The recent detection of the New World Screwworm in Texas has raised concerns among livestock communities. The parasite was found in a young calf in Zavala County, close to the U.S.-Mexico border. Despite this, officials have reassured that the country’s beef supply remains safe.
"It's been very well prepared for, it has arrived," Uden said. "The U.S. beef supply is safe. This is an infestation, not a disease. So, it can be treated and not have any bearing on the product. We'll still produce very wholesome, safe, high-quality product."
Experts explain that screwworm is not a disease, but an infestation caused by fly larvae feeding on live tissue. It can be treated if identified early. Authorities have improved coordination at both the state and federal levels to handle the issue effectively.
The risk remains low in northern regions due to cooler climates, which naturally reduce fly activity. However, livestock owners are advised to stay alert, especially when introducing animals from areas where the pest may exist. Careful inspection of animals is important to prevent spreading.
One of the main warning signs is the presence of larvae or maggots on a living animal. This is different from maggots on dead animals, which is a normal occurrence. Open wounds, surgical procedures, and umbilical areas in young animals can become entry points for the parasite.
A key method used to control screwworm is the release of sterile flies. These flies mate with wild ones but do not produce offspring, gradually reducing the population. However, the current challenge is the limited production capacity of these sterile flies. A new facility is under construction, but it is not yet fully operational.
Experts remain confident in long-term control efforts. Similar methods were successfully used in the past to eliminate screwworm outbreaks. Increased awareness and preparation in recent years have also strengthened response capabilities.
Livestock owners are encouraged to report suspected cases immediately and avoid moving animals until checked. Continuous vigilance, along with scientific advancements, will help control the situation and protect livestock health.
