Mycotoxins level in highly contaminated flour samples (n = 97).
| Mycotoxin | Threshold (ng/g) | No. of samples | Levels of mycotoxin (ng/g) |
||
|---|---|---|---|---|---|
| Average | median | Ranges | |||
| Aflatoxin | below KEBS (<10)a | 15 | 5.7 | 5.8 | 1.3–9.7 |
| above KEBS (>10) | 82 | 130 | 66 | 10.2–1290 | |
| Fumonisin | below KEBS (<1000) | 40 | 254 | 153 | 0–936 |
| above KEBS (>1000) | 57 | 3580 | 2940 | 1030–11600 | |

As per method section 2.1, these 97 samples were selected out of a pool of 885 samples based on an AF measurement >10 ng/g by the field team in Kenya that collected the samples. Some of these samples tested AF < 10 ng/g (but with detectable aflatoxin) upon receipt at Illinois, which is not unreasonable given the known skewness of aflatoxin contamination.
