Headline and graphs:  The Texas Tribune, 6/12/2026

Berenice Garcia, Jayme Lozano Carver and Stephen Simpson report,  graphics by Hien An Ngo:

On June 3, the New World screwworm was detected in a three-week-old calf in Zavala County by the U.S. Department of Agriculture. Since then, the agency reported more screwworm infestations in Texas. 

The fly poses a multibillion-dollar crisis for the state’s cattle industry, which generates $41 billion a year. It could also increase already record-high beef prices nationwide. 

It’s unclear how many cases could hit Texas. Nearly 28,000 cases have been detected in Mexico since November 2024, according to Mexican officials.
