Key Findings -People in Nigeria are at risk of exposure to mycotoxins(aflatoxins and fumonisins) which both have potentialrisk to human and animal health -We find evidence that many maize products (51.7% ofour samples) had total aflatoxin levels above theregulatory limits in Nigeria while 12.93% of the samplescontained total fumonisin levels higher than the UnitedStates regulatory limit -Aflatoxin and fumonisin contamination in maizeproducts extend beyond production to storage and finalfood products -Adequately addressing the mycotoxin challenge requiresconsideration of the entire maize value chain
