Salmonella outbreak update
UK health agencies are investigating a Salmonella Enteritidis outbreak linked to imported eggs, with 259 confirmed cases and one death reported as of 25 August 2026. The risk to the public remains low, though vulnerable groups are advised to take precautions.
The UK Health Security Agency (UKHSA), Food Standards Agency (FSA) and public health partners are investigating an outbreak of Salmonella Enteritidis t5.9411 in the UK, with 259 confirmed cases and one death reported as of 25 August 2026. The outbreak is linked to eggs imported from abroad, with cases primarily associated with eating out at small cafés, restaurants and takeaway businesses. Sample dates for cases range from 11 August 2025 to 8 August 2026, and the investigation remains ongoing.
Two additional genetically distinct clusters of Salmonella Enteritidis (t0.24068 and t5.9765) have been identified, with case numbers rising since June 2026. The t0.24068 cluster has 177 confirmed cases in England with no deaths, while the t5.9765 cluster has 38 cases and one death. All three clusters are being investigated in parallel due to potential links to imported eggs.
The UKHSA states the overall risk to the general public from Salmonella remains low, though vulnerable groups—such as young children, elderly individuals, pregnant women and immunocompromised people—are at higher risk of severe illness. The FSA advises that these groups can safely consume raw or lightly cooked eggs only if they carry the British Lion mark or are produced under the Laid in Britain assurance scheme.
Salmonella infection typically causes mild symptoms like diarrhoea, stomach cramps and fever, but can lead to serious complications in vulnerable individuals. The UKHSA continues to work with the FSA and other agencies to investigate the outbreaks, which are linked to imported eggs. Thoroughly cooked eggs pose no food safety risk, and good hygiene practices remain essential to prevent infection.
