Center for Produce Safety funds 14 new research projects

In an effort to help answer the fresh produce industry’s most urgent food safety questions, the Center for Produce Safety (CPS) is funding 14 new research projects, valued at more than $3.9 million.

These 14 new projects are aimed at answering industry questions about leafy greens production in controlled environments, evaluating and mitigating risk from Listeria monocytogenes and Salmonella, and Cyclospora detection.

Researchers’ proposals were vetted by industry experts on the CPS Technical Committee and other expert volunteers.

One of the fourteen projects has already begun and the other thirteen projects will begin in Nov. 2022 and January 2023. All will plan on being completed within one to two 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.
