Red flag on beaches because of bacteria in Baltic Sea

The Main Sanitary Inspectorate (GIS) announced the ban of swimming on more than a dozen beaches in the Polish seaside, due to the presence of cyanobacteria in the water.

GIS announced on its website that it is forbidden to swim on 11 beaches in the Tricity (Gdańsk, Sopot, Gdynia). Moreover, the ban has also been introduced in the town of Darłowo in the western part of the coast is also closed, but this time because of the Escherichia coli bacteria, as well as in the town of Mikoszewo near the Vistula estuary.

The decision to forbid swimming is always made by lifeguards, who are constantly monitoring the water. If such a decision is made, the red flag is hoisted.

Maps with the current status of beaches at the Polish seaside can be found on the website of GIS.

The sanitary inspection emphasises that the situation can change “any time.” The wind and currents can move the concentrations of cyanobacteria away from the beaches.

Swimming in water polluted with cyanobacteria can result with reactions of the body, such as rash, and swallowing such water can cause problems of the digestive system, such as diarrhoea, nausea and stomach pain.
