Horses from Texas temporarily banned from Florida
Florida Agriculture and Consumer Services Commissioner Charles H. Bronson announced last week the imposition of import restrictions on horses coming into Florida from Texas following the discovery of hundreds of Texas horses positive for Theileria equi, one of two organisms responsible for causing Equine Piroplasmosis (EP).
Bronson is requiring horses from Texas to have blood tests to check for Theileria equi within 30 days of entry into Florida, have a health certificate, be checked for ticks that carry EP, and be sprayed with a pesticide no more than two weeks before their arrival in Florida.
EP is considered a foreign animal disease, not endemic to the United States. It is a blood-borne parasitic disease primarily transmitted between horses by ticks or contaminated needles and is not directly contagious from one horse to another. Ticks are the natural method of transmission of the EP organisms, and the tick species known to be efficient at transmitting EP is not believed to be in Florida.
Acutely affected horses can have depression, fever, anemia, jaundiced (yellow) mucous membranes, and can die from the disease. In its milder form, EP can also cause horses to have roughened hair coats, constipation, colic, generalized weakness, and lack of appetite. Some horses become chronic carriers of the disease, showing little clinical signs but have the ability to transmit the disease to other horses via ticks. Treatment of infected horses has not been shown to be effective in eliminating the organism (Theileria equi), and infected horses must remain under quarantine.
The establishment of Equine Piroplasmosis and associated vector ticks would seriously threaten the horses and equine industry of Florida, which produces goods and services of more than $3 billion annually.
“We are being very proactive in testing horses that came in contact with positive horses that were imported from Texas over the past few years since we are not sure how long the problem has existed in Texas,” Bronson said. ”This is a serious disease, and we must take all precautions necessary to prevent the spread of this disease as well as to prevent the introduction of any ticks that are carriers of the disease.”
Ten horses that were exposed to EP in Texas and traveled into Florida before the outbreak was discovered have been located, tested and quarantined. Five of those horses have tested positive for the organism. The State Veterinarian’s Office is working with the owners to test all horses exposed in Florida and to minimize the risk to other horses in the state. So far no horses that were exposed to horses imported from Texas have tested positive.
Because some states have placed import restrictions on all states with positive horses, the Florida State Veterinarian’s Office recommends that anyone traveling out of state with their horse to call the state of destination to ensure there are no additional requirements enacted associated with this outbreak.
