Workshop ‘The Potential for Incorporating Data on Occurrence and Consumer Loyalty into Dietary Exposure Models’

Dublin, Ireland
14/10/2019

Background
Many methods routinely used for the assessment of dietary exposure to chemicals such as food additives, flavours, enzymes and food contact materials assume that all foods in a category where the substance is permitted will contain that chemicals and often at the maximum permitted levels. This distorts the exposure assessment because in reality not all foods in a given category will have any technological need for the chemical and in most cases, other substances are available that can perform the same function. In reality long-term exposure will reflect overall patterns of substance use, unless there is a tendency to strong consumer loyalty.

Objectives
More realistic dietary exposure models would take into account the range of possible concentrations of a chemical in food, the proportion of foods in a given category that contain the substance, and the effect of consumer loyalty on individual consumption behavior.
We aim to draw together experts in dietary exposure modelling, food additive and other food chemicals occurrence data, consumer behavior statistics and data analysis. Together, we will work to review the available information and to consider potential methods for incorporating occurrence frequency data and quantitative information about consumer loyalty into realistic exposure models.

Expected Outcome
A peer-reviewed publication covering the discussions will be produced soon after the workshop.
