Dietary Exposure to Aflatoxins in Some Randomly Selected Foods and Cancer Risk Estimations of Cereals Consumed on a Ghanaian Market

Table 1

HPLC-FLD parameters for validating repeatability, precision, recovery, limit of detection (LOD), and limit of quantification (LOQ) for aflatoxins detection.

Aflatoxin	Limits	Amount (μg/kg)	Repeatability (standard deviation)	Intermediate precision (reproducibility) (%)	Recovery percent (recovery of measurement procedure) (%)	Linearity of regression curve
Limits			<15%	<20	80–120
AFB1	LOD	0.20	5.5%	13.2	107	0.99
	LOQ	0.60
AFB2	LOD	0.17	6.7%	13.4	87.2	0.99
	LOQ	0.51
AFG1	LOD	0.26	7.4%	13.7	113.4	0.99
	LOQ	0.78
AFG2	LOD	0.36	12.1%	12.2	112.8	0.98
	LOQ	1.08

LOD-Limit of detection: LOD for all aflatoxins should be less than 1 μg/kg. LOQ-Limit of quantification: LOQ for all aflatoxins should be less than 3 μg/kg.
