  • UK health officials are investigating hundreds of salmonella cases, including one death, potentially linked to imported eggs used in cafes and restaurants.
  • Experts warn that cases are likely to increase until the outbreak's source is identified, a process that can be difficult and take weeks.
  • The UK Health Security Agency is investigating the outbreak, which has seen 474 confirmed cases, with imported eggs commonly used in catering being the suspected culprit.

The United Kingdom is grappling with a surge in salmonella cases, with health experts warning that infections are likely to continue rising until the elusive source is identified. The UK Health Security Agency (UKHSA) has confirmed 474 cases and one death linked to the current outbreak.

Bought in bulk these eggs are cheaper than UK lion mark eggs and so can end up being used in schools and nursing homes along with cafes, restaurants and takeaways.

Investigations suggest the outbreak is associated with imported eggs used in cafes and restaurants. These imported eggs are often cheaper than domestically produced, British Lion-stamped eggs, making them a common choice for catering in schools, nursing homes, cafes, and takeaways. Experts note that the clustering of cases points to a potential single source, though identifying it is challenging.

As far as controls and the future, it’s difficult to judge, though identification of the source would help in being able to put specific controls on a producer or country in place.

— Paul WigleyProfessor of animal microbial ecosystems at the University of Bristol, discussing the challenges of controlling the outbreak.

Professor Paul Wigley of the University of Bristol highlighted the difficulty in pinpointing the origin, especially when eggs are used in food service. He advised that avoiding eggs served outside the home, unless they are British Lion-marked, might be the only preventative measure individuals can take. The UK imports approximately 1.6 billion eggs annually, a figure that has risen by 60% since 2021.

Avoiding runny eggs outside the home, unless lion mark eggs, is perhaps the only step an individual can make.

— Paul WigleyProfessor of animal microbial ecosystems at the University of Bristol, advising on personal precautions.

Professor Chris Elliott from Queen's University Belfast expressed concern over the difficulty in tracing the source, particularly within the food service industry where supply chains are less transparent than in retail. He anticipates that case numbers will continue to climb until the country of origin can be definitively identified, a process that could take weeks rather than days. Elliott cautioned against premature conclusions, emphasizing the pressure on agencies to accurately identify the source without speculation.

All we have been told is that the likelihood is that it’s been imported.

— Prof Chris ElliottProfessor at the school of biological sciences at Queen’s University Belfast, commenting on the suspected origin of the outbreak.
