Evaluation of conventional and organic italian foodstuffs for deoxynivalenol and fumonisins B(1) and B(2).
Two lots of human foodstuffs from conventional and organic brand foods were purchased from supermarkets and analyzed for three Fusarium toxins, deoxynivalenol, by GC-ECD, and fumonisins B(1) and B(2) (FB(1)-FB(2)), by LC-MS. The occurrence of deoxynivalenol contamination was higher than 80% in both organic and conventional foods; fumonisin B(1) was found in 20% of organic foods and in 31% of conventional ones and fumonisin B(2) in more than the 32% of the food samples from both the agricultural practices. The highest median concentration of deoxynivalenol occurred in conventional rice-based foodstuffs (207 microg/kg): that of fumonisin B(1) in conventional maize-based foods (345 microg/kg) and that of fumonisin B(2) in organic wheat-based foods (210 microg/kg).
