中文摘要：本研究收集了2013-2015年间我国南方、北方、东北和西部地区四季共1550份鲜奶样品并用高效液相色谱法（HPLC）分析样品中的黄曲霉毒素B1（AFM1）。结果表明，近几年我国的AFM1污染得到了良好的控制；然而，一些样品仍然超过了欧盟（EU）限量。尤其需要考虑如何更好地预防和管理我国南方以及夏天的饲料和牛奶中的黄曲霉毒素。
外文摘要：In the present study, a total of 1550 raw cow milk samples were collected from Southern, Northern, Northeast, and Western regions of China during the four seasons from 2013 to 2015. Samples were analyzed for aflatoxin M1 (AFM1) using high performance liquid chromatography (HPLC). In 2013, AFM1 was detected in 21% of 366 raw cow milk samples with levels ranging between 0.01 and 0.24 mu g/L. In 11.7% of samples, AFM1 levels were >0.05 mu g/L, which is the legal limit in the European Union. The mean and median of positive samples were 0.069 +/- 0.052 mu g/L and 0.056 mu g/L, respectively. In 2014, AFM1 was detected in 28.5% of 624 raw cow milk samples, with levels ranging from 0.01 to 0.25 mu g/L. Of these samples, 7.7% had AFM1 levels exceeding 0.05 mu g/L, with a mean of 0.042 +/- 0.039 mu g/L and median of 0.028 mu g/L. AFMI was detected in 14.1% of 560 raw cow milk samples in 2015, with levels ranging from 0.01 to 0.144 mu g/L. In 1.8% of these samples, AFM1 levels were above 0.05 mu g/L, with a mean of 0.026 +/- 0.024 mu g/L and median of 0.017 mu g/L. Our results demonstrate that AFM1 levels of the samples did not exceed the legal limit of 0.5 mu g/L in China, the United States, and Codex Alimentarius Commission. Geographically, AFM1 contamination was more predominant in raw cow milk samples from Southern China than in those from other regions, with a higher number of samples containing AFM1 levels above 0.05 mu g/L in 2013, 2014, and 2015. AFM1 levels were higher in autumn than in the other seasons during the entire study period. According to our survey, AFM1 contamination has been well-controlled in China during recent years; however, some samples still exceeded the European Union (EU) legal limit. Better prevention and management of aflatoxins in both feed and milk should be considered especially in Southern regions of China and in autumn.
