Blue danger in the Great Sea: Health authorities warn of blue-green algae!

There is currently a reason to be mindful at the “Großes Meer” natural lake in the Aurich district. As NWZ Online reports, a routine water test revealed light streaks, which may indicate the first signs of blue-green algae. This group of cyanobacteria thrives in warm weather and little wind. However, a health department spokesman reassures: There is currently no ban on swimming and no acute health risk.

The sampling was carried out as part of regular water quality monitoring and the samples taken are now being analyzed in the laboratory for their exact composition. The results are expected in the next two days. Until then, the health department is urging bathers to be careful. If there are noticeable changes in the water, swimmers should avoid jumping into the cool water.

What are blue-green algae?

Blue-green algae is not actually algae, but bacteria and can release dangerous toxins that can harm both humans and animals. According to the Umweltbundesamt, increased concentrations of cyanobacteria in water bodies during the bathing season can pose health risks. Especially in warm summers, prolonged heat and stagnant water temperatures can lead to a mass development of these bacteria.

Amazingly, the thick, green-blue carpets and heavy turbidity of waters are reports that are more common among the population during the summer months. In an analysis of 16 lakes, satellite image-based evaluations did not show any clear trends in cyanobacteria contamination, emphasizes the Federal Environment Agency. The cause of such developments in stagnant water is usually the increased concentration of phosphorus, which contributes to the growth of cyanobacteria.

Ensure safe bathing experiences

In the Aurich district, the water quality of bathing water is regularly monitored to ensure that EU bathing water regulations are met. The Aurich district actively informs the population about bathing water quality and warns of health risks as soon as they are identified. This is particularly important because symptoms such as skin irritation or gastrointestinal diseases can also be due to other pathogenic bacteria.

So the coming days will be crucial. The water tests will provide information about whether the initial streaks continue to develop or whether bathers can continue to spend the summer in and around the “Great Sea” without any worries. Until things are clarified, you should enjoy bathing with caution - and if in doubt, it is better to avoid bathing if there is any uncertainty.
