CPHST: The Center for Plant Health Science and Technology Part of US Dept of Agriculture (USDA) Assess risks exotic pests pose to food, fiber & environment Identify pathways used by invasive species Develop, adapt & support technology to detect, identify & mitigate impact of significant exotic pests Optimize existing pest management practices Develop new technologies: exclusion, detection survey & management Support disease management / eradication programs Technical support for treatments & facility certification Training & Education
CPHST Agriculture Quarantine Inspection (AQI) Resources • AQI Treatment Scientists at Otis, Gulfport, Mission, Miami, Ft Collins, and Raleigh Labs • Quality Assurance Unit in Raleigh • Risk Analysis Lab in Raleigh • Rearing facilities at Mission, Otis, Moss Landing, Miami • Collaborations with IAEA, Universities, Industry, ARS, and others
Areas Where QPS MB Reduction May Be Achieved • Target Logs, Tiles, Asparagus, Grapes, Flowers • Substitute Washing and Brushing, Systems Approach, Cold, Heat, or Irradiation • Eliminating Need for Treatment through Risk Assessment • Increasing Accuracy of Gas Readings • Sample Selection for Inspection of Propagative Material • Increasing Detection Efficiency • Better Regulatory Tracking and Tracing

Trace Element and Stable Isotope Analysis to Determine Origin of Fruits and Vegetables Intercepted in the Marketplace – A Pilot Project Purpose and Objectives: • Collaboration between CPHST Gulfport and Carson Watts DHS laboratory, Savannah • Build on existing DHS methods for classifying and discriminating the geographic origin of commodities • Assemble a geo-referenced data library of trace elements for fresh commodities (mango) from multiple countries. • Use the assembled data library to classify unknown origin samples as either domestic or foreign source. • Determine carbon and nitrogen contents and stable carbon, nitrogen and oxygen isotopic compositions of commodities from various countries. • Use stable isotope ratios to discriminate the geographic origin of commodities.
Conclusions • FY10 AQI 15 QPS projects totaling more than $500,000 • Building new AQI research lab in Miami to be completed end of FY11 • FY11 AQI research funding will be down because of decline in AQI user fees collected during recession
