The objective of this study was to develop a quantitative Monte Carlo exposure assessment model for
mycotoxins in dairy milk and to assess the potential human exposure levels. Mean concentrations of
mycotoxins in milk were estimated using the simulation model (Aflatoxin M1 = 0.0161 lg/kg, Ochratoxin
A = 0.0002 lg/kg, Deoxynivalenol = 1 lg/kg, Fumonisin B1 = 0.36 lg/kg, Zearalenone = 0.39 lg/kg, T-2 =
0.0722 lg/kg) while the simulated tolerable daily intakes (TDIs) from milk for males and females all fell
below European Union guidelines. Aflatoxin M1 was the toxin of greatest concern as it had potential to
exceed the EU limit of 0.05 lg/kg in milk. The sensitivity analysis identified the concentration of toxins in
maize as the area which needs most attention in relation to crop management and agricultural practice.
The sensitivity analysis assessed also identified the carry over rate as a factor closely related to risk and as
a factor which required further research.
