Abalone & Food Poisoning

Ciguatera Poisoning

• During the warm months, saltwater mollusks are subject to red tide, according to Medline Plus. Algal bloom produces poisonous organisms, dinoflagellates, which are eaten by the mollusks. Dinoflagellates make ciguatoxin, which is harmful to humans if ingested.

Types to Avoid

• The viscera of abalone in warm tropical waters can harbor this poisonous substance. No matter how well the shellfish is cooked, if it contains heat-stable ciguatoxin, you will be poisoned.

Symptoms

After these symptoms, you may experience bizarre sensations, like the feeling your teeth are loose; confusing hot and cold temperatures (ice could feel hot, fire could feel cold); or a metallic taste in your mouth.

Warning
