Swimming in Lake Gödnitz is dangerous! Health department warns about blue-green algae!

Yesterday the Anhalt-Bitterfeld Health Department issued a clear warning: swimming in Lake Gödnitz near Zerbst is prohibited until at least August. The reason for the closure is the blue-green algae that has been identified, which occurs massively in surface water bodies like this, especially in the warm summer months. The effects on health should not be underestimated and range from skin irritations to serious gastrointestinal complaints. The water also poses risks for animals.

Blue-green algae, although often referred to as algae, are actually cyanobacteria. These have the ability to multiply massively when there is sustained warmth and little wind, especially in shallow lakes. Visible signs of such a bloom include greenish or blue-green cloudiness in the water, streaks on the surface or even carpets of algae. If you can't see feet in knee-high water or see dead fish on the surface, you should move away as quickly as possible. The danger affects not only people but also pets, who can come into contact with these bacteria, which can lead to serious poisoning, especially in dogs.

Health risks from blue-green algae

The toxins produced by some blue-green algae cause a variety of ailments: nausea, vomiting, diarrhea, conjunctivitis, ear pain and, in severe cases, even difficulty breathing. People with weakened immune systems, young children and pregnant women are particularly vulnerable to the health risks of these microbes. The distinction between harmless green algae and harmful blue-green algae can only be made in the laboratory, which further complicates the situation.

If you are planning a swim in the lake, it is advisable to find out in advance about the water quality at official bathing areas where regular checks take place. Particularly in times of longer dry periods, such as those we have experienced in recent months, health authorities are particularly vigilant in issuing bathing bans if the level of pollution increases. Also remember: If you notice any skin irritation or other symptoms after bathing, please see a doctor immediately.

A good sign in the region is the Deetz pond, which is currently free of algae and therefore offers a safe alternative for swimmers. But even here, a certain degree of caution is required, because the nutrients from fertilizers, such as phosphorus and nitrogen, sustainably promote the growth of cyanobacteria.

The problem of blue-green algae blooms is exacerbated not only by local weather conditions, but also by climate change. As temperatures rise, it is expected that such toxic blooms will appear earlier and become more common in many bodies of water. This development not only affects bathing fun, but also poses serious health risks. It is therefore extremely important to keep your eyes open and take appropriate precautions.

To prevent danger, dog owners should also ensure that their animals do not come into contact with contaminated water, as there are also major health risks for them. As we all know, prevention is better than cure – so stay safe and informed!*
