Over 160 individuals across nine European countries contracted Salmonella between July and September 2026. This recent spike is part of a broader trend, with 800 confirmed infections reported internationally since January 2023.
Why it matters
The persistence of this outbreak since 2023 highlights the ongoing challenge of identifying and remediating contamination sources in agricultural supply chains. Local authorities in Italy have moved to restrict fresh produce in institutional settings to limit further exposure.
Official surveillance has tracked 800 confirmed Salmonella infections since January 2023, including 160 recent cases reported in nine European countries. The investigation remains ongoing as authorities continue to evaluate potential environmental contamination sources.
The players
Puglia
An Italian region that suspended the use of raw fresh tomatoes in institutional canteens.
The details
Testing in Italy identified Salmonella Strathcona and monophasic Salmonella Typhimurium in cherry tomatoes. The pathogen was also discovered in well irrigation water, suggesting a pathway for widespread crop contamination. In response, Italian authorities in the Puglia region prohibited the use of raw, fresh tomatoes in institutional catering facilities like hospitals and schools.
Timeline
January 2023 - September 2026: 800 total Salmonella infections were reported.
November 2024: The outbreak strain was found in Italian irrigation water.
June 2026: Germany recorded 39 cases linked to the outbreak.
July - September 2026: More than 160 new infections occurred across nine European countries.
Health Landscape
This outbreak follows a pattern set by the 2018 Cyclospora outbreak linked to McDonald's salads, highlighting the difficulty of trace-back efforts in produce-related foodborne illnesses. The ongoing nature of these cases reflects the complex challenges in maintaining food safety standards across international agricultural supply chains.
While investigation is ongoing, individuals should remain aware of potential foodborne illness symptoms like fever or diarrhea. If you suspect an illness after eating fresh produce, contact your doctor to discuss whether testing or clinical evaluation is appropriate.
The takeaway
Public health authorities expect new outbreaks to occur in upcoming seasons until the primary contamination source is fully addressed. If you are concerned about food safety, track any unusual symptoms and discuss persistent digestive issues with your physician.
