The Massachusetts Department of Public Health has issued a warning about a rare bacterial infection linked to Buzzards Bay beach, prompting residents with wounds to take precautions around coastal waters and be vigilant about handling and consuming raw seafood. The infection, known as Vibrio vulnificus, is more common in beaches on the Gulf Coast but can also occur along the Atlantic coast.
According to officials, heat waves and above-average water surface temperatures create favorable conditions for Vibrio bacteria to grow, making May through October peak season. People with open wounds who spend time in the water or consume contaminated shellfish are at risk of developing an infection when the bacteria enter the body.
In Massachusetts, 71 confirmed and probable cases from various Vibrio species have been reported this year, with 30% of those individuals hospitalized. Public health officials recommend that people with wounds cover them with a waterproof bandage, stay out of coastal waters, immediately wash wounds after contact, wear protective clothing and shoes, and be vigilant about handling raw seafood.
Individuals who handle raw seafood should immediately wash their hands to avoid cross-contamination, while those with open wounds exposed to warm coastal waters should monitor their symptoms and seek medical care if they experience fever, chills, or other severe reactions. The infection can cause severe illness, including gastrointestinal issues and life-threatening conditions in vulnerable populations such as those with liver disease, cancer, diabetes, HIV, or thalassemia.
