Learn About Growing Tick Disease in Cattle at Stone County Livestock & Forage Event

Jan 21, 2026

University of Missouri Extension state veterinarian Craig Payne will talk about a growing tick disease in cattle at the 95th Stone County Livestock and Forage Conference 6-8:30 p.m. Thursday, Feb. 5, at the First Baptist Church in Crane.

“This long-running conference will equip livestock producers to better manage their operations, stay economically viable and provide quality beef products for our nation,” said Tim Schnakenberg, MU Extension field specialist in agronomy.

Payne will address Theileria orientalis ikeda, a protozoal organism. It primarily affects cattle by infecting red blood cells, resulting in anemia. Pregnant heifers and calves are particularly susceptible. Once infected, cattle can be lifetime carriers, and there is no cure.

The disease is primarily spread by the invasive Asian longhorned tick, the most common tick in Missouri. First discovered in 2017 in the United States, it is now in 23 states and is prevalent throughout Missouri.

Also addressed during the event will be a question many producers ask when trying to build their herds: “Should I buy or raise replacements?” Field specialist in ag business Jennifer Lutes will discuss the economic considerations.

Video: Five Confirmed New World Screwworm Cases Raise Alarm for Livestock and Pet Owners

Pat Hoffmann, Swine Technical Consultant at Elanco Animal Health tells us about the impact of New World Screwworm. The emergence of New World screwworm in the U.S. creates a threat for veterinarians, livestock producers and pet owners that has not been seen north of the Florida Keys since the fly was eradicated from the United States more than 50 years ago. New World screwworm (Cochliomyia hominivorax) larvae feed on living tissue and can affect a wide range of warm-blooded animals, including livestock, companion animals, wildlife, and even humans.
“New World screwworm could have a devastating impact on animal health, welfare, and producer livelihoods,” said Jeff Simmons, President and CEO, Elanco Animal Health. “We want to thank the FDA, EPA and USDA, for all their work to prepare for this threat. We’re committed to supporting our customers during this challenging time by delivering innovation, scientific expertise, and available resources to help treat New World screwworm and support the health and well-being of animals.”
Elanco is working alongside the U.S. animal health industry to help them fight against this parasite, offering a portfolio of options for pets and livestock that can help treat New World screwworm larvae infestations.
