Abstract (English):: Objective To evaluate the dietary risk of aflatoxin B1 (AFB1) in food oil from a city's residents using exposure limit method and mathematical model method, and give some advice. Methods Edible vegetable oil in the field of production and circulation in Guangdong province was extracted by stratified random method. The AFB1 content was analyzed by enzyme-linked immunosorbent assay (ELISA) and high performance liquid chromatography (HPLC). Based on the dietary consumption of residents in this city, the exposure level of AFB1 in edible oil was calculated, and the dietary risk was assessed by margin of exposure (MOE) method and mathematical model method. Results A total of 341 edible vegetable oils were collected, and the detection rate of AFB1 was 66.0%. The detection rate and content of peanut oil were higher than other varieties (P<0.05). The detection rate and content of bulk samples were significantly higher than that of packaged samples (P<0.05). The content of AFB1 in supermarkets and catering units was lower than that in other places (P<0.05). There was no statistically significant difference in sample detection rate and content in different regions (P>0.05). The city’s residents’ AFB1 exposure level was 3.12 ng/kg bw/d, and the MOE value was 80. The contribution to the incidence of liver cancer was 0.1248/100000. Conclusions The city's residents have a lower contribution to the dietary exposure of AFB1 and the incidence of liver cancer, but it should still cause adequate and sustained public health concerns. In particular, priority should be given to risk management measures for bulk peanut oil, and supervision should be strengthened, and healthy dietary habits of the population should be well guided.
