North America’s cattle industry has long been a force for strengthening the economy, producing goods, dairy, and meat for millions across the nation. But beneath this livestock glory, two recent outbreaks are suddenly putting ranchers and farmers on high alert as cattle face a deadly reality.
For the first time in history, the Iowa Department of Agriculture and Land Stewardship has confirmed a recent case of Theileriosis in a herd of cattle in southeast Iowa. In a sudden development this summer, these dangerous tick-borne parasites, known to be carried by Asian Longhorned Ticks (ALHT), are now signaling an urgent wakeup call for the cattle industry.
Theileriosis is a dangerous species that affects both red and white blood cells in animals, leading to severe anemia, jaundice, difficulty breathing, and even death in some cases. As a major constraint to the world of livestock, experts warn this is only the beginning.
“The recent detection of Theileriosis in Iowa highlights how critical it is for ranchers to adopt proactive, tech-enabled health management strategies,” Andrew Coppin said, CEO of Ranchbot. “Ranchers can no longer wait for disease to emerge before responding, and it’s important for ranchers and consumers alike to shift to a more proactive approach, which can be done with the help of technology.”
Unlike other tick-borne illnesses, Theileriosis can be especially devastating to younger cattle and calves. While this disease is primarily a concern for beef producers, some dairy cattle can also be affected. When they are spread by the invasive ALHT, they lay thousands of eggs at a time—a number that spikes when cattle are introduced to new pastures.
To the south, another parasite is also advancing more conversation around the world of cattle. The New World screwworm, a flesh-eating fly larvae, has recently been detected 350 miles south of the U.S.-Mexico border. In a similar scenario, these parasites are especially feared for its devastating impacts on livestock, where they suck living tissue out of warm-blooded animals. Eradicated from the U.S. in the 1960s, these parasitic flies can cause bacterial infections and death if not treated promptly.
With both Theileriosis and New World screwworms hitting the world of cattle, parasites are evidently expanding fast, and the U.S. must act with urgency now. For farmers, one way to resolve the issue is to re-evaluate how they invest in their current control methods and biosecurity efforts.
“My advice to ranchers: boost pasture surveillance, integrate more tech to identify problems before they become crises, and partner closely with vets. Early detection saves herds, protects profitability, and strengthens biosecurity across entire regions,” Coppin added.
When parasites are suspected, a combination of management practices and deworming practices must be implemented to fully rid the infestation. This might include sanitizing the landscape, consulting veterinarians, avoiding overstocking pastures, and optimizing cattle nutrition to enhance their immune response.
An outbreak of Theileriosis and New World screwworms not only impacts cattle, but also American populations who heavily depend on farming to survive. Parasites pose a threat to the nation’s food supply chain, reducing production of crops, increasing grocery store prices, and creating rippling effects across the economy. With beef and dairy as staple goods, any disruption to herd health risks supply for everyday consumers.
Beyond the economic concerns, there are also implications for the ranchers who work directly with the disease-attacked cattle. With a widespread outbreak comes costly machinery and time-consuming solutions, ultimately leading to interference of one’s overall wellbeing and financial standing.
As new parasitic sites continue to emerge, now is the time for ranchers, legislators, and consumers to recognize the proactive measures. While cattle are currently facing the repercussions head-on, soon will North America if quick decisions are not prioritized.
Protecting cattle is much more than a job for the ranchers. It’s about an all-encompassing effort so that both animals and humans can live harmoniously in an ever-evolving society. So the next time a parasite like Theileriosis and the New World screwworm strike, let’s rethink how to respond. Above all else, an immediate effort can preserve not only the animals’ livelihood, but also yours.
