Survey of aflatoxin M1 in raw milk in the five provinces of China.
Aflatoxin M1 (AFM1) is the only mycotoxin that has a legal limit in milk all over the world. In the present study, 360 raw milk samples were collected from Beijing, Hebei, Shanxi, Shanghai and Guangdong provinces in China in September 2010, and their AFM1 levels were determined by using enzyme-linked immunosorbent assay (ELISA). More than three-fourths (78.1%) of the 360 raw milk samples contained AFM1 at concentrations of 5-123 ng L⁻¹. AFM1 contents in all positive samples were far below the Chinese and US legal limit of 500 ng L⁻¹, but 10% of the raw milk samples exceeded the EU legal limit of 50 ng L⁻¹. Moreover, both incidence and content of AFM1 in milk collected from the southern provinces, including Shanghai and Guangdong, were higher than those collected from the northern provinces, including Beijing, Hebei and Shanxi.
