OBJECTIVE: To assess Shenzhen residents' dietary exposure to aflatoxins from 9 kinds of foods and health risk. METHODS: Dietary intake of aflatoxins from local concentration data and foodstuff consumption data was simulated by Mont Carlo nonparametric probability approach. RESULTS: Aflatoxins( AFT) average intake and high intake were 0. 8533 ng/( kg·BW·d) and 2. 1646 ng/( kg·BW·d), respectively. Aflatoxin B1( AFB1) average level intake and higher level intake were 0. 5113 ng/( kg·BW·d) and1. 3264 ng/( kg·BW·d), respectively. The potential risk for cancer using average data was estimated at 0. 0199 people/( ten thousand people·year), even though this was0. 0517 people/( ten thousand people·year) in higher level. Major exposure contribution to food were corn and products, rice and products, and peanut oil, corn oil. CONCLUSION: The current dietary intake of AFB1 and AFT in Shenzhen has no appreciable effect on health. Government action should be maintained and improved in order to guarantee, aiming at major exposure contribution to food, that special human exposure levels are kept was low as possible.
