本研究的目的是调查2016年至2017年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）的单独和组合污染情况。从中国不同地区收集了1569份样品，包括742份饲料原料和827份全价猪饲料样品，进行霉菌毒素分析。结果显示，所有检测样本中AFB1、ZEN、DON的个体出现率分别大于83.3%、88%、74.5%。 DON 是最常见的污染物，其次是 ZEN 和 AFB1，平均浓度范围分别为 450.0–4381.5 μg/kg、2.3–729.2 μg/kg 和 1.3–10.0 μg/kg。值得注意的是，38.2%、10.8% 和 0.6% 的猪全价饲料中 DON、ZEN 和 AFB1 的污染分别超出了中国的监管限值。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。总之，目前的研究表明，过去两年中国饲料中DON污染严重，其次是ZEN和AFB1。这些发现强调了监测牲畜饲料中的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。
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.
