Consumption of shellfish contaminated with algal toxins produced by marine dinoflagellates can lead to diarrhetic shellfish poisoning (DSP). UK legislation necessitates toxin detection by mouse bioassay but this method is non-specific and lacks sensitivity. As an alternative method, an HPLC technique has been optimized, with detection limits of 0.26 micrograms of toxin/g of shellfish hepatopancreas for both Okadaic Acid (OA) and Dinophysistoxin-1 (DTX-1). A colorimetric protein phosphatase inhibition (PPI) assay has also been optimized. This assay detects inhibition of protein phosphatase 1 (PPI gamma) by OA and DTX-1 with detection limits of 1.5 ng of total toxin/g of hepatopancreas. Contaminated shellfish from several European sources, the UK monitoring programmes and mussels associated with an outbreak of DSP poisoning in the UK, have been analyzed and assessed using the two alternative methods and a commercially available enzyme-linked immunosorbent assay (ELISA) kit. The results indicate that both the HPLC and PPI assays correlate well with each other and with the UK standard mouse bioassay. In contrast, and not withstanding its advantages of rapidity and ease, the ELISA kit did not accurately and consistently detect low toxin concentrations, although it may be useful as a screening tool.
