The Federal Food Safety and Veterinary Office (FSVO) has reported a higher number of food-borne illnesses in Switzerland in 2025 than in 2024, based on its latest report on the monitoring of zoonoses and food-borne disease outbreaks. Campylobacteriosis remained the most common food-borne illness, with around 8,700 laboratory-confirmed cases, followed by salmonellosis with around 2,300 cases and infections with Shiga toxin-producing Escherichia coli (STEC) with 1,433 cases. All three are usually transmitted via food of animal origin and cause gastrointestinal illness; case numbers have remained relatively stable over several years, though at a high level.

The cantonal food control authorities additionally reported 72 food-borne disease outbreaks to the Confederation in 2025, up from 43 in 2024. According to the FSVO, this increase does not indicate a fundamental deterioration in food safety, but is attributable primarily to heightened awareness leading cantonal authorities to report outbreaks more consistently. The FSVO recalled that food and slaughter establishments must comply with the applicable hygiene requirements, including limit values for Listeria, Salmonella, and other pathogens that are adjusted regularly in light of new findings, with stricter limit values for Listeria applying from 1 July 2026, and recommended that consumers protect themselves through good kitchen hygiene.
