ECDC report on Second external quality assurance scheme for Salmonella typing
With this report, ECDC presents the results of the Second external quality assurance scheme for Salmonella typing. Thirty-five laboratories of the Food- and Waterborne Diseases and Zoonoses Network (FWD-Net) participated in this scheme.
ECDC’s external quality assurance (EQA) schemes are designed to identify areas for improvement in laboratory diagnostic and typing methods that are relevant for disease surveillance and to ensure the comparability of results between laboratories. In this scheme, the objective was to evaluate whether serotyping of Salmonella strains by different laboratories within and outside the European Union (28 laboratories are situated in the EU/EEA region) is carried out correctly and lead to similar results.
The results of the EQA scheme indicate that the testing laboratories, on average, accurately serotype Salmonella strains. There are a few remaining problematic areas, mainly in the typing of H antigens and comparability of antimicrobial susceptibility results – highlighting the continuous need for EQA schemes for Salmonella serotyping and the need to develop and implement standard antimicrobial susceptibility testing procedures and interpretation criteria across Europe.Read more:Download the report free of charge
Epidemiological update: multi-country outbreak of Salmonella Enteritidis with MLVA profile 2-9-7-3-2 or 2-9-6-3-2 infections
Since the previous ECDC epidemiological update was published on 30 June 2017, seven EU/EEA countries (Belgium, France, Luxembourg, the Netherlands, Norway, Sweden and the United Kingdom) have reported 96 confirmed and 34 probable new cases associated with the multi-country outbreak of Salmonella Enteritidis with MLVA profiles 2-9-7-3-2 or 2-9-6-3-2 ongoing in the EU/EEA.Read more
Epidemiological update: hepatitis A outbreak in the EU/EEA mostly affecting men who have sex with men
Since the last rapid risk assessment on this multi-country hepatitis A outbreak, 19 EU/EEA countries (Austria, Belgium, Denmark, Estonia, Finland, France, Greece, Ireland, Italy, Latvia, Luxembourg, Malta, the Netherlands, Norway, Portugal, Slovenia, Spain, Sweden and the United Kingdom-England & Wales) have reported 1 363 new outbreak-confirmed cases. Outbreak-confirmed cases are EU/EEA residents with laboratory-confirmed hepatitis A virus (HAV) genotype IA and a sequence with 99.3% homology to one of the three HAV genotype IA outbreak strains (VRD_521_2016; RIVM-HAV16-090; and V16-25801) based on overlapping fragments at the VP1-2a region.Read more
