# Screwworm found in a West Texas chicken and in wild flies, and the state draws two more quarantine zones | Howe

> Texas animal health officials created new New World screwworm quarantine zones in far West Texas after the parasite was confirmed in a cow in Hudspeth County and a chicken in Presidio County. Federal traps also caught fertile wild screwworm flies in Pecos and Hudspeth counties, and movement limits now cover parts of 16 counties.

## Why it matters

Movement restrictions and inspection requirements on cattle and hides tighten livestock supply and raise the risk of wider cattle-movement limits, which supports feeder and live cattle prices. The spread toward major cattle regions also raises the chance of further trade restrictions.
