Description
Sebastian von Schreeb and co-authors trace a Salmonella outbreak in Portugal in a 2026 report covering spring 2024. Cases spread across two regions, and the team needed to find the food source fast.
Gene sequencing grouped the outbreak cases into one tight cluster. The team compared those cases with cases from the prior year in a case-case design. Fresh cheese stood out, with far higher odds among cluster cases. A site visit found hygiene faults at the cheese plant, and steps were enforced. Product tests came back clean, but the full picture still pointed to fresh cheese. The report shows how gene data sharpen food outbreak hunts.
