Another 50 people have fallen sick as part of three related Salmonella outbreaks in the United Kingdom.

The UK Health Security Agency (UKHSA), Food Standards Agency (FSA), and other public health bodies are investigating the Salmonella Enteritidis clusters which have affected more than 500 people.

Genetic relatedness of the clusters, along with food information, suggests they are associated with eating imported eggs at small cafés, restaurants, and takeaways.

In the first cluster, there have been 305 confirmed cases and one death. Sample dates range from Aug. 11, 2025, to Aug. 21, 2026. In the past month, 168 infections have been reported in England.

Sick people range in age from younger than 1 to 90 years old with a median age of 30. Of 160 cases with available information, 42 have been admitted to hospitals. 

The European Centre for Disease Prevention and Control (ECDC) is also investigating this Salmonella Enteritidis sequence type 11 cluster.

In July, the Dutch National Institute for Public Health and the Environment (RIVM) restarted an investigation into a Salmonella Enteritidis outbreak that began in spring 2025. There are 111 patients with 31 in 2026, including 10 in June and eight in July. Only seven patient interview questionnaires have been received by RIVM, with the agency saying it is too early to draw any conclusions about the outbreak’s source.

There are also 15 cases in Belgium, two in Austria, one in Denmark, four in France, and six in Germany. At least 34 people have been hospitalized.

Other clusters and Scotland situation
In a second cluster, there are 182 cases in England. Sample dates range from May 27, 2025, to Aug. 15, 2026. Patients are aged between younger than 1 to 92 with a median of 29 years old. Of 39 patients with information available, 20 were admitted to hospitals.

In a third cluster, there are 41 cases and one death, with sample dates ranging from Jan. 27 to Aug. 11, 2026. Cases range in age from under 1 to 87 with a median of 35 years old. Five people have been hospitalized.

In Scotland, dates of illness are from April 1 to Aug. 10, 2026, for 13 patients. Cases range in age from 2 to 78 with a median of 36 years old and 10 are female.

About Salmonella infections
Food contaminated with Salmonella bacteria does not usually look, smell, or taste spoiled. Anyone can become sick with a Salmonella infection. Infants, children, seniors, and people with weakened immune systems are at higher risk of serious illness because their immune systems are fragile.

Anyone who has developed symptoms of Salmonella infection should seek medical attention. Sick people should tell their doctors about the possible exposure to Salmonella bacteria because special tests are necessary to diagnose salmonellosis. Salmonella infection symptoms can mimic other illnesses, frequently leading to misdiagnosis.

Symptoms of Salmonella infection can include diarrhea, abdominal cramps, and fever within 12 to 72 hours after eating contaminated food. Otherwise, healthy adults are usually sick for four to seven days. In some cases, however, diarrhea may be so severe that patients require hospitalization.

Older adults, children, pregnant women, and people with weakened immune systems, such as cancer patients, are more likely to develop a severe illness and serious, sometimes life-threatening conditions.

Some people get infected without getting sick or showing any symptoms. However, they may still spread the infections to others.
