Diarrheal shellfish poisoning
From Wikipedia, the free encyclopedia
Diarrheal shellfish poisoning (DSP) is one of the 4 recognised symptom types of shellfish poisoning, the others being paralytic, neurological and amnesic poisoning.) As the name suggests, this syndrome manifests itself as diarrhoea, although nausea, vomiting and cramps are all common too (though most diarrhoea cases, regardless of cause, seem to have the exact same set of symptoms, as diarrhoea is usually the body's effort to avoid absorbing water in the intestines, to flush out any micro-organisms that may have been ingested, and this causes the other symptoms as unfortunate side-effects of the body's efforts to cleanse itself.) DSP and its symptoms usually set in within about half an hour of ingesting infected shellfish, and last for about one day. As no life-threatening symptoms generally emerge from this, no fatalities from DSP have ever been recorded.
