在英国，人类通过食用贝类而中毒的可能性是存在的，贝类本身也食用了产生生物毒素的海洋浮游植物。毒素在贝类肉内生物积累，使它们达到有害浓度。通过监测方案评估潜在有害浮游植物和贝类肉毒性的存在，这种威胁在很大程度上得到缓解。然而，英国的医学界对生物毒素衍生的贝类毒性的潜在性仍然相对无知，这阻碍了对社区健康影响的幅度、频率和严重程度的量化，也阻碍了对最近发现的毒素的医学意义的量化。虽然目前的致病物种及其毒素的特点相对较好，但仍然缺乏对有害浮游植物时空外观的因素的了解。贝类水产养殖的扩张可能在世界范围内和英国。为了加强风险评估，需要更好地了解有害浮游植物如何与其环境相互作用，以促进我们观察到的零星有害水华。
The potential for poisoning of humans through their consumption of shellfish which have themselves consumed biotoxin producing marine phytoplankton exists in the UK. Toxins are bio-accumulated within the shellfish flesh allowing them to reach harmful concentrations. This threat is in most part mitigated by monitoring programmes that assess both the presence of potentially harmful phytoplankton and shellfish flesh toxicity. However, the medical profession in the UK remains relatively ignorant of the potential for biotoxin derived shellfish toxicity, preventing quantification of magnitude, frequency, and severity of health effects in the community or the medical significance of more recently discovered toxins. While the current causative species and their toxins are relatively well characterised there remains a lack of understanding of the factors governing the temporal and spatial appearance of harmful phytoplankton. Expansion of shellfish aquaculture is likely both worldwide and in the UK. Better understanding of how harmful phytoplankton interact with their environment to promote the sporadic harmful blooms that we observe is required to underpin risk assessments.
