European Listeria typing exercise (ELiTE) in ready to eat foods found fish products as a significant source

A joint study of the European Centre for Disease Prevention and Control (ECDC), European Food Safety Authority (EFSA), and the European Union Reference Laboratory for Listeria monocytogenes (EURL Lm, hosted by the French Agency for Food, Environmental and Occupational Health & Safety - ANSES) was commissioned. In February 2010, ECDC invited the National Public Health Laboratories (NPHRLs) to start storing all available L. monocytogenes isolates with accompanying background data from human cases of listeriosis voluntarily until the end of 2011. This collaborative study, called ‘the European Listeria Typing Exercise’ (ELiTE). The goal of the study was to describe the molecular epidemiology of L. monocytogenes in humans and food. The most significant human-food cluster involved 30 human and 56 food L. monocytogenes isolates from 15 countries. Fishery products showed a high prevalence of L. monocytogenes with the highest proportion of samples with bacteria counts exceeding microbiological criterion 100 cfu/g. @
