Good Agricultural Pra​ctices (GAP) & Good Handling Practices (GHP)

GAP & GHP audits are offered by the Oregon Department of Agriculture (ODA) under the USDA Federal-State Audit Program. These voluntary audits are based on the Food and Drug Administration (FDA) Guide to Minimize Microbial Food Safety Hazards for Fresh Fruits and Vegetables. GAP & GHP audits are provided by USDA-trained and licensed ODA auditors in seven districts across the state of Oregon. With GAP & GHP certification, businesses can assure buyers and consumers that they have taken proactive measures to reduce the risk of contamination by adhering to generally recognized industry best practices.
GAP & GHP audit services offered by ODA include:
  • ​USDA GAP & GHP Audit
  • Produce GAPs Harmonized Audit


The USDA GAP&GHP audit is divided into seven sections, each of which covers a specific portion of the supply chain. USDA considers a good agricultural practices (GAP) audit to consist of Part 1 (Farm Review) and Part 2 (Field Harvest & Field Packing Activities). USDA considers a good handling practices (GHP) audit to consist of Part 3 (House Packing Facility) and Part 4 (Storage & Distribution) for pre farm-gate operations, or Part 6 (Wholesale Distribution Center/Terminal Warehouse) for post farm-gate operations. Part 7 (Food Defense Procedures) is an optional scope for those operations which need verification of food defense.

The USDA GAP/GHP audit checklist, application materials, and other resources are provided below.

Produce GAPs Harmonized Audit 

USDA incorporated the United Fresh Produce GAPs Harmonized Food Safety Standard into its GAP & GHP audit program in 2011. There are two standards used for Produce GAPs Harmonized Audits: the "Field Operations and Harvesting Harmonized Food Safety Standard" and the "Post-harvest Operations Harmonized Food Safety Standard." The official versions of these standards are posted on the United Fresh Produce GAPs Harmonizations Initiative website​.

The Produce GAPs Harmonized Audit checklist, application materials, and other resources are provided below.​
