Falmouth, MA Confirms Rare Vibrio vulnificus Case Linked to Swimming at Old Silver Beach

On August 12, 2025, Falmouth health officials issued a public awareness notice following a confirmed case of Vibrio vulnificus infection in an older individual.

The case, reported on August 8, 2025, involved exposure through swimming with an open wound at Old Silver Beach in Falmouth, Barnstable County, Massachusetts. The infection was investigated by Barnstable County disease investigators.

No beach advisory or closure was issued for Old Silver Beach, and Falmouth beaches have reported no closures in 2025 under state bathing water monitoring for fecal bacteria. Officials noted that there is no routine monitoring for Vibrio vulnificus in bathing waters.

Scott McGann, Health Agent for the Town of Falmouth, stated: “Cape Cod’s beaches are an important part of our economy, culture, and community. By taking a few simple precautions, residents and visitors, and particularly anyone who is vulnerable or immunocompromised, can continue to enjoy them safely.”

The release highlighted that most U.S. cases occur in Gulf Coast states, but rare Northeast cases are noted, with trends potentially linked to warming ocean temperatures. In Massachusetts, reported cases have been associated only with wound exposures from swimming, not local shellfish consumption.
