| Following a flooding event close to a shellfish production lagoon, 205 cases of gastroenteritis were linked to oyster consumption. Twelve stool samples from different individuals were collected. Analysis showed that eight samples were positive for multiple enteric viruses, and one stool sample had seven different enteric viruses. Analysis of shellfish implicated in the outbreak allowed detection of the same diversity of enteric viruses, with some viral genomic sequences being identical to those obtained from stool sample analysis. Shellfish were contaminated by as many as five different enteric viruses. For the first time in Europe, Aichi virus was identified in oyster samples. Shellfish samples collected over 3 weeks following the outbreak showed a... |

| Shellfish filter large volumes of water to meet their nutritional requirements and thus ingest phytoplankton, but also concentrate microorganisms naturally present in water (vibrios, phycotoxins) or of fecal origin (enteric viruses, enterobacteria, protozoan). The analysis of data from systems contributing to the surveillance of foodborne illnesses associated with shellfish consumption and from published outbreak investigations shows that, in France, foodborne illnesses associated with shellfish consumption are mainly of viral origin, mostly due to norovirus followed by hepatitis A virus. The risk linked to phycotoxins appears low and the one related to enterobacteria and vibrios very low. The mandatory notification (MN) of foodborne outbreaks remains the... |
