Conventional depuration will not eliminate noroviruses from oyster tissue (Le Guyader, 2006).

Norovirus, highly contagious

Noroviruses are highly contagious and 10-100 viral particles may be sufficient to infect an individual. They are transmitted primarily through the faecal-oral route, either by consumption of contaminated food or water, or by spreading directly from person to person. Vomiting creates aerosols with high content of virus particles, which enter the oral mucosa or contaminate surfaces. The virus survives a long time on different surfaces and thus, environment may serve as a source of new infections. For more information on norovirus check the ECDC website.
