Evidence of the presence of okadaic acid (OA) and its monthly fluctuations are reported for the first time in Mytilus galloprovincialis samples collected from June 2005 to May 2006 in the Bizerte Lagoon. All of the samples with the exception of those taken in August 2005 were found to be contaminated. The level of OA in mussels exceeded the regulatory limit of DSP toxins (16 microg OA/100 g mussel meat) within the European Union (2002) in only two cases: in January and February, 2006 with 31.85 +/- 3.06, and 18.86 +/- 1.88 microg OA/100 g mussel meat respectively. During the investigative period, potentially toxic dinoflagellates were observed. The results reported here, although based on limited sampling, demonstrate for the first time the existence of a risk to public health from diarrheic shellfish poisoning in cultivated bivalve mollusc in Tunisia.
首次报道了2005年6月至2006年5月在比塞大泻湖采集的加利福尼亚贻贝样本中存在冈田酸(OA)及其月度波动情况。除2005年8月采集的样本外,所有样本均被发现受到污染。贻贝中OA的含量仅在两种情况下超过了欧盟(2002年)规定的腹泻性贝类毒素监管限量(16微克OA/100克贻贝肉):2006年1月和2月,分别为31.85±3.06和18.86±1.88微克OA/100克贻贝肉。在调查期间,观察到了潜在有毒的甲藻。此处报告的结果虽然基于有限的采样,但首次证明了突尼斯养殖双壳贝类中腹泻性贝类中毒对公众健康存在风险。
