Since the inception of the California and Arizona Leafy Greens Marketing Agreements (LGMAs), Western Growers (WG) has been at the forefront of revising the written “Commodity Specific Food Safety Guidelines for the Production and Harvest of Lettuce and Leafy Greens” for the industry in both states. These guidelines are known as the LGMA-approved guidelines.

On May 31, 2022, the comment period associated with revisions on Pre-harvest Product Testing in the LGMA-approved guidelines officially closes. Western Growers will host a web discussion to publicly present and discuss all proposed changes and comments received during the comment period. An email with additional webinar details and registration information will be sent out shortly.  

Stakeholders interested in submitting proposed revisions through this process can submit comments until May 31, 2022 at

Proposed changes must be submitted online and meet LGMA criteria to be considered. Proposals should be 1) comprehensive, 2) accompanied by a statement on how proposed changes will enhance food safety, and 3) include a clear and straightforward scientific basis or rationale, including citations of relevant research if available.
