Overview
- Public health agencies report 207 laboratory‑confirmed Salmonella Enteritidis infections, one death and a roughly 38% hospitalisation rate in the cluster recorded between 11 August 2025 and 1 August 2026.
- Genomic analysis ties the cases to a single strain (t5.9411) that appears related to a 2025 outbreak, strengthening the view of a common, sustained contamination source.
- Investigations by the UKHSA, FSA and APHA have identified links to eggs imported from outside the UK, mainly used by restaurants and catering, while finding no evidence so far that UK‑produced British Lion or Laid in Britain eggs are affected.
- Officials are conducting traceback and targeted inspections of food businesses after local probes found many exposures occurred after eating out, and they advise thorough cooking, careful hygiene and that vulnerable people only eat eggs with recognised assurance marks.
- The outbreak has renewed industry calls for imported egg standards to match UK controls and experts warn confirmed cases are likely the tip of the iceberg, meaning more infections or regulatory actions could follow as investigations continue.
