A gross parasite just parked itself next door to Texas, and agencies are sweating because this one eats living tissue.

Parasite sighting near the U.S. border
- Alright, this kicked off after the New World screwworm showed up in Tamaulipas, Mexico, sitting right across from Texas.
- That distance change flipped warning switches at both the federal and state levels.
- The concern zone covers people, pets, and livestock, not just ranch animals.
- The Centers for Disease Control and Prevention dropped a health alert telling local officials to be ready on short notice.
- The fly starts trouble by dropping eggs into open wounds or soft entry points like noses, ears, eyes, or mouths.
- Once those eggs break open, larvae dig straight into living tissue and keep feeding.
- Livestock take the hardest hit, but the warning stretches to humans and household pets.
- Anyone outdoors a lot, working around animals, or walking around with untreated cuts carries higher exposure.
- The fly activity zone already covers parts of Mexico and Central America.
- Every larva and egg has to be physically removed, no shortcuts.
- Bad cases can escalate into surgery.
- Ignoring an infection can turn deadly.
- The U.S. has relied on sterile fly release programs for decades to keep this parasite out.
- That approach wiped out the screwworm outbreak in the Florida Keys back in 2017.
- The current surge looks ugly, with 1,190 human infections, seven deaths, and over 148,000 animal cases reported.
- Texas Agriculture Commissioner Sid Miller flagged the pace of new cases as a red flag.
- The volume and speed suggest screwworm fly populations may already be settled in Tamaulipas.
- Sterile fly deployment has started, but border-area producers are being told to stay sharp.
- The cattle industry is openly worried about what happens if the spread keeps rolling.
- Billions in losses are being floated as a realistic outcome.
- The risk line covers animal health and human safety at the same time.
