The Florida Department of Health is warning residents of a strain of flesh-eating bacteria that has claimed dozens of lives every year since 2010.
The DOH says vibrio vulnificus is the naturally-occurring bacteria that lives in warm seawater. People get infected by eating contaminated food or have an open wound that is exposed to the water.
More than 120 people have died from the bacteria in Florida since 2008, with hundreds more cases reported that did not result in death.
The health department warns about eating raw oysters or other shellfish and make sure it is cooked thoroughly.
Officials advise residents and tourists with fresh cuts or scrapes to avoid the water. Also, those with chronic liver disease, kidney disease or a weakened immune system are urged to wear proper foot protection if going into the water.
