​This report presents the results of the sixth round of the Salmonella External Quality Assessment (EQA) scheme for typing of Salmonella enterica spp. enterica (further EQA-6). The EQA covers the methods pulsed field gel electrophoresis (PFGE) and multiple locus variable number of tandem repeat analysis (MLVA). A total of 29 laboratories signed up for the EQA-6 that took place from October 2014 to March 2015, with 26 laboratories submitting results.

Executive summary

Salmonellosis is the second most commonly reported zoonotic disease in the EU, and Salmonella is a common cause of foodborne outbreaks

Since 2007, ECDC has been responsible for the EU-wide surveillance of salmonellosis and listeriosis, and facilitates the detection and investigation of foodborne outbreaks. Surveillance data, including some basic typing parameters for the isolated pathogens, are reported by Member States to the European Surveillance System (TESSy). The molecular surveillance system that has been implemented as part of TESSy relies on the capacity of the laboratories to produce comparable typing results.
