Cyanobacteria in Slovenia

Cyanobacteria (often called blue-green algae) are present in many Slovenian freshwaters, including popular alpine and lowland lakes. While Slovenia boasts some of the cleanest water in the EU, massive cyanobacterial blooms and toxic biofilms are an emerging environmental and health risk, as there is no systematic state monitoring of them.

Health Risks to Humans and Pets

Pets: Dogs are highly vulnerable, as they frequently ingest water or lick slimy sticks from the shore. Anatoxin produced by cyanobacteria can be fatal to dogs within hours.
Humans: Ingesting toxins can cause severe gastroenteritis (diarrhea, vomiting), while skin contact can lead to rashes, eye irritation, and hay fever-like symptoms.
