UK Salmonella Outbreak: One Dead, 207 Ill in Cases Linked to Imported Eggs

Published: 18 Aug 2026, 9:29 pm IST

One person has died and 207 people have fallen ill in a UK salmonella outbreak that health officials say may be linked to eggs imported from outside the UK. The UK Health Security Agency (UKHSA) confirmed the cases on Tuesday, covering infections recorded between 11 August 2025 and 1 August 2026.

The Food Standards Agency (FSA) has been clear on one point: there is no evidence that UK-produced eggs are affected.

The figures so far

The outbreak involves Salmonella Enteritidis, the strain most commonly associated with eggs and laying hens.

Nation	Confirmed cases
England	199
Scotland	6
Wales	1
Northern Ireland	1
Total	207

Within England, London recorded the highest number at 47 cases, followed by Yorkshire and the Humber with 38.

What stands out to public health specialists is not the case count but the severity. 38% of those infected were admitted to hospital — more than one in three. Two patients developed bloodstream infections that UKHSA described as potentially life-threatening.

That hospitalisation rate is unusually high. Salmonella normally causes a self-limiting stomach illness that most healthy adults recover from at home without treatment. A rate approaching 40% suggests either a strain causing more serious illness, a high proportion of vulnerable people affected, or both.

Those infected span an extraordinary age range, from babies to people aged 90.

What officials have said

Hannah Charles, lead epidemiologist for gastrointestinal infections at UKHSA, said the agency is working with the FSA and other public health bodies to investigate an outbreak that may be linked to eggs imported from outside the UK. She noted that salmonellosis is usually caused by eating or handling contaminated food and only rarely spreads from person to person, and that while salmonella generally causes mild illness, people with weakened immune systems may become more seriously unwell.

Jacquelyn McCormick, head of incidents at the FSA, said the exact cause has not yet been identified. Investigations so far have pointed to imported eggs used mainly by food service and catering businesses — restaurants and cafes — as a potential source.

That distinction matters more than most coverage has conveyed. This is not, on current evidence, a supermarket shelf problem. The suspected route runs through catering supply chains, which is also why no product recall has been announced.

Why the timeline is so long

The case window spans nearly twelve months. That is not a sign officials sat on the information — it is how outbreak detection actually works.

Cases are linked using whole genome sequencing, which compares the genetic fingerprint of bacteria from different patients. Infections scattered across a year and four nations look like unrelated food poisoning until sequencing reveals they share a strain. Only then does a cluster become an outbreak, and only then can investigators work backwards through supply chains.

The practical consequence is that a contaminated supply route can operate for months before anyone connects the dots. It also means the true case count is almost certainly higher than 207, because most people with food poisoning never see a doctor and are never tested.

Official egg safety advice

The FSA has not advised people to stop eating eggs. Its guidance is unchanged:

Eggs that are thoroughly cooked and handled hygienically should not present a food safety risk.
Infants, young children, pregnant people and older adults should only eat runny or raw eggs if they carry the British Lion mark or were produced under an equivalent scheme.

The British Lion stamp indicates hens vaccinated against salmonella under a scheme introduced after the UK’s egg crises of the 1980s and 1990s. Vaccination is the single biggest reason British egg safety improved so dramatically — and it is why the FSA can separate UK-produced eggs from the current investigation.

Practical kitchen advice

Beyond the official guidance, standard food hygiene reduces risk substantially:

Cook eggs until both white and yolk are firm if you are in a vulnerable group.
Wash hands after handling raw eggs and shells — contamination can sit on the outside of the shell as well as inside.
Keep raw eggs away from foods eaten uncooked.
Do not wash eggs, which can push bacteria through the porous shell.
Refrigerate eggs consistently rather than moving them between warm and cold.
Be more cautious with homemade mayonnaise, mousse, tiramisu and other dishes using raw egg.

Salmonella symptoms: what to look for

Symptoms typically begin 12 to 72 hours after eating contaminated food and usually last four to seven days. They include:

Diarrhoea
Stomach cramps
Vomiting
Fever

Most people recover without medical treatment, and antibiotics are not routinely given for uncomplicated cases.

When to seek help. UKHSA advises anyone worried about symptoms to contact their GP or the out-of-hours service. Medical advice is particularly important for babies, older adults, pregnant people and anyone with a weakened immune system, and for anyone with signs of dehydration, blood in their stool, a high fever or symptoms lasting beyond about a week.

What foods carry salmonella risk?

Eggs are the most frequently implicated food in UK salmonella outbreaks, but they are not the only one. Salmonella is commonly associated with:

Eggs and egg products
Raw and undercooked poultry
Raw and undercooked meat
Unpasteurised milk and dairy products
Raw fruit and vegetables contaminated at growing or packing stage
Cross-contamination from raw foods to ready-to-eat foods in the kitchen
Contact with reptiles and some pets

FSA research has previously found eggs to be the most common food vehicle in UK salmonella outbreaks, which is why egg-linked clusters draw such rapid regulatory attention.

What happens next

The investigation is ongoing and the source has not been confirmed. Three things are worth watching:

Confirmation of the source. If investigators trace the outbreak to a specific packing centre or exporting country, an FSA food alert or recall could follow.

Whether case numbers rise. Sequencing regularly adds historical cases to a cluster after it is announced, so the total may increase without meaning the outbreak is currently growing.

Whether it extends beyond the UK. Several past European egg outbreaks linked to a single packing centre affected multiple countries simultaneously, and cross-border investigation would follow the same pattern here.

Until then, the practical position is straightforward. UK-produced eggs are not implicated. Thoroughly cooked eggs remain safe. Vulnerable groups should stick to British Lion marked eggs if eating them runny or raw.

Ages affected range from babies to 90-year-olds.
UKHSA and FSA suspect eggs imported from outside the UK, mainly supplied to restaurants and cafes. The exact cause is not confirmed.
The FSA says there is no evidence UK-produced eggs are affected. No recall has been issued.
Thoroughly cooked, hygienically handled eggs are not considered a food safety risk.

FAQs

Is it safe to eat eggs in the UK right now?
- Yes, according to the Food Standards Agency. Eggs that are thoroughly cooked and handled hygienically should not present a food safety risk. The FSA has not advised people to stop eating eggs.
Are British eggs affected by the salmonella outbreak?
- The FSA has stated there is no evidence that UK-produced eggs are affected. Investigations have pointed to eggs imported from outside the UK.
Which eggs are linked to the outbreak?
- Imported eggs supplied mainly to food service and catering businesses such as restaurants and cafes. No specific brand, supplier or country has been publicly confirmed, and no recall has been issued.

Can salmonella spread from person to person?
- Rarely. UKHSA states salmonellosis is most often caused by eating or handling contaminated food, with person-to-person spread being uncommon.
