Research on procuring data for exposure assessment
The risks linked to foods and consumer products are diverse and complex. In order to identify a possible threat to consumers, information is needed about the intake of pathogens and contaminants. The precondition for risk assessment is, therefore, knowledge about the occurrence, spread and intake of harmful pathogens, contaminants, products and their chemical substances. One focus of BfR research is, therefore, the development of methods to collect data within the framework of risk analysis as the basis for exposure assessment.
Standardised, simple screening methods as well as modern statistical methods are needed to collect data and assess exposure. BfR develops these methods further in order to be able to give a realistic assessment of the risks with an acceptable degree of effort.
The research focuses on the development of finely tuned variability-related approaches to exposure assessment. Important data sources are food consumption studies, the levels of agents in foods and consumer products as well as data which provide information on the handling of consumer products in daily life (consumer behaviour). Within this framework BfR is involved, amongst other things, in the User and Scientific Advisory Committee of the National Food Consumption Study II which is co-ordinated by the Federal Research Centre for Nutrition and Food (BFEL). It also co-operates closely with other public agencies and institutions on the national and European levels (European Food Safety Authority (EFSA), Joint Research Centre of the European Commission (JRC), Federal Office of Consumer Protection and Food Safety (BVL), Robert Koch Institute (RKI)).
