Paralytic shellfish poisons (PSP) are the toxins responsible for acute and often fatal poisonings caused by the consumption of certain shellfish. The phenomenon has been known since prehistoric times. A thorough docuinen tation of the incidents can be found in HALSTEAD’S treatise on poisonousmarine organisms (7).

Neurology, 1990
We report serial electrophysiologic observations in a patient with acute bulbar and respiratory paralysis following ingestion of saxitoxin-contaminated clams. Prolonged distal motor and sensory latencies, slowed conduction velocities, and moderately diminished amplitudes were present at the outset. All values returned to normal over 5 days.

Paralytic shellfish poisoning: clinical and electrophysiological observations
Journal of Neurology, 1998In paralytic shellfish poisoning a mollusc contaminated with a toxin (saxitoxin) causes a potentially lethal disease, clinically characterised by gastrointestinal and neurological symptoms, of which possible respiratory depression is the most serious. The toxin acts by blocking the sodium channels. We report 9 Portuguese patients with this disease. The

Analysis of paralytic shellfish poisons by capillary electrophoresis
Journal of Chromatography A, 1991A capillary electrophoresis (CE) method with UV detection is described for the separation and determination of underivatized toxins associated with paralytic shellfish poisoning (PSP). Confirmation of the electrophoretic peaks was facilitated by mass spectrometric (MS) detection using an ionspray CE-MS interface and by high-performance liquid ...

Proficiency studies on the determination of paralytic shellfish poisoning toxins in shellfish
Food Additives & Contaminants, 2004Paralytic shellfish poisoning toxins are produced by dinoflagellates. Shellfish filtering these unicellular algae will accumulate the toxins and pose a health risk when consumed by man. In the European Union, paralytic shellfish poisoning toxins in bivalve molluscs are regulated at a maximum content of 80 microg/100 g (91/492/EEC).

Paralytic Shellfish Poisoning and Saxitoxin
1971During the past 200 years or more, medical records from various parts of the world have reported sporadic outbreaks of poisoning in humans following the ingestion of shellfish. This type of poisoning, termed shellfish or mussel poisoning, results in death or a temporary incapacitating illness that lasts a day or two.

Public Health Significance of Paralytic Shellfish Poison
1961Publisher Summary Widespread distribution of poisonous shellfish products would present a hazard to every shellfish consumer, and prevention depends primarily on identification of poisonous shellfish by laboratory assay methods before they reach the consumer.

BIOLOGICAL CAUSES AND EFFECTS OF PARALYTIC SHELLFISH POISONING
The Lancet, 1968Abstract The outbreak of shellfish poisoning in North-East England in May and June, 1968, was preceded by a number of biological events which can be related to profuse multiplication of dinoflagellates off the Northumbrian coast. One early pertinent event was the finding of dead sand-eels which could have ingested a toxin by feeding on marine fauna ...
