Abstract: [Objective] To understand the contamination level of Aflatoxin M1（AFM1）in dairy products.[Method] The content of AFM1 in 2 099 dairy products in Yinchuan City was determined by colloidal gold immunochromatography rapid detection method and high performance liquid chromatography,and the exposure risks of different populations were evaluated. [Result] The positive detection rate of AFM1 was 9.58%,and the contamination level of milk-containing beverages was the highest. Special attention should be paid to the risk of children aged 2 to 6. [Conclusion] AFM1 was detected in all 10 kinds of dairy products sold in Yinchuan,but the contamination level was within a controllable range. Given that the risk of liver cancer caused by AFM1 among children who consume milk-containing beverages is relatively high,a systematic monitoring mechanism needs to be established and long-term dynamic supervision implemented.

Key words: dairy product, AFM1, milk-containing beverage, risk of liver cancer
