The confirmation of New World Screwworm cases in Texas and New Mexico has put cattle producers across the country on alert. However, veterinarians and livestock industry leaders say producers in the Midwest should remain vigilant without overreacting.
New World Screwworm is caused by the larvae of a parasitic fly that lays its eggs in open wounds on livestock and wildlife. Once the eggs hatch, the larvae feed on living tissue, creating serious animal health concerns if left untreated.
Veterinarian Dr. Russ Daly says producers should understand that the fly itself is not likely to spread naturally into the Midwest.
While the fly’s range is limited, Daly says animal movement creates a different challenge. Cattle are transported across the country every day, making awareness important for producers regardless of their location.
Daly says producers should take the threat seriously, but he cautions against assuming the situation will become an industry-wide crisis overnight. Treatments are available, and animal health officials have experience responding to livestock disease and pest outbreaks.
Closer to the affected region, cattle producers and livestock markets are already adjusting to the reality of dealing with New World Screwworm. Ben Hale, owner of Western Livestock in Oklahoma City, says the industry’s focus has shifted from the initial shock of the first U.S. confirmation to the work of monitoring cattle and staying ahead of the problem.
The discovery of additional cases has not significantly shaken cattle markets. Hale says buyer confidence remains strong and cattle prices continue to perform well despite concerns surrounding the pest.
Industry leaders say the key moving forward will be continued vigilance. Producers are encouraged to monitor livestock for unusual wounds or signs of infestation, report suspicious cases promptly, and stay informed as state and federal animal health officials continue efforts to contain the outbreak.
For now, the message from both veterinarians and livestock marketers is consistent: New World Screwworm is a serious issue that deserves attention, but there is little indication that Midwest cattle producers need to panic.
