2001年开始监测加泰罗尼亚海岸贝类中的失忆性贝类中毒毒素。在2008年之前进行的任何分析中均未检出ASP毒素。2008年1月22日，在唐菖蒲中检测到软骨藻酸（DA）（0.5 mg kg（-1）），并通过快速分辨液相色谱-串联质谱法（0.6 mg kg（-1））进行了确认。从2008年1月至2011年12月，共分析了974个贝类样本，涵盖了所有加泰罗尼亚生产区和最重要的上市品种。在23.8%的样品中检测到DA，并且每个月在所有地区和所有物种中记录，除了Ostrea edulis，尽管具有DA的样品的百分比和DA含量在样品之间变化很大。DA两次超过20 mg kg（-1）的监管水平：2008年2月采集的Callista chione和D. 2010年4月取样的trunculus。2009年，Bolinus brandaris中的DA含量保持稳定，并在几个月内接近4.5 mg kg（-1）。贻贝galloprovincialis，太平洋牡蛎，和蛤仔属。提出了非常低的DA浓度在埃布罗三角洲海湾，尽管113警报情况下，根据伪菱形藻属。丰度和分析的贝类样本数量很多。加泰罗尼亚贝类中DA的来源仍然未知。
Monitoring of amnesic shellfish poisoning (ASP) toxins in shellfish from the Catalan coast started in 2001. No ASP toxins were detected in any of the analyses performed before 2008. On 22 January 2008, domoic acid (DA) was detected in Donax trunculus (0.5 mg kg(-1)) and confirmed by rapid resolution liquid chromatography-tandem mass spectrometry (0.6 mg kg(-1)). A total of 974 shellfish samples were analyzed from January 2008 to December 2011, covering all the Catalan production areas and the most important marketed species. DA was detected in 23.8 % of the samples and was recorded every month in all areas and all species, except Ostrea edulis, although the percentage of samples with DA and DA content varied widely among samples. DA exceeded the regulatory level of 20 mg kg(-1) twice: in Callista chione sampled on February 2008 and in D. trunculus sampled on April 2010. DA content in Bolinus brandaris appeared constant and close to 4.5 mg kg(-1) for months in 2009. Mytilus galloprovincialis, Crassostrea gigas, and Ruditapes sp. presented very low concentrations of DA in the Ebro Delta bays, despite 113 alert situations according to Pseudo-nitzschia spp. abundances and the high number of shellfish samples analyzed. The origin of DA in Catalan shellfish remains unknown.
