Risk assessment of coumarin using the bench mark dose (BMD) approach: Children in Norway which regularly eat oatmeal porridge with cinnamon may exceed the TDI for coumarin with several folds

► Re-assessment of coumarin toxicity and established a new TDI of 0.07 mg/kg. ► Survey on coumarin concentrations in Norwegian foods and conduction of intake calculations for children and adults. ► Risk assessment of coumarin in the Norwegian population. ► Children eating oatmeal porridge with cinnamon may exceed the TDI with several folds.
