Vibrio vulnificus risk on Croatia's Adriatic coast remains low despite summer heat

Media reports of "flesh‑eating" bacteria prompting beach closures in Spain have sparked public concern across the Mediterranean. Experts clarify that the bacterium Vibrio vulnificus, a natural inhabitant of warm, shallow, brackish waters, is present in the region but infections are rare and usually require open wounds or consumption of raw seafood.

In Croatia, microbiologists from the Institute of Oceanography and Fisheries in Split note that regular monitoring focuses on Escherichia coli and intestinal enterococci, not Vibrio species. They explain that the Adriatic water quality has been rated excellent for years, with about 97 % of beaches meeting EU standards. While rising sea temperatures could create more favorable conditions for Vibrio growth, current data show no significant threat to swimmers, and health authorities consider the risk on the Croatian coast to be minimal.

The experts stress that vulnerable individuals—those with liver disease, weakened immunity, diabetes, the elderly, or open skin injuries—should take precautions, but there is no basis for widespread panic.
