The objective of this study was to investigate the individual and combined contamination of aflatoxin B₁ (AFB₁), zearalenone (ZEN) and deoxynivalenol (DON) in feedstuffs from different Provinces of China between 2016 and 2017. A total of 1569 samples, including 742 feed ingredients and 827 complete pig feed samples, were collected from various regions of China for mycotoxins analysis. The results showed that individual occurrence rates of AFB₁, ZEN, and DON were more than 83.3%, 88%, and 74.5%, respectively, in all the tested samples. DON was the most prevalent contaminant, followed by ZEN and AFB₁, with the average concentrations ranging from 450.0-4381.5 μg/kg, 2.3-729.2 μg/kg, and 1.3-10.0 μg/kg, respectively. Notable, 38.2%, 10.8%, and 0.6% of complete pig feeds were contaminated with DON, ZEN, and AFB₁ over China's regulatory limits, respectively. Moreover, over 75.0% analyzed samples were co-contaminated with two or three mycotoxins. In conclusion, the current study revealed that the feedstuffs in China were severely contaminated with DON, followed by ZEN and AFB₁ during the past two years. These findings highlight the importance of monitoring mycotoxins in livestock feed and implementing feed management and bioremediation strategies to reduce mycotoxin exposure.
本研究旨在调查 2016 年至 2017 年期间中国不同省份饲料中黄曲霉毒素 B₁（AFB₁）、玉米赤霉烯酮（ZEN）和脱氧雪腐镰刀菌烯醇（DON）的单独和联合污染情况。共采集了 1569 个样本，包括 742 种饲料原料和 827 种全价猪饲料，来自中国各地进行霉菌毒素分析。结果表明，在所有检测样品中，AFB₁、ZEN 和 DON 的个体发生率均超过 83.3%、88%和 74.5%。DON 是最常见的污染物，其次是 ZEN 和 AFB₁，其平均浓度范围分别为 450.0-4381.5μg/kg、2.3-729.2μg/kg 和 1.3-10.0μg/kg。值得注意的是，38.2%、10.8%和 0.6%的全价猪饲料中 DON、ZEN 和 AFB₁的含量超过了中国的限量标准。此外，超过 75.0%的分析样品同时受到两种或三种霉菌毒素的污染。综上所述，本研究表明，在过去两年中，中国的饲料中 DON 污染最为严重，其次是 ZEN 和 AFB₁。这些发现强调了监测牲畜饲料中霉菌毒素以及实施饲料管理和生物修复策略以减少霉菌毒素暴露的重要性。
