What happened

Flesh-eating bacteria sounds like the premise of a bad horror movie, but it’s a growing – and potentially fatal – threat to people in the U.S.

Why it matters

Vibrio vulnificus, a type of flesh-eating bacteria that thrives in warm seawater, is once again threatening the safety of beachgoers and raw shellfish enthusiasts.

Common ground

To date, Louisiana has reported nine cases, with five fatalities, and Florida has reported 14 cases, with two fatalities.

Perspective signals

The tension in the story is sharpened by Loaded Language, Appeal to Fear: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
