New World Screwworms are Near. Here’s What Farmers Should Do

Farming in America is one of the most important aspects of our society. We know it as the practice of growing crops and raising livestock so that we can get food, essential goods, and profit. If it weren’t for farmers, our communities certainly wouldn’t function properly.

Much beyond cultivating crops and animals, farming is also one of the main contributors of business. It provides access to jobs and moves the U.S. economy forward. Historically, farming has always been the backbone of rural America, serving as a critical part of our everyday lives.

But today, this central practice is facing a new and serious threat. With recent cases of New World screwworm, farming operations across the country are increasingly under parasite pressure. As current trends show, this could be a pivotal moment for the future of animal health and modern agriculture.

What is the New World screwworm?

The New World screwworm is a type of pest where larvae eat the living tissue of warm-blooded animals. Unlike most flies that feed on dead species, these insects rely heavily on cattle and humans. As the female screwworm flies lay their eggs in open wounds or sores, they feed on the flesh, which can often cause severe pain, infection, or even death if untreated.

Years ago, new world screwworms were once widespread throughout the United States, devastating livestock herds and costing farmers millions of dollars. While this pest invasion eventually went away by the 1980s, since then, it has been present in certain parts of South and Central America.

More recently, New world screwworms made a visible comeback in Mexico this year, with outbreaks reaching over 6,700. Since this infestation, it has disrupted Mexican agriculture, with economic losses valued at more than $1.3 billion

Experts warn that the U.S. could be next in this crisis as screwworm cases continue to move northward. If it were to cross our borders, that means millions of cattle and farmers would be most at risk of the dangers.

Moments like this are why farmers need practical solutions to reduce the likelihood of infestation. That is where steps like water management play an important role.

What can farmers do?

In an era where screwworms are nearing, Andrew Coppin, CEO of Ranchbot, believes the first step to prevention is smart water monitoring technology. By being able to track water levels in real time, detecting damage before it happens, and controlling where the water flows, this type of technology can keep farmers alert so that cattle get the proper nutrition and care they need.

“Our livestock, our economy, and our way of life depend on staying ahead of these threats with smart systems and proactive policy,” Coppin adds.

In addition to water solutions, there are immediate efforts farmers and ranchers can do to protect cattle and farmlands. These actions include:

  • Stay informed. Recognizing the early signs of screwworm infestation is critical to survival. If there are any noticeable wounds that are not healing or decreased appetite from the herd, those are clear symptoms that should prompt care. 
  • Practice good hygiene. Farmers should always keep lands and their cattle in healthy environments. Regular cleaning and disinfection can prevent the outbreak of pests.
  • Report any cases. Farmers who notice unusual behavior or illness should report this immediately. Early reporting allows authorities to confirm cases and prevent the spreading from happening.

What happens now?

Even if the resurgence of screwworms is here, farmers and ranchers shouldn’t lose all hope yet. If anything, this wave serves as a reminder to better manage and treat our homelands with respect.

For anyone worried about this incoming outbreak, know that preparedness is the first clear line of action. That could mean investing the time now to research, review protocols, and shift current standards in order to safeguard herds and livestock.

Even so, the U.S. eradicated the screwworm once before, and it can prevail again as long as we stay vigilant. The ongoing threat may be close, but with proper intention today, farmers will surely stay ahead it.
