Texas agriculture officials are expanding efforts to contain an outbreak of the New World Screwworm as confirmed cases continue increasing in the state. Texas state animal health authorities confirmed 11 cases involving cattle and other livestock, prompting expanded quarantine zones in affected areas. Under the restrictions, livestock cannot leave quarantine zones without authorization. The total number of cases is up to 12, including the confirmed case in New Mexico. News Nation Now said the growing number of cases has raised concerns among ranchers that the parasitic fly could spread farther north into major cattle-producing regions. Producers say the outbreak is especially troubling as confirmed cases move closer to the Dallas area. Officials are urging producers everywhere to closely monitor animals for signs of infestation and report suspected cases immediately. A Texas rancher told local media, "It's unsettling to see the outbreak moving closer. We're all paying close attention and hoping containment efforts work."
