荷兰于 2014 年秋季对零售商店收集的样品进行了一项关于食品类别无花果干 (n = 14)、向日葵产品 (n = 24) 和番茄产品 (n = 43) 中链格孢毒素的调查。这项调查的发生数据证实了先前报告的 2013 年试点调查的数据，tenuazonic 酸是无花果干中普遍存在的链格孢毒素 (100% 的样本)，葵花籽（占样品的80%）和番茄制品（占样品的60%）浓度相对较高，无花果干中高达1728μg/kg，葵花籽中高达1350μg/kg。尽管向日葵种子和无花果中含有高浓度的丁脲酸，但荷兰人口不太可能受到关注。 27% 的番茄产品中检测到交链格醇，含量范围从 LOQ（2 μg/kg）到 26 μg/kg，而 7% 的番茄产品中存在交链格醇单甲醚。在最坏的情况下，食用这些产品可能会导致交链孢醇的暴露水平超过毒理学关注阈值（2.5 纳克/公斤体重/天）。七种链格孢毒素结合物均未检测到超过 2.5 μg/kg 的定量限 (LOQ)。 (C) 2016 Elsevier Ltd. 保留所有权利。
A survey on Alternaria toxins in the food categories dried figs (n = 14), sunflower products (n = 24) and tomato products (n = 43) was carried out in the Netherlands on samples collected in retail stores in autumn 2014. The occurrence data from this survey confirmed the previously reported data of a pilot survey in 2013, with tenuazonic acid being an ubiquitous Alternaria toxin in dried figs (100% of the samples), sunflower seeds (80% of the samples) and tomato products (60% of samples) at relatively high concentrations, up to 1728 mu g/kg in dried figs and 1350 mu g/kg in sunflower seeds. Despite the occurring of high concentrations of tenuazonic acid in sunflower seeds and figs, it is unlikely that the population in the Netherlands is exposed to levels of concern. Alternariol was detected in 27% of the tomato products ranging from LOQ (2 mu g/kg) up to 26 mu g/kg, while alternariol monomethyl ether was present in 7% of the tomato products. In the worst case situation, consumption of these products may result in exposure at levels above the threshold of toxicological concern of 2.5 ng/kg body weight/day for alternariol. None of seven conjugates of Alternaria toxins was detected above the limit of quantification (LOQ) of 2.5 mu g/kg. (C) 2016 Elsevier Ltd. All rights reserved.
