Contagious Bovine Nodular Dermatosis (CBND), known in France as dermatose nodulaire contagieuse bovine (DNCB), has led to significant health and agricultural concerns in the Isère department. As of July 7, 2025, an outbreak has prompted local authorities to establish rigorous containment measures affecting 117 municipalities. The disease, transmitted by insect bites, primarily impacts cattle and is classified as a Category A disease requiring immediate eradication efforts.
To mitigate the outbreak's spread, a regulated zone spanning 50 kilometers has been instituted around the affected area, impacting not just Isère but also the neighboring departments of Ain, Savoie, and Haute-Savoie. Specific biosecurity measures have been enforced, which include limitations on animal movements and enhanced sanitary surveillance.
"Farmers are urged to report any suspected cases of DNCB immediately," emphasized officials from the Departmental Directorate for Protection of Populations (DDPP). In response to the outbreak, the Agricultural Defense Group (GDS) of Isère is organizing informational meetings aimed at supporting farmers in adhering to the necessary guidelines. Immediate action is deemed crucial to protect the health of the livestock population and mitigate potential economic losses incited by the disease.
