Proficiency Tests
The EURL regularly organises proficiency tests (PTs) for the national reference laboratories (NRLs) on methods of laboratory analysis for Campylobacter in different matrices of food or animal origin. The PTs are organised in line with EN ISO 17043 and EN ISO 22117.
Below is a list of PTs organised by the EURL-Campylobacter. The PT reports are available by clicking corresponding PT number. The reports are anonymised and classified according to the Swedish Public Access to Information and Secrecy Act Chapter 15, 1 a ยง, 30:23 and 31:12.
of
PT38 Whole genome sequencing and cluster analysis of Campylobacter
The objective of this proficiency test (PT) was to assess the quality of whole genome sequence (WGS) data and accuracy of cluster analysis of Campylobacter performed by the NRLs .
PT36 Enumeration (and voluntary species identification) of Campylobacter
The objective was to assess the performance of the NRLs to enumerate Campylobacter in chicken meat, with species identification as a voluntary part.
PT35 Detection and species identification of Campylobacter spp.
The objective was to assess the performance of the NRLs to detect and identify Campylobacter in boot sock samples.
PT34 Enumeration (and voluntary species identification) of Campylobacter
The objective was to assess the performance of the NRLs to enumerate Campylobacter in chicken skin, with species identification as a voluntary part.
PT33 Whole genome sequencing and cluster analysis of Campylobacter
The objective of this proficiency test (PT) was to assess the quality of whole genome sequence (WGS) data and accuracy of cluster analysis of Campylobacter performed by the NRLs.
PT32 Detection and species identification of Campylobacter
The objective was to assess the performance of the NRLs to detect and identify Campylobacter in pig faeces.
PT31 Enumeration (and species identification) of Campylobacter
The objective was to assess the performance of the NRLs to enumerate Campylobacter in chicken skin, with species identification as a voluntary part.
PT30 Detection and species identification of Campylobacter
The objective was to assess the performance of the NRLs to detect and identify Campylobacter in raw cow's milk.
