Lawmakers push USDA to strengthen response to livestock pest spread in US
U.S. Senator Jacky Rosen and several lawmakers have asked the United States Department of Agriculture (USDA) to take stronger steps to control the spread of the New World Screwworm (NWS). This pest has recently been found in Texas and New Mexico, raising serious concerns for livestock producers and rural communities.
Officials confirmed that at least seven cases have been identified since early June 2026. The New World Screwworm is a harmful insect that can damage the living tissue of animals. It mainly affects cattle but can also harm wildlife, pets, and even humans in rare situations.
The senators warned that this outbreak could put extra pressure on farmers and ranchers who are already dealing with rising costs. They stressed that quick and effective action is needed to prevent further spreading and protect the agricultural sector.
The USDA has already taken initial steps to manage the outbreak. These include increased monitoring, releasing sterile flies to reduce breeding, and working closely with animal health authorities in affected states. Officials have also reassured the public that the nation’s food supply is safe.
However, lawmakers believe these actions are only the beginning. They have urged the USDA to expand its efforts and respond more aggressively to match the seriousness of the threat. A coordinated and rapid approach is seen as essential to limit damage.
Senator Rosen has been active in supporting agricultural issues. She previously introduced legislation to improve weather forecasting for farmers and supported policies aimed at protecting the domestic beef industry and stabilizing food prices.
The situation remains under close watch as authorities continue efforts to protect livestock, farmers, and rural economies from the growing threat of the New World Screwworm.
