Reducing the need for animal testing while increasing efficiency in a pesticide regulatory setting: Lessons from the EPA Office of Pesticide Programs' Hazard and Science Policy Council.

As part of EPA's commitment to reducing animal testing, the Office of Pesticide Programs (OPP) created the Hazard and Science Policy Council (HASPOC). This group considers requests for waiving animal study requirements for human health risk assessments and makes recommendations based on a weight-of-the-evidence approach. Since its inception in 2012, the HASPOC has evaluated over one thousand requests to waive animal studies required by default for pesticide evaluation.

The use of developmental neurotoxicity data in pesticide risk assessments.

Following the passage of the Food Quality Protection Act, which mandated an increased focus on evaluating the potential toxicity of pesticides to children, the number of guideline developmental neurotoxicity (DNT) studies (OPPTS 870.6300) submitted to the U.S.

A retrospective analysis of toxicity studies in dogs and impact on the chronic reference dose for conventional pesticide chemicals.

Prior to October 2007, the US Environmental Protection Agency (EPA) required both 13-week and 1-year studies in Beagle dogs be submitted in support of registration for pesticides. Following an extensive retrospective analysis, we (the authors) determined that the 1-year toxicity dog study should be eliminated as a requirement for pesticide registration. The present work presents this retrospective analysis of results from 13-week and 1-year dog studies for 110 conventional pesticide chemicals, representing more than 50 classes of pesticides.
