Daily intake estimates of fumonisins in corn-based food products in the population of Parana, Brazil

► The quantification and validation of fumonisins was performed by HPLC/fluorescence and postcolumn OPA derivatisation. ► We evaluate the presence of fumonisins in Brazilian corn-base food products. ► We realized the assessment of exposure for fumonisins. ► The APDI and MPDI of fumonisins estimated for the Brazilian population were below the PMTDI. ► Results indicate that the need for monitoring these foods to minimise the risk of developing oesophageal cancer.
