Today EPA released its Revised OP Cumulative Risk Assessment. In December 2001 the Agency issued the "Preliminary OP Cumulative Risk Assessment" which was an inaugural review of the results of a new way of analyzing data regarding potential exposure to pesticides. The focus of the December 2001 assessment was on the methods used to describe the risk. In contrast, today's revised risk assessment describes the potential risks of OPs by presenting a range of estimates that reflect the variability inherent in an assessment of this scope. EPA has evaluated over 1,000 OP pesticide tolerances and virtually all of them are now consistent with the highest levels of safety (please n ote that EPA is still evaluating the tolerances for a few of the OP pesticides). This scientific assessment of OP pesticide food safety contains good news for American consumers. After years of rigorous scientific work, it strongly supports our confidence that the United States has one of the safest food supplies in the world.
