A case of contagious equine metritis (CEM) in a non-thoroughbred stallion has been confirmed on a premises in Fife, Scotland, Friday 3 April 2020. The affected horse was imported in November 2019 from Europe and has had no clinical signs of infection.

The affected stallion has been isolated and is undergoing treatment. Freedom from disease will be confirmed in line with the International HBLB Codes of Practice requirements and breeding will not commence on this premises until freedom from infection is confirmed.
