Red alert! Health hazard from blue-green algae at the Bleilochtalsperre!

Red alert! Health hazard from blue-green algae at the Bleilochtalsperre!

This summer time the sun can be seen in all its glory, but that also means increased attention to our waters. There is currently a warning for the Bleiloch Dam in the Saale-Orla district, which warns of health risks from blue-green algae, also known as cyanobacteria. Rising temperatures and an increase in phosphate and nutrients in the water promote algae growth and the possibility of toxic blue-green algae cannot be ruled out, such as MDR informed.

The district office has therefore strongly advised people not to bathe in the water, especially children and small children. Additionally, dogs and other pets should not drink from the water. Swimming or even just immersing yourself in the water can pose health risks. In adults, symptoms such as nausea, vomiting and diarrhea may occur. In severe cases, a large amount of water can lead to respiratory paralysis and even life-threatening conditions.

Algae growth also in other regions

A similar situation has developed in Schleswig-Holstein, where rising temperatures promote algae growth in water bodies. While the water quality there is largely good according to the Ministry of Health, the first warnings have already been issued about blue-green algae in some bathing lakes, such as 24hamburg reported. Affected lakes include Bordesholm and Neversdorfer See, while there are also temporary bathing bans at Wardersee and Brahmsee.

Health authorities regularly monitor the swimming season, which runs until September 15th. Ongoing sampling and site visits take place there to ensure water quality. People with weakened immune systems, small children and pregnant women are particularly at risk. When examining these groups, special attention must be paid because toxic cyanotoxins in some types of algae can cause health problems.

Recommendations for bathers

Attention is also paid to water quality at Bostalsee. Recent checks show visible signs of cyanobacteria, but the situation is still under control and there is no ban on swimming. However, the visibility depth is less than two meters, which indicates increased algae growth. Like on the Bostalsee website bostalsee.de can be read, bathers are advised to avoid areas with visible algae accumulations and to shower thoroughly after bathing.

In summary, it is important to take the warnings seriously and act preventatively to protect your own health and that of others. The summer heat brings not only joy but also risks that we should not ignore.
