How do I get rid of Scombrotoxin?
Freezing may inactivate some of the enzyme- forming bacteria. Both the enzyme and the bacteria can be inactivated by cooking. However, once histamine is produced, it cannot be eliminated by heat (including retorting) or freezing.

Where does saxitoxin come from?
Saxitoxin is produced by the dinoflagellates Gonyaulax, Alexandrium, Gymnodinium, and Pyrodinium. Similar to tetrodotoxin, saxitoxin binds to voltage-gated sodium channels within cell membranes, inhibiting membrane depolarization and blocking proliferation of action potentials.
How does saxitoxin cause paralysis?
Saxitoxin, like CTX and tetrodotoxin, causes paralysis by blocking sodium channels in nerve cell membranes. It is 50 times more potent than curare. Saxitoxin and other toxins that cause PSP are heat stable and are not destroyed by normal cooking procedures, marinating, or freezing.
How is saxitoxin absorbed?
