Tennessee’s state veterinarian says two new cases of an illness that could kill horses have been found in Shelby County. State veterinarian Samantha Beaty said in a news release that two horses in Tennessee’s most populous county recently tested positive for equine infectious anemia. She says their stable is under quarantine while other horses get tested. Equine infectious anemia does not sicken humans, but the blood-borne illness is dangerous to horses because there is no vaccine or treatment. Horse owners are being asked to check for symptoms that may include fever, lethargy, loss of appetite or colic.
