中文摘要：本研究旨在弄清巴西康科迪亚-SC地区小农场生产的52个鲜奶中黄曲霉毒素M1的污染情况。结果表明执行良好的获得奶牛饲料的措施很重要，因为黄曲霉毒素M1污染牛奶是在动物消化受污染的饲料或青贮饲料后，黄曲霉毒素B1通过生物转化发生的，对动物本身以及牛奶或奶制品的消费者均构成了风险。
外文摘要：The objective of this work was to determine aflatoxin M-1 in fresh milk from fifty-two small farms in the city of Concordia - SC, Brazil. Samples from the cooling tanks of each property were collected from November 2014 to January 2015. The QuEChERS method was used for the extraction of aflatoxin M-1, and quantification was performed in UHPLC-FL. 40.4% of the analyzed samples (eg, 21 samples) showed contamination levels by aflatoxin M-1 above the maximum limit allowed by the Brazilian regulation, which is 0.5 mu g L-1. These results suggest the importance of implementing Good Practices in obtaining feed for dairy cows, since the contamination of milk by aflatoxin M-1 occurs through the biotransformation of aflatoxin B-1, after the ingestion of feed or silage contaminated by the animals, posing risk to the animals themselves, as well as to consumers of milk and dairy products.
