• Federal Food Drug & Cosmetic Act (FD&C Act)
• Food from GE crops must meet the same legal requirements as other foods:
FD&C Act: Legal provisions for all food
General Safety
Food must be safe. Applies to endogenous substances
(post-market authority)
Additives
“Food additives” require premarket review and
approval
Labeling
Labeling must be truthful and not misleading

• Addressed new plant varieties– Including recombinant DNA (rDNA) technology
• Identified potential safety considerations
• Identified applicable legal requirements and concluded that the existing legal framework is sufficient to ensure safety
• Proposed considerations for ensuring safety and compliance before marketing

Evaluating new substances for safety
• What is it?– Prior knowledge– What happens after consumption? (ADME)– What do we know about potential toxicity?
• How much is safe to consume?– Are feeding studies needed?– NOAEL (no-observed-adverse-effect-level)
• How will this use of the substance change exposure levels?– Calculating exposure
• Are expected exposure levels safe?– Margin of exposure– Safety standard: “Reasonable certainty of no harm”
