Racing Victoria’s Compliance Assurance Team launched a surprise raid on Flemington trackwork on Monday morning, testing riders and conducting random inspections.
The CAT tested 75 riders for drugs and alcohol in their system while audits were conducted on stable employee registrations.
The blitz revealed no failures of breathalyser tests while no unlicensed stable employees were found.
Racing Victoria will receive the results of drug tests in about two weeks.
A very nervous two week wait for all concerned.
