Abstract
A study was conducted to aid the interpretation of data generated by parallel testing of the qualitative Jellett Rapid Test (JRT) and the mouse bioassay (MBA) for detection of paralytic shellfish poisoning (PSP) toxins within the UK statutory shellfish biotoxin monitoring programme. A selection of stored sample extracts subjected to testing by MBA and/or JRT were further analysed by liquid chromatography with fluorescence detection (LC–FLD) to provide additional information on the concentrations of PSP toxins and toxin profiles. Results, from this study, demonstrate the potential of the JRT to effectively screen out PSP toxin negative shellfish samples and samples containing low concentrations of toxins from UK monitoring programmes. Additionally, data generated using LC–FLD highlights the potential of introducing alternative analytical techniques to completely replace the requirement for the MBA.
