Unlike most maggots, which feed on dead or decaying material, New World screwworm larvae burrow into healthy tissue and enlarge wounds as they feed. This condition is called myiasis and can become severe or life-threatening if not detected and treated quickly.<\/p>\n New World screwworm can infest livestock, horses, pets, wildlife, birds, and, rarely, people. In livestock, infestations can cause animal suffering, weight loss, reduced production, secondary infections, death, veterinary costs, labor costs, animal movement restrictions, and trade impacts.<\/p>\n The United States eradicated self-sustaining New World screwworm populations in the 1960s through the sterile insect technique. However, the pest has re-emerged and moved northward through Central America and Mexico in recent years. USDA APHIS confirmed New World screwworm in a calf in Zavala County, Texas, on June 3, 2026. Because the situation is changing quickly, livestock producers, veterinarians, animal owners, wildlife professionals, and public health partners should rely on current state and federal guidance.<\/p>\n For the most current information, see USDA\u2019s Screwworm.gov response hub<\/a> and the Colorado Department of Agriculture New World Screwworm page<\/a>.<\/strong><\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.24.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/agsci.colostate.edu\/agbio\/wp-content\/uploads\/sites\/127\/2026\/06\/closeup-of-NWS-fly-and-egg-mass-on-wound.jpg” alt=”Metallic blue-green New World screwworm fly” title_text=”closeup of NWS fly and egg mass on wound” _builder_version=”4.27.6″ _module_preset=”default” custom_margin=”||-1px||false|false” custom_padding=”||||false|false” border_width_top=”4px” border_color_top=”#F15625″ global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_line_height=”1.4em” custom_padding=”5px||||false|false” global_colors_info=”{}”]<\/p>\n Closeup of New World screwworm fly and egg mass on a wound.
