Seasonal Vibrio Risk Prompts Caution in Brunswick County Waters

State health officials warn that warming coastal conditions are increasing the likelihood of wound infections linked to naturally occurring bacteria.

Brunswick County, NC — Residents and visitors are urged to use caution around warm coastal waters as state health officials highlight the seasonal risk of Vibrio infections, the naturally occurring bacteria sometimes referred to as “flesh‑eating.”

The North Carolina Department of Health and Human Services (NCDHHS) confirms that Vibrio bacteria are commonly found in brackish coastal environments, including the Intracoastal Waterway, tidal creeks, sounds, and river mouths. The bacteria become more active as water temperatures rise above 60 degrees; a level typically reached in late spring and summer along the southeastern coast.

While Vibrio is less common in the open Atlantic surf zone, it thrives in shallow, warm, mixed‑salt waters. Health officials emphasize that the bacteria do not live inside fish meat, but can be present on oyster shells, fish spines, crab claws, and in raw shellfish — especially oysters.

Most severe Vibrio infections occur when the bacteria enter the body through a break in the skin.

Higher‑risk exposures include:

Open cuts or scrapes
Fresh tattoos
Punctures from shells or fish spines
Cracked skin on hands or feet
Handling raw seafood with small wounds

Health officials urge anyone who develops symptoms within hours of water exposure or seafood handling to seek immediate medical care.

Warning signs include:

Rapidly spreading redness or swelling around a wound
Skin that becomes warm, tender, or painful
Severe pain that worsens quickly
Blisters or skin discoloration
Fever, chills, nausea, or sudden fatigue

Early treatment is critical, as Vibrio infections can progress quickly and delaying care increases the risk of serious complications.

To reduce risk:

Avoid exposing open wounds to brackish water
Wear water shoes and gloves when fishing or handling shellfish
Wash cuts immediately with soap and clean water
Avoid eating raw oysters or raw shellfish
Seek prompt medical attention if symptoms develop after exposure

State surveillance data show that Vibrio infections in North Carolina have increased over the past several years, a trend health officials link to warming coastal waters and longer warm‑water seasons.
