What is the New World Screwworm and why is it a threat?
The New World Screwworm is a flesh-eating pest that lays its eggs in the open wounds of warm-blooded animals, including livestock and humans. This infestation poses a significant threat to the beef industry and wildlife, as it can lead to severe health issues and economic losses. The pest was previously eradicated in the U.S. in 1966, but recent outbreaks in Texas and Mexico have raised alarms.

How is the USDA planning to combat the infestation?
The USDA plans to breed and release millions of sterile New World Screwworm flies in Texas and Mexico. This method aims to reduce the population by preventing reproduction, following a successful eradication effort in the 1960s and 70s. A factory dedicated to this effort is set to open in Mexico by July 2026, marking a proactive approach to managing the infestation.

What historical methods have been used to eradicate screwworms?
Historically, the USDA successfully eradicated the New World Screwworm in the 1960s and 70s using a similar sterile insect technique. By releasing sterile males into the wild, they prevented mating with wild females, leading to a significant decline in the screwworm population. This method proved effective and is now being revisited in light of the recent resurgence.

Why is the USDA's action considered urgent?
The urgency of the USDA's actions stems from the potential devastation the screwworm infestation could cause to the livestock industry and wildlife. Experts emphasize that without immediate intervention, the economic impact could be severe, affecting farmers and the broader agricultural economy. The situation is critical, prompting swift and decisive measures.
