OPPTS 860 Residue Chemistry Test Guidelines

CMA), and the USDA are excellent sources of information relative to current regulatory activities which will impact both production agriculture and the setting of tolerances to ensure food safety. The purpose of this article is to summarize the key impacts of the 1996 OPPTS 860 Residue Chemistry Test Guideline series as they impact research associated with field production of RAC samples to be used in establishing safe tolerance limits for pesticides used in commercial agricultural production. 

Supplementary Guidance on Use of OPPTS Residue Chemistry Test Guideline 860.1500 (residue zone maps - Canadian extension) 4/8/98] and efforts are under way to extend the map into Mexico. The EPA cropping regions in which to locate field residue trials in a study are listed in Table 5. Other important items discussed in OPPTS 860.1500 include ... 

Both the Study Director and a QA agent should be present at the first application. SOPs must be followed, documentation must be correct and complete, equipment must be calibrated and its maintenance records must be documented, safety procedures must be in place, and the fine points of application methodology should be discussed with the applicator. Guidelines for applications can be found in Residue Chemistry Test Guidelines , Office of Prevention, Protection and Toxic Substances (OPPTS) 860.1500.
