Mycotoxin Res. 2017 Aug;33(3):219-227. doi: 10.1007/s12550-017-0280-3. Epub 2017 May 9.
In this study, the levels of aflatoxin B (AFB), ochratoxin A (OTA), zearalenone (ZEN), deoxynivalenol (DON) and fumonisins (FUM) in unprocessed cereals (n = 189) and cereal-based products (n = 61) were determined using validated ELISA methods. All samples originated from either conventional or organic production corresponded to the 2015 harvest in Croatia. Based on the mean mycotoxin concentrations, the risk for the consumer to exceed the tolerable daily intake (TDI) for these toxins by the consumption of both types of cereals and cereal-based products was assessed. Mycotoxin contamination of organic cereals and organic cereal-based products was not significantly different (p > 0.05). Given that the exposure assessment resulted in a small fraction of the TDI (maximum: DON, 12% of TDI), the levels of the investigated mycotoxins in both types of cereals and cereal-based products from the 2015 harvest did not pose a human health hazard.
在本研究中,使用经过验证的酶联免疫吸附测定(ELISA)方法测定了未加工谷物(n = 189)和谷物类产品(n = 61)中黄曲霉毒素B(AFB)、赭曲霉毒素A(OTA)、玉米赤霉烯酮(ZEN)、脱氧雪腐镰刀菌烯醇(DON)和伏马菌素(FUM)的含量。所有样品均来自克罗地亚2015年收获季的传统生产或有机生产。基于霉菌毒素的平均浓度,评估了消费者通过食用这两类谷物和谷物类产品而超过这些毒素每日耐受摄入量(TDI)的风险。有机谷物和有机谷物类产品的霉菌毒素污染没有显著差异(p>0.05)。鉴于暴露评估结果显示TDI的占比很小(最大值:DON,占TDI的12%),2015年收获季的这两类谷物和谷物类产品中所研究霉菌毒素的含量未对人类健康构成危害。
