One of the affected horses is a 4-year-old Quarter Horse gelding, who tested positive on December 9 after developing clinical signs on December 5, including fever, purulent discharge from a submandibular lymph node, ventral jaw swelling, and reduced appetite. He is now recovering.
In addition to the two positive cases, three horses are exposed.

About Pigeon Fever
Pigeon fever is a bacterial infection that affects cattle and horses. It can cause large abscesses, most commonly on the chest and under the belly. Horses become infected when bacteria enters through broken skin, such as small scrapes or wounds. Peak season for infection is late summer through fall.
Good horse health safety practices are key to 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 that their animal is affected, they should contact their veterinarian.
