Overview
- The case involved a female bovine that arrived in Montemorelos from southern Veracruz, prompting immediate inspection, telediagnostic sampling and treatment under emergency protocols.
- SENASICA reported no additional affected animals, determining the incident to be isolated and promptly contained.
- A technical review concluded the infestation occurred before the animal entered Nuevo León, aligning with this year’s detections linked to livestock movements from southern and central regions.
- Preventive actions include an active sterile-fly release polygon, cleaning, larvicide application, spray baths, exhaustive lot inspection and active searches within a 20‑kilometer radius.
- The federal animal-health service temporarily suspended cattle movements from affected zones into Nuevo León during the investigation, and current local temperatures and altitude are considered unfavorable for the pest.
