# Flesh-eating screwworm found within 31 miles of US border, says USDA | Reuters

> USDA has found New World screwworm within 31 miles of the US border. Experts warn that if the fly enters the US it could further spike record beef prices by keeping more calves out of the supply chain. USDA estimates an outbreak could cost the Texas economy $1.8 billion.
