A step-wise risk assessment, using previously
accrued survey data, was used to estimate the risk of
acquiring cryptosporidiosis or giardiosis by consumption
of mung bean sprouts in Norway. The model is
simple and highlights the assumptions necessary, due
to data gaps, in making these estimates. As further
data become available the model can be expanded andrefined to include these, and to provide more accurate
and realistic estimates. Finally, although there is
uncertainty, the estimates of risk are non-trivial and
as such would warrant some degree of attention by
public health authorities to better understand the
potential for risk from this source and subsequently
refine the analysis in order to better manage the risk
