Equine Infectious Anemia

The Animal Health Section of the Vermont Agency of Agriculture, Food and Markets supports private veterinarians in surveying for the presence of Equine Infectious Anemia (EIA) in the state's equine population.  In addition to providing in-state diagnostic support for EIA, the Agency has promulgated rules that require EIA testing prior to moving horses interstate and also require testing in some cases of intrastate equine movement.

EIA is a viral disease that affects equine animals and that can be transmitted between horses by biting insects. Since there is no vaccine or effective treatment for EIA, the Animal Health Section regulates the importation of equine animals into Vermont closely in order to ensure that infected horses do not enter the state and pose a risk to resident horses. Although Vermont has not experienced a confirmed case of EIA in a number of years, import regulations in place currently help to ensure that Vermont remains free of this disease.

Testing requirements for imported horses

In general, all horses imported into Vermont on a temporary or permanent basis must test negative on a Coggin's test for EIA within 12 months of entry into the state.

Testing requirements for intrastate movement

Any equine animal that is purchased, sold, offered for sale, bartered, exchanged or given away within the state must be tested for and certified as negative to EIA by an accredited veterinarian within 60 days prior to the transfer of ownership of the equine animal.

Emergency testing authority

Any equine animal may be required to be tested for EIA if the State Veterinarian has reason to believe that the equine animal has been exposed to EIA and may pose a threat to other equine animals.
