Arguments to ban GMOs… GMOs are hazardous because… GMOs are hazardous because… GE breaks the “species barrier”; Nature never allows genes from one species to move to another GE breaks the “species barrier”; Nature never allows genes from one species to move to another GE involves random insertions into genome GE involves random insertions into genome GE crops and foods are untested and unregulated GE crops and foods are untested and unregulated Once released, GMOs can never be recalled Once released, GMOs can never be recalled …or other claims of danger? …or other claims of danger?

USA: Theory of risk assessment Science based risk analyses Science based risk analyses Other factors applied later Other factors applied later Product vs process Product vs process rDNA processes are not inherently risky rDNA processes are not inherently risky Any breeding process may result in risky products Any breeding process may result in risky products Labelling Labelling Product composition, not process Product composition, not process

USDA/APHIS procedures Notification Notification Simplest means for least hazardous GE plants Simplest means for least hazardous GE plants Must meet six criteria (non-weedy; stable; known function; non-infectious/toxic/pharmaceutical/industrial; non-virulent; non-human or animal pathogenic source) Must meet six criteria (non-weedy; stable; known function; non-infectious/toxic/pharmaceutical/industrial; non-virulent; non-human or animal pathogenic source) Permit (for field testing release) Permit (for field testing release) More complex GE plants, requires greater scrutiny More complex GE plants, requires greater scrutiny Petition for nonregulated status (commercialization) Petition for nonregulated status (commercialization) Complete risk analysis Complete risk analysis
