A raw bar in NYC serves raw oysters. A customer with liver disease becomes severely ill. Which pathogen associated with raw shellfish is especially dangerous to this high-risk customer?
a.Bacillus cereus
b.Vibrio vulnificus
c.Clostridium perfringens
d.Hepatitis A only
Explanation
Vibrio vulnificus is found in raw or undercooked shellfish, particularly oysters, and can cause life-threatening bloodstream infection in people with liver disease or weakened immunity. Control includes buying from approved sources, keeping shellstock cold, and advising high-risk guests via the consumer advisory. Perfringens and Bacillus cereus are tied to temperature-abused cooked foods, not raw oysters.
