Warming oceans may be boosting levels of dangerous bacteria in northern seas, possibly explaining why more people are getting sickened by tainted seafood and seawater, new research suggests.
"From long-term data, it is apparent that the level of these pathogens is rising in the ocean as a result of global warming," said study author Luigi Vezzulli. He is an associate professor with the department of earth, environmental and life sciences at the University of Genoa, in Italy.
At the moment, the threat to humans is still considered to be low. But Vezzulli said the germs in question, known as vibrios, pose a threat and must be monitored "in the light of ongoing climate change, especially in coastal areas most heavily affected by ocean warming."
