We have all been seeing a lot of posts about the recent outbreak of EHV-1/EHM in Texas, Oklahoma and Louisiana. We all have concerns. We are here to help clarify and educate on what you can do to best protect your equine family.
Currently, there have not been any confirmed or suspected cases of EHV-1/EHM in Flathead County. The Montana State Veterinarian also issued a notice last night that Montana State does not have any clinical or confirmed horses with EHM.
To help prevent the spread of EHV-1/EHM The Montana Department of Livestock has issued an emergency rule that all horses entering Montana are required to have their CVI (health certificate) issued within 72 hours of entering. They have disabled all 6-month healths. If it is necessary to travel out of state with your horse please be aware that each state may have their own requirements.
Vaccination: We do suggest that you vaccinate your horse every four-six months for Flu Rhino (EHV) if they are being hauled or exposed to outside horses. That means if you vaccinated in the spring you should booster your horse now. Although none of the current EHV-1 vaccines carry a specific label for the prevention of EHM, some of the EHV-1 vaccines have been shown to reduce nasal shedding and, in some cases, reduce viremia and reduce the severity of the disease. We are available to help you determine the best plan for your horse.
Biosecurity: You want to do everything you can to reduce the chances of an infectious disease being carried onto your farm. You should isolate new and returning horses. Clean and disinfect equipment and tack thoroghly. Do not share buckets, tack or brushes. Try not to use community tying racks or hitching rails. Monitor for signs of illness: fever, nasal discharge, cough and neurological signs.
As always, the health and wellbeing of your horses is our first and foremost concern. Please contact us at LaSalle Equine if you have any questions or concerns. 406-257-9399
