Outbreak Overview
Public-health agencies are investigating three genetically related clusters of *Salmonella Enteritidis* that together have infected 474 people and caused two deaths. All clusters are associated with consumption of eggs in cafés, restaurants and takeaway outlets rather than home-cooked meals. Sample dates for the infections span from 11 August 2025 to 8 August 2026. The largest cluster (strain t5.9411) accounts for 259 confirmed cases and one death; the second (t0.24068) adds 177 cases with no fatalities; the third (t5.9765) contributes 38 cases and one death. Hospitalisation has been reported for dozens of patients, and ages range from under one year to 92 years.
Data & Statistics
- t5.9411 cluster – 259 cases, 1 death (samples 11 August 2025 – 8 August 2026).
- t0.24068 cluster – 177 cases, 0 deaths (samples 27 May 2025 – 5 August 2026).
- t5.9765 cluster – 38 cases, 1 death (samples 27 January 2026 – 29 July 2026).
- Total – 474 cases, 2 deaths across England, Scotland, Wales and Northern Ireland.
- Hospital admissions: 41 in the first cluster, 12 in the second, 5 in the third (?34 hospitalisations overall).
- Median ages: 30 years (first cluster), 29 years (second), 32 years (third).
Background & Context
The United Kingdom imports roughly 1.6 billion eggs annually, a volume that has risen 60 % since 2021, according to the British Egg Industry Council. Imported eggs are commonly used in bulk for catering, making it difficult to trace a single source when a food-borne pathogen spreads. Previous UK salmonella outbreaks have been linked to eggs from European producers such as Poland, but the current strain’s origin remains unidentified.
Official Statements & Responses
- Professor Paul Wigley, professor of animal microbial ecosystems at the University of Bristol, warned that bulk-imported eggs are cheaper than “lion-mark” eggs and may be mixed across batches, increasing the difficulty of pinpointing a source.
- Professor Brad Spiller, head of medical microbiology at Cardiff University, called the common-source nature of the outbreak “the most concerning aspect” of the situation.
Conflicting Reports & Gaps
Sources differ on the total case count because some reports focus only on the first cluster (259 cases) while others aggregate all three clusters (474 cases). The specific country of origin for the contaminated eggs has not been confirmed, and investigations continue to assess whether additional food items might be involved. No evidence links the outbreaks to domestically produced eggs, but the precise supply chain pathways remain unclear.
Verbatim Quotes
- “It is of concern to have an outbreak of this size. There are thousands of salmonella cases each year, but rarely are they on this scale where hundreds of people are being infected by a common strain.” — Prof Mark Stevens, the chair of microbial pathogenesis at the University of Edinburgh
- “Similarly, if any fresh fruit or vegetables have come into contact with the bacteria, they can also present a risk to you.” — Ian Budd, lead prescribing pharmacist at Chemist4U
