Managing the health of large animals requires strict adherence to state-level disease reporting standards. These confirmed cases highlight the importance of monitoring current local health alerts to ensure property and livestock safety.

Maintaining rigorous hygiene and isolating new or symptomatic horses are the best defenses against bacterial transmission. Keep a close watch on local animal health alerts and consult a veterinarian if you notice suspicious swelling or sores on your horses.
