Amnesic shellfish poisoning
Amnesic Shellfish Poisoning
Amnesic Shellfish Poisoning (ASP), also known as domoic acid poisoning (pronunciation: /æmˈniːzɪk ˈʃɛlfɪʃ ˈpɔɪzənɪŋ/), is a type of foodborne illness caused by the consumption of shellfish contaminated with domoic acid.
Etymology
The term "Amnesic Shellfish Poisoning" is derived from the primary symptom of this condition, which is amnesia, or memory loss. The term "domoic acid poisoning" refers to the specific toxin that causes this condition.
Symptoms
The symptoms of ASP can range from mild to severe and may include gastrointestinal issues such as vomiting, diarrhea, and abdominal cramps. Neurological symptoms can also occur, including confusion, memory loss, disorientation, and in severe cases, seizures and coma.
Causes
ASP is caused by the consumption of shellfish that have ingested the marine diatom Pseudo-nitzschia, which produces the neurotoxin domoic acid. Shellfish such as mussels, clams, oysters, and scallops can accumulate high levels of this toxin without harm to themselves, but when consumed by humans, it can lead to ASP.
Treatment
There is no specific antidote for ASP. Treatment is supportive and focuses on managing symptoms. In severe cases, hospitalization may be required.
Prevention
Prevention of ASP involves monitoring of shellfish beds for the presence of domoic acid and avoiding the consumption of shellfish from affected areas.
