Government View on Pesticide Surveillance & Enforcement

A Government Perspective on Pesticide Surveillance and Enforcement in Food and the Environment

This presentation reviews the laboratory perspective on the regulation and surveillance of approximately 270 pesticides and how this testing ties into federal government programs. Resulting methods used by the Ohio Department of Agriculture (ODA) Pesticide Residue laboratory show a lower quantitation limit at or below 10 parts per billion in complex matrices using a QuEChERS extraction paired with GC/MS/MS and LC/MS/MS. This work summarizes data found using these methods and compares goals, analysis requirements, and challenges between the USDA Agriculture Monitoring Service Pesticide Data Program and the U.S. EPA Region 5 with respect to pesticide use. Additionally discussed are strategies and challenges of using multiresidue methods on mass spectrometry platforms from the ODA including:

Workflow strategies

• Matrix interferences and cleanup
• Instrumental and methodological considerations, including compatibility of pesticides in these methods
• Method validation requirements and accreditation criteria

Key Learnings

• The strategies for analyzing broad panels of pesticides with both GC/MS/MS and LC/MS/MS
• The approaches to address matrix interferences and consideration for instruments and methodologies
• Method validation requirements and accreditation criteria from the government perspective
