Poisoning can result from the ingestion of shellfish contaminated with phycotoxins. Various types of poisoning may occur, each of which is caused by a toxin (or group of toxins) from a particular alga. Classically, the mouse bioassay has been used to detect shellfish toxins, but there is pressure, both ethical and regulatory, to move away from this. A number of techniques have been developed to replace the bioassay, including immunoassay, chromatography, pharmacological assay and tissue-culture tests. All have advantages and limitations. These methods and their potential are reviewed. |
