Which of the following symptoms is associated with amnesic shellfish poisoning?

Amnesic shellfish poisoning (ASP) is caused by the consumption of shellfish that have accumulated toxins produced by certain algae, specifically domoic acid. A hallmark symptom of this type of poisoning is memory loss, which is directly related to the neurotoxic effects of the domoic acid on the brain. This substance can lead to irreversible memory impairment and acute neurological symptoms, making memory loss a distinctive and critical symptom of ASP.

While symptoms such as rash, fever, and weight gain are associated with other health conditions or types of poisoning, they do not characterize amnesic shellfish poisoning. Understanding the specific symptoms associated with foodborne illnesses is vital for effective diagnosis and treatment, highlighting the importance of recognizing memory loss as a key indicator in cases of ASP.
