Health concerns
Anchovies can concentrate domoic acid in their gut which causes amnesic shellfish poisoning in humans when eaten whole.[8] If suspected, medical attention should be sought.

Amnesic shellfish poisoning (ASP) is a human illness caused by consumption of the marine biotoxin called domoic acid.[1] This toxin is produced naturally by marine diatoms belonging to the genus Pseudo-nitzschia and the species Nitzschia navis-varingica. When accumulated in high concentrations by shellfish during filter feeding, domoic acid can then be passed on to humans via consumption of the contaminated shellfish.[2][3][4][5][6][7][8][9]
Although human illness due to domoic acid has only been associated with shellfish, the toxin can bioaccumulate in many marine organisms that consume phytoplankton, such as anchovies, and sardines. Intoxication by domoic acid in non-human organisms is frequently referred to as "domoic acid poisoning" or "DAP". In mammals, including humans, domoic acid acts as a neurotoxin, causing permanent short-term memory loss, brain damage, and death in severe cases.

In the brain, domoic acid especially damages the hippocampus and amygdaloid nucleus.[1] It damages the neurons by activating AMPA and kainate receptors, causing an influx of calcium. Although calcium flowing into cells is a normal event, the uncontrolled increase of calcium causes the cell to degenerate. See reviews by Ramsdell (2007) [10] and Pulido (2008).[11]
Gastrointestinal symptoms can appear 24 hours after ingestion of affected molluscs. They may include vomiting, nausea, diarrhea, abdominal cramps and haemorrhagic gastritis. In more severe cases, neurological symptoms can take several hours or up to three days to develop. These include headache, dizziness, disorientation, vision disturbances, loss of short-term memory, motor weakness, seizures, profuse respiratory secretions, hiccoughs, unstable blood pressure, cardiac arrhythmia and coma.
People poisoned with very high doses of the toxin or displaying risk factors such as old age and renal failure can die. Death has occurred in 4 of 107 confirmed cases. In a few cases, permanent sequelae included short-term memory loss and peripheral polyneuropathy.
There is no known antidote available for domoic acid, so if symptoms fit the description, it is advised to go quickly to a hospital. Cooking or freezing affected fish or shellfish tissue does not lessen the toxicity. New research has found that domoic acid is a heat resistant and very stable toxin which can damage kidneys at concentrations that are 100 times lower than what causes neurological effects.
