EIA - The "Coggins" Test - The Law
January, 2000

The EIA virus (Equine Infectious Anemia) is spread from an infected equine to a 'clean' equine by blood-to-blood contact. Biting flies and reused needles can mechanically carry the disease from one horse to another. Unsterilized medical instruments or blood transfusions can also put equint at risk.
Since September 1, 1999 - Texas Law has required that equine, including horses, donkeys, mules and asses, have a test for Equine Infectious Anemia (EIA), also known as "Coggins" or "Swamp Fever" test - within 12 months prior to any change of ownership, whether through trade, gift, or sale through private treaty or at a market. The law only exempts zebras, nursing foals less than eight months of age that are changing ownership with their test-negative dams and equine sold to slaughter.
Persons who sell equine and fail to comply with the law, passed as House Bill 1732 in the 76th Texas Legislature, commit a Class "C" misdemeanor. The 12 governor-appointed commissioners for the Texas Animal Health Commission, the state's livestock health regulatory agency, have adopted a regulation that mirrors the legislation.
Also note that a negative EIA test within the previous 12 months is required for equine transported to events, races, trail rides, assemblies, or other gatherings.
If you have any additional questions on EIA, or the "Coggins Test", please feel free to contact the clinic by phone or E-Mail.
