Three animal cases remain active, and officials have also recorded one wild fly detection.<br \/><em>Last updated: Sunday, Oct. 4, 2026 7:00 p.m<\/em><br \/>There have now been 53 confirmed New World screwworm animal cases in the United States since June, including 51 in Texas and two in New Mexico.<br \/>The latest case was confirmed Oct. 2 in a dog in Brewster County, Texas. It is one of three animal cases currently considered active.<br \/>The other active cases are goats in Crockett County, Texas, confirmed Sept. 26, and a horse in Grant County, New Mexico, confirmed Sept. 17.<br \/>A horse in Presidio County, Texas, confirmed Sept. 9 and previously listed as active, is now considered inactive.<br \/>Officials have also recorded one wild screwworm fly detection during the current U.S. outbreak. The fly was found in a surveillance trap in Brewster County on Sept. 25. Fly trap detections are tracked separately and are not included in the 53 animal cases.<br \/>Of the 53 animal cases recorded since the first U.S. case was confirmed June 3, 52 have involved domestic animals. No cases have been confirmed in wildlife or feral animals.<br \/>Federal officials have said the parasite&#8217;s northward spread has slowed, though the threat remains.<br \/>The USDA says it has released more than 1 billion sterile flies in Texas since February and is aiming to increase production to 500 million flies a week by next summer.<br \/>Agriculture Secretary Brooke Rollins has said officials are making progress in containing the outbreak but have warned that the threat has not passed, particularly in Arizona and New Mexico.<br \/><iframe title=\"tpr-usda-screwworm-dashboard.vercel.app embed\" loading=\"lazy\" style=\"border: none; border-radius: 7px;\" src=\"https:\/\/tpr-usda-screwworm-dashboard.vercel.app\/\" name=\"myiFrame\" width=\"100%\" height=\"600px\" scrolling=\"no\" sandbox=\"allow-scripts allow-same-origin allow-forms\" allowfullscreen=\"allowfullscreen\"><\/iframe><br \/>Despite its name, the New World screwworm isn&#8217;t a worm. It is the larval stage of the fly (Cochliomyia hominivorax), a parasite that feeds on the living tissue of warm-blooded animals.<br \/>Infestations begin when an adult female screwworm fly lays eggs in an open wound or natural body opening. Within hours, the eggs hatch and the larvae begin feeding on living tissue, unlike common maggots, which feed on dead or decaying tissue.<br \/>As the larvae burrow deeper into tissue, wounds become larger and often infected. Without treatment, infestations can be fatal.<br \/>The screwworm primarily threatens livestock and wildlife, making it a major concern for Texas ranchers and animal health officials.<br \/>Animals at risk include:<br \/>Human infestations are rare. Most occur when untreated wounds are exposed in areas where the fly is circulating. The current outbreak primarily affects livestock, wildlife and pets.<br \/>According to the U.S. Department of Agriculture, New World screwworm is not considered a food safety threat. The parasite feeds on living tissue in open wounds \u2014 not meat intended for consumers \u2014 and animal health and inspection systems are designed to keep infested animals out of the food supply.<br \/>Early detection is critical. Animals infected with screwworm may show:<br \/>Veterinarians recommend inspecting animals regularly after injuries, surgical procedures, branding or any condition that creates an open wound.<br \/>Texas has one of the largest livestock industries in the United States, along with extensive ranchland and abundant wildlife populations, particularly white-tailed deer. That combination makes the state especially vulnerable if screwworm becomes reestablished.<br \/>A widespread outbreak could lead to:<br \/>The Texas Animal Health Commission and the U.S. Department of Agriculture have expanded surveillance, increased monitoring of animal movement and encouraged rapid reporting of suspected infestations.<br \/>The United States eliminated screwworm using one of the most successful pest control programs in history: the sterile insect technique.<br \/>Scientists bred and released millions of sterile male flies. Because female screwworm flies typically mate only once, breeding with a sterile male produces no offspring, gradually collapsing the wild population.<br \/>That strategy eradicated screwworm from the United States and much of North America. However, the parasite remains present in parts of Central and South America, meaning the risk of reintroduction never fully disappears.<br \/>For most Texans, there is no reason to change their daily activities. The greatest risk remains to livestock, pets and wildlife.<br \/>Animal owners should:<br \/>Hunters should also inspect harvested game for unusual wounds or signs of infestation and report suspected cases to wildlife officials.<br \/>If you suspect an infestation, contact your veterinarian immediately before transporting the animal.<br \/>For the latest information and guidance, visit:<br \/><a href=\"https:\/\/www.tpr.org\/environment\/2026-09-19\/how-livestock-smuggling-could-help-spread-new-world-screwworms\">The illegal movement of animals \u2014 particularly horses \u2014 could thwart the U.S. Department of Agriculture&#8217;s effort to stop the spread of the parasite.<\/a><br \/><a>Texas A&amp;M AgriLife livestock entomologist Sonja Swiger discusses the risks New World screwworm poses to pets, people and livestock, addresses concerns about the food supply and explains why reporting infestations is critical.<\/a><br \/><a href=\"https:\/\/www.tpr.org\/economy-and-labor\/2026-06-25\/screwworm-spread-across-texas-threatens-livestock-and-millions-of-wild-deer\">Wildlife experts warn that deer may be especially vulnerable because there is no proven way to treat them in the wild.<\/a><br \/><a>The New World screwworm has crossed into Texas from Mexico, threatening livestock, wildlife and pets.
