Surveys were carried out between 2007 and 2009 to determine the aflatoxin B1 content of 3345 commercial Turkish foodstuffs supplied by producers for testing for their own purposes or for export certification. To simplify the reporting of data, foods were categorized as: 1, high sugar products with nuts; 2, nuts and seeds; 3, spices; 4, grain; 5, cocoa products; 6, dried fruit and vegetables; 7, processed cereal products; 8, tea; and 9, baby food and infant formula. Aflatoxin analysis was carried out by high-performance liquid chromatography with fluorescence detection after immunoaffinity column clean-up, with a recoveries ranging from 91% to 99%, depending on the matrix. Of the 3345 samples analysed, 94% contained aflatoxin B1 below the European Union limit of 2 µg kg(-1), which applies to nuts, dried fruit, and cereals products. The 6% of the 206 contaminated samples were mainly nuts and spices. For pistachios, 24%, 38%, and 42% of the totals of 207, 182, and 24 samples tested for 2007, 2008 and 2009, respectively, were above 2 µg kg(-1), with 50 samples containing aflatoxin B1 at levels ranging from 10 to 477 µg kg(-1).
在2007年至2009年期间开展了多项调查，以测定3345种土耳其商业食品的黄曲霉毒素B1含量，这些食品由生产商提供，用于其自身检测目的或出口认证检测。为简化数据报告，食品被分类如下：1. 含坚果的高糖产品；2. 坚果和种子；3. 香料；4. 谷物；5. 可可制品；6. 干果蔬；7. 加工谷物产品；8. 茶；9. 婴儿食品和婴儿配方奶粉。黄曲霉毒素分析采用免疫亲和柱净化后高效液相色谱荧光检测法，回收率根据基质不同在91%至99%之间。在分析的3345个样本中，94%的样本黄曲霉毒素B1含量低于欧盟适用于坚果、干果蔬和谷物产品的2 μg/kg限量。206个受污染样本中的6%主要是坚果和香料。对于开心果，在2007年、2008年和2009年分别检测的207个、182个和24个样本中，总计分别有24%、38%和42%的样本黄曲霉毒素B1含量高于2 μg/kg，有50个样本的黄曲霉毒素B1含量在10至477 μg/kg之间。
