Dietary Exposure and Risk Assessment of Aflatoxin B1 in Corn-based Foods in China Using Probabilistic Approach

doi:10.7506/spkx1002-6630-201311006

Abstract

Abstract:

Purpose: To assess Chinese residents’ dietary exposure to aflatoxin B1 (AFB1) from corn-based foods and corresponding
health risk. Methods: Dietary intake of aflatoxin B1 from corn-based foods in different population groups was simulated by Monte
Carlo simulation and Bootstrap sampling, and health risk associated with AFB1 intake was evaluated by applying a quantitative
cancer potency formula developed by Joint FAO/WHO Expert Committee on Food Additives. Results: Simulated AFB1 intake
(90% confidence interval) from corn-based foods in different population groups of high corn consumption, 2－6-year-old
children, standard adults, urban standard adults and rural standard adults was 29.98 (19.03－68.59), 10.18 (6.46－23.30),
5.46 (3.47－12.49) ng/(kg•d) and 13.37 (8.49－30.60) ng/(kg•d) at the 99th percentile, respectively; and the evaluated cancer
risk was 0.924 (0.587－2.114), 0.314 (0.199－0.718), 0.168 (0.107－0.385) cancers/(105 persons•a) and 0.412 (0.262－0.943)
cancers/(105 persons•a) . Conclusion: The health risk associated with AFB1 in corn-based foods in China is relatively low.

Key words: aflatoxin B1, nonparametric probabilistic approach, dietary exposure, risk, Monte Carlo simulation
