In order to limit the spread of this pathogen, a voluntary quarantine with enhanced biosecurity measures has been implemented on the affected premises; the animals at the stable are undergoing regular veterinary monitoring. All introductions to the farm have been tracked, and no movements of animals from the stable have occurred or are planned.
