# Valley cattle owners facing parasitic screwworm threat

> USDA Secretary Brooke Rollins and Texas Governor Greg Abbott announced that the USDA will build a domestic sterile fly production facility in Edinburg, Texas, on top of $20 million for renovating a fly facility in southern Mexico. The new world screwworm has been reported less than 400 miles south of the Rio Grande Valley in Mexico. Local ranchers say cattle prices are already high, with a 500-pound heifer costing well over $1,500.

## Why it matters

A growing screwworm threat near the Texas border raises the risk of herd losses and tighter cattle supply, which supports live cattle and beef prices, while the new sterile fly facility is a longer-term step to contain the pest.
