Episode 24: No Boat Big Enough - The Rise of Vibrio Vulnificus
In this gripping episode, we dive into the world of Vibrio vulnificus—a flesh-eating bacterium once confined to warm southern waters, now making deadly appearances from Florida to Cape Cod.
We begin with real-life cases from the 2025 surge across the U.S., then uncover the science behind this microscopic killer: how it invades, how it spreads, and why it’s rising globally. From wound infections to raw oysters, climate change to coastal vulnerability—this is a public health warning.
Because with Vibrio vulnificus, a bigger boat won’t help.
