Saturday, Sept. 22 -- California agriculture, the nation's top specialty-crops producer, is impacted by policy and legal issues that are impeding the production and marketing of these crops. Food safety and legal spin-offs have become particularly urgent on a national level. A symposium, hosted by the UC Davis School of Law and scheduled for 9 a.m. to 5 p.m. in the Mondavi Center's Studio Theatre, will examine the intersection of policy, legal, and agricultural issues as they relate to specialty-crop production and marketing.
