The effects of the elimination of fungi and mycotoxins in imported green coffee beans were examined. Each sample was divided into 3 types (22 samples each) ; 1) green coffee beans before handpicking, 2) good beans after handpicking, 3) bad beans after handpicking. All the samples were tested for both fungi and contaminations of ochratoxin-A (OCT-A). OCT-A was detected in 11 out of 22 bad samples (50%, x=6.14 ppb, range 0.08-72.7 ppb), in 7 out of 22 good samples (32%, x=0.49 ppb, range 0.08-7.67 ppb), and in 9 out of 22 samples before handpicking (41%, . x=0.79 ppb, range 0.16-7.20 ppb), respectively. Levels of OCT-A and numbers of fungi in green coffee beans were decreased by the handpicking method.
