Abstract

A survey for aflatoxin B1 (AFB1) was conducted on 88 food-grade rice samples randomly collected during July and August 2002 in Seoul, Korea. The presence of AFB1 was determined by enzyme-linked immunosorbent assay, and the positive samples from enzyme-linked immunosorbent assay were confirmed using high-performance liquid chromatography. Besides this, from the surveying data from the literature published since 1997, the intake of AFB1 from food in Korea was calculated and compared with the provisional maximum tolerable daily intakes. Naturally occurring AFB1 was found in 5/88 (6%) samples of rice with an average of 4.8 ng g-1. A calculated probable daily intake of AFB1 for Koreans fell into the range 1.19-5.79 ng kg-1 bw day-1, hence exceeding the estimated provisional maximum tolerable daily intakes. In conclusion, the exposure of Koreans to AFB1 could bring about health concerns. This is the first report discovering that rice is the mqjor contributor to the dietary intake of AFB1 in Korea.
