Fig. 4.

Season-wise mycotoxin contamination levels among samples with detectable levels of AFB1, FB1, and DON. Seasons: PrW = pre-winter, W = winter, PoW = post-winter, PrS = pre-summer, S = summer, PoS = post-summer. Data are plotted on log₁₀ scales, with axis values representing actual (non-transformed) toxin concentrations. (A) AFB1 levels (μg/kg) in stored samples of groundnut, maize, pearl millet, and rice, (B) FB1 levels (μg/g) in stored samples of maize and pearl millet, (C) DON levels (μg/kg) in stored wheat samples. Red shaded regions correspond to levels above regulated legal maxima of 15 μg/kg, 2 μg/g, and 1 μg/g for AFB1, FB1, and DON, respectively.
