Important reminder!
If you're in Florida and keep horses, you’ve probably already heard: cases of pigeon fever and strangles are on the rise this spring. But before you spiral into a group chat meltdown or start reaching for the hazmat suits, read this.
First of all, this is not a fear-mongering article. It’s a reality check, a toolkit, and a voice reminding you that yes, this stuff is real, but no, panic is not the answer.
Pigeon fever is caused by Corynebacterium pseudotuberculosis and usually shows up as painful abscesses on the chest, belly, or hindquarters. It spreads through flies, pus, and contaminated surfaces. Most cases are external and fully recoverable. Internal abscesses are rare but more serious, with a mortality rate of up to 40 percent if untreated. In external cases, mortality is low when managed correctly.
Strangles, caused by Streptococcus equi, looks dramatic: fever, nasal discharge, swollen lymph nodes under the jaw, but the actual mortality rate is under 1 percent. Most horses recover fully. It’s contagious, yes, but almost never fatal. Complications can happen, but they are the exception, not the rule.
So…what do we do?
We breathe. We don’t assume every snotty nose is a crisis. We start showing up for our horses with small, consistent habits that actually prevent the spread of disease. Biosecurity isn’t just for big barns or show horses. It’s basic horse care. The best time to make it part of your routine was a year ago. The second-best time? Right now. Whether you're starting from scratch or doubling down, this is your moment to get it right.
Don’t share water buckets. Don’t use the same grooming tools on every horse. Don’t skip quarantine when a new horse arrives: 14 to 21 days really does matter. Wash your hands between horses. Disinfect your thermometers. Keep fly control tight: fans, sprays, and clean stalls are not optional. If you’re not already taking and tracking temperatures twice a day, start.
If you travel from barn to barn, like farriers, massage therapists, vets, bodyworkers, or trainers, this is the time to get your biosecurity together. Disinfect tools between barns. Change clothes if you've worked around a sick horse. Wash your hands or use sanitizer between clients. If you think you’ve been exposed, speak up. Your professionalism is in your transparency.
Barn managers, now is a good time to ask: are my service providers doing their part? If you don’t know, ask. Any true professional will welcome the question and be ready with an answer. If someone gets defensive or offended that you asked about basic hygiene and barn safety, they’re probably not someone you need in your program long-term.
If a horse at your barn shows symptoms, isolate them immediately. Call your vet. Disinfect everything they touch: cross ties, pitchforks, halters, your hands. Don’t assume it’s nothing, and definitely don’t assume you can “keep it quiet.”
Florida’s climate is a breeding ground for this kind of bacteria. This isn’t going to be a one-time issue, but it doesn’t have to become your barn’s worst nightmare, either. You are not helpless. You are not at the mercy of fate. The horses need us to act early, not just react loudly. Most outbreaks are completely preventable, but only if we all stop panicking and start doing the little things that actually protect them.
