About CEM Quarantine

Federal law requires that all breeding horses over the age of two traveling to the United States from a country that is known to have the disease Contagious Equine Metritis (CEM) must go to a CEM quarantine facility for rigorous testing and treatment. Geldings are not considered breeding horses.

cemThe Center for Equine Health serves at the U.S. Department of Agriculture's West Coast CEM Quarantine and Treatment Station. CEM is a venereal disease of horses caused by bacteria and spread through breeding.

Ultimately, CEM results in a mare's inability to conceive. Stallions can carry the bacteria but do not show clinical signs.
