Concentration distribution of AFs.

Distribution of AF level (μg/kg) no.
Samples	No. of positive/total samples	Positive(%)	<1	1 to 10	>10 to 20	>20	Mean ± SD (μg/kg)	Range (μg/kg)
Turmeric	0/20	0	0 (0%)	14 (70%)	0 (0%)	0 (0%)	2.84 ± 1.08	1–5.3
Red pepper	16/20	80	0 (0%)	4 (20%)	8 (40%)	8 (40%)	28.21 ± 20.8	3.29–77.3
Black pepper	0/20	0	0 (0%)	4 (20%)	0 (0%)	0 (0%)	1.53 ± 0.62	1.17–2.47
Cinnamon	0/20	0	0 (0%)	2 (10%)	0 (0%)	0 (0%)	2.04 ± 0.04	2.01–2.07

Note: samples are considered to be positive at AF concentrations exceeding 10 μg/kg ().
