On July 4, 2025, authorities confirmed a second case of contagious nodular dermatitis (DNC) in Savoie, following an initial outbreak on June 29 in Entrelacs. This disease, affecting only cattle, zebu, and buffalo, is transmitted by insect bites and poses no threat to human health. In response, a 50 km restricted zone has been established around the outbreak site. This includes a 20 km protection zone, covering 50 communes, and a 50 km surveillance zone involving 150 communes.
The prefect of Savoie, Vanina Nicoli, has coordinated efforts through the departmental operational center to tackle the outbreak effectively. As part of immediate eradication measures, 52 infected cattle were culled on June 30, 2025. Santè publique France has classified DNC as a category A disease, which necessitates urgent control actions. Currently, four additional suspected cases are under investigation. To assist affected farmers, the Departmental Directorate of Employment, Work, Solidarity, and Population Protection (DDETSPP) has established a helpline for inquiries related to the outbreak.
