We promptly addressed an isolated case of screwworm in Montemorelos, Nuevo León
The risk of GBG establishing itself in Nuevo León is minimal.
National Service for Agrifood Health, Safety and Quality | December 1, 2025
The case involves a livestock movement, so the infestation occurred before the cattle arrived in Nuevo León.
Senasica reports that, as a result of a notification made by veterinary medical personnel from an authorized feedlot in Montemorelos, Nuevo León, a case of myiasis caused by the cattle screwworm (GBG) in a female bovine from southern Veracruz was promptly addressed.
The emergency protocol for handling cases in the disease-free zone was immediately activated, with official personnel inspecting the affected area, collecting samples for remote diagnosis, and administering the appropriate treatments. No other affected animals were identified, confirming that this is an isolated case that was promptly contained.
Based on the technical analysis carried out by specialists from Senasica, it is concluded that:- The case corresponds to a mobilization, so the infestation occurred before the arrival of the cattle in Nuevo León.
- The area maintains an active sterile fly release polygon, which acts as a biological barrier that inhibits insect reproduction.
- Immediate actions such as cleaning, larvicidal treatment, spray baths, and thorough inspection of the lot minimized any possibility of dissemination.
- The current climatic conditions of Montemorelos (temperatures between 11 and 20°C and altitude close to 500 meters above sea level) are not conducive to the survival and reproduction of the insect.
- Based on these elements, Senasica determines that the risk of GBG establishment in Nuevo León is minimal and that the epidemiological situation is under control
