Scombrotoxin is described as which of the following?

• A. A bacterium in shellfish
• B. Scombrotoxin
• C. A sanitizing chemical
• D. A shellfish toxin

Answer: (B)

Scombrotoxin is the toxin itself that can form in certain fish when they’re not stored properly. Bacteria in the fish convert histidine in the fish muscle into histamine, creating this toxin. It’s not a bacterium, and it isn’t a sanitizing chemical. Cooking won’t reliably destroy it because histamine is heat-stable, so prevention relies on keeping fish cold and handling it correctly to stop toxin formation. That’s why describing scombrotoxin as the toxin itself is the best choice.
