CPS invests $3.3 million in new food safety research

The Center for Produce Safety (CPS) has launched 14 new research projects totaling over $3.3 million, aimed at tackling key food safety issues in the fresh produce industry.

The projects, set to begin in January 2025, address pressing concerns such as flood setback distances, brush sanitation and plant-animal co-existence, with a focus on pathogens like E. coli O157, Salmonella, Cyclospora, and hepatitis A.

These initiatives were selected through CPS’s rigorous annual review process and are spearheaded by researchers across eight U.S. states and Mexico. The research is expected to yield significant insights and improvements across the produce supply chain, enhancing safety and operational practices.

Joe Pezzini, CPS Board Chair and senior director of ag operations at Taylor Farms, highlighted the crucial role of industry contributions and grants from Specialty Crop Block Grant Programs in making these projects possible.

“Their support allows us to fund essential research and drive change in produce safety,” said Pezzini.

Notable projects include Abby Snyder, Ph.D. of Cornell University’s investigation into Salmonella risks in onions and Lee-Ann Jaykus, Ph.D. of North Carolina State University’s development of a hepatitis A virus screening assay. These studies aim to provide actionable data for the industry, helping to mitigate risks and improve safety measures.
