The UK Health Security Agency (UKHSA) is investigating a salmonella outbreak that has been linked to imported eggs, after one person died and 207 people fell ill over the past year, most of them in recent weeks. Hospitality businesses that serve eggs, particularly in dishes that are raw, lightly cooked or hold eggs at room temperature, should treat this as a prompt to check their supply chain and kitchen practices now, not wait for further guidance.
What Has Happened
According to BBC News and UKHSA’s Health Protection Report (13 August 2026), 207 cases of the outbreak strain, Salmonella Enteritidis, have been confirmed between August 2025 and August 2026, with 206 of them in 2026 alone. 38% of cases needed hospital care, two people developed serious blood poisoning (septicaemia), and one person died. Those affected range from babies to people in their nineties. UKHSA also notes this outbreak is phylogenetically linked to a separate outbreak in 2025 that was also associated with imported eggs, which points to an ongoing supply-chain risk rather than a single, one-off contamination event.
- 199 of the 207 cases have been in England, including 47 in London and 38 in Yorkshire and Humber
- Six cases have been recorded in Scotland, one in Wales and one in Northern Ireland
- Of 114 cases interviewed, 95 (83%) reported eating food prepared outside the home before becoming ill
- 24 cases have been linked to five food businesses, with 11 of those cases involving egg-based dishes specifically
- Investigators have found eggs from multiple sources, including egg importers, but say there is currently no identified link to UK-produced eggs or poultry
Hannah Charles, lead epidemiologist for gastrointestinal infections at UKHSA, said the agency is "working with Food Standards Agency and other public health agencies to investigate a salmonella outbreak that may be linked to eggs imported from outside of the UK." The FSA has been liaising directly with local Environmental Health teams, providing food businesses with advice on food safety management where issues have emerged. Investigations into the exact source are ongoing, and UKHSA has said it is likely there will be further cases, including some people who became unwell but did not report it. The risk to the general public is described as low.
Why This Matters for Your Business
Most cases in this outbreak followed eating out, not eating at home, which puts the spotlight squarely on food businesses. If your kitchen uses eggs in dishes served raw, lightly cooked or briefly cooked, such as mayonnaise, hollandaise, mousse, tiramisu, soft-boiled or poached eggs, this outbreak is directly relevant to your risk profile. It is also a reminder that a hazard can enter your kitchen through a supplier you trust, which is exactly the kind of risk a HACCP plan is designed to control at goods-in, not just at the pass.
What the Officials Are Advising
Jacquelyn McCormick, Head of Incidents at the Food Standards Agency (FSA), said eggs that are thoroughly cooked and handled hygienically should not present a food safety risk. Her advice, as reported, is that infants, young children, pregnant people and older adults should only eat runny or raw eggs if they carry the British Lion mark or are produced under the Laid in Britain egg assurance scheme. She also advised that anyone handling eggs, eggshells or egg packaging should wash their hands thoroughly with soap and water afterwards.
Nick Allen, chief executive of the British Egg Industry Council, pointed out that UK hens are subject to mandatory salmonella vaccination, while "increasing volumes of imports" produced under "less stringent regulations" continue to arrive in Britain. Dr Kathleen O’Reilly of the London School of Hygiene and Tropical Medicine recommends that diners check a venue’s Food Hygiene Rating when deciding where to eat, which is a good reminder that your published FHRS score is doing quiet marketing work for you every day.
Six Things to Check in Your Kitchen This Week
- Trace your egg supply: confirm with every supplier whether the eggs you buy are UK-produced, carry the British Lion mark, or come from the Laid in Britain scheme. If you cannot get a clear answer, treat that as a red flag worth acting on.
- Review raw and lightly cooked egg dishes: mayonnaise, hollandaise, soft-boiled eggs, mousse, tiramisu and similar items carry the highest risk. Consider pasteurised egg products for these dishes, particularly if you serve vulnerable groups.
- Flag vulnerable customers: if you cater for care homes, nurseries, schools or hospitals, apply the FSA’s stricter advice: only serve runny or raw eggs with British Lion or Laid in Britain assurance to infants, young children, pregnant people and older adults.
- Tighten handwashing after handling eggs: shells and packaging can carry salmonella even when the egg itself looks clean. Handwashing after cracking, sorting or disposing of eggs and boxes should be a named step in your routine, not assumed.
- Update your HACCP plan: add or review the control point for egg-containing dishes, including minimum core cooking temperature and supplier verification checks, so the plan reflects a named, current hazard rather than a generic one.
- Check your traceability records: if a supplier or batch is later implicated, you need to show, quickly, which deliveries went where. Goods-in records and batch codes are what make a recall manageable instead of a guessing game.
If a Customer Reports a Suspected Illness
Take any report seriously, record it in writing with dates, dishes and symptoms, and contact your local Environmental Health team if you suspect a link to food served on your premises. Acting early and keeping clear records protects your customers and puts you in the strongest possible position if UKHSA or the FSA ever need to trace a case back through the supply chain.
How Kitchen Tonic Can Help
This is exactly the kind of live risk our HACCP and consulting work is built for: reviewing your supplier due diligence, tightening control points for high-risk ingredients, and making sure your paperwork would hold up if an EHO asked about it tomorrow. If your team needs a refresher on safe egg handling and cross-contamination control, our Level 2 Food Safety in Catering course covers exactly this ground, and our training team can run it for your whole site. Our free HACCP checklist and EHO inspection preparation guide are a good starting point if you want to check your own paperwork first, and our free risk assessment takes ten minutes if you are not sure where your biggest gaps are.
Frequently Asked Questions
Is it safe to serve eggs right now?
Yes, according to the FSA, provided eggs are thoroughly cooked and handled hygienically. The specific caution is around raw or runny eggs, which the FSA says should only be given to infants, young children, pregnant people and older adults if they carry the British Lion mark or are produced under the Laid in Britain scheme.
What does the British Lion mark actually guarantee?
It signals that the egg comes from a UK flock vaccinated against salmonella under an established assurance scheme. This outbreak has, so far, shown no identified link to UK-produced eggs or poultry, with UKHSA’s investigation focused on imported eggs used by some food businesses.
What should I do if I do not know where my eggs come from?
Ask your supplier directly for written confirmation of origin and assurance scheme membership before your next delivery. If they cannot provide it, that is a supplier due diligence gap worth closing immediately, and a natural first item for a HACCP review.
Does this outbreak mean I should stop serving dishes with runny eggs?
Not necessarily, but it is a good reason to check your supply chain and consider pasteurised egg products for raw or lightly cooked dishes, especially if you serve care homes, nurseries, schools, hospitals or any menu aimed at vulnerable groups.
