5. Scombroid Food Poisoning
Unless you are getting your sushi fish straight out of the ocean, you have a high risk of getting scombroid food poisoning. Approximately 38% of seafood-related food poisoning cases are scombroid food poisonings.
When the fish is not preserved properly, it begins to rot and releases a chemical known as histamine. It causes allergic reaction including rash, headache, dizziness, flushing, and sweating. A serious reaction can even lead to anaphylaxis.
