• Limited survey for aflatoxin contamination of polished rice imported into Japan

抄録

Analysis of aflatoxins (AF) B₁, B₂, G₁ and G₂ in imported polished rice samples from Thailand, Pakistan and Bangladesh was performed by direct competitive ELISA (direct cELISA) and immunoaffinity column with high performance liquid chromatography (IAC-HPLC) methods using monoclonal antibody. Direct cELISA method with the detection limit of 2.8 μg/kg for AFB₁ gave negative results in all of 20 samples analyzed. On the other hand, using IAC-HPLC with the detection limit of 0.1 μg/kg for each toxin, AFB₁ was detected in five out of 20 (25 %) imported polished rice samples; in three Thailand and two Pakistan samples, with the concentrations ranging 0.1 - 0.3 μg/kg. In addition, AFB₂ (0.1 μg/kg) was detected in one of the Pakistan rice sample contaminated with AFB₁ (0.3 μg/kg). Even though the level of AF contamination in imported rice samples found to be well below the Japanese limit (10 μg/kg), AF contamination in rice as a staple food of Asian is an important issue for evaluation of human exposure due to the frequency of intake.
