Strangles Outbreak at Georgia Boarding Facility: 1 Confirmed, 15 Suspected Cases – What Horse Owners Need to Know

Georgia horse owners are on high alert after a boarding facility reported one laboratory-confirmed case and 15 suspected cases of strangles, a highly contagious bacterial infection in equines. As of June 2024, the Georgia Department of Agriculture confirmed the outbreak at a private facility in the northern part of the state, prompting immediate biosecurity measures and heightened vigilance across the equine community. This article provides a clear, evidence-based overview of strangles, its transmission, symptoms, prevention strategies, and what horse owners should do if they suspect exposure.

Understanding Strangles: A Contagious Equine Disease

Strangles, caused by the bacterium Streptococcus equi subspecies equi, is one of the most common infectious diseases affecting horses worldwide. The disease gets its name from the severe swelling of lymph nodes in the throat area, which can obstruct breathing and cause the animal to “strangle.” While not typically fatal in healthy adult horses, strangles can lead to serious complications, including bastard strangles (where abscesses form in internal organs) and purpura hemorrhagica, an immune-mediated condition that can be life-threatening.

The bacterium spreads primarily through direct contact with nasal discharge or pus from abscesses of infected horses, or indirectly via contaminated equipment, water buckets, feed tubs, clothing, or human hands. Streptococcus equi can survive in the environment for several weeks under favorable conditions, making thorough disinfection critical during an outbreak.

Current Outbreak Details: Georgia Boarding Facility

According to the Georgia Department of Agriculture’s Animal Industry Division, the outbreak was identified at a boarding facility in Bartow County, Georgia, in early June 2024. One horse tested positive via nasopharyngeal swab and bacterial culture, confirming Streptococcus equi infection. Fifteen additional horses at the facility are exhibiting clinical signs consistent with strangles—such as fever, nasal discharge, and swollen lymph nodes—and are under quarantine and observation as suspected cases.

The facility has implemented strict biosecurity protocols, including isolating affected horses, restricting visitor access, enhancing sanitation of shared equipment, and conducting daily temperature checks on all resident horses. The Georgia Department of Agriculture is working closely with the facility’s management and local veterinarians to monitor the situation and provide guidance on outbreak containment.

Recognizing the Symptoms of Strangles

Early detection is key to preventing the spread of strangles. Horse owners should monitor their animals for the following signs, which typically appear 3 to 14 days after exposure:

• Fever (often 103°F or higher)
• Thick, yellowish nasal discharge
• Swollen, painful lymph nodes under the jaw or in the throat latch area
• Difficulty swallowing or reluctance to eat
• Lethargy and depression
• Coughing (less common but possible)

In some cases, abscesses may rupture and drain pus, which is highly infectious. If any of these symptoms are observed, owners should immediately isolate the horse and contact their veterinarian for diagnostic testing.

Diagnosis and Treatment Options

Veterinarians diagnose strangles through a combination of clinical evaluation and laboratory testing. The gold standard is bacterial culture of nasopharyngeal swabs or abscess material, though polymerase chain reaction (PCR) testing offers faster results. Serological tests can indicate exposure but are not reliable for diagnosing active infection.

Treatment focuses on supportive care and, in some cases, antibiotics. Most uncomplicated cases resolve with rest, good nutrition, and symptomatic care (e.g., warm compresses to encourage abscess drainage). Antibiotics like penicillin are generally avoided during the active abscess phase, as they may prolong the disease by preventing abscess maturation and rupture. Although, antibiotics may be warranted in specific situations, such as
