Toxic blue-green algae bloom

During summer 2017, the Centre-Val de Loire Region was affected by blue-green algae contaminated water, resulting in the poisoning and death of dogs that had swum in the rivers (the Cher and the Vienne) in the Centre-Val de Loire region and in Maine-et-Loire (the Loire). As a result, several areas where swimming is usually supervised and permitted were temporarily closed by prefectural decision. In Maine-et-Loire, fishing for consumption was also banned during the contamination period.
