A temporary ban on the marketing of oysters from certain sites on the West Coast due to health reasons has led to a catastrophic situation for producers, with people no longer buying their oysters. The ban affects production areas in the Arcachon basin, Calvados, and La Manche, and producers are experiencing a significant decrease in sales, especially during the important end-of-year celebrations. The Secretary of State for the Sea has acknowledged the issue and promised additional aid to support producers affected by the ban.
