A new monitoring report for 2025, jointly published by the Federal Food Safety and Veterinary Office (FSVO) and the Federal Office of Public Health (FOPH), provides a comprehensive overview of zoonotic and foodborne diseases in Switzerland. While human cases for the most common zoonotic pathogens remained stable or rose slightly, authorities recorded a sharp, unprecedented spike in the number of reported foodborne illness outbreaks.
- Campylobacteriosis: Closely linked to poultry meat handling and consumption, Campylobacteriosis was once again the most frequently reported zoonosis in humans. In 2025, a total of 8,654 laboratory-confirmed cases were reported, a slight increase over the 8,269 cases from the previous year. Case numbers have remained consistently high over the past decade.
- Salmonellosis: This infection remained Switzerland's second most frequently reported zoonotic disease, with 2,280 laboratory-confirmed human cases in 2025 (compared to 2,257 the previous year). This figures sits above the average for the past decade. Alongside the expanded use of rapid multiplex PCR testing, experts note that rising egg consumption among the Swiss population in recent years is a potential contributing factor to this sustained trend.
The most striking finding in the report is the sudden increase in foodborne outbreaks reported by Swiss authorities. While the country averaged a stable 37 to 43 outbreaks per year since 2021, the number sharply rose to 72 recorded outbreaks in 2025. These outbreaks affected at least 660 people, resulting in 21 hospitalizations and two deaths. Officials emphasize that this surge does not necessarily indicate worsening food safety standards across Switzerland, but rather a significant improvement in public and institutional awareness and reporting.
