Abstract

Two hundred and fourteen unprocessed corn samples (1997-98 harvest), collected at wholesale markets in different regions in Brazil, were surveyed for the occurrence of mycotoxins. The samples were analysed for aflatoxins B1, B2, G1, G2, zearalenone and fumonisin B1 using in-house validated methods. The occurrence of aflatoxin B1, zearalenone and fumonisin B1 was found in 38.3, 30.4 and 99.1% of the samples, respectively. Aflatoxin B1, zearalenone and fumonisin B1 contamination levels varied from 0.2 to 129, 36.8 to 719, and 200 to 6100 microg/kg, respectively. The co-occurrence of the two carcinogenic mycotoxins aflatoxin B1 and fumonisin B1 was observed in 100% of the aflatoxin-contaminated samples (82 samples). Co-occurrences of aflatoxin B1: zearalenone: fumonisin B1 and aflatoxin B1: aflatoxin B2: fumonisin B1 were found in 18 and 43 samples, respectively.

摘要

对在巴西不同地区批发市场采集的214份未加工玉米样品（1997 - 1998年收获季）进行了霉菌毒素检测。采用内部验证方法对样品中的黄曲霉毒素B1、B2、G1、G2、玉米赤霉烯酮和伏马毒素B1进行分析。结果发现，黄曲霉毒素B1、玉米赤霉烯酮和伏马毒素B1的检出率分别为38.3%、30.4%和99.1%。黄曲霉毒素B1、玉米赤霉烯酮和伏马毒素B1的污染水平分别在0.2至129微克/千克、36.8至719微克/千克和200至6100微克/千克之间。在所有受黄曲霉毒素污染的样品（82份）中均观察到两种致癌霉菌毒素黄曲霉毒素B1和伏马毒素B1同时存在。分别在18份和43份样品中发现了黄曲霉毒素B1:玉米赤霉烯酮:伏马毒素B1和黄曲霉毒素B1:黄曲霉毒素B2:伏马毒素B1同时存在的情况。
