Marine toxins are a significant concern because they can lead to various health issues when contaminated seafood is ingested. For example, saxitoxins associated with PSTs can cause neurological symptoms ranging from tingling sensations to paralysis and even death in severe cases. DSTs can lead to gastrointestinal symptoms, while ASTs may result in memory loss and brain damage. Ciguatoxins, which are not destroyed by cooking, can cause nausea, vomiting, and neurological disturbances.
