Residue chemistry guidelines are designed to determine what the potential residues in food are and how much may be present as a result of pesticide application, so that a tolerance level may be established. Some requirements are established to assist in the enforcement of tolerances by the USDA, FDA, and the states. I realize I have given you a quick overview of the residue chemistry requirements. There are many documents which are available if you should require more information, such as the Subdivision O Residue Chemistry Guidelines, Standard Evaluation Procedures (which are used by reviewers when evaluating the studies), the Data Reporting Guidelines (which provide guidance on preparing final reports), and the Technical Guidance from Phase III of Reregistration. We have also released various papers on studies when additional guidance is required. Most of these documents are available from NTIS. I hope you will consider this information when auditing residue chemistry studies. As I see the efforts that you, the QA professionals, have made to educate yourselves on residue chemistry studies through programs such as this meeting, I have a little more confidence in answering the question "Do you trust them?" with a "Yes." Thank you.
