RASFF-foodborne outbreak suspected (scombroid syndrome) to be caused by frozen salifish (Istiophorus albicans) from Spain in Italy.
Scombroid poisoning is a disease due to the ingestion of contaminated food (mainly fish). In scombroid poisoning, bacteria have grown during improper storage of the dark meat of the fish and the bacteria produce scombroid toxin. Scombroid toxin, or poison, is probably a combination of histamine and histamine-like chemicals. The toxin or poison does not affect everyone who ingests it.
No test is 100% reliable for assessing fish for this toxin or poison. Cooking kills the bacteria, but toxins remain in the tissues and can be absorbed after the food is ingested.
Susceptible fish include albacore, amberjack, anchovy, Australian salmon, bluefish, bonito, kahawai, herring, mackerel, mahi-mahi, needlefish, saury, sardine, skipjack, wahoo, and yellowfin tuna. Other fish and foods probably will be added to the list if testing systems for the poison improve. Affected fish may have a metallic or peppery taste.
