Leafy Greens Research

From the Western Institute for Food Safety and Security

March 23, 2009

The Center for Produce Safety at UC Davis and the California Leafy Greens Research Program awarded grants to seven leading scientists to conduct research that will provide the produce industry with new data to help mitigate the food safety risks associated with leafy greens production.

Funded equally by the two organizations, the awards represent the
Center for Produce Safety's first collaboration under the “Partners in Research” program. Partners' grants are co-developed and co-funded with industry partners to address the research priorities of specific commodities, commodity groups and/or growing regions.
