CO HB1058

Defines "genetically engineered" as alteration of organisms at the molecular or cellular level through means not possible under natural conditions, including recombinant DNA/RNA techniques, cell fusion, gene deletion and doubling, and introduction of foreign genes.

Excludes traditional breeding, conjugation, fermentation, hybridization, in vitro fertilization, and tissue culture processes from the definition of genetic engineering.

Permits persons selling or distributing food in Colorado to label food as not containing genetically engineered material if the food contains less than one percent genetically engineered material.

Requires persons using non-GMO labels to submit an affidavit to the Department of Public Health and Environment affirming the food meets the threshold, or for raw agricultural commodities, that the food was not grown through genetic engineering and was segregated from potentially genetically engineered goods.

Treats false labeling of food as not containing genetically engineered material as misbranding, a violation of food safety law; authorizes the department to promulgate rules establishing testing methodology to determine presence of genetically engineered material.
