■ Isolate new animals
■ Monitor animals in quarantine for signs of clinical disease
■ Take care not to allow direct or indirect contact between horses (such as on people’s hands, clothing or equipment)
■ Disinfect food and water containers
■ Disinfect horseboxes before and after collecting new animals
■ Refrain from overcrowding the yard. Some horses infected with strangles can become carriers who don’t show any clinical signs. They can only be identified through testing and this should be carried out while the horse is in quarantine.
