Chihuahua state authorities detected the first case of screwworm in a calf near Hidalgo del Parral [1], [2].
The discovery of the parasite, known as gusano barrenador, triggers immediate containment efforts to prevent a wider outbreak across Mexico's livestock populations. Because the pest can cause severe tissue damage and death in animals, its presence threatens the regional agricultural economy and animal welfare.
Authorities responded by activating both state and federal contingency protocols [1], [2]. These measures are designed to isolate the infected animal and monitor the surrounding area to stop the pest from spreading to other herds.
According to reported data, the contamination expansion distance is currently monitored within a 20 kilometer radius [1]. Veterinary teams are working to identify any other affected livestock in the vicinity of Hidalgo del Parral to ensure the infestation remains localized.
State officials said the activation of these protocols is a necessary step to safeguard the state's cattle industry. The coordination between state and federal agencies aims to implement rapid eradication techniques, and strict movement controls for livestock in the affected zone [1], [2].

The detection of screwworm in Chihuahua represents a significant veterinary challenge. Because this parasite can rapidly devastate livestock and potentially affect wildlife, the 20 kilometer monitoring zone is a critical buffer. The success of the federal contingency protocols will determine whether this remains an isolated incident or evolves into a broader agricultural crisis for northern Mexico.
