Following an increase in the number of reported human infections with Salmonella entrica serovar Stanley in some EU countries, the European Commission requested a risk assessment from ECDC.
It concludes that the emergence of cases in three EU countries (Belgium, Germany and Hungary) without documented travel history outside the EU in the same period of time and with a specific age distribution, common antibiotic-resistance profile and PFGE pattern confirms an epidemiological and microbiological link.
These cases are not considered to be related to international travel but the source has not yet been identified. Investigations are ongoing and it is likely that more cases will be identified. However, the impact on public health across the EU is considered to be limited.
