The United States Department of Agriculture (USDA) has announced a comprehensive plan to eradicate the screwworm, a destructive parasite that poses a serious threat to livestock, wildlife, and rural economies. The initiative is part of USDA’s broader animal health protection strategy and aims to safeguard the agricultural sector from potential outbreaks.
Screwworms, which infest warm-blooded animals, can cause severe wounds and economic losses if not controlled. While the U.S. successfully eliminated the pest decades ago, continued vigilance is required due to risks of reintroduction from neighboring regions. USDA officials stressed that early detection and rapid response remain critical.
The new eradication plan includes expanded surveillance programs, cross-border collaboration, and the use of sterile insect techniques, which involve releasing sterilized screwworm flies to prevent reproduction. This approach has been proven effective in past eradication efforts and is now being scaled up with advanced technology.
In addition, the USDA will work closely with state agencies, veterinarians, and livestock producers to ensure preparedness. Training programs, public awareness campaigns, and rapid reporting systems are being strengthened to quickly identify and contain any suspected cases.
Experts note that a strong eradication plan not only protects animal health but also supports food security, trade, and rural livelihoods. Farmers and ranchers have welcomed the announcement, saying the measures will provide reassurance and help maintain confidence in U.S. livestock production.
The USDA emphasized that its goal is not only to prevent future outbreaks but also to create a long-term framework for protecting agriculture from invasive pests and diseases.
