#  Mystery Salmonella outbreak

 Written on 01 June 2025.

Health authorities have launched a national investigation into a Salmonella outbreak that has affected 25 people across the United Kingdom, resulting in five hospitalizations. The cases involve a rare strain of the bacteria known as Salmonella Saint Paul, which has sickened at least 20 individuals, including 13 young children.

The outbreak cases span multiple regions throughout the UK rather than being concentrated in a single area, and all patients fell ill during the specified timeframe, with no new cases identified since March 2025. The current outbreak involves the same Salmonella saintpaul strain that caused a significant outbreak in 2023, which was linked to imported cantaloupe melons and affected more than 90 people. However, health officials have found no evidence connecting cantaloupe to the current outbreak, and the source remains under investigation.
