Although mould-based classification is not a validated method for eliminating aflatoxin contaminated figs, we analysed the
correlation between surface mould concentration and aflatoxin contamination. At the classification step (Fig. 6), 98 figs are classified as Mould-Positive and the remaining 74 figs are classified as
Mould-Negative with 100% classification accuracy.
Fortunately, it is observed that the figs with high mould concentration also have high aflatoxin content, as shown in Fig. 7.
Ninety-one of the 98 figs in the Mould-Positive class have aflatoxin higher than 4 ppb, and 71 of the 74 figs in the Mould-Negative class have aflatoxin lower than 4 ppb. It should be noted that the x-axis in Fig. 7 is the surface mould concentration (CFU cm−2) and the y-axis indicates the square root of the mean aflatoxin level of the corresponding mould concentration.
