Center for Produce Safety funding new research projects
To help answer the fresh produce industry’s most urgent food safety questions, the Center for Produce Safety (CPS) has just funded 14 new research projects, valued at just over $3.9 million.
These 14 new projects are designed to answer industry questions about leafy greens production in controlled (indoor) environments, evaluating and mitigating risk from Listeria monocytogenes and Salmonella, and Cyclospora detection. From avocados to leafy greens to tree fruit, researchers’ proposals were first vetted by industry experts on the CPS Technical Committee and other expert volunteers, to ensure the resulting science will best meet industry needs. A complete list of these projects is below.

“These timely new research projects were made possible by the generosity of industry contributors to CPS’s 2020 Campaign for Research, and grants from state Specialty Crop Block Grant Programs in California, Florida, Texas and Washington, all of whom are committed to enhancing fresh produce food safety,” said Joe Pezzini, chair of CPS’s volunteer Board of Directors and senior director of ag operations for Taylor Farms. “Without their support, CPS couldn’t succeed in our mission to fund science, find solutions and fuel change in produce safety.”
One of the 14 projects has already begun and the other 14 projects will begin in November 2022 and January 2023; all will be completed within 1-2 years. Findings will be reported to the industry by researchers at CPS’s annual Research Symposium, and via CPS through summaries posted to CPS’s website and monthly CPS emails conveying research updates.
