PIRSA considering punishment on "very serious" EI breach

South Australia's Department of Primary Industries and Resources (PIRSA) is expected to decide next week whether it will fine a Victorian trainer who sparked an equine flu scare.

The trainer took a horse to Mount Gambier without a permit, forcing other horses to be confined to stables as a precaution.

Test results for equine influenza have come back negative and the horses can now be moved.

The Victorian trainer faces a fine of up to $20,000.

South Australia's Chief Steward, Graham Loch, says PIRSA and Thoroughbred Racing SA will investigate the breach.

"In fairness one must to take all these matters on face value and consider all the facts that are relevant," he said.

"But from the stewards' perspective and the industry's perspective we'd regard the breach as very serious."
