There was a Hendra virus scare at Randwick racecourse on Thursday when a horse showed possible symptoms of the deadly infection.
Tests have since cleared the horse of having the virus, which has resulted in nine horse deaths in Queensland and northern NSW since June 20.
A statement from Racing NSW said the tests for Hendra were precautionary as the virus' symptoms presented similarly to those of a horse with colic.
Signs of both afflictions include excessive salivation, mild fever and depression.
"This incident, however, heightens the need for Randwick trainers and their staff, and indeed all NSW racehorse trainers, to be vigilant for the possibility of Hendra virus infection in horses in their care," Racing NSW chief executive Peter V'Landys said.
"Randwick is potentially vulnerable due to the large population of flying foxes known to inhabit the adjacent Centennial Park, with considerable numbers of these animals observed to visit the racecourse precinct to feed on the fruits of the many fig trees on course."
Racing NSW chief steward Ray Murrihy and chief veterinarian Craig Suann inspected stables at Randwick on Thursday afternoon to ensure trainers were taking measures to minimise the risk of a Hendra infection.
The virus is spread by flying foxes which can transfer it to horses who can in turn infect humans.
