Starr County Ranchers, there has been a significant development today (June 3, 2026) that explains why you are seeing so many reports on social media.
What Has Been Confirmed
A suspected case of New World Screwworm has been identified in South Texas. The report involves two calves on a ranch near La Pryor, Texas. Samples have been collected and sent to the USDA’s National Veterinary Services Laboratories in Ames, Iowa, for definitive testing.
What Has NOT Been Confirmed
As of this moment:
No confirmed New World Screwworm case has been announced in Texas.
The Texas Animal Health Commission (TAHC) continues to state that there are no confirmed detections in Texas livestock.
USDA has not yet confirmed that the larvae found in the South Texas calves are New World Screwworm. The samples remain under laboratory analysis.
Who Confirmed the Suspicion?
The information came directly from the United States Department of Agriculture (USDA), which publicly acknowledged that a suspect sample is being tested. USDA personnel have already been deployed to the area while awaiting laboratory confirmation.
Why the Social Media Confusion?
There are currently three different categories of reports being mixed together:
1. Confirmed cases in Mexico (true and officially documented).
* Coahuila cases as close as 25–31 miles from Texas.
2. The suspected South Texas case announced today.
* Under investigation.
* Not yet confirmed.
3. Rumors claiming Texas already has confirmed cases.
* Neither USDA nor TAHC has confirmed any Texas case at this time.
What I Am Watching For
The key announcement to watch for is from:
* USDA Animal and Plant Health Inspection Service (APHIS)
* Texas Animal Health Commission (TAHC)
* Texas Department of Agriculture (TDA)
If the Iowa laboratory confirms the larvae are New World Screwworm, that would become the first confirmed U.S. case associated with the current outbreak and would likely trigger immediate movement controls, enhanced surveillance, and sterile fly releases in the affected area.
What This Means for Starr County Ranchers
For ranchers such as yourself, I would now move Starr County from “prepare and monitor” to “high alert and inspect every wound.”
The reason is not because Texas has a confirmed case, but because:
* Confirmed cases are now extremely close to Texas.
* A suspected Texas case is under federal investigation.
* USDA is treating the report seriously enough to deploy personnel before confirmation.
If you would like, I can also prepare a Starr County Rancher Action Bulletin (Level 1 Response Plan) specifically for AMCLO Beefmasters and South Texas cattle operations for the next 30 days while the Texas case investigation is pending.
