Since the very first tar balls began rolling onshore along the Gulf of Mexico following 2010’s Deepwater Horizon oilrig explosion and subsequent underwater oil geyser, the oil industry told us to relax because those tar balls were completely harmless.

But as we approach the two year anniversary of the disaster, new studies have confirmed that the tar balls we’re seeing along our beaches contain bacteria that are capable of killing human beings.

The new study, conducted by scientists at Auburn University, confirmed the presence of a bacteria called Vibrio vulnificus.

...The Centers for Disease Control says the following regarding Vibrio vulnificus:

Wound infections may start as redness and swelling at the site of the wound that then can progress to affect the whole body.

V. vulnificus typically causes a severe and life-threatening illness characterized by fever and chills, decreased blood pressure (septic shock), and blood-tinged blistering skin lesions (hemorrhagic bullae).

Overall, V. vulnificus infections are fatal about 40% of the time. Wound infections with V. vulnificus are fatal about 20% of the time, and aggressive surgical treatment can prevent death.

Persons who have immunocompromising conditions and especially persons with chronic liver disease are particularly at risk for V. vulnificus infection when they eat raw or undercooked seafood, particularly shellfish harvested from the Gulf of Mexico, or if they bathe a cut or scrape in marine waters.

About three-quarters of patients with V. vulnificus infections have known underlying hepatic disease or other immunocompromising illness.

Otherwise healthy persons are at much lower risk of V. vulnificus infection.
