Two new cases of New World Screwworm were detected in Edwards County, Texas, over the last 24 hours, according to the U.S. Department of Agriculture (USDA). This brings the total number of domestic detections to 15. The new cases were found in calves already inside the currently affected area.
The USDA said the new cases were anticipated, even with sterile fly dispersals underway, because it does not kill existing larvae but instead prevents future generations. Another case was detected in a lamb in Crockett County, Texas, which is west of the previously affected areas.
USDA Response
The USDA plans to start sterile fly dispersal flights over Crockett County to combat cases in the newly infested zone. The Texas Animal Health Commission has a map of infested and adjacent surveillance zones on its website.
