Cattle producers are urged to remain alert this winter as new research suggests Theileria a parasite that affects cattle may spread in more ways than previously understood. Theileria is commonly linked to ticks, but recent findings show other transmission routes may also place herds at risk.
Veterinary experts explain that changes in parasite movement and overlooked management habits can increase exposure. While ticks remain a major concern, additional vectors and equipment practices may contribute to the spread of infection within herds.
“Theileria is tick-borne, but can also be spread by sucking lice, possibly stable flies, limited placental transmission and contaminated needles or equipment,” she said. “This emphasizes the importance of single needle use and highlights how difficult vector control can be.”
These findings underline the importance of careful herd management. Improper hygiene during routine procedures such as vaccinations, treatments, or pregnancy checks may raise infection risk. Reusing needles or tools without cleaning can unintentionally move parasites between animals.
Producers are encouraged to follow strict single use of needle protocols. Equipment such as dehorners, taggers and castration tools should be cleaned and disinfected between animals. These simple steps can greatly reduce disease spread during daily operations.
External parasite control is another key focus. Winter conditions often increase lice problems which may act as additional carriers. Reviewing parasite management plans and ensuring lice control is included can help lower risk during colder months.
Monitoring cattle health is also essential. Incoming animals, especially replacements, should be closely observed for signs of weakness or anemia. These symptoms may indicate possible Theileria infection and require quick attention.
Working with a local veterinarian is strongly recommended. A diagnostic and response plan can help address unexplained anemia cases early and limit herd impact. Early detection improves animal welfare and reduces economic loss.
Educational resources are available for producers who want to learn more. The Beef Cattle Institute Cattle Chat podcast from December provides additional information on Theileria and current research findings.
By improving hygiene, strengthening parasite control, and staying informed, producers can better protect their herds from emerging disease risks this winter.
