Less than a month before New World screwworm was confirmed<\/a> in Texas for the first time in decades, state lawmakers heard warnings that an infestation of the flesh-eating parasite posed a growing threat to the state’s livestock industry, wildlife populations and economy.<\/p>\n

\n“Screwworm is a serious concern for [the U.S. Department of Agriculture], our state partners, and our livestock producers because of the damage and disruption it would cause to the U.S. livestock industry if not quickly identified and treated,” said Dudley Hoskins, the USDA’s undersecretary for marketing and regulatory programs.<\/p>\n

\nThe warning was one of many presented to legislators during a May 11 hearing of the Texas Senate Committee on Water, Agriculture, and Rural Affairs. In the meeting, agriculture officials and industry experts discussed the parasite’s steady march north<\/a> through Mexico \u2014 and the destructive effects its arrival in Texas could bring.<\/p>\n

Just weeks later, on June 3, the U.S. Department of Agriculture confirmed New World screwworm<\/a> in a calf in Zavala County. This marked the first U.S. case since the pest was eradicated from the country in the 1960s. In the days that followed, four more cases<\/a> were confirmed in Texas. A fifth case<\/a> was confirmed by the USDA on Tuesday.<\/p>\n

\nMay’s committee hearing offered a glimpse into how lawmakers and state officials viewed the threat before the first Texas cases were detected, along with how they planned to respond if the parasite reached the state.<\/p>\n

Confidence in the face of a billion-dollar threat<\/p>\n

\nNew World screwworm larvae feed on the living tissue<\/a> of warm-blooded animals, including livestock, wildlife and pets<\/a>. Officials have stressed that the parasite doesn’t threaten the safety of the U.S. food supply, but it could disrupt food production by harming livestock.<\/p>\n

\nThroughout the hearing, several Texas officials expressed confidence that the state was prepared to respond if \u2014 or when \u2014 screwworm reached Texas.<\/p>\n

\nTexas Parks and Wildlife Department Executive Director David Yoskowitz told the Senate panel that his agency was in regular contact with the U.S. Department of Agriculture, along with neighboring state agencies, about the growing screwworm threat.<\/p>\n

\nThis confidence was echoed by State Veterinarian Bud Dinges, who also serves as the executive director of the Texas Animal Health Commission. He said TAHC was “prepared to facilitate an effective and efficient New World screwworm response at a moment’s notice.”<\/p>\n

\nEven as officials expressed faith in the state’s preparedness, Phillip Kaufman, head of the Department of Entomology at Texas A&M University, warned the New World screwworm’s arrival could carry a steep economic cost. He estimated a major infestation could cost Texas’ cattle industry and the broader state economy $1.8 billion.<\/p>\n

\nThe figure includes losses from reduced livestock production, increased veterinary care, additional labor for inspections and treatment, and higher spending on medications and insecticides, according to Kaufman. He also noted the estimate doesn’t account for the state’s wildlife industry, which contributes more than $10 billion annually to the Texas economy.<\/p>\n

\nAt the time, Kaufman said he was “cautiously optimistic.”<\/p>\n

\n“We have the ability to manage this pest,” he said. “We will survive, and we are going to get rid of this fly again.”<\/p>\n

\nThe potential economic impact drew concern from several state lawmakers, including Republican Sen. Adam Hinojosa<\/a> of Corpus Christi, whose district includes much of South Texas.<\/p>\n

\n“From a state perspective, being that we are the front lines in how much economic devastation could occur in our state, I think we really should be looking at a Texas-state response,” Hinojosa said.<\/p>\n

New World screwworm larva will hatch and feed on the flesh of living animals, typically cattle.<\/p>\n

Production sterile flies to fight screwworm<\/p>\n

\nSince the first case was confirmed in South Texas, state and federal officials<\/a> have established quarantine zones<\/a> and increased surveillance and trapping efforts.<\/p>\n

\nBut a key part of the response involves releasing sterile male flies<\/a> into the environment. When wild females mate with those flies, their eggs do not hatch. Since female screwworms only mate once during their lifecycle, this causes the screwworm population to decline over time.<\/p>\n

\nAs of now, roughly 4 million sterile screwworm flies are already being released each week by air in areas near the U.S.-Mexico border, according to federal officials<\/a>.<\/p>\n

\nAfter lawmakers questioned whether enough flies would be available to contain an outbreak, Undersecretary Hoskins with the USDA outlined plans to dramatically expand production.<\/p>\n

\nThese plans include a new sterile fly production facility<\/a> at Moore Air Base in South Texas. The new facility is expected to produce up to 100 million sterile flies per week when it opens in November 2027, with capacity increasing to as many as 300 million flies per week by the end of 2028, according to Hoskins.<\/p>\n

\nHowever, that timeline could be accelerated. As part of his expanded disaster declaration issued Friday<\/a>, Gov. Greg Abbott directed state agencies to expedite construction of the facility in hopes of bringing it online before summer 2027.<\/p>\n

Preparing for a long fight<\/p>\n

\nDuring last month’s hearing, Hoskins told the Texas Senate panel that USDA is investing $21 million to convert an existing fruit fly facility in Metapa, Mexico, into a sterile screwworm fly production hub<\/a>. Once complete, the facility is expected to produce an additional 60 million to 100 million sterile flies per week, with production potentially beginning as early as summer 2026.<\/p>\n

\nHoskins also highlighted emerging technologies under development, including NovoFly<\/a>, a gene-edited fly designed to produce more sterile male offspring. The technology is still under development, but Hoskins said USDA is working with the U.S. Environmental Protection Agency to evaluate its potential use in future screwworm control efforts.<\/p>\n

\n“Bringing that technology on expeditiously will give us more flies,” Hoskins said.<\/p>\n

\nWhile state and federal officials say the current infestation remains limited, Kaufman with Texas A&M warned lawmakers that the fight against screwworm is unlikely to end anytime soon.<\/p>\n

\n“We are in this battle for \u2014 my prediction is \u2014 decades,” Kaufman said.\n<\/p>\n
