BfR calculator for estimating consumer exposure to biocide residues in food

This calculator has been developed by the German Federal Institute for Risk Assessment (BfR) (1) to support competent authorities and industry when performing dietary risk assessment for biocidal products. It presents a tool to facilitate the estimation of dietary risk from consumer exposure to biocidal active substances used in domestic households as described in the Guidance on Estimating Dietary Risk from Transfer of Biocidal Active Substances into Foods - Non-professional Uses (Guidance Non-professional Uses) (2). It applies assumptions and default values as given in the guidance document.

The exposure models presented in this calculator are not a comprehensive collection of scenarios. During evaluation it must be ensured that the chosen scenario is applicable to the intended use to be evaluated. Adjustment of existing scenarios or development of new scenarios will be required on a case-by-case basis. The list of scenarios in this calculator may be extended as more active substances and their uses in biocidal products are evaluated.

The "Examples" spreadsheet contains calculations for various scenarios to illustrate the use of this calculator. Results for the examples given in the Guidance Non-professional Uses may slightly deviate from results produced by this calculator due to rounding differences.
