Number of the Day: 1,641,985,725
We celebrate the release of over 1.64 Billion sterile flies, a testament to the USDA’s commitment to defeat New World screwworm. Sterile fly releases, combined with surveillance, reporting, and outreach are essential to ensuring the pest cannot rebuild its population and spread unchecked.
Together, these efforts help protect livestock, pets, wildlife, and our agricultural resources. #flymaxxing

🚨 USDA Confirms First Detection of New World Screwworm in U.S. Wildlife.
New World screwworm has been confirmed in an elk on a Pecos County, TX game ranch. USDA has prepared for NWS cases in wildlife and is working with TX partners to increase wildlife surveillance in the area.
The case was reported after the elk was harvested by a hunter, underscoring how vital hunters, landowners, and outdoor enthusiasts are in spotting and reporting NWS early.
As hunting seasons continue, stay alert for:
• Maggots in wounds or body openings
• Open or foul-smelling injuries
• Weak, isolated, or distressed animals
• Signs of infestation around the nose, mouth, ears, eyes, or genital areas
If you see anything suspicious, report it immediately. Quick action helps protect wildlife, livestock, and pets.

Since June 3, USDA has received 1,000 suspect New World screwworm case submissions nationwide, including 531 from TX. USDA has confirmed just 56. Only 5 are still active.
What’s driving progress:
• Quick reporting from people on the ground
• Strong, coordinated USDA/state/industry response
• Consistent tracking of suspect cases

NEW: @SecRollins announced the next steps in @USDA’s phased reopening of southern livestock ports:
🐂 COLUMBUS, NM: Planned reopening to cattle on October 26. Every animal must undergo multiple inspections before entering the U.S.
🐎 SANTA TERESA, NM: Horse imports are planned to resume on October 26. Import quarantine must take place at the USDA-approved facility on the U.S. side. Mexican-side import quarantine facilities remain closed.
🐂 NOGALES, AZ: Planned reopening to cattle imports on November 30, if conditions continue to support safe trade and required inspection arrangements and infrastructure are in place.
Protecting American livestock remains the priority.

🪰 USDA's New World screwworm sterile fly release efforts are at the forefront of our defense against New World screwworm. And with 42.8 million sterile flies released through ground release chambers in targeted areas along the U.S. southern border, we’re supplementing our aerial dispersal efforts with pinpoint accuracy. These efforts are crucial for protecting animals in high-risk areas. The pressure is on, screwworms! 🔥#Flymaxxing

More than 1.5 BILLION sterile New World screwworm flies have now been released across the U.S. southern border! By flooding the area with sterile flies, USDA teams are outpacing wild screwworm populations and breaking the screwworm lifecycle.

🪰 Fighting New World screwworm takes more than sterile flies. It takes precision. 🪰
Using constantly evolving data models, USDA teams fine-tune sterile fly release areas to target the right places at the right densities. This strategy maximizes impact, preventing New World screwworm from gaining ground and reinforcing the barrier that protects the U.S.
