Equine Infectious Anemia Testing Requirements on DNR Lands

Equine Infectious Anemia (EIA) is a viral disease affecting horses and other Equidae family members. EIA is found widely throughout the world. EIA is a reportable animal disease in all states and Wisconsin has requirements for testing. 

Movement within Wisconsin 

Per Department of Agriculture, Trade and Consumer Protection (DATCP) rules, horses and other equine animals moving within Wisconsin require proof of a negative EIA test within the previous 12 months for certain activities, including special events on DNR properties such as horseback dog trial events and organized trail rides. This testing requirement does not apply to personal trail rides that do not meet the definition of a special event. The definition of a special event can be found on the special event web page

Importing from outside Wisconsin

Per Wis. Admin. Code § ATCP 10.36, horses and other equine animals entering Wisconsin need the following:

  • A current certificate of veterinary inspection (CVI) (no more than 30 days old) which includes:
    • A complete physical origin and destination address.
    • Official individual identification for all animals, regardless of age.
  • A negative test for EIA within 12 months before the date of import. Nursing foals accompanying an EIA-negative dam are exempt from pre-import testing as long as the nursing status is identified on the CVI. The EIA test date and result must be written on the CVI.
  • If there is a current vesicular stomatitis diagnosis or quarantine in the state of origin, Wisconsin no longer requires a permit or special statements.

More information on Wisconsin’s equine movement and importing laws can be found on the Department of Agriculture, Trade and Consumer Protection (DATCP) website.
