Toxic blue algae in the Greifswald Bodden: bathing ban for everyone!

A hot summer is just around the corner, but swimming on the Greifswald Bodden can become a real danger. The health department of the Vorpommern-Greifswald district has issued a warning today due to a routine measurement. Toxic blue algae, also called cyanobacteria, were found. Above all, toddlers, pregnant women and immunocompromised people should be careful because they can produce algae harmful substances. But our four-legged friends are not excluded either, reported the Ostsee-Zeitung .

While Germany's temperatures increase up to 34 degrees Celsius, the risk of forming blue -green algae also increases. These thrive especially with a lot of sun and low water movement. The east wind is currently pressing the algae on the coast, but the weather conditions could relax at night and offer the algae a little less habitat. So if you hope to cool down, you should be careful!

alarm level red: warnings and precautionary measures

The district has already set up warning signs to inform the bathers. Visible signs of blue algae are bluish-green cloudings, feasty coverings and a musty smell. If you meet such signs, the health department advises to avoid the bathing area. Because the contact with contaminated water can cause skin irritation and allergic reactions. When swallowed, nausea, vomiting and diarrhea are possible, such as the Nordkurier

For the next few days, the bathing water controls are more important than ever. These have been running at 57 bathing spots in Greifswald, Anklam and Pasewalk since May 5. Values ​​such as pH value and depth of vision are checked. But not only the Greifswald Bodden is affected - other areas could also be affected, which is why caution is announced.

alternatives to bathing

Don't worry, there are alternatives! The water in Eldena, Lubmin and Loissin is currently harmless and can be used for refreshing cooling. André Bleckmann, the head of the DLRG Greifswald, confirms that the water in Eldena is clear and free of Blau algae. So nothing stands in the way of a relaxed bathing day!

Overall, it is important to have a good hand with the bathing plans in the current weather situation. It is best to always pay attention to the visibility of the water quality and, if in doubt, prefer to choose another bathing area. After all, summer should bring relaxation and no health risks!
