What exactly is the screwworm and why is it dangerous?
The screwworm is a parasitic fly whose larvae feed on living tissue, primarily affecting livestock, wildlife, and sometimes humans. It can cause severe tissue damage and even death if not controlled. Historically, the US eradicated the screwworm in the 1960s, but recent outbreaks in Central America have raised fears of its return.
-
How close is the screwworm to entering the US?
The latest detection in Nuevo León, Mexico, is less than 70 miles from the US border. This proximity has prompted increased surveillance and control efforts in border states like Texas, aiming to prevent the parasite from crossing into US territory.

What measures are authorities taking to prevent the spread?
US and Mexican authorities are deploying traps, releasing sterile flies, and monitoring livestock movements. These measures are designed to contain the outbreak and prevent the screwworm from establishing itself in US livestock populations.
-
Could the screwworm threaten US agriculture and economy?
Yes, if it enters the US, the screwworm could devastate livestock industries, leading to economic losses and increased costs for farmers. Preventing its entry is crucial to safeguarding the agricultural sector and maintaining biosecurity.
-
Are there other biosecurity risks currently in the news?
Besides the screwworm, other risks include invasive pests, plant diseases, and emerging viruses. Authorities worldwide are on alert for new threats that could impact health, agriculture, and ecosystems.

Why is border health security more important now?
Global travel, climate change, and increased trade have heightened the risk of disease and pest spread across borders. Strengthening border health security helps prevent outbreaks that could have widespread economic and ecological impacts.
