Algae alarm in Cottbus: Swimming in Madlower and Branitzer See is dangerous!

There is a sense of alarm in Cottbus: toxic blue-green algae have been found in two popular bathing lakes, the Madlower Badesee and the Branitzer See. The city administration urges you not to go swimming in these waters. This warning is no coincidence - blue-green algae produce toxic substances that can cause nausea, diarrhea and even skin irritation upon contact. There is also a danger for our four-legged friends, because dogs should neither drink nor play in order to prevent dangerous poisoning.

The causes of the alarming algae plague are diverse. High temperatures and an excess of nutrients in the water promote the rapid multiplication of these cyanobacteria. Although the temperatures of the last few days indicate rather cooler values, the algae still seem to be active. The health department has already started investigations to find out the reason for the sudden appearance of these bacteria. The official confirmation of the suspicion was supported by the investigations of city spokeswoman Mary-Ann Basto, who also announced that the toxic algae were discovered during routine sampling. According to lr-online.de, information signs will be put up for safety reasons as soon as the suspicion is officially confirmed.

What are blue-green algae?

Cyanobacteria, commonly known as blue-green algae, are not only notorious for their beauty; They are among the oldest living things on our planet and are capable of photosynthesis. However, they can also produce harmful toxins which, when present in large quantities, pose health risks. According to n-tv.de, rapid growth is particularly evident at higher temperatures and an excess supply of nutrients. These algae can leave behind greenish or red cloudy water, which significantly limits visibility in lakes and can therefore endanger rescue measures.

Experts warn that skin and mucous membrane irritation is not uncommon upon contact with these bacteria, and small children and dogs are particularly at risk. While the health risks are often less serious for adults, the toxins can be life-threatening for animals, especially dogs. Accordingly, all retention measures in water bodies should be observed and warnings taken seriously, as can be found on the [LGL Bayern] website (https://www.lgl.bayern.de/gesundheit/hygiene/wasserhygiene/badeseen/cyanobacterien_blaualgen.htm).

The Cottbus bathing lakes should therefore be avoided for the time being until a final clarification has been made. Given the weather forecast with temperatures of around 23 to 25 degrees, urgent action seems necessary to protect the health of bathers and their loyal companions. Swimming in Cottbus waters is currently at your own risk, and suitable weather does not arm you against the dangers of depressive water biology.
