Abstract
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 mu g/kg), aflatoxin B-1 (6-645 mu g/kg), roquefortine C (1-181 mu g/kg), and deoxynivalenol (27-3842 mu g/kg) were the most prevalent contaminants in maize. For peanut samples, aflatoxin B-1 (6-125 mu g/kg) and ochratoxin A (0.3-12 mu g/kg) were the main contaminants, whereas aflatoxin B-1 (6-194 mu g/kg) and penicillic acid (25-184 mu g/kg) were detected in the cassava products. Exposures calculated through maize intake for fumonisin B-1 and aflatoxin B-1 were several-fold higher (2-5 for fumonisin B-1 and 10(4)-10(5) for aflatoxin B-1) than the health-based guidance values of 2 mu g/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.
