About Pigeon Fever
Pigeon fever is a bacterial infection that affects cattle and horses, causing large abscesses, usually on the chest and under the belly. Horses get infected when bacteria enters through broken skin, like small scrapes or wounds. The peak season for infection is late summer through fall.
Maintaining good horse health safety practices is crucial in limiting the spread of pigeon fever. These practices include:
- Fly control;
- Not sharing water buckets or equipment; and
- Avoiding tying horses in high-traffic areas.
If a horse owner suspects their animal is affected, they should contact their veterinarian.
