WHAT WE KNOW, DONT KNOW, AND NEED TO KNOW ABOUT PESTICIDE-RESIDUES IN FOOD

Factors contributing to growing public concern about pesticide residues are assessed, with special focus on the need for more accurate and credible exposure assessments. Current knowledge about residues is examined, and found incomplete. The critical need for a resolution of uncertainty over the risk standard governing the setting of "safe" tolerances is highlighted, along with a number of technical issues and assumptions in the risk assessment process. Criteria for the targeting of residue monitoring activities are suggested as one viable option to more effectively protect the public's health.
