Rep. Fletcher: The New World screwworm has been found in Texas. This flesh-eating parasite previously eradicated from the U.S. poses a huge threat to our cattle. Last March, the Trump administration fired more than 15,000 USDA employees and eliminated a program to contain the screwworm in Central America. The threat of New World screwworm is just one consequence of the Trump administration's reckless campaign to eliminate funding for government programs that Americans rely on.

The flesh-eating New World screwworm has been found in Texas, with the parasite infecting at least one animal – a 3-week-old calf, according to the USDA. The screwworm fly usually infests livestock and other warm-blooded animals – including, in rare cases, people – by laying its eggs in open wounds or orifices such as the eyes, ears, nose or mouth, which can then eat living tissue or flesh once they hatch, according to the CDC. CBS News' Jason Allen has more from Texas.

Rollins wants to blame Biden’s “open borders” for screwworm. Tiny problem: USDA and CDC describe this as an animal-health failure driven by livestock, pets, wildlife, surveillance, and sterile-fly capacity, not some magic parasite caravan. She also skips the budget history. Trump-era cuts weakened the USDA/international systems that help hold the screwworm line. Then Biden’s USDA put $109.8M into emergency control in 2023 and another $165M in 2024. So no, this wasn’t “nothing was done.” If you’re going to politicize flesh-eating parasites, at least have the decency not to edit out the damn funding trail.

More than 50 years ago, USDA scientists pioneered the sterile fly technique that eradicated New World screwworm from the United States. Today, we're putting that proven science back to work. We've partnered with Panama to expand sterile fly production, just opened a new sterile fly production facility in Mexico, and next year Moore Air Base in Texas will begin producing sterile flies here at home. We're using American innovation to protect our ranchers, our livestock, and eradicate New World screwworm once again. We're off to a strong start but there is much work ahead of us. 🇺🇸🇺🇸

🚨 Possible Flesh-Eating New World Screwworm Parasite Case Under Investigation in South Texas Federal officials are investigating a potential “outbreak” of the New World screwworm — a dangerous flesh-eating parasite that was eradicated from the U.S. in the 60’s— after samples from two calves in South Texas were sent to a federal laboratory for testing. Brooke Rollings, Sec of Agriculture doesn’t seem to worried about it… but the MSM is trying to hype it up.

THE FLESH-EATING FLY THREAT IS SPREADING Watch Full Episode: Lara Logan sits down with former U.S. Border Patrol agent and Texas Public Policy Foundation Senior Research Fellow Ammon Blair to examine the growing threat of the New World Screwworm. Once nearly eradicated from the United States, this flesh-eating parasite has returned, putting livestock, wildlife, pets, and even humans at risk. Blair explains how the parasite spreads, why warmer southern states are especially vulnerable, the staggering economic damage already being seen across the Americas, and how cartel-controlled cattle operations have drawn the attention of investigators tracking both organized crime and the spread of the screwworm. #LaraLogan #Screwworm #BorderSecurity #FoodSecurity #NationalSecurity

🚨SCREWWORM UNDER CONTROL🚨 USDA Secretary Brooke Rollins assures that they are using technology to contain the screwworm & eventually push it back South. Once eradicated in 1966, the screwworm has migrated from Mexico — in part — because of Joe Biden’s open borders policy. Gov’t is building a first-ever fly facility in America, which will release 10 million sterilized male screwworm flies per week to mate with the females. This sterilized fly technique also includes a first-ever ground release to complement the air release. “Keep your eyes on your livestock. Report, report, report. We have all the veterinarians on the ground — mobile testing units ready to go.” -Secretary Brooke Rollins

🚨FLESH-EATING PARASITE FOUND IN SOUTH TEXAS CALF🚨 Meet the New World screwworm fly. Eradicated since 1966 in the US, this parasitic fly lays eggs in fresh wounds of warm-blooded animals. The larvae feed on the host’s flesh, which — if left untreated — can cause the animal to die. While the screwworm fly is NOT contagious, it does threaten the cattle industry. It’s rare for humans to contract the parasite, but a Maryland man who traveled to El Salvador was diagnosed with this visitor in 2025. The US Department of Agriculture is releasing millions of sterilized screwworm flies into targeted areas because female flies only mate once. This method — called Sterile Insect Technique (SIT) — will help to stop the spread of the screwworm fly. Cattle ranchers should be on the lookout for rapidly growing, foul-smelling wounds that have white egg masses.

America’s food supply is safe, and the Dept. of Agriculture is taking swift, aggressive action to eradicate New World screwworm. This is a pest the United States successfully eradicated in the 1960s through coordinated science and sterile fly technology. Under the previous administration, New World screwworm began to re-emerge and move north through the Darien Gap as millions of people traveled towards the southern border. By 2023, screwworm was present in Mexico. It was shocking when I came into office in February of last year to learn the last administration had just five full-time staff working on screwworm. As of last Wednesday, when our first New World screwworm case was confirmed, USDA had over 100 staff working on preparedness and response—a team we built over the last 14 months in anticipation of this moment. This in addition to the $1.3 billion committed and invested for new infrastructure and sterile fly facilities, the first opening later this month. We have rapidly scaled up our response: expanding surveillance across high-risk corridors, strengthening coordination with state agriculture officials and international partners, and accelerating deployment of proven sterile fly operations that were used successfully to push this pest out of the United States in the 1960s and all the way to South America by the 1980s. We beat screwworm in the ’60s, and we will beat it again. Visit for more information and up to date information.🐄🇺🇸
