Key takeaway Department of Agriculture said Sunday, bringing the total detections domestically up to 15.
Why this matters in The San Antonio
The detection of two new screwworm cases in Edwards County calves within the last 24 hours brings the total domestic detections to 15, a concerning trend for local livestock owners. Although the USDA anticipated these new cases, given the ongoing sterile fly dispersals, the fact that they occurred within an already affected area suggests that surveillance efforts are indeed working. The expansion of screwworm cases to Crockett County, west of the previously affected zones, will require additional sterile fly dispersal flights, further straining resources. Local farmers and ranchers in Bexar County and surrounding areas should remain vigilant, monitoring their animals closely and taking preventive measures to protect them from infestation. The Texas Animal Health Commission's map of infested and adjacent surveillance zones will be a crucial tool for those looking to stay informed about the spread of screwworm in the region.
