Impact of Xynthia Tempest on Viral Contamination of Shellfish

Abstract

Viral contamination in oyster and mussel samples was evaluated after a massive storm with hurricane wind named "Xynthia tempest" destroyed a number of sewage treatment plants in an area harboring many shellfish farms. Although up to 90% of samples were found to be contaminated 2 days after the disaster, detected viral concentrations were low. A 1-month follow-up showed a rapid decrease in the number of positive samples, even for norovirus.
