Pre-harvest Testing Comment Period Web Discussion

On June 15, 2022, the submission period associated with revisions on Pre-harvest Product Testing in the LGMA-approved guidelines officially closed. This web discussion offers an opportunity to publicly present and discuss all proposed changes and comments received during the comment period.

Meet the Speaker

To facilitate broad industry engagement and transparency, WG, in partnership with the Arizona and California LGMAs, manages a systematic amendment process based on calendar set by the Oversight Committee. The food safety guidelines adopted by the LGMAs impact the way leafy greens are farmed in California and Arizona and therefore must be based on credible science balanced with practical field implementation.

Proposed changes must meet LGMA criteria to be considered. Proposals should be:

  1. Comprehensive
  2. Accompanied by a statement on how proposed changes will enhance food safety
  3. Include a clear and straightforward scientific basis or rationale, including citations of relevant research if available.

WG invites all stakeholders interested in enhancing the safety of leafy greens to engage in this process.

wgscience@wga.com or visit LeafyGreenGuidance.com.

Content Overview:

This presentation will focus on the following

• Overview of value and limitations of product testing
• Introduction to Appendix C
• Common questions regarding Appendix C

This presentation will not focus on the science behind pre-harvest product testing.

WG will be hosting a webinar on the current science surrounding this new guidance in mid-September.
Stay tuned!
