Labeling of genetically engineered (GE) food may be an issue in Colorado in 2002.
the big 3
Percent of acreage
Although the number of GE crops is small, the impact is huge: an estimated 60-70% of processed foods in grocery stores include at least one GE component (mostly corn or soy).
Generally, limited to transgenic techniques, but some legislation might include breeding techniques in use for decades.
Different countries have adopted different values.
No evidence of transgenic DNA or protein has been found in meat, milk, or eggs.

May contain genetically engineered ingredients?
Information on why genetic engineering was
done, e.g., for insect resistance?
Content-based verification: Test for physical presence of foreign DNA or protein.
Analogy: vitamin content of foods.
Process-based verification: Require detailed record-keeping of seed source, field location, harvest, transport, and storage.
Analogy: shade-grown coffee.

X Virtually all commercial foods have been genetically modified.
Not genetically modified
X “Free” implies zero, which is difficult to verify.
We do not use ingredients produced using biotechnology.
This product contains cornmeal that was produced using biotechnology.
This product contains high oleic acid soybean oil from soybeans developed using biotechnology to decrease the amount of saturated fat.
“High oleic acid soybean oil” is mandatory. The rest is voluntary, and considered acceptable by FDA.
X May be misleading
This cantaloupe was not genetically engineered.
This cantaloupe, like all cantaloupes on the market, was not genetically engineered.
