About this episode

The episode discusses the confirmation of New World screwworm cases in South Texas and their potential impact on the cattle industry.

Two cases of New World screwworm were confirmed in the U.S. — in Zavala County. The parasite, carried by flies, targets the live flesh of warm-blooded animals, including cattle, pets, wildlife and humans, causing severe wounds or death. Spread of the New World screwworm could have a major economic impact on the cattle industry.
