The Ministry of Health confirms the presence of blue-green algae in various regions of the Moselle.

It's that time of year again: cyanobacteria, also known as blue-green algae, have been found in the Moselle.

They're easily identifiable by their blue-green appearance on the water's surface, and normally emerge in areas of slowed water circulation. The high temperatures enable an even more rapid growth.

The Ministry of Health stresses the need for caution around the algae: when they appear in large quantities, they become harmful as they produce toxins known to put at risk both human and animal health. Symptoms usually include skin irritation, headaches, nausea, cramps, gastroenteritis, paralysis, and liver damage.

It is strongly recommended that you check the current's state when going to the river. Should you spot the cyanobacteria, avoid swimming and water sports. Also remember to prevent pets from entering the water or drink from it.
