Dangerous Tick Detected in Alabama

The Alabama Department of Agriculture and Industries is warning residents after the recent detection of the Asian longhorned tick on a dog in DeKalb County. This invasive tick species is a growing concern because it feeds on multiple hosts, including humans, livestock, pets, and wildlife, moving between animals and the environment.

The tick is known to spread Theileria orientalis, a serious disease that impacts cattle health and productivity. It may also transmit illnesses such as Rocky Mountain spotted fever and Heartland virus.

First identified outside a U.S. port in 2017 in Hunterdon County, New Jersey, the tick has since spread across several Eastern states. Experts note it is not native to the Western Hemisphere.

Livestock owners are urged to stay alert. Animals showing weight loss, lethargy, anemia, patchy hair coats, or poor overall condition should be checked immediately. Heavy infestations can weaken animals, reduce growth, and in severe cases, lead to death from blood loss.

Officials recommend early detection and prompt veterinary care to protect animal health and limit spread.
