中文摘要：霉菌毒素因其后遗效应污染动物源性食品，对人体健康具有潜在的风险。镰刀菌毒素污染成为了棘手的问题，特别是在以显著的温度变化为特征的多雨年份。2015年，本研究从克罗地亚四个地区采集了玉米青贮（n=21）、浓缩奶牛饲料（n=56）及牛奶样品（n=105），调查其中的镰刀菌毒素玉米赤霉烯酮（ZEN）、脱氧雪腐镰刀菌烯醇（DON）及伏马菌素（FUM）。研究发现，若考虑这些真菌毒素的每日容许摄入量(TDIs)，则通常认为人体因消费牛奶而增加的健康风险很低，即便是在天气状况有利于用作奶牛饲料的谷物中镰刀菌毒素产生的季节。而异常情况表示特定的牛奶样品，在其中发现了高浓度的ZEN。
外文摘要：Mycotoxins may contaminate food of animal origin due to the carry-over effect and represent a potential risk to human health. The problem of Fusarium mycotoxin contamination becomes an issue especially during rainy years characterised by substantial temperature changes. The aim of this study was to investigate into the level of Fusarium mycotoxins zearalenone (ZEN), deoxynivalenol (DON) and fumonisins (FUM) in maize silage (n= 21), concentrated dairy cattle feeds (n= 56) and cow milk samples (n= 105), taken during 2015 from households located in four Croatian regions. The presence of mycotoxins was determined using validated ELISA methods. A high level of feedstuffs' contamination was evidenced, especially with ZEN, with values higher than recommended observed in 9.5 % of maize silage samples. Fourteen point three percent (14.3 %) of milk samples were DON positive, with the toxin concentrations ranging from 5.4 to 67.3 mu g/L. ZEN was determined in 94.3 % of milk samples, ranging from 0.3 to 88.6 mu g/L. FUM were not detected in any of the analysed milk samples. Given the tolerable daily intakes (TDIs) defined for these mycotoxins, human health risks arising from the consumption of cow milk can generally be considered low, even in times characterised by weather conditions that facilitate the production of Fusarium mycotoxins in cereals subsequently used as dairy cattle feed. The exception represents particular milk samples in which high ZEN concentrations were found.
