Every summer, the oysters’ consumption in Arcachon bay is threatened by the presence of a micro-seaweed, revealed by biological and chemical tests. The oyster farmers accuse theses analysis of not being entirely accurate. The real reason would be a much more dangerous pollution situation, mostly linked to human activities.
