A prolonged genomic cluster of 20 human Listeria monocytogenes ST1607 infections has been reported. The most recent case was reported in March 2024 in Denmark.
Twenty-one cases of Listeria monocytogenes IVb sequence type ST 6 infections have been reported from the Netherlands (19 cases) and Belgium (two cases). This outbreak was identified using whole genome sequencing (WGS) analysis.
This joint ECDC-EFSA rapid outbreak assessment provides an assessment of the cross-border public health risk related to L. monocytogenes infections linked to the consumption of cold-smoked fish products, possibly originating from a single food processing company.
A multi-country outbreak of 12 listeriosis cases caused by Listeria monocytogenes sequence type (ST) 8 has been identified through whole genome sequencing (WGS) analysis in three EU/EEA countries: Denmark (6 cases), Germany (5) and France (1).
This document provides an updated assessment of the cross-border public health risk associated with consumption of frozen corn and possibly linked to other frozen vegetables contaminated with L. monocytogenes.
