本研究从2013年至2015年的四季中，从中国的南部、北部、东北和西部地区采集了1550份生牛乳样品。样品的黄曲霉毒素M1(AFM1)用高效液相色谱(HPLC)分析。2013年，在366个牛奶样本中，21%检出AFM1，其含量介于0.01至0.24μg/L之间。在11.7%的样本中，AFM1含量达到欧盟法定限值&0.05μg/L。阳性样本均值为0.069±0.052μg/L，中位数为0.056μg/L。2014年，在624份原料牛乳样品中检出AFM1的比例为28.5%，含量范围为0.01~0.25g/L，其中7.7%的样品AFM1含量超过0.05g/L，平均值为0.042±0.039μg/L，中位数为0.028μg/L。2015年，在560份原料牛奶样品中，AFMI值为14.1%，含量范围为0.01~0.144μg/L，其中1.8%的样品AFM1含量高于0.05g/L。平均值为0.026±0.024μg/L，中位数为0.017μg/L。结果表明，样品中AFM1值未超过美国中国和食品法典委员会规定的0.5g/Lμg/L的法定限值。从地理上看，中国南部的原料奶样品中AFM1污染比其他地区的样品更多，2013年、2014年和2015年AFM1含量超过0.05g/μg/L的样品数量较多。在整个研究期间，秋季的AFM1水平高于其他季节。根据我们的调查，近年来中国的AFM1污染得到了很好的控制，但仍有一些样品超过了欧盟的法定限值。应考虑更好地预防和管理饲料和牛奶中的黄曲霉毒素，特别是在中国南部地区和秋季。
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 μg/L. In 11.7% of samples, AFM1 levels were >0.05 μg/L, which is the legal limit in the European Union. The mean and median of positive samples were 0.069 ± 0.052 μg/L and 0.056 μg/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 μg/L. Of these samples, 7.7% had AFM1 levels exceeding 0.05 μg/L, with a mean of 0.042 ± 0.039 μg/L and median of 0.028 μg/L. AFMI was detected in 14.1% of 560 raw cow milk samples in 2015, with levels ranging from 0.01 to 0.144 μg/L. In 1.8% of these samples, AFM1 levels were above 0.05 μg/L, with a mean of 0.026 ± 0.024 μg/L and median of 0.017 μg/L. Our results demonstrate that AFM1 levels of the samples did not exceed the legal limit of 0.5 μg/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 μg/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.
