RIVM Report 2014-0011
In 2014, it was shown that 34 out of 36 National Reference Laboratories (NRLs) in the European Union were able to detect high and low levels of Salmonella in chicken faeces. The performance of two laboratories was rated as 'moderate' because of a technical reporting mistake. The laboratories detected Salmonella in 99% of the contaminated samples. This is evident from the 17th interlaboratory comparison study of primary production samples (such as chicken faeces), which was organized by the European Union Reference Laboratory for Salmonella (EURL-Salmonella).
European obligation The study was conducted in March 2014. Participation was obligatory for all EU Member State NRLs that are responsible for the detection of Salmonella in samples from the primary production stage. EURL-Salmonella is part of the Dutch National Institute for Public Health and the Environment (RIVM).
The laboratories detected the Salmonella in the chicken faeces by using the internationally prescribed method Modified Semi-solid Rappaport Vassiliadis (MSRV). Each laboratory received a package of chicken faeces with two different concentrations of Salmonella or containing no Salmonella at all. The laboratories were required to analyse the samples for the presence of Salmonella in accordance with the study protocol.
Control samples In a laboratory analysis, it is necessary for the participants to show that they carried out their analyses in a reliable manner by using 'control samples'. These control samples all gave the desired result. Nonetheless, optimization of these control samples may be desirable.
