| Abstract: |
| In order to provide a scientific basis for the prevention of foodborne diseases in Guigang, Guangxi, a total of 625 edible vegetable oil samples were collected from different locations in Guigang from 2018 to 2022, and aflatoxin B1 (AFB1) was detected by post-column derivatization high performance liquid chromatography method in GB 5009.22-2016. The exposure risk of AFB1 was assessed using margin of exposure (MOE) method and population risk of liver cancer method. The results showed that in 625 samples, the detection rate of AFB1 was 96.80%, and the exceeded rate was 20.00%, among which all the packaged samples were qualified, and the exceeded rate of bulk samples was 31.97%. The detection rate of AFB1 in peanut oil was 97.04%, and the exceeded rate was 24.70%, while the other edible vegetable oils were qualified. The exceeded rate of AFB1 in samples collected from oil mills, grocery stores and street stalls was higher. The daily dietary exposure of AFB1 in edible vegetable oil was 5.26 ng/kg, and the incidence risk of liver cancer caused by AFB1 was 0.236 cases/100 000 people per year, of which bulk oil was 0.581 cases/100 000 people per year and peanut oil was 0.416 cases/100 000 people per year. The MOE value of edible vegetable oil was 76, of which bulk oil was 31, packaged samples were 625, peanut oil was 43, and other oils were 930. In conclusion, the risk of AFB1 contamination and exposure of bulk peanut oil in edible vegetable oils in Guigang is high, and there are certain potential risks of food safety. Supervision should be strengthened and corresponding measures should be taken to improve food safety. |
