On-Farm Readiness Reviews
Produce growers and handlers that have not yet undergone their initial PSR inspections are encouraged to request an On-Farm Readiness Review (OFRR) to aid in their preparation process.
An OFRR is a free, voluntary, customized assessment conducted before an initial regulatory inspection that includes a farm walk-around and one-on-one conversations with CDFA PSP staff to discuss how the PSR applies to your operation in a confidential, educational format.
OFRRs can be requested by emailing producesafety@cdfa.ca.gov. Additional information on OFRRs can be found on our OFRR Blog Post.
CDFA Technical Assistance Program
Produce growers and handlers can receive one-on-one technical assistance at no cost by requesting to be connected to the CDFA Technical Assistance Program (TAP). CDFA TAP is a service that offers educational resources and food safety support for produce operators in California.
CDFA TAP participants will be connected to a Technical Assistance Provider from the University of California Cooperative Extension team who can provide customized support on pre-harvest agricultural water rule compliance and inspection preparation.
Request CDFA TAP support by emailing producesafety@cdfa.ca.gov and learn more at https://www.cdfa.ca.gov/is/technicalassistance/.
What is Pre-Harvest Agricultural Water?
Pre-Harvest Agricultural Water refers to water used during growing activities where water is intended to, or is likely to, contact covered produce or food contact surfaces.
Examples of growing activities can include irrigation, crop sprays, fertigation, cooling, frost protection, dust abatement and any other uses where water directly contacts produce or food contact surfaces.
Covered produce means produce that is subject to the requirements of the Produce Safety Rule including the harvestable or harvested part of the crop.
Background on the Pre-Harvest Agricultural Water Final Rule
On May 6, 2024, FDA published a final rule on pre-harvest agricultural water revising certain requirements in Subpart E of the FSMA Produce Safety Rule (PSR) for covered produce (other than sprouts) for enhanced produce safety. The new rule moves from an emphasis on testing pre-harvest water to performing an agricultural water assessment. It does not change existing agricultural water requirements for sprouts or harvest and post-harvest water uses. The final rule went into effect on July 5, 2024.
