Officials say Theileria has been detected in Nebraska cattle

LINCOLN, Neb. (KLKN) — The Nebraska Department of Agriculture on Tuesday said Theileria, a tick-borne parasite that affects cattle, was detected in several Nebraska counties.

According to the department, the Asian Longhorned Tick is the primary carrier of the parasite.

Although the tick has not been found in Nebraska, officials said cattle imported into the state have tested positive for the disease.

The tick has already become established in 26 other states.

Theileria can cause anemia, jaundice, loss of appetite, exercise intolerance, weakness, and, in some cases, death in infected cattle.

“The best method of prevention is tick control and good management practices for your herd, including external parasite control,” said State Veterinarian Dr. Roger Dudley. “If Theileria is suspected, it should be reported to a veterinarian immediately.”

According to the department, there are no vaccines currently available to treat Theileria.

Producers should talk with their veterinarian to determine an external parasite control method that works best for their herd during the summer months when ticks are most prevalent and regularly inspect cattle for ticks, including their ears, under the tail, axillary regions, flanks, and udder skin folds.

Theileria is a reportable disease, and affected herds may be eligible for indemnity for losses associated with Theileria.
