EURL-Salmonella ringonderzoek levende tweekleppige weekdieren 2024. Detectie van Salmonella in mosselen

Abstract
In 2024 hebben 21 van de 22 Nationale Referentie Laboratoria voor Salmonella (NRL's-Salmonella) een goede score gehaald in het ringonderzoek voor de Salmonella-bacterie. Eén laboratorium heeft wel de verwachte resultaten gehaald, maar gebruikte niet de voorgeschreven methode. Daarom is dit keer voor dit laboratorium geen score bepaald. Alle lidstaten van de Europese Unie hebben een NRL-Salmonella. Deze NRL's zijn verplicht om elk jaar hun kwaliteit te laten toetsen met verschillende zogeheten ringonderzoeken. Een van de ringonderzoeken controleert of de NRL's de Salmonella-bacterie in levende tweekleppige weekdieren kunnen aantonen; dit keer in mosselen. Elk lidstaat van de EU wijst hiervoor het NRL aan dat verantwoordelijk is voor deze testen in hun laboratorium. De 22 deelnemers in dit ringonderzoek kwamen uit 19 lidstaten van de Europese Unie en uit drie andere Europese landen. De laboratoria gebruikten een verplichte, internationaal erkende analysemethode om Salmonella in mossel monsters aan te tonen. Elk laboratorium moest volgens een protocol zelf de mosselen openmaken en besmetten met Salmonella. Het Europese Unie Referentie Laboratorium voor Salmonella (EURL-Salmonella) leverde zowel de mosselen als de Salmonella-materialen. Het EURL-Salmonella organiseerde het ringonderzoek. Het EURL-Salmonella ziet toe op de kwaliteit van de NRL's-Salmonella in de Europese Unie en is gevestigd bij het RIVM.
In 2024, 21 out of 22 National Reference Laboratories for Salmonella (NRLs-Salmonella) obtained a good score in a Proficiency Test for the Salmonella bacteria. One laboratory found the expected results, but did not use the prescribed method. As a result, the performance of this laboratory was not assessed. All European Union (EU) Member States have an NRL-Salmonella. The NRLs are obliged to participate in annual quality monitoring exercises, known as Proficiency Tests. One of these Proficiency Tests checks whether NRLs are able to detect Salmonella bacteria in live bivalve molluscs; this time in mussels. Each EU Member State has to appoint an NRL that is responsible for performing these tests in its laboratory. The 22 participants in this Proficiency Test were NRLs-Salmonella from 19 EU Member States and three NRLs-Salmonella from other European countries. The laboratories used an obligatory, internationally accepted method to detect the presence of Salmonella in mussels. Each laboratory had to follow a protocol to open the mussels and to artificially contaminate them with Salmonella. Both the mussels and the Salmonella materials were provided by the European Union Reference Laboratory for Salmonella (EURL-Salmonella). This proficiency test was organised by EURL-Salmonella. EURL-Salmonella monitors the performance of the NRLs-Salmonella in the European Union and is part of the National Institute for Public Health and the Environment (RIVM).
