TOXIC SUBSTANCES IN FOOD
Metals, Hydrocarbons, N-Nitroso Substances and Mycotoxins
TOXINS IN FISH, SHELLFISH, AND TURTLES ()()() are neurotoxins (anticholinesterase
Ciguatera, scaritoxin, and maitotoxin
is originally made by dinoflagellates and biotransformed into the active form by fish; after consumption, humans experience gastrointestinal disorders, neurologic symptoms, or death.
Ciguatera
Is produced by the zoanthid so coral of the genus Palythoa, and fish, crabs, and polychaete worms, living in close association with or eating this mass, may become contaminated with
Palytoxin
Produced by dinoflagellates (Gymnodinium breve) and concentrated in filter-feeding organisms, bind to voltagedependent sodium channels.
BREVETOXINS
Is found in shellfish feeding on dinoflagellates; blockade of ion channels in neural transmission at neuromuscular junctions leads to paresthesia and muscular weakness.
Saxitoxin
Is also found in shellfish; an analog of the neurotransmitter glutamine, it leads to damage to the hippocampus and other brain areas, causing various neurologic symptoms.
Domoic acid
s consumed by humans by eating improperly prepared pufferfish. It causes paralysis of the central nervous system and peripheral nerves by blocking the movement of all monovalent cations, leading to muscular paralysis, respiratory distress, and sometimes death
TETRODOTOXIN
Is found in sea turtles and causes necrosis of the myocardium and pulmonary edema.
CHELONITOXIN
Escolar (Lepidocybium avobrunneum) and Oil fish or Cocco (Ruvettus pretiosus) contain a strong (), which when consumed can cause diarrhea known as gempylid fish poisoning, gempylotoxism, or keriorrhea.
purgative oil
found in the salivary glands of Buccinum, Busycon, or Neptunia spp., a type of whelk or sea snail that is distributed in temperate and tropic waters
Tetramine
