Within the European project called EXPOCHI (Individual Food Consumption Data and Exposure Assessment
Studies for Children), 14 different European individual food consumption databases of children were used to
conduct harmonised dietary exposure assessments for lead, chromium, selenium and food colours. For this, two
food categorisation systems were developed to classify the food consumption data in such a way that these could
be linked to occurrence data of the considered compounds. One system served for the exposure calculations of
lead, chromium and selenium. The second system was developed for the exposure assessment of food colours.
The food categories defined for the lead, chromium and selenium exposure calculations were used as a basis for
the food colour categorisation, with adaptations to optimise the linkage with the food colour occurrence data.
With this work, an initial impetus was given to make user-friendly food categorisation systems for contaminants
and food colours applicable on a pan-European level. However, a set of difficulties were encountered in creating
a common food categorisation system for 14 individual food consumption databases that differ in the type and
number of foods coded and in level of detail provided about the consumed foods. The work done and the
problems encountered in this project can be of interest for future projects in which food consumption data will be
collected on a pan-European level and used for common exposure assessments.
