A recent study has examined the sources and trends of salmonellosis in Europe, where Salmonella is the leading cause of foodborne illness outbreaks. Through an analysis of outbreak data collected by the European Food Safety Authority (EFSA) across 34 European nations in 2015–2019, eggs were found to be the most significant source of salmonellosis outbreaks in Europe.
The study included a total of 1,508 salmonellosis outbreaks, of which 468 could not be linked to a single food source. Eastern Europe experienced the most outbreaks, and 2018 saw the highest number (366) of outbreaks overall.
