Abstract

BACKGROUND

This study was carried out to investigate the individual and combined contamination of aflatoxin B (AFB), deoxynivalenol (DON), and zearalenone (ZEN) in feeds in China between 2021 and 2024. A total of 23,003 feed samples, including 17,489 feedstuff samples and 5,514 complete feed samples, were collected from different provinces of China for mycotoxin analysis.

RESULTS

The analyzed mycotoxins displayed considerably high contamination in the feed samples, with the individual contamination of AFB, DON, and ZEN were 20.0%-100%, 33.3%-100%, and 85.0%-100%, respectively. The average concentrations of AFB, DON, and ZEN were 1.2-728.7 μg/kg, 106-8,634.8 μg/kg, and 18.1-3,341.6 μg/kg, respectively. Notably, the rates over China's safety standards for AFB, DON, and ZEN in raw ingredients were 9.7%, 2.7%, and 15.7%, respectively. Meanwhile, 3.5%, 1.1%, and 8.7% of analyzed complete feeds exceeded China's safety standards for AFB, DON, and ZEN, respectively. Moreover, the co-contamination rates of AFB, DON, and ZEN in more than 70% of raw ingredients and 87.5% of complete feed products were 60.0%-100% and 61.5%-100%, respectively.

CONCLUSION

This study reveals that the feeds in China have commonly been contaminated with AFB, DON, and ZEN alone and their combination during the past four years. These findings highlight the significance of monitoring mycotoxin contaminant levels in domestic animal feed and the importance of carrying out feed administration and remediation strategies for mycotoxin control.

摘要

背景

本研究旨在调查2021年至2024年中国饲料中黄曲霉毒素B（AFB）、脱氧雪腐镰刀菌烯醇（DON）和玉米赤霉烯酮（ZEN）的单一及复合污染情况。从中国不同省份收集了总共23,003份饲料样本，包括17,489份饲料原料样本和5,514份全价饲料样本，用于霉菌毒素分析。

结果

所分析的霉菌毒素在饲料样本中显示出相当高的污染水平，AFB、DON和ZEN的单一污染率分别为20.0% - 100%、33.3% - 100%和85.0% - 100%。AFB、DON和ZEN的平均浓度分别为1.2 - 728.7μg/kg、106 - 8,634.8μg/kg和18.1 - 3,341.6μg/kg。值得注意的是，原料中AFB、DON和ZEN超过中国安全标准的比例分别为9.7%、2.7%和15.7%。同时，分析的全价饲料中分别有3.5%、1.1%和8.7%超过了中国AFB、DON和ZEN的安全标准。此外，超过70%的原料和87.5%的全价饲料产品中AFB、DON和ZEN的复合污染率分别为60.0% - 100%和61.5% - 100%。
