Key Points

  • • Seven DNC outbreaks reported in Savoie, primarily in Entrelacs.

An outbreak of Contagious Nodular Dermatitis (DNC) has emerged in the bovine population of Savoie, France, prompting immediate actions from local authorities. As of July 16, 2025, seven outbreaks have been reported, most notably concentrated in Entrelacs, leading to the culling of 143 infected bovines since the crisis began. The disease, which affects only cattle, zebu, and buffalo, is vector-borne and poses no threat to human health.

The prefect of Savoie, Vanina Nicoli, highlighted the urgency of eradicating DNC to protect the livestock sector. Biosecurity measures are being strictly enforced, including movement restrictions and enhanced veterinary surveillance across affected areas. The regulated zones for monitoring have expanded to involve 246 municipalities, and ongoing investigations are being conducted across farms to identify potential risks.

Farmers are being provided with vital resources, including a dedicated hotline for DNC inquiries and support from the Réagir network, ensuring they can manage agricultural difficulties effectively. Authorities stress the importance of these measures, especially since even asymptomatic cattle can transmit the disease through biting insects. The proactive approach aims to contain the outbreak and safeguard unaffected herds in the region.
