Few people realise that when they get ill from eating an oyster or other shellfish it is often because it contains norovirus. And once someone has gone down with this ‘food poisoning’, those around them can catch the highly contagious virus without even eating the food that was the source.
Ian Clarke, a professor of molecular microbiology and virology at the University of Southampton and an expert on norovirus, says that oysters are a common source of outbreaks. ‘It can start by one person eating a norovirus-contaminated oyster and then passing the virus on by person-to-person contact.’
