What are the symptoms of amnesic shellfish poisoning?
Amnesic shellfish poisoning can be very serious.
It usually starts with digestive symptoms such as an upset stomach, cramps, throwing up or diarrhea. These symptoms usually appear in the first few hours after eating contaminated shellfish.
It can then move on to symptoms affecting the nervous system within the next three days. These can include headache, confusion, dizziness, disorientation and memory loss. This memory loss may remain, even after the other symptoms go away.
In severe cases, a person may feel weak, have seizures, become paralyzed or even die.
