​​​​​​​​During the CEM process, no antibiotics, medicinal ointments or antifungal shampoos can be used which could affect the results of the testing, causing a delay in the release of the quarantine horses. Calder Farms will have the accepted shampoos available for use during your horse's stay.   As a licensed CEM quarantine facility, we strive to make the experience a pleasant one for both the horse and owner. 

To start the process, as an exporter you must provide the following:

  •  A current, negative Coggins report with the last 12 months

  • A copy of the original registration paper

  • A copy of an invoice or bill of sale for customs clearance at the point of destination.

Furthermore, an isolation agreement and transportation agreement must be completed and signed by both parties prior to start of any isolation period

Horses imported into the United States are required to be detained at the port of entry where they are tested for dourine, glanders, equine piroplasmosis and EIA. Any horse testing positive for any of these diseases will be refused entry. Once these tests are completed, mares and stallions from a CEM affected country, over 731 days old will be sent to an approved CEM facility to undergo further required testing.  Geldings don't need to undergo the procedure.

CEM or Contagious Equine Metritis is venereal disease caused by bacteria. The disease is spread through breeding. Infected mares would ultimately become infertile if the disease went undiagnosed. Stallions, considered carriers of CEM, usually remain asymptomatic. 

MARES:  Once blood is pulled, four sets of cultures are taken; the fourth taken prior to the washing and packing. The entire process generally takes 15 - 17 days if there are no complications with the cultures.

STALLIONS: The average stay for stallions is 35 days. Two recipient mares are provided. They are tested the same way as import mares with three sets of cultures taken three days apart. When all three negative results are in, they are ready for breeding. Once the stallion arrives,  blood is pulled and the stallion cultured. The stallion must live cover the two recipient mares. The two recipient then go through the culture process again. Stallions are the carriers, therefore the recipient mares are required to go through culture process again. Once the stallion has live covered, he will go through washing and packing for five days.

Exporting horses from the U.S. to another country requires a quarantine period at a USDA approved facility.  Calder Farms, LLC is governed by the USDA and Animal and Plant Health Inspection Services (APHIS) in order to meet all export requirements. Just prior to the start of isolation period for export horses, everything associated with those horses must be present at our facility. This means all the shavings, grain and hay must be stocked for the mandatory period. Owners are welcome to visit and ride if they so choose, however those items must also remain with the horses in isolation. Both the United States and the country of import have mandatory procedures that must be followed beginning with the pre-export quarantine and continuing with the medical examinations and tests. The USDA's requirements for maintaining the integrity of the quarantine facility are very specific and strict. At any time during the isolation period,

we are subject to unannounced inspections by USDA field officers.  The country of destination determines the minimum length of stay in the isolation facility as well as the immunizations and tests the horses must undergo. Click HERE  to find out the requirements of each country and updated information. During this time, the paperwork will also be completed. It is the USDA veterinarian who approves the horses to fly.  During this period of pre-export quarantine, we are dedicated to complying with the strict regulations set forth by the USDA while at the same time ensuring the isolation period for the horses is as stress free as possible.
