Summary of the qualitative evaluation of the impact of uncertainties on the dietary exposure to T2 and HT2

Sources of uncertainty	Directiona
Extrapolation of occurrence data few Member States to whole Europe	+/−
Large proportion of left‐censored data in the final data set	+/−
Using the substitution method at the lower bound (LB) scenario	−
Using the substitution method at the upper bound (UB) scenario	+
Using imputation method	+/−
Lack of data on modified forms	−
Limited occurrence data from several food groups/limited consumption data for certain population groups	+/−
Very high occurrence data for one product reported by only one data provider	+
Consumption data: different methodologies/representativeness/underreporting/misreporting/no portion size standard	+/−
Reporting of consumption data on raw agricultural commodities derived from consumption of processed foods	+
High variability of feedstuffs used and feeding systems for livestock	+/−

^a+ = uncertainty with potential to cause overestimation of exposure; − = uncertainty with potential to cause underestimation of exposure.
