This report contains a summary of the presentations given at the 21st annual workshop for the European National Reference Laboratories (NRLs) for Salmonella (9 June 2016). The aim of the workshop is to facilitate the exchange of information on the activities of the NRLs and the European Union Reference Laboratory for Salmonella (EURL-Salmonella).
Annual ring trials A recurring item at the workshops is the presentation of the results of the annual ring trials organised by the EURL. These ring trials give information on the quality of the NRL laboratories tested. The 2015 trial showed that all NRLs were able to detect Salmonella in whole liquid egg. Detailed information on the results per ring trial is given in separate RIVM-reports.
Molecular techniques Several presentations provided information on the use of molecular techniques for Salmonella typing. These techniques analyse the DNA of the bacterium, and are often used to trace pathogens in food, animals or humans. Each strain has its own unique molecular typing pattern.
Storage of molecular typing results The European Food Safety Authority (EFSA) presented a database for storage of the molecular Salmonella typing results. This database has been available since early 2016 and will make it possible to check whether a specific strain is found in different countries and products.
The annual workshop is organised by the EURL-Salmonella, part of the Dutch National Institute for Public Health and the Environment. The main task of the EURL-Salmonella is to evaluate the performance of the European NRLs in detecting and typing Salmonella in different products.
