Suspected blue-green algae in Danube River sickens two

The suspicion of blue-green algae in the Danube River has intensified in Lower Bavaria after two individuals reported symptoms of nausea, vomiting, and diarrhea. The pair had spent extended periods in the water during a boat trip between Vohburg an der Donau and Kelheim.

Both individuals have since recovered. However, their illness has strengthened the belief that a bloom of cyanobacteria, commonly known as blue-green algae, is present. Water samples are still pending to confirm the presence of these bacteria. The district office has issued a strong warning advising against swimming in the Danube for both people and animals.

This warning follows earlier alerts after several dogs became ill, and one died, subsequent to swimming in the river. Cyanobacteria can produce toxins that cause skin and mucous membrane irritation, allergic reactions, and gastrointestinal issues. For dogs, exposure can be life-threatening, especially if they ingest contaminated water or chew on affected sticks.

From swimming in the Danube, it is still strongly advised against – for humans as well as animals.
