# Congressman Cuellar reacts to new case of screwwowm parasite detected in Nuevo Leon

> A new New World screwworm case was detected in Sabinas Hidalgo, Nuevo Leon, about 70 miles from Roma in Texas. Mexico has reported more than 500 active cattle cases across southern states, and the US has blocked imports of live Mexican cattle for a second time. Congressman Henry Cuellar urged the USDA to work faster with Mexican authorities, and there are no reported cases in Texas.

## Why it matters

Continued Mexican cattle import restrictions tighten US feeder cattle supply, and any spread into Texas would further cut available cattle, supporting cattle prices.
