What symptom can indicate amnesic shellfish poisoning (ASP)?

Memory loss is a primary symptom that can indicate amnesic shellfish poisoning (ASP), which is caused by consuming shellfish that have accumulated a toxin called domoic acid. This toxin, produced by certain algae, can lead to significant neurological effects, including short-term memory loss, confusion, and disorientation.

Unlike the other symptoms listed, memory loss is distinctive for ASP. While symptoms such as fever, diarrhea, and cramps may occur with various other foodborne illnesses, memory impairment specifically indicates the neurological impact of the toxin associated with amnesic shellfish poisoning. Recognizing memory loss as a symptom is crucial for identifying cases of ASP early and addressing the health risks associated with the consumption of contaminated shellfish.
