This report presents the results of the 11th round of the external quality assessment (EQA-11) scheme for typing of Salmonella enterica subsp. enterica organised for the national public health national reference laboratories (NPHRLs) in ECDC’s Food- and Waterborne Diseases and Zoonoses network (FWD-Net) managed by the European Centre for Disease Prevention and Control (ECDC). The EQA-11 scheme was arranged by the Section for Foodborne Infections at the Statens Serum Institut (SSI) in Denmark.
Since January 2019, 121 cases of Salmonella enterica infections with six different serotypes linked to sesame-based products have been reported in five EU/EEA countries.
Five European countries have reported salmonellosis infections linked to the consumption of sesame-based products, such as tahini and halva, imported from Syria.
The Protocol is targeted at the national public health reference laboratories to guide the susceptibility testing needed for EU surveillance and the reporting to ECDC.
Between 15 March and 6 July 2021, 348 confirmed S. Braenderup sequence type 22 (ST22) cases were reported in 12 European Union/European Economic Area (EU/EEA) countries and the United Kingdom (UK).
ECDC is supporting a large number of targeted External Quality Assessment (EQA) schemes with voluntary participation by reference or primary laboratories, which are active members of EU surveillance networks.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 16-22 May 2021 and includes updates on COVID-19, influenza, measles, Salmonella Braenderup, Ebola virus disease and cholera.
This report presents the results of the fourth round of the EQA on AST for national public health laboratories on Salmonella (hereafter Salmonella EQA4-AST) within the Food- and Waterborne Diseases and Zoonoses Network (FWD-Net).
