EIA in North Carolina Mule

North Carolina Johnston County

A mule tested positive for EIA in Johnston County, North Carolina.

A routine blood test resulted in the discovery of a positive equine infectious anemia (EIA) in a 14-year-old female mule in Johnston County, North Carolina. The mule was euthanized. The remaining equids at the facility were tested and were negative for EIA.

This is the first new case of EIA documented in North Carolina since 2005. 

The Johnston County facility is under a quarantine restricting movement of equine until further testing is completed by the N.C. Department of Agriculture and Consumer Services.  These horses will be observed and retested in 60 days. Neighboring facilities are being monitored for the disease. For more information go to
