Executive Summary
Switzerland recorded more foodborne illnesses in 2025 than in the previous year. Campylobacteriosis was the most common infection with approximately 8,700 laboratory-confirmed cases, followed by salmonellosis (2,300 cases) and STEC infections (1,433 cases). Cantonal authorities reported 72 disease outbreaks to the federal government (2024: 43), which is mainly attributable to increased awareness and improved reporting rates. The Federal Council emphasizes the responsibility of food businesses, gastronomy, and consumers for food safety.

Clarus Lead
The stable but high infection numbers signal a structural challenge problem: while reporting rates have increased, constant case numbers suggest that existing hygiene requirements are insufficient. The Federal Council is responding with stricter limit values as of July 2026 for Listeria and has already increased requirements for Salmonella and Campylobacter. These measures aim to shift responsibility to businesses while activating consumers to take preventive measures – an approach that acknowledges the limits of state control.
Detailed Summary
The federal zoonosis report documents that the three most common foodborne infections are typically transmitted through animal-based food products and lead to gastrointestinal illnesses. Case numbers have remained at a constant, high level for several years – a sign that infection dynamics persist despite existing regulations.
The increased number of reported outbreaks (from 43 to 72) is not interpreted by the BLV as a deterioration in food safety, but rather as a result of improved reporting discipline by cantonal control authorities. This underscores the importance of transparency and data collection for evidence-based regulation. In recent years, the BLV has tightened limit values for Salmonella and Campylobacter in production; as of July 1, 2026, stricter requirements also apply to Listeria. Food businesses have a legal obligation for self-monitoring and must initiate recalls if products pose health risks.
Gastronomy is particularly held responsible for preventing cross-contamination – a common risk where pathogens transfer from raw to processed foods via utensils or gloves. Consumers are reminded of key hygiene rules: thorough hand hygiene, separation of raw and processed foods, complete cooking of meat, and cleaning of work surfaces after handling raw products.
Key Messages
- Campylobacteriosis dominates foodborne infections with 8,700 cases; numbers remain stable at high levels
- Rising outbreak reports (72 vs. 43) reflect better data collection, not fundamental deterioration
- Federal Council tightens limit values as of July 2026 for Listeria; earlier tightening for Salmonella and Campylobacter already implemented
- Responsibility is distributed among businesses (hygiene, self-monitoring, recalls), gastronomy (cross-contamination prevention), and consumers (kitchen hygiene)
Critical Questions
Evidence/Data Quality: What delay exists between infection event and reporting to the federal government, and how might this distort outbreak numbers?
Conflicts of Interest: Do food businesses have financial incentives to report or conceal contaminations, and how is this addressed regulatorily?
Causality: Can the stable case number despite tightened limit values be attributed to time lag effects of limit value adjustments, or do they indicate compliance deficits?
Feasibility: How is compliance with self-monitoring obligations verified for smaller and medium-sized gastronomy businesses, and what resources are available to cantonal authorities?
Side Effects: Could overly strict limit values lead to food waste or cost increases that are passed on to consumers?
Alternative Hypotheses: Could climatic factors or changed consumption patterns (e.g., more raw food) better explain the stable case numbers than hygiene deficiencies?
