Importation of Horses From Contagious Equine Metritis-Affected Countries

On March 25, 2011, we published an interim rule in the Federal Register to amend the regulations regarding the importation of horses from countries affected with contagious equine metritis (CEM) by incorporating an additional certification requirement for imported horses 731 days of age or less and adding new testing protocols for test mares and imported stallions and mares more than 731 days of age. That interim rule became effective on March 25, 2011; however, we are delaying the enforcement of the interim rule until July 25, 2011. This action is necessary to provide CEM testing facilities time to make adjustments to their operating procedures that are necessary for the rule to be successfully implemented.
