In the United States, the amount of GMO foods that are eaten is not known, but it is reasonable to assume that it is a very high percentage. For example:
- More than 70% of all processed foods contain GMOs (probably higher now).
- A large percentage of the animals that provide meat and dairy to the grocery stores are raised in factory farms, fed GMO grain, and GMO hormones have been given to them while they were being raised.
- Almost all corn, soy, canola, and papaya sold contains GMOs, which means that almost all processed foods that contain any form of them contain GMOs.
- Due to cross contamination with GMO crops, it is possible that foods labeled "100% organic" may have small amounts if GMOs in them.
