The bacterial content of the sea water is measured eyery day, published in the local paper and announced on the local radio - no one as far as I know has ever become ill after swimming in the Gulf of Trieste.
In the northern part of the Adriatic the sea is clean and healthy and it supports a lot of sea life.
In Trieste we have a WWF marine reserve. Grado, only a few miles away, which has the record of the cleanest sea in Italy.
