Australian racing authorities are running screening tests for a new painkilling substance with concerns it is being used in thoroughbred and harness racing.
SMH.com.au reported on Tuesday that racing stewards have received intelligence that a venom found in sea sails has been imported into Australia.
The report also stated that the mystery substance has sub-types known to be significantly stronger than morphine and can exit a horse's system very quickly, numbing any pain prior to performing on the racetrack.
Both Racing NSW and Racing Victoria have confirmed that a test able to detect conotoxins does exist, which also includes a range of venoms. They are also able to re-test existing samples that have been frozen.
