In November 2009, fifty-three experts from sixteen countries met at BfR to discuss and develop the scientific criteria for regulatory decisions on whether substances should be regarded as having endocrine disrupting properties. Among the issues considered were the importance of extending dosing in toxicity studies to the low dose range, the recognition of critical windows of development, and the need to incorporate further end-points in toxicity testing, such as developmental neurotoxicity and developmental immunotoxicity. In its discussions of the various definitions of negligible exposure (a crucial factor in the decision process), the workshop favoured a more science-based definition over the default value of 0.01 mg/kg food laid down in the European plant protection products regulation (Regulation (EC) No. 1107/2009).
