An alert has been issued by the Main Sanitary Inspectorate of Poland, resulting in the closure of 18 bathing sites along the Baltic Sea’s coast due to the presence of cyanobacteria, commonly known as blue-green algae. This precautionary measure was announced on 18th July following the detection of potentially harmful algal blooms.

Among the closed bathing areas are popular spots such as Hel’s “Duża Plaża”, multiple sites in Jastarnia, including Jastarnia Leśna and Jastarnia Ogrodowa, and a variety of locations in Sopot including sites near Molo and Łazienki Południowe II. As a result, red flags were hoisted, indicating the prohibition of swimming until further notice.

Cyanobacteria, one of the earth’s oldest organisms, are capable of adapting to diverse environmental conditions, often thriving in both saline and freshwater bodies. Their proliferation is usually encouraged by high water temperatures, increased biological salts like phosphates, light winds, and a lack of rainfall, all of which currently characterize the region.

The health implications of these blooms can be concerning. Human contact with contaminated water can result in skin irritations, eye redness, and more severe gastrointestinal symptoms if ingested, such as nausea and stomach pains. It is also dangerous for animals, with documented cases of wildlife fatalities attributable to cyanobacterial toxins in various countries.

Authorities have mentioned that while not all cyanobacteria blooms are toxic, identification of their danger level cannot be determined by mere visual inspection. Consequently, the public is advised to exercise caution where water discolouration is apparent and to keep updated through the Main Sanitary Inspectorate’s information service for the status of specific bathing areas.

Experts noted that cyanobacterial presence in the Baltic can fluctuate significantly. Weather changes such as wind and rain can dissipate blooms as swiftly as they form. As highlighted by Zbigniew Zawadzki, spokesperson for the Gdańsk Sanitary and Epidemiological Station, a significant weather change could make the waters safe again just as quickly.
