> Livestock buyers in the Rio Grande Valley are becoming more cautious about purchasing cattle amid concerns over New World screwworm, although no active cases are currently reported in the area. Starr County remains under quarantine, and a nearly $800 million sterile-fly production facility is under construction in Edinburg, with completion expected late next year.
