The objective of this study was the estimation of the content of 13 mycotoxins (diacetoxyscirpenol, T-2 toxin, HT-2 toxin, nivalenol, deoxynivalenol, 3-acetyldeoxynivalenol, fusarenone X, aflatoxin B1, aflatoxin B2, aflatoxin G1, aflatoxin G2, ochratoxin A, and zearalenone) in various products from the eastern part of Poland. The content of mycotoxins in the analysed samples was assayed using the extraction method combined with HPLC-MS/MS analysis. We found mycotoxins in 25 of the 92 samples tested (27%). Contamination with mycotoxins was noted most frequently in samples of cereals – 56% – and also in samples of flour and cocoa, in which a content of mycotoxins was noted in 24 and 16% of the samples, respectively. The most frequently identified were the following – deoxynivalenol detected in 18 samples (72%), zearalenone detected in eight samples (32%), toxin HT-2 detected in four samples (16%), ochratoxin A identified in three samples (12%), and toxin T-2 detected in one sample (4%). In one analysed sample of mixed flour and in one analysed sample of wheat and rye flour, the maximum allowable concentration was exceeded in the case of two identified mycotoxins – deoxynivalenol (2,250 μg/kg) and ochratoxin A (15.6 and 17.1 μg/kg).

波兰东部部分农产品和商业产品中霉菌毒素的存在

本研究的目的是估计 13 种真​​菌毒素(二乙酰氧基scirpenol、T-2 毒素、HT-2 毒素、雪腐镰刀菌烯醇、脱氧雪腐镰刀菌烯醇、3-乙酰脱氧雪腐镰刀菌烯醇、镰刀菌烯酮 X、黄曲霉毒素 B1、黄曲霉毒素 B2、黄曲霉毒素 G1、黄曲霉毒素 G2、赭曲霉毒素 A 和玉米赤霉烯酮)存在于波兰东部的各种产品中。使用提取方法结合 HPLC-MS/MS 分析法测定分析样品中真菌毒素的含量。我们在测试的 92 个样本中的 25 个(27%)中发现了霉菌毒素。真菌毒素污染在谷物样品中最为常见(56%),在面粉和可可样品中也最常见,其中分别有 24% 和 16% 的样品含有霉菌毒素。最常见的是以下物质——在 18 个样本中检测到脱氧雪腐镰刀菌烯醇 (72%),8 个样品中检测到玉米赤霉烯酮 (32%),4 个样品中检测到毒素 HT-2 (16%),3 个样品中检测到赭曲霉毒素 A (12%),1 个样品中检测到毒素 T-2 (4%)。在一份混合面粉分析样本和一份小麦和黑麦面粉分析样本中,两种已鉴定的真菌毒素——脱氧雪腐镰刀菌烯醇 (2,250 μg/kg) 和赭曲霉毒素 A(15.6 和 17.1 μg/kg)超过了最大允许浓度.
