USDA Confident in Containing Screwworm Threat in Texas, Protecting Cattle Industry
U.S. Agriculture Secretary Brooke Rollins informed lawmakers that the USDA is confident in its ability to contain a case of New World screwworm detected in Texas. The parasite, which was found in a calf in southern Texas, poses a significant threat to the cattle industry, marking its first appearance in decades. The screwworm, a flesh-eating parasite, has been advancing north through Mexico over the past year. The USDA is currently producing 100 million sterile flies weekly in Panama to combat the parasite, but needs to increase production to 400-500 million flies weekly to effectively push back the threat. The detection has put ranchers and traders on high alert, as a wider infestation could further reduce the U.S. cattle herd, already at its smallest in 75 years.
