                                The CDC reports that Vibrio vulnificus infections in high-risk individuals, such as those with iron overload, are fatal approximately 50% of the time, providing a stark answer to why people with iron overload can't eat raw fish. The primary danger lies not just in the fish's iron content but in a specific, iron-loving bacterium that raw seafood can carry.
