As of July 5, 2025, France is addressing an outbreak of Contagious Nodular Dermatitis (DNC) following confirmed cases in Savoie. The first instance was reported on June 29 at a dairy farm in Entrelacs, followed by a second case identified on July 4. Immediate containment measures have been enacted to control the spread of this infectious disease among cattle.
On June 30, 2025, local authorities initiated the depopulation of 52 infected cattle as a part of their response, aiming to minimize the impact of the outbreak. The Prefect of Savoie, Vanina Nicoli, has activated the departmental operational center to coordinate the crisis response effectively. A comprehensive 50-kilometer regulated zone has been established, which includes a 20-kilometer protection zone incorporating 50 communes, and a 50-kilometer surveillance zone covering additional areas in Savoie, Haute-Savoie, Ain, and Isère.
DNC, transmitted by vectors such as mosquitoes, primarily affects bovines and is classified as a category A disease by the EU, necessitating rigorous eradication protocols, including movement restrictions and the culling of affected herds. Currently, veterinary teams are investigating four additional suspected cases in the region to prevent further spread. To facilitate communication during this crisis, the Departmental Directorate of Employment, Labor, Solidarity, and Protection of Populations has established a dedicated phone line for farmers to address their concerns.
The Prefect has highlighted the critical need for collaboration between agricultural stakeholders to contain DNC and safeguard unaffected herds, stressing cooperation as vital in managing the situation. Authorities continue to monitor the outbreak closely and will adapt their response as new information becomes available.
