Subject: Aldicarb Phone & E-mail Correspondence between EPA & Bayer Crop-Science

From: K. Avivah Jakob, Chemical Review Manager Re-evaluation Managment and Implimentation Branch IV Pestcide Re-evaulation Division (7508P)

Minutes: The Environmental Protection Agency’s (EPA) O ffice of Pesticide Programs (OPP) has recently completed a revised acute probabilistic aggregat e dietary (food and drin king water) exposure and risk assessment for aldicarb. The revised 2010 risk assessment is based on comparative cholinesterase assay (CCA) and new food and resi due data which were recently submitted to the Agency. EPA’s revised dietary e xposure and risk assessment indi cates that aldicarb no longer meets the Agency’s rigorous food safety sta ndards and may pose unacceptable dietary risks, especially to infa nts and young children.

EPA corresponded with the technical registrant of al dicarb, Bayer Crop-Science, via telephone and E-MAIL on the dates provided below. During these correspondences, EPA and the registrant discussed possible opti ons to address the dietary risks of concern identified in the revised 2010 dietary risk assessment. The purpo se of these correspondences was to develop an approach that would full y mitigate all identified dietary risks of concern.
