感染玉米黑粉菌（黑粉病）的玉米会产生瘿，在某些文化中被视为美味佳肴。在 4 年期间，黑黑穗病穗的无症状籽粒中的黄曲霉毒素水平平均比从无黑穗病对照穗收获的籽粒高 45 倍，比黑穗病虫瘿中收获的籽粒高 99 倍。在所有年份中，黑穗病瘿中的黄曲霉毒素水平均低于无黑穗病对照玉米粒中的黄曲霉毒素水平。从黑黑穗病穗收获的无症状籽粒中伏马菌素水平比来自无黑穗病对照穗的籽粒高 5.2 倍，比黑穗病虫瘿中高 4.0 倍。黑穗病虫瘿中的伏马菌素水平与无黑穗病对照玉米粒中的伏马菌素水平没有显着差异。这些。研究表明，虽然玉米黑粉病相对不含所研究的霉菌毒素，但这些玉米穗的无症状玉米粒所含的霉菌毒素含量远高于通常认为可供人类直接食用的安全水平。
Corn infected with Ustilago maydis (common smut) produces galls that are valued as a delicacy in some cultures. During a 4-year period, aflatoxin levels in asymptomatic kernels of smutted ears were, on average, 45-fold higher than in kernels harvested from smut-free control ears and 99-fold higher than in smut galls. Aflatoxin levels in smut galls were lower than in kernels of smut-free control corn in all years combined. Fumonisin levels in asymptomatic kernels harvested from smutted ears were 5.2-fold higher than in kernels from smut-free control ears and 4.0-fold higher than in smut galls. Fumonisin levels in smut galls were not significantly different than in kernels of smut-free control corn. These. studies indicate that, although corn smut was relatively free of the mycotoxins studied, the asymptomatic kernels of those ears contained mycotoxins at levels much higher than usually considered safe for direct human consumption.
