New online certification program aims to strengthen the state’s response against the destructive New World screwworm
Austin, Texas, 15 June 2026 – Texas is taking an innovative approach to protect its livestock industry from a dangerous pest that has raised concerns across the state. Officials have launched a free online training course designed to certify more New World screwworm inspectors, helping speed up detection efforts and maintain the safe movement of livestock.
The New World screwworm is not actually a worm but the larva of a parasitic fly. Unlike common fly larvae that feed on dead tissue, screwworm larvae attack living flesh, causing painful wounds and serious health problems in animals. Livestock, wildlife, pets, and, in rare cases, humans can be affected if infestations are not treated quickly.
As cases of the pest have been detected in parts of Texas, state leaders are working to expand the number of trained professionals who can identify and respond to potential outbreaks. The newly launched online program was developed through a partnership involving Texas A&M AgriLife Extension, the Texas Animal Health Commission, and federal animal health agencies. The goal is to make inspector training more accessible and ensure faster responses when suspicious cases are reported.
The course is available online and includes educational modules covering the screwworm’s life cycle, methods of detection, reporting procedures, treatment practices, and livestock movement requirements. Participants can complete the training remotely, making it easier for professionals across Texas to gain the knowledge needed to assist in monitoring and prevention efforts.
Several groups are eligible to pursue certification through the program, including veterinarians, veterinary technicians, agriculture inspectors, animal control officers, livestock deputies, and other professionals involved in animal health and agriculture. The initiative significantly expands the state’s inspection capacity at a time when rapid action is considered essential.
Beyond professional certification, the course is also open to members of the public who want to learn more about protecting animals from pests. Officials hope greater awareness will encourage livestock owners and ranchers to recognize warning signs early and report suspected cases before infestations spread.
The threat posed by the New World screwworm extends beyond individual animals. Experts warn that widespread infestations could disrupt livestock operations, impact agricultural productivity, and create significant economic challenges for ranchers. Because Texas is one of the largest cattle-producing regions in the United States, protecting herds remains a top priority.
To combat the pest, authorities continue to use proven control methods, including the release of sterile male flies. This technique reduces reproduction rates and has historically played a major role in eliminating screwworm populations. Combined with increased surveillance and public education, officials believe the strategy can help limit the pest’s spread and protect animal health.
Animal owners are being encouraged to routinely inspect livestock and pets for unusual wounds, signs of irritation, or evidence of larvae. Early detection remains one of the most effective tools for preventing larger outbreaks and reducing the impact on affected animals.
The launch of the online certification course reflects a growing trend in agricultural management, where digital education is being used to address real-world challenges quickly and efficiently. By expanding access to training and strengthening its network of inspectors, Texas is aiming to stay ahead of a pest that has the potential to threaten both animal welfare and the livestock economy.
