Key Actions to Help Prevent the Spread of Strangles

1. Don't Present an Unwell Horse
Under Rule 320A, trainers are responsible for the care, control and supervision of horses in their charge. Any horse with a fever (greater than 38.5°C) or signs of infectious disease must not be transported to or presented at a racecourse, trial, sale or other equine event.

2. Monitor Every Horse – Twice Daily
Take and record the temperature of every horse in your stable twice a day. A temperature above 38.5°C is considered a fever and warrants immediate action. A horse with a temperature of 39.0°C or higher should be managed as a positive case until proven otherwise. Clinical signs such as nasal discharge or swollen glands are also important, but temperature is often the earliest indicator.

3. Isolate Early and Monitor Close Contacts
Immediately isolate any horse with a fever or clinical signs. Where possible, use a dedicated isolation area and minimise contact with other horses. Horses that have been in contact with affected horses should be closely monitored with twice-daily temperature checks and managed in accordance with your veterinarian's advice.

4. Strengthen Biosecurity and Hygiene
Strangles is highly contagious. Regularly clean and disinfect equipment, vehicles and high-contact areas, avoid sharing gear between horses, and practise good personal hygiene, including hand sanitising and changing gloves where appropriate. Good biosecurity is the most effective way to reduce spread.

5. Move Horses Responsibly
Avoid moving horses that are unwell or suspected of being infected. Where movement is necessary, follow veterinary advice and recommended health monitoring or testing before transporting horses to another property or attending race meetings, trials, sales or other equine events.

6. Seek Veterinary Advice Early
If you have any concerns, contact your veterinarian promptly. Early diagnosis, testing, isolation and appropriate management are the best ways to protect your horses, your stable and the wider industry.
