A customer becomes flushed, dizzy, and develops a rash within minutes of eating tuna that was stored improperly. This is most likely which type of toxin illness?

Explanation

Scombroid poisoning is caused by histamine that forms when fish like tuna, mahi-mahi, and mackerel are time-temperature abused; symptoms appear rapidly and include flushing and rash. The histamine is not destroyed by cooking, so cold storage is critical. Ciguatera comes from reef fish toxins and botulism causes neurological paralysis.
