中文摘要：黄曲霉毒素B1（AFB1）是一种真菌代谢物，国际癌症研究机构将其归入1类高致癌化合物。肝脏将源于污染饲料的AFB1生物转化生成黄曲霉毒素M1，很容易扩散到动物奶中。因此，为人类，特别是婴儿和成人提供健康的牛奶就势必要监测奶牛饲料中的黄曲霉毒素B1的水平。本研究从2014年10月到2015年9月，监测了包括商业上可用的动物饲料、新鲜饲料和剩余面包饲料三种不同类型的奶牛饲料中AFB1的水平。结果表明剩余面包样品和商品饲料中含有高浓度的AFB1，因此，应采取严格措施，防止奶牛饲料污染并同时防止黄曲霉毒素污染牛奶。
外文摘要：Afatoxin B1 (AFB1) is a fungal metabolite and highly carcinogenic compound of category 1 according to the International Agency for Research on Cancer. In the liver AFB1 from contaminated feed is bioconverted into afatoxin M1 and can be easily diffused to the animal milk. Provision of healthy milk for humans, particularly infants and adults, therefore, entails monitoring of AFB1 level in the feed for dairy animals. In the present study, AFB1 level was monitored in three different types of animal feed comprising commercially available animal feed, fresh fodder and leftover bread fed to dairy animals between October 2014 and September 2015. AFB1 was found in all collected feed samples at the amounts: 30.5%, 2.8% and 88.9% in commercial feed, fresh fodder and leftover bread samples, respectively. All these levels were over the EU permissible limits (5 μg · kg⁻¹). Mean maximum levels of AFB1 were observed in all samples collected in the winter season, whereas the mean minimum levels - in the summer months. The results of the present study indicated that the leftover bread samples and commercial feed contain high levels of AFB1, and so strict measures should be adopted to prevent dairy animal feed and at the same time the animal milk from afatoxin contamination.
