Clostridium botulinum type E has been demonstrated to have a particularly close association with which food category?

• A. Pork and pork products
• B. Cooked beef and gravy
• C. Fish and fish products
• D. Poultry and poultry products

Answer: (C)

Clostridium botulinum type E is most closely linked to fish and fish products because its ecology centers on marine environments, and this type tends to contaminate and produce toxin in fishy preparations stored in anaerobic, refrigerated conditions. Historical outbreaks have been tied to seafood—especially smoked, salted, or otherwise processed fish—where low acidity and vacuum or oil-rich environments allow toxin formation even at cooler temperatures. Other food categories, like pork, beef, or poultry products, are more commonly associated with other botulinum types, so they’re less typical sources for type E. That marine linkage is why fish and fish products are the best match.
