Bringing Horses into the United States
USDA regulations for importing equines can be found on their Veterinary Services, Import/Export websiteExternal.
If the horse is not known to carry any diseases transmissible to humans, no CDC regulations would apply. However, the United States Department of Agriculture (USDA) requires various periods of quarantine depending on the country of origin of the horse. In countries with prevalent screwworm, the quarantine period is 7 days. Horses coming from countries with African horse sickness are quarantined for 60 days.
