The Texas Animal Health Commission (TAHC), in collaboration with Texas A&M AgriLife Extension Service, is providing animal owners and producers, veterinarians, New World Screwworm (NWS) Certified Inspectors, and other stakeholders with a quick-reference resource outlining current animal movement requirements related to NWS. This platform contains content to facilitate TAHC-compliant movement of animals.
Access the platform through the TAHC NWS landing page or directly through this link: https://agalert.tamu.edu/nwsguide.
All livestock, equine, poultry, exotics of these species, and groups of rescue animals leaving a NWS-infested zone in Texas must meet current requirements prior to movement. These requirements vary by species, intended use of animal, type of movement, premises of origin, and destination. The NWS Movement Guidance resource is designed to simplify identifying the correct movement requirements for various situations.
As a general reminder, NWS Treatment/Movement Certificates must be issued by a responder deployed with the NWS response, a NWS Certified Inspector, or authorized veterinarian. NWS Certified Inspectors who have agreed to share their information are listed in a publicly available list on the TAHC NWS landing page.
The NWS Movement Guidance resource helps provide information conveniently, but the TAHC region office, local inspectors, and deployed responders are available to discuss more specific situations with producers. Additionally, each state may have different entry requirements related to NWS. Producers should work with their private veterinary practitioner for interstate movement; a certificate of veterinary inspection (CVI) must be issued. It is very important to always check with the destination state’s animal health office for their current entry requirements prior to movement.
