The health ministry has issued a further warning of the presence of the dangerous cyanobacteria, or blue algae, on different parts of the Moselle.
In a communiqué issued on 8 August, the public were informed that, “Cyanobacteria, also known as "blue-green algae", have been found in different places along the Moselle River, especially in slow traffic areas. They are bacteria that are normally present in these waters but which, under certain conditions, develop excessively and form blue-greenish coloured carpets.”
Under these conditions, these bacteria may produce toxins that can cause health problems for humans and animals. The types of problems depend on the amount of toxins absorbed but include: skin irritations, headaches, nausea, gastroenteritis, cramps, paralysis and even liver damage.
The health ministry states that the exact cause of this excessive proliferation is not known, but often results from an inadequate supply of nutrients for these bacteria where the water temperature is high.
It recommends, therefore, that the public (and their pets) avoid all contact with water where these coloured carpets can be seen.
