A total of 420 samples were collected from agrarian households. Whereas 51% (215/420) of the samples were contaminated with one or more toxins; the contamination rates for maize; peanut; and cassava products were 74; 62; and; 24%; respectively. The fumonisins (20-5412 μg/kg); aflatoxin B1 (6-645 μg/kg); roquefortine C (1-181 μg/kg); and deoxynivalenol (27-3842 μg/kg) were the most prevalent contaminants in maize. For peanut samples; aflatoxin B1 (6-125 μg/kg) and ochratoxin A (0.3-12 μg/kg) were the main contaminants; whereas aflatoxin B1 (6-194 μg/kg) and penicillic acid (25-184 μg/kg) were detected in the cassava products. Exposures calculated through maize intake for fumonisin B1 and aflatoxin B1 were several-fold higher (2-5 for fumonisin B 1 and 104-105 for aflatoxin B1) than the health-based guidance values of 2 μg/kg bw/day and 0.15 ng/kg bw/day; respectively. The study design constitutes a good model that can be implemented in other sub-Saharan African countries. © 2014 American Chemical Society;
