The Canadian border has closed to horses coming from Florida due to an outbreak of equine piroplasmosis in the state. At press, fifteen properties remained under quarantine with five of those having at least one horse testing positive.
Though the disease is a tick born infection the States Veterinarian’s Office suspects that it is being spread through poor management practices, such as with contaminated needles, rather than by the from the insect. Tick surveillance was conducted and no foreign ticks or ticks carrying the EP causing organism have been found.
This disease is not directly contagious from one horse to another but requires direct blood transfer. Human infection with equine piroplasmosis is extremely rare.
