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.

To read about importing horses into the United States, please see page 21 of our publication Global Health and the Sport Horse.

Dear Clients,

The CEH strives to meet all of your needs while your horse is in our care. If you would like to visit your horse, we ask that you schedule your visitation time with the main office by calling (530) 752-6433. Upon your arrival, one of our technicians will escort you to your horse's stall and answer any questions you may have.

Daily grooming helps horses adjust to their new environment and establish trust in those who are caring for them. A new feature we have recently added to our rehabilitation, layup and quarantine programs is the Equine Care Kit, which contains a few supplies that will be stored in your horse's stall and used only for your horse. Included in the kit are a curry comb, soft brush, thermometer, gloves, and salt lick. The assignment of these items to individual horses is intended to prevent the spread of infectious diseases. There is a one-time fee for the Equine Care Kit of $27.50, which will be included in the cost estimate provided by our client services staff. The kit will be sent home with your horse upon discharge.
