---|---|---|---|
A. alliaceusb | A. ochraceus group | Penicillium | |
1997 | 1.85 (0.1) | 0.003 (0.1) | 0 (0.6) |
1998 | — (0.0) | 0 (0.1) | 0 (0.5) |
1999 | 0.81 (0.1) | 0.005 (0.1) | 0 (1.1) |
Ten orchards were sampled each year; a total of 100 figs per orchard were collected in 1997, and 200 per orchard in 1998 and 1999. The limit of detection of ochratoxin A was 1 ng/g. For A. alliaceus and A. ochraceus, all visibly infected figs from each orchard were pooled; for Penicillium, figs from all orchards were pooled for each year.
Some fig samples with A. alliaceus also had colonies of the A. ochraceus group; we counted these mixed samples only as A. alliaceus.
