The recent confirmation of a strangles case in Polk County has heightened awareness and concern among local horse owners. As with any contagious disease, prevention is always better than a cure. Understanding what strangles is, how it spreads, and what measures to take can help protect your horses.

What Is Strangles?
Strangles is a highly contagious respiratory disease caused by the bacterium Streptococcus equi. Its name derives from the severe swelling it can cause in the lymph nodes of a horse’s throat and jaw, which can sometimes restrict breathing.

 
Common symptoms include:

• Fever
• Nasal discharge
• Swelling or abscesses under the jaw or in the throat area

While the disease is rarely fatal, it can cause significant discomfort and causes quite a headache for barn management. The primary concern with strangles is its contagious nature—it spreads easily through direct contact or shared equipment.

 
How Is Strangles Diagnosed?
Symptoms resemble other respiratory illnesses so early and accurate diagnosis is crucial. Your veterinarian will perform a physical examination and use a culture swab for nasal discharge or abscessed areas to confirm the presence of Streptococcus equi. Early diagnosis allows for quick intervention and reduces the risk of spreading the infection to other horses.

Prevention Tips: How to Keep Your Horses Safe
Preventing strangles involves a combination of biosecurity measures and vigilant management practices:

Quarantine New Arrivals: Always isolate new horses for at least two weeks before introducing them to your herd. Monitor them carefully for any signs of illness during this period.

Maintain Cleanliness: Regularly disinfect shared items such as water buckets, grooming tools, and feed tubs. Avoid swapping equipment between horses to minimize cross-contamination.

Vaccination: Consult your veterinarian about the possibility of vaccinating your horses against strangles. Vaccination is sometimes recommended for horses that travel frequently.

Limit Exposure During Outbreaks: If a case has been reported nearby—like the recent incident in Polk County—it’s important to restrict your horses’ exposure to other barns, shows, or gatherings until the outbreak is contained.

The recent case in Polk County serves as a reminder of the importance of proactive management and quick response in preventing the spread of strangles. By implementing strict biosecurity measures, staying vigilant, and consulting with your veterinarian, you can significantly reduce the risk of infection and maintain a healthy, safe environment for your horses. Prevention remains your best tool in safeguarding your horses from this contagious disease.
