New World screwworm response: U.S. Agriculture Secretary Brooke Rollins visited a Texas ranch after new detections of the flesh-eating parasite, warning it could devastate cattle and urging ranchers to watch wounds and treat fast. The USDA is preparing a major response as warming weather helps the pest spread. Pet treatment updates: The FDA granted emergency use authorization for generic nitenpyram tablets to treat screwworm in dogs and cats (at least 2 pounds and 4 weeks old), with vets possibly needing to remove remaining larvae. Florida containment: Florida issued an emergency rule blocking rescue and shelter dogs and cats from Texas and New Mexico to slow spread. Colorado River pressure: Arizona lawmakers added $6 million to a legal fund as states remain deadlocked; without a deal, Interior could impose a plan that could mean steep cuts for Arizona. Forest health: New Mexico’s tree deaths tripled in 2025 amid drought and heat, with beetle-killed conifer forest surging. Public health: New Mexico confirmed its first human plague case of 2026, prompting contact tracing and a local environmental check.
