2020年1—12月,博瑞科技检测中心共采集黑龙江、辽宁、内蒙古、北京、天津、河北、山东、山西、陕西、甘肃、宁夏等地区的玉米青贮样本1 184 份,旨在了解2020年国内玉米青贮霉菌毒素污染情况。采用酶联免疫吸附法测定样品中黄曲霉毒素B1、玉米赤霉烯酮、呕吐毒素三大霉菌毒素含量,分析总体污染情况以及不同月份、不同采集区域的污染情况。结果表明：2020年在检测的1 184 份玉米青贮样品中,玉米赤霉烯酮和呕吐毒素污染最为严重,超标率分别为4.36%,6.67%;不同月份的霉菌毒素平均值未出现明显的规律;同一牧场不同月份黄曲霉毒素B1和呕吐毒素差异较大,尤其是呕吐毒素,最高月份和最低月份相差2 649.56 μg/kg。
To study the mycotoxins content in Corn silage in 2020,Borui Technology Testing Center collected 1,184 corn silage samples from Heilongjiang,Liaoning, Inner Mongolia,Beijing,Tianjin,Hebei,Shandong,Shanxi,Shaanxi, Gansu,Ningxia.From January to December,Three kinds of mycotoxins (Aflatoxins B1,Zearalenone,Vomitoxin) contents in corn silage were determined using enzyme linked immunosorbent assay (ELISA).To study the overall pollution and the pollution in different collection areas and different months.The results showed that among the 1,184 corn silage samples,the contamination of zearalenone and Vomitoxin were the most serious with the exceeding rate of 4.36% and 6.67% respectively.The average value of mycotoxins in different months did not show obvious regularity. Aflatoxin B1 and Vomitoxin in different months of the same pasture are different,especially vomiting toxin.The difference between the highest month and the lowest month is 2,649.56 μg/kg.
