EPM is widely considered the most important infectious neurologic disease of horses in North America and is caused by protozoal infection of the central nervous system. Horses are infected by consuming food or water contaminated with opossum s**t containing sporocysts.
Horses with EPM do not present a biosecurity risk to other animals because the disease is not transmissible between horses. An effective vaccine has yet to be developed, so the best preventative approach includes eliminating access of opossums to feed and water in order to minimize contact with opossum s**t and improving your horse's immune defenses by decreasing stress and optimizing health.

As always, consult your veterinarian for more information and for advice tailored to your horse's specific circumstances.
