To ensure that an equine is free of contagious diseases on arrival, the organization adheres to a practice that either 1) quarantines an equine for a minimum of 7 days if the equine is arriving from a facility with minimal perceived risk or 21 days if the equine is arriving from a facility of unknown risk or 2) requires that a health certificate signed by a veterinarian and dated no more than seven days prior to arrival is provided to the organization either prior to or upon arrival of the equine attesting to the health status of the equine.
