Abstract

Mycotoxins are products of moulds that frequently contaminate maize. In this study the presence of mycotoxins fumonisin B1 (FB1), fumonisin B2 (FB2), zearalenone (ZEA) and ochratoxin A (OTA) was determined in 49 maize grain samples collected in autumn 2002. The most frequent finding was that of FB1(100%), followed by ZEA (84%) and OTA (39%), while FB2 was found only in three samples. The co-occurrence of two and three mycotoxins was found in 55 and 37% of samples, respectively. The concentrations (mean +/- SD) of FB1, ZEA and OTA in positive samples were 459.8 +/- 310.7, 3.84 +/- 6.68 and 1.47 +/- 0.38 microg kg(-1), respectively, and the concentrations of FB2 in three positive samples were 68.4, 109.2 and 3084.0 microg kg(-1). Although such low concentrations of mycotoxins are not a significant source of exposure in countries with a European diet, a few samples with extreme values indicate that thorough control is needed.

摘要

霉菌毒素是霉菌的产物，常污染玉米。本研究测定了2002年秋季采集的49份玉米籽粒样品中伏马毒素B1（FB1）、伏马毒素B2（FB2）、玉米赤霉烯酮（ZEA）和赭曲霉毒素A（OTA）的存在情况。最常见的是FB1（100%），其次是ZEA（84%）和OTA（39%），而FB2仅在3个样品中被发现。分别在55%和37%的样品中发现了两种和三种霉菌毒素同时存在的情况。阳性样品中FB1、ZEA和OTA的浓度（平均值±标准差）分别为459.8±310.7、3.84±6.68和1.47±0.38微克/千克，三个阳性样品中FB2的浓度分别为68.4、109.2和3084.0微克/千克。尽管在欧洲饮食的国家中，如此低浓度的霉菌毒素并非重要的暴露源，但少数含有极值的样品表明仍需进行全面控制。
