UK Health Officials Investigate Salmonella Outbreak Linked to Imported Eggs

Health authorities in the United Kingdom are currently managing a significant public health challenge following a nationwide outbreak of salmonella. According to The Guardian Health, more than 200 people have fallen ill, and one person has died. This situation follows a difficult period for food safety globally, including a recent, separate, and massive egg recall in the United States, where officials upgraded their warning to the highest risk level after nearly 100 people became sick across 17 states.

In the UK, the outbreak has affected a wide range of people, from infants under one year old to elderly individuals up to 90 years of age. The UK Health Security Agency (UKHSA) is leading the investigation into how the bacteria spread. Their findings suggest that the illnesses are linked to eating contaminated eggs at cafes and restaurants rather than at home. Importantly, the UKHSA has stated that there is no evidence linking the outbreak to eggs produced within the UK. Instead, current investigations point toward eggs imported from other countries.

Salmonella causes an illness known as salmonellosis, which typically results in stomach cramps, diarrhoea, fever, and vomiting. While many people recover without needing medical help, the situation in the UK has been severe for some. At least 34 people have required hospital treatment, with two individuals suffering from a dangerous bloodstream infection. The UKHSA noted that they are using whole-genome sequencing—a scientific method to study the genetic code of the bacteria—to confirm that all 207 cases are connected to the same specific strain of salmonella.

Most of the cases have been reported in England, with smaller numbers identified in Scotland, Wales, and Northern Ireland. London and the Yorkshire and the Humber region have seen the highest numbers of people affected. The UKHSA is working closely with the Food Standards Agency and European health partners to track the supply chain and identify exactly where the contamination began. Dr. Safi Rehman, a research associate at King’s College London, noted that this is not an isolated event. He explained that this outbreak is genetically similar to a previous one in 2025, which was also connected to imported eggs.

Investigators have interviewed 114 of the people who became ill to find common links. These interviews identified five specific food businesses where multiple people had eaten in the week before they started feeling sick. While the agency has not named these businesses, they confirmed that these locations received eggs from several different suppliers, including egg importers. In two of these cases, officials also found evidence of cross-contamination, which happens when bacteria move from one food or surface to another.

Hannah Charles, the lead epidemiologist—a scientist who studies how diseases spread—for gastrointestinal infections at the UKHSA, emphasized the importance of safety. She explained that while salmonella usually causes mild illness, it can be very dangerous for vulnerable people, such as those with weakened immune systems. She advised the public to wash their hands thoroughly after using the bathroom and before handling food. Furthermore, she stressed that cooking food completely is essential to killing the bacteria.

As the investigation continues, the UKHSA has promised to keep the public informed. Because the investigation into the death is still ongoing, officials have not released details regarding the person who passed away. For now, the focus remains on identifying the exact source of the imported eggs to prevent any more cases. Anyone who is worried about their health or who has symptoms is encouraged to contact their doctor or a local out-of-hours health service for advice.
