Scombrotoxin can be found in which of the following?

Scombrotoxin is a type of histamine poisoning that can occur when certain types of fish, particularly those in the scombridae family such as tuna and mackerel, are not stored at the correct temperatures. If these fish are subjected to temperature abuse—meaning they are allowed to stay in the temperature danger zone (typically between 41°F and 135°F) for an extended period—bacteria can produce histamine, leading to scombrotoxin formation. This toxin can cause foodborne illness when consumed.

Understanding the specific conditions that lead to scombrotoxin formation helps emphasize the importance of temperature control for seafood. Proper handling, storage, and prompt refrigeration of fish are crucial to preventing the onset of this toxin. The other options involve other types of food safety issues but do not relate to the specific conditions that lead to scombrotoxin production.
