✔️The Facts About Screwworm from the American Horse Council
The American Horse Council (AHC) is working to share critical information for horse owners regarding the current New World Screwworm (NWS) infestation recently announced in Texas.
On June 3, 2026, the U.S. Department of Agriculture confirmed New World Screwworm in the umbilical area of a calf in Zavala County, Texas. This expansion into the United States is alarming and AHC wants to make sure you know about the potential risks of this parasitic fly to horses.
While this might seem like an overwhelming and scary situation, we’ve dealt with this before and have confidence in current science based strategies. The United States historically was afflicted with Screwworm for hundreds of years before successfully eliminating it from the country in the 1960s using many of the same methods we use now.
We’ve eliminated it before, and have full faith we’ll do it again, but only if all horse owners do their part to stay vigilant and follow state guidelines for animal movement.
