That's how long it took to identify screwworm in Florida in 2016.
New World Screwworm killed 135 endangered Key deer before anyone confirmed what it was. No digital tool existed to get a wound photo from the field to an expert.
In 2026, screwworm is back — 161,400+ animal cases at the US-Mexico border, active within 70 miles of Texas. USDA committed $850M to respond.
Screwworm Tracker closes the gap: photograph, assess, submit — from the pasture, with or without cell signal.
No paperwork. No phone calls. No waiting for office hours.
Take a photo of the wound. The app records GPS coordinates automatically.
Walk through a visual checklist. You don't need to be an expert — the app guides you.
Your report goes directly to your state veterinarian with photos, location, and assessment attached.
Built for the field, not the office.
Official APHIS alerts plus news activity. See where screwworm is trending near you. Cluster bubbles show article density at a glance.
Full operation with zero cell signal. Take photos, complete the assessment, save your report. Everything syncs when you're back in range.

Reports route to state veterinarian offices. Links directly to screwworm.gov and the APHIS emergency hotline (866-536-7593).
