We report the first detection of tetrodotoxins (TTX) in European bivalve shellfish. We demonstrate that TTX is present within the temperate waters of the United Kingdom, along the English Channel, and can accumulate in filter-feeding molluscs. The toxin is heat-stable and thus it cannot be eliminated during cooking. While quantified concentrations were low in comparison to published minimum lethal doses for humans, the results demonstrate that the risk to shellfish consumers should not be discarded.
我们首次在欧洲双壳贝类中检测到河豚毒素 (TTX)。我们证明 TTX 存在于英国的温带水域,沿英吉利海峡,并可以在滤食性软体动物中积累。该毒素耐热,因此在烹饪过程中无法消除。尽管与已发表的人类最低致死剂量相比,定量浓度较低,但结果表明不应忽视贝类消费者的风险。
