Three people in the northeastern United States have died from a rare flesh-eating bacteria this summer, Vibrio vulnificus, which can spread through warm, brackish water or the consumption of undercooked shellfish. New York Governor Kathy Hochul has urged residents to take precautions when swimming in warm, brackish water or eating raw shellfish, and the Centers for Disease Control and Prevention recommends that people with weakened immune systems avoid eating raw shellfish and wear protective clothing when handling it.
