Center for Produce Safety funds 12 new research projects with $ 3.9 million

The Center for Produce Safety (CPS) funded 12 new research projects, valued at just over $ 3.9 million, to help answer some of the industry’s most pressing food safety questions .

The topics included in the 12 projects are risk assessment and mitigation of Listeria monocytogenes and Salmonella, control of Cyclospora and sanitation of collection bins and collection bags. A full list is provided below, with links to the project summaries. From leafy greens and fruit trees to onions, the research has been endorsed by industry experts on the CPC Technical Committee and is expected to begin in January 2022.

“CPS thanks our campaign contributors and specialty crop block grant programs in California, Florida, Texas and Washington for their commitment to food safety,” said Vic Smith, volunteer board chair of CPS and CEO of producer-shipper JV Smith Companies. .

“CPS succeeds thanks to our unique community: the contributors who fund our work, the researchers who answer our questions, the technical committee which guides them and the board of directors which allows us to stay focused on the mission: to fund science, finding solutions and fueling change.

Joy Waite-Cusic, Ph.D., associate professor, Oregon State University, is leading one of two onion research projects funded by CPS. Waite-Cusic said,

“Dry bulb onions have generally been viewed as a low-risk crop, but the 2020 outbreak has occurred in the United States and, more recently, an outbreak associated with Mexican onions. The US investigation into the outbreak failed to identify the cause of the Salmonella contamination, ”said Waite-Cusic. “Our CPS project is designed to assess how specific industrial practices, including water and clay applications, can contribute to widespread contamination and lead to an epidemic.”

Kansas State University Associate Professor Valentina Trinetta, Ph.D., a first-time CPS-funded scientist, said, “Our research aims to develop scientific recommendations that will help improve cleaning and cleaning practices. sanitation for harvesting operations while managing the sanitation of picking bags and harvesting bins for the tree fruit industry.

All projects will begin in January 2022. Results will be communicated to industry by researchers at the annual CPS Research Symposium and through CPS through other knowledge transfer activities, including the CPS website. the CPC.

The CPS Research Fellowships are made possible by funds provided by the Center for Produce Safety campaign contributors, the California Department of Food and Agriculture’s Specialty Crop Block Grant programs, the Washington State Department of Agriculture, the Florida Department of Agriculture , and Consumer Services and the Texas Department of Agriculture.
