Is now a good time to increase biosecurity measures to protect horses in your community?

Two horses in Florida have tested positive for strangles, a highly contagious respiratory infection. A total of 51 horses in Palm Beach and Orange Counties have been identified as exposed to the disease.

Why it matters

Strangles is a serious equine respiratory condition that requires significant containment measures to prevent further spread. The disease impacts stables and local equestrian operations by necessitating strict quarantine protocols.

Florida has recorded 28 confirmed cases of strangles in 2026. Currently, 23 horses in Palm Beach County and 28 in Orange County are reported as exposed to the infection.

The details

The disease spreads through direct contact with infected equids or contact with contaminated surfaces. Veterinarians typically confirm the diagnosis using polymerase chain reaction testing on nasal swabs, washes, or abscess samples.

Florida has recorded 28 confirmed cases of strangles throughout 2026.

Season Trajectory

This outbreak disrupts the local equestrian season, forcing stables to implement strict quarantine measures to maintain healthy populations. The uptick in cases shifts the focus toward biosecurity protocols for the remainder of the calendar year.

Stables in Palm Beach and Orange Counties must now manage the logistics of mandatory quarantine for 51 exposed horses. Owners should verify that their facilities are following updated testing protocols to prevent further spread of the infection.

The takeaway

Horse owners should prioritize strict isolation of animals showing signs of nasal discharge or lymph node swelling to mitigate the risk of transmission. Regular coordination with licensed veterinarians remains the most effective way to identify and manage new positive cases.
