"Flesh-eating" bacteria can spread in the Mediterranean

Tourists planning to enjoy the Mediterranean Sea this summer are being alerted to the presence of the flesh-eating bacterium Vibrio vulnificus. This dangerous microbe, which can cause a severe condition known as "bad wound fever," thrives in warm, brackish waters and poses a significant health risk.

The bacterium enters the body primarily through open wounds exposed to contaminated water or via the consumption of raw shellfish, particularly oysters. While not literally flesh-eating, Vibrio vulnificus destroys body tissue at an alarming rate, sometimes necessitating limb amputations within hours of the infection taking hold. It can also lead to life-threatening blood poisoning.

Experts note that rising sea temperatures, a direct consequence of climate change, are creating ideal conditions for the bacterium to flourish. The Mediterranean is warming at a rate significantly faster than the global average for oceans. This warming, coupled with changes in salinity, is altering the environment in favor of the bacteria. European Environment Agency data indicates that surface temperatures in European waters have risen four to seven times faster than the global average.

Increased bacterial density in the water, resulting from evaporation due to heat, further elevates the risk of exposure for the millions of tourists who visit the Mediterranean region annually. Health authorities advise caution, especially for individuals with open wounds, and recommend prompt medical attention if symptoms arise.
