Listeria surveillance: new EU-wide study reveals that most outbreaks remain undetected
More than half of the severe listeriosis cases in the European Union belong to clusters, many of which are not being picked up fast enough by the current surveillance system, suggests a new article published in Eurosurveillance. The large-scale study looked into listeriosis epidemiology through whole genome sequencing and found that this method, when implemented at EU-level, could lead to faster detection of multi-country outbreaks, saving up to 5 months of the investigations.
Multi-country outbreak of Listeria monocytogenes sequence type 8 infections linked to consumption of salmon products
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).
