Massachusetts Officials Warn of Rare Bacteria in Coastal Waters

Massachusetts public health officials raised an alert on Wednesday regarding a rare and potentially dangerous bacteria found in the coastal waters of the state following an infection reported from a swimmer on Cape Cod.

The infection, caused by Vibrio vulnificus bacteria, was identified in an “older individual” who swam at Old Silver Beach in Falmouth while having an open wound, according to statements from health officials in Falmouth and Barnstable County.

Despite this incident, Old Silver Beach remains open. Officials have emphasized that infections from this type of bacteria are “extremely uncommon.”

Scott McGann, the Falmouth health agent, noted the importance of Cape Cod’s beaches to the local community and economy. He suggested that by taking a few precautions, especially for those who are vulnerable or immunocompromised, people can still enjoy these beaches safely.

Falmouth officials mentioned that there’s no effective way to monitor bathing waters for Vibrio bacteria.

State health authorities reported that, over the past few years, there have been seven confirmed cases of Vibrio vulnificus in Massachusetts, four of which likely occurred within the state.

Infections from this bacteria are, generally, more prevalent in the warmer waters along the Gulf Coast. Public health officials indicated that most infections result from consuming shellfish contaminated with Vibrio.

Though anyone can contract an infection, those with weakened immune systems, chronic illnesses, young children, and pregnant individuals are more susceptible to severe effects.

As stated by Public Health Commissioner Robbie Goldstein, Vibrio bacteria thrive in warm, saltwater environments along the Atlantic coast. The summer months, particularly May through October, are typically peak seasons for these bacteria. Open wounds can easily become infected when exposed to these waters or by consuming contaminated shellfish, leading to severe, sometimes life-threatening illnesses.

Some Vibrio infections can escalate into severe conditions like necrotizing fasciitis, a disease that destroys tissues around the infection site. Symptoms include fever, chills, vomiting, and diarrhea.

Health officials advised people with open wounds who have been in coastal waters to monitor for symptoms for up to seven days. They should seek medical attention if they experience fever, chills, low blood pressure, blistering skin lesions, or other signs of infection.

To mitigate the risk of infection, health authorities recommend staying out of warm coastal waters or using waterproof bandages over open wounds. It’s also advisable for those with injuries to avoid handling raw seafood and to wash wounds with soap and water after exposure to coastal waters or raw shellfish.
