Food Policy Bleg

I'm moderating a panel of food safety policy experts on Thursday, and I'm immersing myself in the topic. Informed readers are hereby solicited to submit areas of concentration so this journalist can pretend like he knows what he is talking about. Is the FDA doing its job? Are new regulations going to force farmer's markets out of business? Have industry self-policing mechanisms failed? How do we approach the complex question of traceability? Etc.
