Ranchers-Cattlemen Action Legal Fund, USA (R-CALF) recently submitted a letter to the Food and Drug Administration’s Center for Veterinary Medicine, requesting emergency approval for medication to treat cattle infected with theileriosis.

The disease has been spreading more prevalently in recent years, caused by the Asian longhorned tick, and R-CALF says the medicine buparvaquone should be approved to treat infected cattle.

“The impact of having to watch valuable cattle die because of the lack of access to an approved treatment is tremendous,” said R-CALF USA Animal Health Committee Chair Max Thornsberry, DVM. “American cattle producers face serious risks from theileriosis, and we urge prompt action.”
