HCR 13 urges the federal government to take immediate action to prevent the spread of the New World screwworm (Cochliomyia hominivorax) into Texas. This parasitic fly, which poses serious threats to livestock, pets, wildlife, and humans, has been moving northward through Mexico and, as of mid-2025, has reached approximately 370 miles from the Texas border. Historically eradicated from the U.S. in the 1960s, the screwworm has resurged in parts of the Caribbean and South America, raising alarms about its potential reintroduction into the United States.
The resolution highlights the economic risk of a screwworm outbreak, with USDA estimates indicating potential losses of $1.8 billion to Texas from livestock deaths, labor costs, and treatment expenses. It urges the federal government to work collaboratively with Mexico using existing resources to develop a cross-border strategy. The resolution also calls on the U.S. Department of Agriculture (USDA) to expedite the construction of a screwworm control facility at Moore Air Force Base in Texas and to partner with Texas A&M AgriLife to include research capabilities in the new facility.
Additionally, the resolution requests the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) to fast-track approval of critical medications and pesticides needed for screwworm treatment and prevention. Finally, it directs the Texas Secretary of State to distribute official copies of the resolution to key federal agencies and leaders, including the President and members of the Texas congressional delegation, urging their support and swift action.
The differences between the originally filed version of HCR 13 and the Committee Substitute version are primarily editorial and procedural, rather than substantive. Both versions maintain the same intent: urging the federal government to take immediate action to prevent the spread of the New World screwworm into Texas. The core requests, to work with Mexico on mitigation efforts, expedite construction of a control facility, and fast-track approvals of relevant treatments and pesticides, remain identical.
