited substance for the purpose of affecting the performance or behaviour of a horse in a race, while the remaining six relate to the administration of a prohibited substance being detected in a raceday sample and the presentation of a horse to a race with a prohibited substance in its system.
High levels of cobalt, a metallic compound, can increase the production of red-blood cells, hence it is regarded as a potentially performance-enhancing substance.
A greater amount of red-blood cells increase the amount of oxygen that can be carried through the body, theoretically allowing peak performance levels to be maintained for a longer period.
Monica Croston, Matthew Leek and Trevor Andrews are the other trainers to face charges, which will be heard by the racing appeals and disciplinary board on a date to be decided.
