Mycotoxins in uncooked and plate-ready household food from rural northern Nigeria

Abstract In order to understand the changes in toxic metabolite profiles in uncooked and cooked foods, samples of flour/grain ( n  = 40) and their corresponding plate-ready food ( n  = 39) were collected from 40 households in two states of northern Nigeria. The food samples were analyzed for multiple fungal metabolites by LC-MS/MS and daily intakes of mycotoxins in the diets were estimated and compared to established margin of exposure (MOE) and tolerable daily intake (TDI) values. Both food groups contained 65 fungal and plant metabolites, inclusive of 23 mycotoxins. The mean concentrations of aflatoxin B 1 , beauvericin, fumonisin B 1 (FB 1 ), FB 2 , FB 3 , hydrolysed FB 1 , moniliformin and nivalenol were significantly ( p
