Equine Protozoal Myeloencephalitis (EPM) is a devastating neurological disease that affects horses, causing a range of symptoms from mild to severe. It is estimated that up to 50% of horses in the United States have been exposed to the disease, making it a significant concern for horse owners and equine professionals. Preventing EPM is crucial to ensure the health and well-being of horses, and it requires a comprehensive understanding of the disease and its transmission.
Understanding EPM
EPM is caused by the protozoan parasite Sarcocystis neurona, which is commonly found in opossums. The parasite is transmitted to horses through contaminated food and water, and can also be spread through direct contact with an infected opossum’s feces. Once infected, the parasite attacks the horse’s central nervous system, leading to a range of symptoms including loss of coordination, weakness, and blindness.
The Importance of Prevention
Preventing EPM is essential to avoid the significant consequences of the disease, including permanent neurological damage and even death. Prevention requires a multi-faceted approach that involves good husbandry practices, proper nutrition, and effective management strategies. By understanding the risks and taking proactive steps, horse owners and equine professionals can significantly reduce the risk of EPM and ensure the health and well-being of their horses.
Overview of Prevention Strategies
In this guide, we will explore the various strategies for preventing EPM in horses, including:
- Good husbandry practices to reduce the risk of transmission
- Proper nutrition and supplementation to boost the horse’s immune system
- Effective management strategies to reduce the risk of exposure
- Regular testing and monitoring to detect the disease early
By implementing these strategies, horse owners and equine professionals can significantly reduce the risk of EPM and ensure the health and well-being of their horses.
How to Prevent EPM in Horses
EPM, or Equine Protozoal Myeloencephalitis, is a devastating neurological disease that affects horses. It is caused by the protozoan parasite Sarcocystis neurona, which is commonly found in opossums. The disease can cause a range of symptoms, including ataxia, weakness, and paralysis, and can be fatal if left untreated. Fortunately, there are steps that horse owners can take to prevent EPM in their horses.
Understanding the Transmission of EPM
The first step in preventing EPM is to understand how it is transmitted. The parasite Sarcocystis neurona is shed in the feces of infected opossums, and can contaminate food, water, and soil. Horses can become infected by ingesting the contaminated substances. The parasite can also be spread through contact with infected opossums, or by vectors such as flies and ticks.
Reducing the Risk of Infection
There are several ways to reduce the risk of EPM infection in horses:
-
Remove opossum attractants: Opossums are attracted to food sources, such as pet food and bird seed, so removing these attractants can help reduce the presence of opossums on your property.
-
Keep your property clean: Regularly cleaning up manure and debris can help reduce the risk of contamination.
-
Use opossum-proof fencing: Installing fencing that is at least 6 feet tall and extends at least 12 inches below ground can help prevent opossums from entering your property. (See Also: Is Orchard Grass Hay Good For Horses)
-
Use feed and water containers that are opossum-proof: Using containers that are designed to keep opossums out can help reduce the risk of contamination.
-
Avoid using contaminated soil: Avoid using soil from areas where opossums are present, as it may be contaminated with the parasite.
Vaccination
Vaccination is another important step in preventing EPM. There are several vaccines available that can help protect horses against EPM. These vaccines work by stimulating the horse’s immune system to produce antibodies against the parasite.
It is recommended to vaccinate horses annually, and to start vaccinating at a young age. Foals can be vaccinated as early as 3-4 months of age, and should receive a booster shot at 6-8 months of age.
Good Nutrition and Health
Good nutrition and health are essential in preventing EPM. A well-nourished horse with a healthy immune system is better equipped to fight off infection.
A diet that is rich in antioxidants, vitamins, and minerals can help support the horse’s immune system. Foods that are high in antioxidants, such as berries and leafy greens, can help reduce oxidative stress and inflammation.
Regular exercise and stress management are also important in maintaining a healthy immune system. Reducing stress through techniques such as massage, acupuncture, and relaxation exercises can help support the horse’s overall health.
Monitoring for Signs of EPM
Regular monitoring for signs of EPM is crucial in detecting the disease early. Early detection and treatment can significantly improve the outcome for horses with EPM.
Signs of EPM can include:
-
Ataxia (loss of coordination)
-
Weakness or paralysis of the face, legs, or tail (See Also: Is It Bad For Horses To Lay Down)
-
Loss of appetite or weight loss
-
Changes in behavior or personality
-
Seizures or tremors
If you suspect that your horse has EPM, it is essential to seek veterinary care immediately. Your veterinarian can perform a range of diagnostic tests, including blood tests and spinal fluid analysis, to confirm the diagnosis.
Treatment and Management
If your horse is diagnosed with EPM, treatment and management are crucial in improving the outcome. The goal of treatment is to eliminate the parasite and manage the symptoms.
Treatment typically involves the use of antiprotozoal medications, such as ponazuril or nitazoxanide, which can help eliminate the parasite. In addition to medication, supportive care, such as rest, nutrition, and physical therapy, can help manage the symptoms and improve the horse’s quality of life.
In some cases, surgery may be necessary to relieve compression on the spinal cord or to remove lesions.
Recap and Summary
In summary, preventing EPM in horses requires a combination of good nutrition and health, vaccination, reducing the risk of infection, and monitoring for signs of the disease. and prompt treatment and management if the disease is diagnosed.
By following these steps, horse owners can significantly reduce the risk of EPM in their horses and improve their overall health and well-being.

Frequently Asked Questions: How to Prevent EPM in Horses
What is EPM and how does it affect horses?
EPM (Equine Protozoal Myeloencephalitis) is a neurological disease caused by a protozoan parasite that affects the central nervous system of horses. It can cause a range of symptoms including ataxia, weakness, and behavioral changes. EPM can be devastating for horses, leading to severe disability and even death if left untreated.
How do horses get infected with EPM?
Horses can become infected with EPM through the ingestion of contaminated feces from an infected opossum, which is the primary carrier of the disease. This can happen when horses eat food or water contaminated with opossum feces, or when they come into contact with contaminated surfaces or objects.
How can I reduce the risk of EPM infection in my horse?
To reduce the risk of EPM infection, it’s essential to maintain good hygiene practices around your horse’s living area. This includes regularly cleaning and disinfecting feeding and watering equipment, removing any potential sources of contamination, and preventing opossums from entering your horse’s living space. You can also consider using EPM preventatives, such as medications or supplements, under the guidance of a veterinarian.
Are there any natural ways to prevent EPM in horses?
Yes, there are several natural ways to help prevent EPM in horses. These include providing a balanced diet rich in antioxidants, omega-3 fatty acids, and other essential nutrients, as well as adding supplements such as vitamin E, selenium, and magnesium. You can also consider using herbal remedies, such as turmeric and ginger, which have anti-inflammatory properties. However, it’s essential to consult with a veterinarian before making any changes to your horse’s diet or adding supplements.
How can I diagnose EPM in my horse?
Diagnosing EPM can be challenging, as the symptoms can be similar to those of other neurological diseases. If you suspect your horse has EPM, it’s essential to consult with a veterinarian, who will perform a physical examination, take a complete medical history, and conduct diagnostic tests, such as blood tests and imaging studies, to rule out other conditions. Your veterinarian may also perform a Western blot test, which is a specific test for EPM.
