Woodland, CA, October 4, 2022 - 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 provided below, with links to the researchers’ project abstracts.
"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 fourteen projects has already begun and the other thirteen 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 other knowledge transfer activities including summaries posted to CPS's website, and monthly CPS emails conveying research updates.
CPS’s research program is made possible by funds provided by the Center for Produce Safety's Campaign Contributors, the Specialty Crop Block Grant programs in California Department of Food and Agriculture, Washington State Department of Agriculture, Florida Department of Agriculture and Consumer Services, and Texas Department of Agriculture.

"We are very excited about this binational effort to provide food safety management tools for the avocado industry through the Center for Produce Safety award. Our exceptional international research team, based in Texas and Mexico, is grateful to CPS evaluators and stakeholders from both sides of the Southern US border for the interest and support of this much-needed research."

University of Arizona
"Our research and extension team are excited to build upon previous CPS funded work focusing on Quantitative Microbial Risk Assessment and leafy greens. This project will specifically tackle our understanding of variability or “breakthrough” in agricultural water treatment at the farm scale. Ultimately, the outcomes of this project will demonstrate how treatment can be one strategy industry can use to reduce human health risks to consumers."
